Polk Audio DSW PRO 400 review: Polk Audio DSW PRO 400

Connectivity covers all the usual bases: stereo speaker (five-way binding posts) and line-level (RCA jacks) inputs and outputs, as well as an LFE input. Instead of a volume control knob, the DSW Pro 400 has volume up/down buttons. The 30-pound sub measures 14.6 x 13.75 x 13.75 inches (HWD) when in the down-firing position.

We used the DSW Pro 400 with the Polk Audio RM95 speaker package. The satellite and subwoofer blend was less than perfect, so we could hear the DSW Pro 400 separate from the speakers, which isn't a good thing. That's not a slight against the DSW Pro 400, but rather an indication that the RM95 speakers don't produce enough bass on their own.

The DSW Pro 400's bass on movies and music was impressively deep and well defined. Even massive bass demands on Blu-ray discs like Master and Commander didn't overtax it. We took advantage of the remote to tweak the volume to just the right level every time we changed discs.

The DSW Pro 400 goes for about $360, with its 10-inch and 12-inch siblings retailing for $450 and $540, respectively. (The larger drivers in both should deliver more low-end oomph.) It's got just enough bells and whistles to justify the extra cost versus the 8-inch PSW111 (available for as low as $270), and it also outclasses the budget 10-inch PSW10 model. All in all, it's a very good subwoofer for the money.
