The Best Wireless Subwoofers

The force-canceling design is the whole reason this one works in a real house. Two Sonos-engineered drivers face each other inside the cabinet, so their motion cancels out instead of transferring into your floor. That matters more than it sounds. On hardwood or laminate, a single-driver sub buzzes the floorboards and rattles anything on a nearby shelf. This one stays put and lets you turn it up without a neighbor complaint.

Setup is the part you'll appreciate most. There's no crossover dial, no phase switch, no separate remote to lose in the couch. You add it in the Sonos app, it finds your soundbar over WiFi, and it sets its own crossover to match. If you've ever spent an evening guessing at subwoofer settings on a receiver menu, this feels like cheating.

The ported enclosure trades a little tightness for a lot more output. Sonos went this route to push low-frequency response further down and louder than a sealed box of the same size could manage. For movies, that's the right call. Big room-filling rumble is what you want during a chase scene, and the Sub 4 has plenty of it for a typical living room.

Placement is where wireless earns its keep. Crutchfield's placement guidance notes that moving a sub a few feet often changes perceived bass more than jumping to a higher-wattage model. Because this one only needs power, you can slide it into a corner, stand it behind an armchair or lay it flat under a console. Try three spots in an evening and keep the one that sounds best.

Flaws but not dealbreakers

It only works with Sonos. Pair it with an Arc, Arc Ultra or Beam and you're set, but it won't connect to a Samsung, LG or Vizio soundbar, and it won't join a traditional AV receiver. Buying this sub is really a decision to stay in the Sonos ecosystem.

It's also the most expensive proprietary sub in this guide, and the size is real. At roughly 16 inches tall and wide, it's a piece of furniture, not something you hide behind a plant. Small apartments may be better served by the Sub Mini.

Sealed cabinets sound tighter, and that's the point here. SVS built the SB-1000 Pro as a sealed box with a high-excursion 12-inch driver and a 325-watt RMS amplifier rated past 820 watts peak. Sealed designs roll off more gently and control the driver more precisely, so bass notes start and stop where the music does. If you listen to a lot of acoustic bass or kick drum, you'll hear the difference.

The 50MHz Analog Devices DSP is what separates this from a soundbar sub. You get real in-room tuning controls rather than a single volume knob. RTINGS.com's methodology emphasizes room-corrected in-room response over headline wattage when comparing subs, and this is one of the few units here that gives you the tools to actually do that correction yourself.

The SoundPath adapter is the piece worth understanding. It's a transmitter and receiver pair that carries full-range audio to any powered subwoofer at ranges up to roughly 50 feet through typical home construction. So it's not just for this sub. If you already own a decent wired subwoofer sitting in the wrong spot, the same adapter frees it.

You give up automatic setup for control. There's no app that measures your room and dials things in for you, so you'll spend an evening with the crossover and gain. That's the trade audiophiles want and most people don't.

Flaws but not dealbreakers

This is the most involved setup in the guide. You're connecting a transmitter to your receiver's sub output, matching levels and choosing a crossover point by ear. Anyone expecting a five-minute soundbar experience will find it fussy.

The listing description is inconsistent about driver size, calling it both a 12-inch and a 10-inch sub in different places. Confirm the exact model before you order if driver size matters to you.

It's also physically the most demanding pick. A sealed cabinet with a long-throw driver is heavy and dense, and it needs a bit of breathing room from the wall to sound its best.

If you live in an apartment, this is the Sonos sub to buy. It's under a foot tall and about nine inches across, so it fits beside a media console or under a side table. The sealed cabinet keeps output controlled rather than boomy, which is exactly what you want in a room where the walls are close and the floor is somebody's ceiling.

Both woofers face inward, same force-canceling trick as the bigger Sub. That's the feature that keeps a sub from buzzing a hardwood floor or rattling a bookshelf. In a small room you tend to sit closer to the sub, so cabinet noise is more noticeable. This design largely removes it.

Trueplay tuning matters more here than on a larger sub. Small rooms create nasty bass peaks, especially when a sub sits against a wall. Trueplay adapts the response to your room so it doesn't turn muddy or harsh. You'll need an iOS device to run it, which is a genuine annoyance for Android households.

It's roughly half the size of the Sub 4 and costs meaningfully less. For a bedroom, a studio or a small living room, the bigger sub is more output than you'll ever use at a neighborly volume.

Flaws but not dealbreakers

It pairs with Beam and Ray, and like the rest of Sonos it won't work with another brand's soundbar. If you're not already in the ecosystem, that's a hard limit.

There's less raw extension than the Sub 4 or the SVS. In a large open-plan room you'll notice it running out of headroom during big movie scenes. It's built for small spaces and it stays honest about that.

You're buying a system, not a sub. That's the whole appeal. If your TV audio is still coming from the TV, this replaces it entirely with a seven-driver bar, a dedicated center channel and a wireless sub for less than the price of most standalone subs here.

Setup is genuinely one cable. Plug the bar into your TV's HDMI port, plug in the sub, and the two find each other. Polk says most people are running in under five minutes, and that matches what owners describe. There's no app to configure and no pairing dance.

The bar is 2.36 inches tall, so it sits in front of a TV without blocking the bottom of the screen or the remote sensor. Up-firing elevation drivers handle the Atmos height channels. It's not the same as ceiling speakers, but on a normal-height ceiling you get a sense of sound above you.

VoiceAdjust is the feature people actually use daily. Dialog gets buried in modern mixes, and this lets you push voices up without raising everything else. Bass Adjust does the same on the low end when a neighbor is home.

Flaws but not dealbreakers

The 5.9-inch driver is small, and physics doesn't negotiate. You'll get noticeably more presence than a soundbar alone, but not the chest-hitting rumble of the 10- and 12-inch subs in this guide. Deep organ notes and the lowest movie effects mostly aren't there.

The sub isn't sold as a standalone upgrade path either. You're buying it as part of the Signa S4 system, so it isn't a way to add bass to a soundbar you already own.

The shape is the selling point. It's a 10-inch cube built from premium materials, small enough to sit beside a cabinet or behind a chair without looking like audio equipment. Most subs are a compromise you hide. This one you can leave out.

Pairing with a Bose soundbar takes about a minute. It connects wirelessly to the Smart and Ultra bars, so there's no cable run and no menu diving. You plug it in, the bar finds it, and you're done. For anyone who bought a Bose bar precisely because they didn't want to think about audio setup, that consistency is worth something.

For a cube this size, the output is more than you'd guess. Bose tuned it to fill a normal living room rather than chase the lowest possible frequency, which is the right priority for TV and movies in an average space.

Owner feedback on this one splits more than the Sonos subs. Most people are happy, but a visible minority report pairing frustrations or units that stop connecting. It's worth buying somewhere with an easy return window.

Flaws but not dealbreakers

It only works with Bose soundbars. Outside that ecosystem it's a paperweight, and even inside it you need one of the compatible bars rather than any Bose speaker.

A 10-inch cube can only move so much air. Compared with the SVS or the Sonos Sub 4, it runs out of depth sooner during heavy movie scenes. It fills a room pleasantly rather than pressurizing it.

The reliability picture is the real caution here. A meaningful slice of owner feedback describes connection dropouts or early failures, which is unusual among the subs in this guide.
