What We Don't Like

Polk Audio delivers great performance in the subwoofer department across their line-up. Low to high, every one of their woofers is tuned with the Klippel distortion analyzer, delivering excellent performance. However, the DSWPRO 660wi adds an extensive set of features, making it one of the best options under $500.


The design of this subwoofer is one of the most unique I have seen. The box is pretty run of the mill upon first glance, finished in a slightly matted black throughout with curved edges, and Polk branding in the front. However, the four rubber feet on the bottom can be detached and moved to the back side of the subwoofer, giving you the choice between a bottom firing or front firing woofer.

From an aesthetic standpoint, I really do love the look of the 660wi. The finish is beautiful, the lines are clean, the feet don’t distract, and the overall look of the subwoofer feels high-end. However, the practical winner is design is with the customization granted from the moveable feet. This design not only allows you to tweak the look of the subwoofer, but also the sound which is big in the way of innovation and flexibility.


This subwoofer really hits it out of the park in terms of it’s feature set, though. Starting from the top, the speaker can be operated completely wirelessly via an included remote. On that remote, there’s controls for power, volume, mute, phase (in 0, 90, 180, and 270 degrees) LED switch, and reset. Also included are four presets for the built-in Polk Room Optimizer. This gives a quick switch to optimize the subwoofer for it’s placement in the room, delivering optimal performance given the surroundings. There’s also a handy night mode that turns down the subwoofers intensity for, well, night time.

I am beyond satisfied with the very generous feature-set included here. Remote functionality makes using the speaker a breeze overall, not having to reach back to tweak a few settings. My favorite of these settings was in the night mode, honestly. Countless times I have sat trying to find a perfect balance between my sub and speakers at night, and this quick switch solves my problems in a single button.


However, not everything is peachy with this subwoofer. While the feature set is much more extensive, don’t expect performance to be a significant upgrade from more inexpensive models in Polk’s line. The sound is good, with tight and consistent bass, but not as high of quality as I was expecting out of a speaker at this price point. Also, the IR remote had some issues communicating with the speaker which posed an occasional problem.

Now, that isn’t to say that this subwoofer is a poor performer because it certainly is not. The subwoofer sounds very good and will satisfy most users. However, the performance takes a backseat to the included features, making the price not seem justified when considering the raw sound alone.

The Rumble:

The Polk Audio DSWPRO 660wi is a fully packed subwoofer that delivers decent performance overall. The innovative and attractive design compliment the extensive feature set, only slightly muddied by good, but subpar, performance.
