Every Monoprice Subwoofer Ranked

Last updated: September 8, 2026

This page lists all 25 Monoprice subwoofers ranked on this site, each showing where it places in its size class, ranked on CEA-2010-A burst measurements.

Monoprice is the value benchmark this site measures other subwoofers against. The SW-15 costs about $375 and out-measures subwoofers at three times the price. The Monolith line goes considerably further: the M-15 V2 and M-215 deliver deep output that competes with boutique designs costing several times more. Not one Monoprice subwoofer in the store is marked discontinued, which is unusual for a value brand.

Where the money was saved. Cabinet finish is vinyl rather than veneer, panels are thinner and less braced than the boutique competition, and the control set is basic: level, crossover, phase, and not much else. There is no app, no parametric EQ and no room correction on the cheaper models. If you set the crossover on your receiver, which you should, most of that hardly matters.

Two names, one brand. Plain Monoprice models (SW-12, SW-15, Premium Select) are the budget line. Monolith is the serious line, and the M-series competes on output with anything mainstream.

The best use of a Monoprice budget is two subwoofers. Two subs in different positions average out room modes and flatten response across every seat, which is a larger improvement than anything you can buy by spending the same money on one better cabinet. The full argument is in the subwoofer buyer’s guide.

Small Size Powered Bookshelf Speakers

Ranked #14 of 22 in Small Size Powered Bookshelf Speakers - Monoprice Monolith MM-3: $299.99/pair Monoprice eBay

Monoprice Monolith MM-3 ranking card

Pros: With the ports plugged, Erin’s Klippel data yields preference scores of 3.21 standalone and 5.63 with an ideal subwoofer, and a measured -3dB point around 62Hz. The reviewer found blocking the ports improved the bass peak and midrange resonances. Bluetooth, analog inputs, a headphone jack and angled stands provide a convenient compact desktop package.

Cons: These measurements describe modified, port-plugged speakers, not the stock product. Even in that configuration the review identifies substantial tonal problems and recommends off-axis placement to reduce excess treble. The score therefore does not justify ranking the stock MM-3 alongside better-balanced monitors. Small drivers limit its application, and the proprietary inter-speaker cable complicates replacement.

Ranked #22 of 22 in Small Size Powered Bookshelf Speakers - Monoprice DT-3: $139.99/pair Monoprice eBay

Monoprice DT-3 ranking card

Pros: An inexpensive, compact powered pair with front volume control, auxiliary input and headphone output. Erin’s Klippel measurements put the -3dB bass point around 74Hz, sufficient for some upper-bass content at a desk.

Cons: The measured response spans 7.6dB from 300Hz to 5kHz, with large irregularities both on-axis and across the listening window. Preference scores are -0.17 standalone and only 2.76 with an ideal subwoofer, the weakest comparable result in this group. That means adding bass support does not remove its major tonal problems. It offers little reason to choose it for accurate listening over better-measuring budget alternatives.

Small Powered Home Subwoofers (Under 30 lbs)

Monoprice Premium Select 8in 200-Watt ranking card

Pros: 8-inch ported driver still manages 106.4dB CEA-2010-A average at the lowest price of any subwoofer tested in this weight class. An easy entry point for a first subwoofer.

Cons: Very compact 8.4 kg size, limited 106.4 dB output, ported room interaction, and entry-level build.

Ranked #37 of 42 in Small Powered Home Subwoofers (Under 30 lbs) - Monoprice Monolith 8 THX Certified: $350 eBay

Monoprice Monolith 8 THX Certified ranking card

Pros: A compact 9kg, ported 8-inch subwoofer with THX certification that can suit a small room or satellite-based system without taking much floor space. Measured output is useful through the upper bass: 99.3dB at 50Hz, 100.7dB at 63Hz and 101.6dB at 80Hz. Its selectable THX/EQ modes provide a more controlled option for music than the extended setting.

Cons: Deep-bass output is modest for a home-theater subwoofer, falling to 72.9dB at 20Hz and 86.1dB at 25Hz. It will not deliver the infrasonic impact or room-filling output of a larger model, and the manufacturer lists it as out of stock. Choose it for compactness and moderate listening levels, not for demanding cinema effects.

Ranked #62 of 97 in Large Powered Home Subwoofers (Over 75 lbs) - Monoprice Monolith M15-S: $999 eBay

Monoprice Monolith M15-S ranking card

Pros: Published CEA-2010 specifications list 105.6 dB at 20 Hz and 119.0 dB through 40-80 Hz. The sealed enclosure with 15” (381mm) driver has the headroom for demanding film bass in a large room.

Cons: The 596.9H x 424.2W x 500.4D mm cabinet and 36.3 kg mass make this a serious placement and moving commitment. A sealed cabinet still needs careful placement and calibration to avoid room-mode peaks.

Ranked #76 of 97 in Large Powered Home Subwoofers (Over 75 lbs) - Monoprice Monolith M-210: $1,300 eBay

Monoprice Monolith M-210 ranking card

Pros: Independent CEA-2010 testing records 101.4 dB at 20 Hz and 117.5 dB through 40-80 Hz. The ported, front enclosure with 2x 10” (254mm) drivers 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 924.6H x 449.6W x 599.4D mm cabinet and 73.5 kg mass still require deliberate placement and calibration.

Ranked #83 of 97 in Large Powered Home Subwoofers (Over 75 lbs) - Monoprice Monolith 12 THX Ultra: $1499 eBay

Monoprice Monolith 12 THX Ultra ranking card

Pros: Independent CEA-2010 testing records 108.4 dB at 20 Hz and 115.2 dB through 40-80 Hz. The ported, front enclosure with 12” (305mm) driver has the headroom for demanding film bass in a large room.

Cons: The 579.1H x 424.2W x 599.4D mm cabinet and 44.7 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.
