Looking for the best cheap subwoofer? Subwoofers are the one category where the budget end is genuinely good, because a sub is a box, a driver and an amplifier with no tweeter, crossover or cabinet finish to pay for. Several picks below out-measure subs costing three times as much. All are chosen on CEA-2010-A burst measurements.

What You Give Up Under $500

Not as much as you’d expect, but the trade-offs are consistent:

Cabinet and finish. Budget subs use thinner panels, less bracing and vinyl wrap instead of veneer. This affects resonance a little and looks a lot.

Control and app support. Parametric EQ, room correction and phone apps are the first things cut. You get a knob for level, a knob for crossover, and a phase switch. Set the crossover on your receiver instead and this barely matters.

Deep output, sometimes. Some budget subs measure well at 40-60 Hz and collapse below 30 Hz. The picks here are chosen to avoid that, so their deep output is listed with the rest of their measurements.

Not warranty or reliability. The value brands in this range have long track records, and a subwoofer is a mechanically simple device.

The single best move at this budget: buy two of the cheaper pick rather than one of the expensive one. Two subs in different positions flatten room modes across every seat, which is a bigger improvement than any spec difference within this price range.

Best Overall Under $500

The best budget subwoofer available, out-measuring subs at three times the price, is the Monoprice SW-15: $374.99 Amazon eBay

The best subwoofer under $200 for a desk or a very small room is the Sony SA-CS9: $200 eBay

Sony SA-CS9 ranking card

Pros: Independent CEA-2010 testing records 83.7 dB at 20 Hz and 112.7 dB through 40-80 Hz. The ported, rear enclosure with 10” (254mm) driver delivers substantial upper-bass output for movie effects and music.

Cons: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 344.9H x 294.9W x 399.8D mm cabinet and 11.5 kg mass still require deliberate placement and calibration.
