Polk Audio PSW10 ($94)
Pros:
- Solid construction
- High value
- Clean and clear sound
Cons:
- No LFE input
- Might be insufficient for large rooms
Top Review Sources:
- Amazon: 4.5/5.0 (375+ reviews)
- CNET: 3.5/5.0 “It pounds out home-theater thrills and musical bass with equal prowess”
- Newegg.com: 5.0/5.0 (225+ reviews)
The low-price, high-performance Polk PSW10 makes it difficult to justify building a home theater without a powered sub. For $100, this subwoofer delivers 50 watts of continuous power through a 10-inch composite polymer speaker, producing rich bass with plenty of punch. Equally skilled at enhancing music, movies, or television, the PSW10 does its job without becoming boomy or muddled at high volumes. Its solid construction contributes to its great sound: 26 pounds of medium-density fiberboard measuring 14-3/8″ H x 14″ W x 16-1/8″ D. Included are speaker-level and line-level inputs, plus a speaker-level output. Frequency response is 35 to 200Hz. You also get on-speaker volume, crossover, and phase controls as well as an auto on/off switch. The PSW10 is built for small- to medium-size spaces. It is available in black or cherry finishes.
The Polk Audio PSW10 is currently available on Amazon.
Definitive Technology SuperCube III ($379)
Pros:
- Small package; huge bass
- Great range
- Solidly built
Cons:
- Will distort at extreme volume
Top Review Sources:
- Crutchfield: Staff Pick “True, accurate, and extremely deep bass in any room”
- Best Buy Customer Reviews: 4.5/5.0 (15+ reviews)
- Home Theater Magazine: “other SuperCube subs…have had amazingly low but very musical bass output—and lots of it. The SuperCube III is no exception”
Definitive Technology’s SuperCube III produces unbelievable bass despite its compact footprint. Its sound profile is defined by its extreme depth—all the way down to 16Hz. The SuperCube III produces an authoritative 650 watts of power, capable of handling the bass duties in small or large rooms. Listeners appreciate the SuperCube III’s versatility; it performs as well when asked to provide a steady, undistorted rumble as it does when the soundtrack demands rapid, staccato bursts of bass. Though this gloss black cube weights a substantial 25 pounds, it only measures 10-1/4 inches in any dimension. It has a signal-sensing auto on/off switch, low-pass crossover, volume control, 5-way binding post outputs, and line level, LFE, and 5-way binding post inputs. Its woofer is 7-1/2 inches in diameter.
