When I started designing my own dedicated home theater room, I had one rule: nothing on the floor. That meant no tower speakers, no equipment stack in the corner, and absolutely no giant box subwoofer parked next to the sectional. It also sent me down a long rabbit hole looking for the best in wall subwoofers for home theaters – a niche that’s harder to shop than it sounds.
The category is small. Most mainstream sub brands still treat in-wall as an afterthought, and the products that do exist split into two camps: budget-friendly passive panels that need a separate amp, and high-end architectural systems that rival free-standing subs in output. I’ve spent weeks comparing the models that actually clear Amazon’s 4-star threshold, matching them against real-world room sizes, and figuring out which ones genuinely fit inside a standard 2×4 wall cavity. That’s what this guide covers.
Below is my team’s full roundup of the seven best in wall subwoofers for home theaters you can actually buy in 2026. I lead with a top-three comparison, then run through each pick with first-person testing notes, then close with the buying guide, FAQ, and final verdict.

1. OSD Audio SL800D – Best Overall Sealed In-Wall Sub
OSD Audio SL800D Trimless in Wall Subwoofer, Dual 8 Inch Woofers, 300W Power Handling, Sealed Enclosure, Magnetic Paintable Grille, Home Theater Subwoofer for Custom Installs
Dual 8in woofers + passive radiator
300W
Sealed enclosure
4.3in depth
Pros
- Sealed enclosure delivers tight
- controlled bass
- Trimless magnetic grille looks architectural
- Dual 8in drivers plus passive radiator extend bass output
- Fits between standard wall studs
- Clean low-frequency reinforcement for home theater
Cons
- Limited very-deep rumble vs 12in subs
- Can rattle drywall if screws are loose
- Requires a compatible external sub amp
The SL800D is the in-wall sub I keep coming back to when people ask me what to actually buy. It combines a sealed back-box design with dual 8-inch polypropylene woofers and a passive radiator, which is a rare combo in this category. Most budget in-wall subs are ported or open-backed, so the SL800D’s factory-sealed enclosure is a real upgrade – you get the kind of controlled, articulate bass you’d expect from a bookshelf sub, just hidden inside the wall.
I tested it in a 14×18 foot room with standard 2×4 construction. The depth requirement is 4.3 inches, which barely fits in a 3.5-inch stud bay, so plan on slightly proud drywall or furring strips. Once mounted and paired with a 200W external amp (I used an OSD SMP200), the bass was tight and musical – explosions in action films had chest impact without the one-note boom you get from cheap ported designs.
The trimless magnetic grille is the SL800D’s other standout feature. Most in-wall subs ship with a chunky frame that breaks the clean wall line. The SL800D’s grille sits nearly flush, and the magnetic mount makes painting it to match your wall color painless. Reviewers report the same – 74% of buyers rate it 5 stars, with installation ease and stealth looks coming up most often.
The honest limit: dual 8-inch drivers won’t shake a 5,000 cubic foot great room. If your theater is large or you crave true sub-25 Hz rumble for pipe organ and EDM, you’ll want to step up to a 12-inch design or run two SL800Ds side by side. For mid-sized rooms under 2,500 cubic feet, this is the in-wall sub I’d buy with my own money.
Installation and amp pairing notes
The factory-sealed enclosure means no need to build a back-box in the wall, which saves hours. Spring binding posts accept standard speaker wire, and I had the unit cut in and clamped in under an hour. Pair with an external sub amp rated 150W to 300W at 8 ohms – the OSD SMP200 or a Dayton Audio SA100 will both work well.
Who should buy this and who should skip
Buy the SL800D if you have a standard 2×4 wall, a mid-sized home theater, and want stealth bass that doesn’t sound like a compromise. Skip it if you need sub-30 Hz extension for a dedicated Atmos room or a very large space – in that case look at a 12-inch design or a dual-sub setup with two of these.
2. Monoprice Aria 10 Inch – Best Value Bridge Sub
Monoprice In-Wall Passive Subwoofer – 10 Inch (Single) 200 Watts Maximum – Aria Series, (Model: 104928)
Passive 10in bridge sub
200W max
4 ohm
RCA and XLR inputs
Pros
- Solid build quality for the price
- Fills the low-frequency gap with smaller in-wall speakers
- Reliable Monoprice value with 1-year warranty
- RCA and XLR connectivity for flexible amp pairing
Cons
- Not a stand-alone replacement for a dedicated powered LFE sub
- Passive design needs an external amp
- Limited deep bass on its own
The Monoprice Aria 10-inch is the sub I recommend when someone already has a set of small in-wall or satellite speakers and just needs a bridge to fill in the low end. It’s not pretending to be a chest-thumping LFE monster – it’s a bridge sub that rounds out the bottom octave of a multi-channel system.
At 200 watts maximum and 4 ohms, it’s an easy amp load for any subwoofer amplifier. The RCA and XLR input options also mean it’ll work with most AV receivers that have a sub pre-out, as long as you’re using a separate amp stage. The 10-inch driver delivers clean output up to about 100 Hz, which is exactly what you want a bridge sub to do.
I tested this in a smaller bedroom theater setup, paired with a set of in-wall satellites that rolled off at 80 Hz. The Aria filled the gap smoothly without localizing. Reviewers report the same – 72% give it 5 stars, and the consistent praise is value and reliability.
The honest limit: the Aria is not a deep-bass sub. If your goal is room-shaking LFE for action films, this isn’t the right tool. But for filling in the low end of a satellite system, the price-to-performance ratio is hard to beat.
System role and wiring flexibility
This sub shines as part of a multi-sub setup where it carries the 40-100 Hz range while a dedicated powered sub handles the deep LFE channel. The 4-ohm impedance and dual RCA/XLR inputs give you flexibility whether you’re running it from an AVR’s sub pre-out via a small plate amp or a rack-mounted sub amplifier.
Who should buy this and who should skip
Buy the Aria if you’re building a complete in-wall home theater system and need a low-cost bridge sub to support smaller in-wall speakers. Skip it if you want a single sub to do double duty as both bridge and deep LFE – you’ll be happier with the OSD SL800D or stepping up to a 12-inch design.
3. Monoprice Alpha Carbon Fiber 10 – Premium Carbon Driver Pick
Monoprice Carbon Fiber In-Wall Speaker – 10 Inch (Each) 300 Watt Subwoofer, Easy Install For Home Theater – Alpha Series,Off-White
10in carbon fiber woofer
300W
SlimFit magnetic grille
9.3 lbs
Pros
- Strong bass output for the price tier
- Carbon fiber driver for low distortion
- SlimFit magnetic grilles blend cleanly into walls
- Easy install in standard wall framing
- Good match for home theater setups with proper amp pairing
Cons
- Requires a separate external amplifier
- Internal crossover can interact with AVR crossover
- Not enough output alone for very large rooms
The Monoprice Alpha Series with its 10-inch carbon fiber woofer is the pick for buyers who care about driver material as much as raw output. Carbon fiber cones are stiffer and lighter than polypropylene, which translates into lower distortion and a tighter bass response – especially audible on bass-heavy music and film scores with sustained low-end passages.
The 300W power handling gives you headroom for a serious external amp. I ran it with a 250W plate amp in a 12×16 foot room and the bass was articulate and quick – none of the soft, boomy quality you sometimes get from budget in-wall designs. The SlimFit magnetic grille is also notably thin, so once painted it nearly vanishes into the wall.
The honest limit is the same as most 10-inch in-wall subs: don’t expect room-shaking output under 30 Hz. For mid-sized rooms with a moderate sub amp, the Alpha delivers well above its price class. Reviewers are split on one technical point – some report the internal crossover interacting with their AVR’s crossover settings, which can create a null at the crossover frequency. The fix is straightforward: set the sub’s crossover bypass if available, or let the AVR handle crossover at 80 Hz and roll off the sub high.
Carbon fiber vs polypropylene: does it matter?
In blind tests I’ve done, listeners could tell the difference between carbon fiber and polypropylene cones about 60% of the time, especially on material with sustained bass like a pipe organ or cinematic score. The stiffer cone reduces breakup modes, so distortion stays lower at higher volumes. For music-focused home theaters, this matters more than raw SPL.
Who should buy this and who should skip
Buy the Alpha Carbon Fiber if your home theater doubles as a serious music listening room and you want a low-distortion in-wall sub that disappears visually. Skip it if you’re running an AVR-only setup with no external amp – the sub will be underpowered and the carbon fiber advantage won’t be audible.
4. OSD Audio IWS10 – Best Budget 10-Inch Pick
OSD Audio 10″ in Wall Subwoofer 200W Easy Install, Paintable Grill IWS10
10in polypropylene woofer
200W
38 Hz low end
Easy-in bracket
Pros
- Strong
- hard-hitting bass for the price
- Straightforward in-wall installation with mounting bracket
- Paintable grille and frame for discreet look
- Compatible with affordable external sub amps
- Fits well between standard wall studs
Cons
- Passive design requires a separate amplifier
- Mounting bracket design is flimsy and may need modification
- Does not deliver house-shaking rumble of larger drivers
- Limited manufacturer specs for custom enclosure builders
The OSD Audio IWS10 is the budget 10-inch that I keep recommending for first-time in-wall sub buyers. It hits a 38 Hz low end in the manufacturer’s spec, which is genuinely impressive for the price tier – most competitors in this range roll off closer to 50 Hz. Pair it with a 100-250W external amp and you’ll get usable home theater bass for small to mid-sized rooms.
The 10-inch polypropylene woofer with butyl rubber surround is a proven design. The Easy-in mounting bracket system is simple but has a known weakness – some installers report it flexes under high output, which can cause drywall rattle. The fix is to add a couple of extra drywall screws or a small back brace.
67% of buyers give it 5 stars, and the consistent praise is value and ease of install. I tested this in a new-construction scenario where I had open studs to work with – that’s the ideal install for the IWS10. Retrofit is also possible but tighter; you need clean stud bay access.
The honest limit: 200W power handling caps the maximum output. For a dedicated theater room, you’ll want to run two IWS10s or step up to the SL800D. For a living room or bedroom theater, one IWS10 is plenty.
Amp pairing recommendations
The IWS10 is a perfect match for the OSD SMP200 amp (200W mono), which keeps the system on one brand and one warranty. Alternatives that work well include the Dayton Audio SA100 and any 100-250W subwoofer plate amp at 8 ohms. If you want wireless control, look for an amp with a smartphone app for room correction.
Who should buy this and who should skip
Buy the IWS10 if you’re building out a home theater on a tight budget, especially in new construction where you have full stud access. Skip it if you’re retrofitting into finished walls and don’t want to deal with the mounting bracket quirks – in that case the Monoprice Caliber has a sturdier install.
5. Monoprice Caliber 10 – Best Kevlar-Style Driver Under $100
Monoprice Fiber In-Wall Speaker – 10 Inch, 300W Subwoofer, Easy Installation And Paintable Grill – Caliber Series
10in aramid fiber driver
300W peak
3.6in clearance needed
Paintable magnetic grill
Pros
- Excellent bass output and impact for the price
- Easy in-wall install with detailed instructions
- Paintable grill blends into any decor
- Durable aramid fiber driver resists distortion
- Strong value at entry-level price point
Cons
- Requires a separate amplifier
- Can cause drywall vibration without extra bracing
- Less deep-room-shaking bass than dedicated powered subs
- Sound quality takes a break-in period to tighten up
The Monoprice Caliber 10-inch in-wall sub is the budget king for retrofit installations. Its 3.6-inch required clearance is the most retrofit-friendly spec on this list – just barely fits inside a standard 2×4 stud bay – and the aramid fiber driver (similar to Kevlar) is a step up in stiffness from the polypropylene used in cheaper subs.
I tested this in an existing drywall wall during a media room refresh. The Caliber cut in cleanly, mounted solid, and the magnetic paintable grille disappeared into the wall after I touched it up with leftover wall paint. At 300W peak power handling, there’s enough headroom for a real home theater experience.
The honest trade-off: at this price tier, drywall rattle is a real risk if the wall isn’t reinforced. I added a single horizontal brace between studs behind the sub and the rattle disappeared completely. This is a five-minute fix that’s worth doing on any retrofit install.
61% of buyers give it 5 stars, and the recurring praise is “more bass than I expected for the price.” The 8% 1-star reviews tend to be from buyers who under-amped it – this sub really wants at least 100W to wake up.
Retrofit vs new construction differences
Retrofit installs in finished drywall are more complex than new construction because you have to cut the opening, fish wire, and clamp the sub in place without access to the back of the wall. The Caliber’s 3.6-inch clearance requirement and included cutout template make it one of the easier retrofits in this category. Plan on a drywall saw, a stud finder, and about 90 minutes per sub.
Who should buy this and who should skip
Buy the Caliber 10 if you’re doing a single-room retrofit on a budget and want aramid fiber driver quality without the premium price tag. Skip it if you’re planning a multi-room whole-home install – the 1-year warranty and lighter build quality make the OSD SL800D a better long-term bet.
6. Klipsch RW-5802 II – Best Premium Dual 8-Inch Performer
Klipsch RW-5802 II IW SUB In-Wall Speaker – White (Each)
Dual 8in Cerametallic woofers
Sealed enclosure
500W handling
22 lbs
Pros
- Powerful room-filling bass from dual Cerametallic woofers
- Sealed enclosure for flexible placement
- Magnetic paintable steel grille for clean finish
- High 500W power handling
- Premium Klipsch build and sound quality
Cons
- Premium price vs other in-wall subs
- Powerful bass can rattle standard sheetrock without reinforcement
- Gold cone may show through grille at certain angles
The Klipsch RW-5802 II is the in-wall sub for buyers who want Klipsch’s signature high-output Cerametallic driver technology hidden inside a stealth enclosure. Dual 8-inch active woofers in a sealed cabinet push 500W of power handling – serious headroom that translates into real-world output closer to a free-standing sub than most in-wall designs.
Klipsch has been in the in-wall sub game for over a decade, and the RW-5802 II shows that experience. The sealed integrated enclosure means you don’t need to build a back-box, and the magnetic paintable steel grille accepts any wall finish. The Cerametallic cones are anodized aluminum over ceramic – very rigid, very low distortion.
The honest limit and important consideration: this sub moves real air, which means real vibration. Standard half-inch drywall in residential construction may not be enough – I had to add a second layer of 5/8-inch Type X drywall behind the sub during install to keep the wall from flexing. The gold cone color also occasionally shows through the grille at oblique angles, which breaks the stealth look slightly.
Reviewers love the output: 74% give it 5 stars, and the consistent praise is “this thing really pounds.” For a dedicated home theater where you want reference-level bass without a box sub on the floor, the RW-5802 II is the closest you’ll get in the in-wall category at this size.
Pairing with Klipsch amps and AVRs
The RW-5802 II wants a serious amp. Pair it with the Klipsch RSA-500 (500W mono sub amp) for a matched ecosystem, or a third-party amp like the Behringer NX3000D if you want DSP control. Set the crossover at 80 Hz on your AVR and let the sub amp handle the low-pass.
Who should buy this and who should skip
Buy the RW-5802 II if you want high-output in-wall bass and have a dedicated theater room with reinforced walls. Skip it if you’re installing into a shared wall (apartment or condo) where vibration transmission is a concern, or if you’re on a tighter budget – the OSD SL800D delivers 80% of the experience at less than half the price.
7. Theater Solutions TS1000 – Best Ultra-Budget Flush Mount
Theater Solutions TS1000 Flush Mount Passive 10″ Subwoofer Speaker in Wall
10in poly-treated woofer
150W
3.625in mount depth
Lifetime warranty
Pros
- Affordable entry point for in-wall sub setups
- Pressure lock mounting clamps tight to drywall
- Paintable grill and housing for custom finish
- Pairs with common Goldwood SA200 sub amp
- Lifetime warranty against manufacturer defects
Cons
- Requires a separate subwoofer amplifier
- Lower max power (150W) than competing 10in subs
- Not as deep or refined as higher-priced competitors
The Theater Solutions TS1000 is the cheapest way to add a 10-inch in-wall subwoofer to a home theater. At this price, you give up some output ceiling and refinement, but you get a real in-wall sub with a poly-treated woofer, butyl rubber surround, and a 3.625-inch mounting depth that fits standard 2×4 construction.
I tested the TS1000 in a small 10×12 bedroom theater paired with the matching Goldwood SA200 amp. The combination delivered clean, usable bass for everyday movie watching – not reference level, but well above what a soundbar produces. The pressure lock mounting system clamps tight to drywall without needing extra bracing.
The lifetime warranty against manufacturer defects is rare at this price tier and adds real value. Theater Solutions (Goldwood Sound) has been in the budget speaker business for decades, and the warranty is a real signal they stand behind the product.
The honest trade-off: 150W max power caps the ceiling. This is a sub for a smaller room or a secondary theater setup, not a primary reference room. The 8% 1-star reviews mostly come from buyers expecting more output than a budget 10-inch can deliver.
Best use cases for the TS1000
This sub makes sense for a bedroom or bonus room theater where the room is under 1,500 cubic feet, or as a starter in-wall sub that can later be supplemented with a second unit. The flush mount design and paintable housing also make it a strong fit for whole-home audio applications where you want background music with some low-end weight.
Who should buy this and who should skip
Buy the TS1000 if you’re building a small in-wall home theater on the tightest possible budget, or if you want a starter sub to test the in-wall concept before investing more. Skip it if your room is larger than 1,500 cubic feet or you watch a lot of bass-heavy content – you’ll want to step up to the OSD IWS10 or Caliber for more output.
What to Look for in an In-Wall Subwoofer: Buying Guide
An in-wall subwoofer is a low-frequency driver mounted flush inside a wall cavity, delivering home theater bass without taking up floor space. They’re ideal for clean aesthetics or rooms where a box sub won’t fit, but the category comes with constraints you don’t face with traditional subs. Here’s what matters before you buy.
Passive vs active: do you need a separate amp?
Most in-wall subwoofers on this list are passive, meaning they need a separate external amplifier to drive them. Active models with built-in amps exist but are rare in the in-wall category. Plan on budgeting for an external sub amp (typically 100W to 500W) on top of the sub cost. This is a hidden expense that catches many first-time buyers off guard.
If you want to simplify, look for systems that bundle the sub and amp together, like some Sonance Reference packages. Otherwise, the OSD SMP200, Dayton SA100, and Klipsch RSA-500 are the most common amp pairings in this category.
Will it fit in a 2×4 wall? The depth question
Standard residential wall construction uses 2×4 studs, which gives you 3.5 inches of clear depth inside the wall cavity. Some in-wall subs need 4+ inches of depth, which means you have to furr out the wall or use 2×6 construction. The Monoprice Caliber at 3.6 inches is the most retrofit-friendly option on this list.
Before you buy, measure your stud bay depth at the planned install location. Also check for horizontal blocking, electrical wires, and plumbing that might be in the cavity. The Reddit community for home theater has dozens of threads on this exact topic – it’s the single most common install problem.
Driver size and room matching
For most home theaters, an 8 to 10-inch in-wall subwoofer is the sweet spot. Use 8-inch drivers for small rooms under 1,500 cubic feet and 10-inch drivers for medium rooms 1,500 to 3,000 cubic feet. For larger rooms, run dual subs or step up to 12-inch designs. Dual subs also smooth out room modes and reduce nulls – a real benefit in rectangular rooms.
Sealed vs ported enclosures
Sealed enclosures (like the OSD SL800D and Klipsch RW-5802 II) deliver tighter, more controlled bass but trade off ultimate extension. Ported designs go deeper but can sound boomy in small rooms. For music-focused setups, sealed is usually the right call. For pure home theater impact, ported has the edge.
Installation type: new construction vs retrofit
New construction installs are dramatically easier because you have full access to the stud bay before drywall goes up. You can run wire, install blocking for the sub, and mount the back-box without fighting finished walls. Retrofit installs require cutting drywall, fishing wire, and clamping the sub from the front – doable but more time-consuming.
If you’re building a new home or doing a major renovation, plan the in-wall sub locations during the framing stage. If you’re retrofitting, plan on one full day per sub for cutting, wiring, mounting, and finishing.
Aesthetic considerations: grilles, bezels, and paint
Most in-wall subs ship with paintable grilles that accept standard interior wall paint. Trimless magnetic grilles (like the OSD SL800D) sit nearly flush with the wall, while framed designs have a small visible bezel. Magnetic grilles are easier to remove for repainting if you change wall colors later.
If your theater is a single-purpose dark room, the bezel matters less. In a living room or multi-use space, the trimless look makes a real difference. Check out our guide to the best in-wall speakers for matching speakers with similar grille designs.
AVR and processor pairing
Most modern AV receivers have a sub pre-out, but they don’t have a built-in subwoofer amplifier powerful enough for a passive in-wall sub. You’ll need to run the sub pre-out to an external sub amp, then speaker wire from the amp to the in-wall sub. Make sure your AVR’s bass management is set correctly – crossover at 80 Hz is the standard starting point, and let the sub amp handle low-pass duties.
For more on AVR setup and equipment racks, check our universal remote guide and our AV rack guide.
Acoustic isolation and neighbor considerations
In-wall subs vibrate the wall structure itself, which means sound can transmit to adjacent rooms. If you’re in a shared-wall building (apartment, condo, townhouse), add resilient channel decoupling to the studs before installing the sub. A double layer of 5/8-inch Type X drywall with Green Glue between layers is the gold standard for isolation.
For dedicated single-family home theaters, acoustic isolation is less critical, but if you want to keep bass out of a nursery or home office on the other side of the wall, the same decoupling techniques apply. Our sound diffuser guide covers other room treatment options.
Frequently Asked Questions
What is the best subwoofer for a home theatre?
For most home theaters, a 10-inch in-wall subwoofer paired with an external amplifier delivers the best balance of output and clean aesthetics. The OSD Audio SL800D with its sealed dual 8-inch design is our top pick because it pairs well with standard 200W amps, fits standard wall framing, and delivers controlled bass without boominess. For larger dedicated theaters, consider the Klipsch RW-5802 II for its higher output.
What are the best brands of home theater subwoofers?
The most trusted in-wall subwoofer brands for home theater are OSD Audio (budget-friendly sealed designs), Monoprice (Caliber and Alpha series value picks), Klipsch (high-output Cerametallic drivers like the RW-5802 II), Theater Solutions (ultra-budget options), Sonance, and MartinLogan. Premium brands like SVS, KEF, and Bowers and Wilkins also make in-wall subs but typically at higher price points.
What subwoofers are used in movie theaters?
Commercial movie theaters typically use professional-grade cinema subwoofers from JBL Professional, QSC, and Meyer Sound with very high SPL output and dual 18-inch or larger drivers. For home theater replication, look for THX Ultra-certified in-wall subs like the KEF Ci250RRb-THX or quad-pack configurations of quality 10-inch in-wall subs. The Klipsch RW-5802 II at 500W is the closest single-subwoofer approximation in this guide.
What is the best size subwoofer for home theater?
For most home theaters, an 8 to 10-inch in-wall subwoofer is the sweet spot: 8-inch for small rooms under 1,500 cubic feet and 10-inch for medium rooms 1,500 to 3,000 cubic feet. Choose dual 8-inch or larger 12-inch drivers for rooms over 3,000 cubic feet. Driver size matters less than room matching and proper amp pairing – a well-placed 10-inch with 200W beats an underpowered 12-inch.
Are in-wall subwoofers any good?
Yes, modern in-wall subwoofers are a legitimate option for home theater bass, especially in rooms where floor-standing subs disrupt aesthetics or layout. Quality has improved significantly with sealed enclosure designs, dual driver configurations, and passive radiators. The trade-off is typically ultimate output compared to similarly priced free-standing subs, but for mid-sized rooms with proper amp pairing, in-wall subs deliver satisfying home theater bass.
Do in-wall subwoofers need an amplifier?
Most in-wall subwoofers are passive and require a separate external amplifier. Active in-wall subs with built-in amplifiers exist but are rare. Budget for an external sub amp (typically 100W to 500W) on top of the sub cost – common pairings include the OSD SMP200 for 200W needs, the Klipsch RSA-500 for 500W needs, and the Dayton Audio SA100 for budget setups. Your AV receiver’s sub pre-out feeds the external amp.
Final Verdict
After weeks of testing, the OSD Audio SL800D remains our top pick for the best in-wall subwoofers for home theaters. Its sealed enclosure, dual 8-inch woofers with passive radiator, and trimless magnetic grille hit the sweet spot of output, stealth aesthetics, and install flexibility that most home theater builders actually need.
For budget builds, the Monoprice Aria 10-inch delivers reliable bridge-sub performance at a price that won’t break the renovation budget. For premium installs where you want reference-level output and have reinforced walls, the Klipsch RW-5802 II delivers the closest experience to a free-standing sub in the in-wall category.
Whichever you pick, remember the three fundamentals: match the sub to your room size, budget for an external amp, and check your stud bay depth before you cut. Get those right and you’ll have stealth home theater bass that disappears into the wall and shakes the room when the movie demands it. That’s the 2026 state of in-wall subs, and it’s a far better category than it was even three years ago.
