Your soundbar or AV receiver setup is missing the low-frequency impact that makes movies and music feel real. A dedicated subwoofer handles bass frequencies (below 80Hz) that your main speakers physically cannot reproduce at volume. Here's how to choose the right one and which models deliver the best performance per dollar in 2026.
Quick answer
- Best overall: SVS PB-1000 Pro — deep, clean bass down to 17Hz with app-based EQ tuning (~$500-600)
- Best budget: Klipsch R-120SW — punchy 12-inch driver with excellent movie impact (~$300-350)
- Best for music: REL T/5x — musical, refined bass that integrates seamlessly (~$500-600)
- Best under $150: Polk Audio PSW10 — solid entry-level bass for small rooms (~$100-130)
- Best value: Monoprice 12" 150W — surprising output for under $200
What to look for in a home theater subwoofer
Driver size matters
- 8-inch: Fine for small rooms and music-focused setups. Won't pressurize a large room.
- 10-inch: Good balance for small-to-medium rooms. The sweet spot for budget subwoofers.
- 12-inch: The standard for home theater. Handles movies, music, and gaming with authority.
- 15-inch+: For dedicated home theater rooms. Serious output but large and heavy.
Ported vs sealed
- Ported (bass reflex): Louder, deeper extension. Better for movies and home theater. Larger cabinet.
- Sealed: Tighter, more musical bass. More accurate transients. Smaller cabinet. Better for music-heavy use.
Power rating
Ignore "peak" wattage — it's a marketing number. Look at RMS (continuous) power:
- 100-150W RMS: Entry-level, fine for small rooms
- 200-325W RMS: Mid-range, handles most rooms well
- 500W+ RMS: High-performance, for large rooms or demanding listeners
Wired vs wireless connection
Most subwoofers connect to your AV receiver via a single RCA cable (LFE/subwoofer output). This is the most reliable connection.
If you're adding a subwoofer to a soundbar, you need either:
- A soundbar with a dedicated subwoofer output (wired or wireless)
- A wireless subwoofer kit (adds a wireless transmitter/receiver pair)
- A soundbar that comes with a wireless subwoofer included
Important: You generally cannot add a third-party subwoofer to a Sonos or Bose soundbar — these ecosystems use proprietary wireless connections. You need their own subwoofer (Sonos Sub or Bose Bass Module).
Our picks
SVS PB-1000 Pro — best overall
The PB-1000 Pro is the subwoofer that home theater enthusiasts recommend most. The 12-inch driver with 325W RMS amplifier delivers bass down to 17Hz — deep enough for the most demanding movie soundtracks. The SVS app gives you full control over volume, crossover frequency, phase, and parametric EQ from your phone.
Pros: Deep extension (17Hz), app-controlled EQ, excellent build quality, generous return policy from SVS direct Cons: Large cabinet (ported design), heavier than sealed alternatives (~42 lbs), overkill for very small rooms Price range: $500-600
Klipsch R-120SW — best budget
The R-120SW delivers the explosive movie impact that makes action scenes feel real. The 12-inch copper-spun driver with 400W peak / 200W continuous power handles everything from gunfire to orchestral bass. It won't reach as deep as the SVS, but for movies and gaming at this price, nothing else comes close.
Pros: Punchy movie bass, 12-inch driver at a budget price, widely available, easy setup Cons: Not as deep or refined as SVS, can sound boomy if placed in a corner without adjustment, no app control Price range: $300-350
REL T/5x — best for music
REL builds subwoofers for music first, home theater second. The T/5x uses a downward-firing 8-inch driver in a sealed enclosure for tight, fast bass that integrates seamlessly with your main speakers. The high-level input (connects to your amp's speaker terminals) is REL's secret — it lets the subwoofer match your amplifier's sonic character.
Pros: Exceptional musicality, compact size, high-level + LFE inputs, beautiful build quality Cons: 8-inch driver limits deep extension, less raw output than 12-inch competition, premium price for the driver size Price range: $500-600
Polk Audio PSW10 — best under $150
If you're on a tight budget and want to add bass to your setup, the PSW10 is the proven entry point. The 10-inch driver with 100W continuous power won't shake the walls, but it adds the low-end foundation that small speakers and basic soundbars lack. Front-firing port works well near a wall.
Pros: Extremely affordable, solid bass for small-medium rooms, easy to place, reliable Cons: 100W is modest for large rooms, won't dig as deep as larger models, basic controls only Price range: $100-130
Monoprice 12" 150W — best value
Monoprice's 12-inch subwoofer punches above its price class. The 150W amplifier and front-firing port deliver genuinely impressive output for under $200. It's not refined — the bass can be slightly loose compared to SVS or REL — but the raw value is hard to beat if you want a large driver without spending more.
Pros: 12-inch driver under $200, front-firing port, better output than similarly priced 10-inch models Cons: Less refined than name-brand competition, basic build quality, limited controls Price range: $150-200
How to set up your subwoofer
- Connect via RCA from your receiver's LFE/subwoofer output to the subwoofer's LFE input
- Set your receiver's crossover to 80Hz (the THX standard) — this tells your receiver to send frequencies below 80Hz to the subwoofer
- Set speaker size to "Small" in your receiver's speaker setup menu — this redirects bass from all channels to the subwoofer
- Run your receiver's room correction (Audyssey, YPAO, Dirac, etc.) — this calibrates levels and EQ automatically
- Place the subwoofer away from corners if possible — corner placement boosts bass but can cause boominess
For soundbar setups, follow your soundbar's instructions for adding a subwoofer. Most connect via wireless pairing or a dedicated cable.
FAQ
Can I add a subwoofer to any soundbar?
Not always. Most soundbars with a subwoofer output (wired or wireless) can pair with their own brand's subwoofer. A few support third-party subwoofers via RCA output. Sonos and Bose soundbars require their own ecosystem subwoofers — you cannot use a third-party sub.
What size subwoofer do I need?
For rooms under 200 sq ft, a 10-inch sub is sufficient. For rooms 200-400 sq ft, go with 12-inch. For rooms over 400 sq ft or dedicated home theater rooms, consider a 12-inch high-powered model or dual subwoofers.
Ported or sealed for movies?
Ported, in most cases. The extended low-frequency response and higher output of ported designs give movies more impact. Sealed subs are better if your primary use is music or if you need a smaller cabinet.
Do I need two subwoofers?
For most rooms, one properly placed subwoofer is enough. Dual subs help eliminate "dead spots" where bass cancels out in larger or oddly shaped rooms. If your single sub sounds uneven from different seats, a second sub placed on the opposite side of the room can help.
How do I connect a subwoofer to my Denon or Yamaha receiver?
Use a single RCA cable from the receiver's "Sub Out" or "LFE" jack to the subwoofer's LFE input. Set speaker sizes to "Small" in the receiver menu and crossover to 80Hz. Run your receiver's room correction for automatic calibration.
