Polk Audio Command Bar soundbar review: Good sound, with Alexa at your service

To answer the question posed in the subhed, no, Polk didn't create the Command Bar by taking a hole saw to the middle of its chassis and dropping an Amazon Echo Dot in there. But the feature is unquestionably designed to look like that, and this soundbar does support Amazon's Alexa digital assistant. Soundbars are hot these days, and they run the gamut from sub-$100 cheapies to the ludicrously priced, but wow-it's-impressive Creative X-Fi Sonic Carrier. Polk is going after the better-than-entry-level market with this $300 speaker. That makes it $100 cheaper than the recently reviewed Sonos Beam, and it comes with a nicely matched subwoofer.
