Earlier this year, my home was infested with smart speakers—I've used a lot of them at this point. But I’ve never used an Alexa device as dedicated to the cause as the Polk Command Bar, a soundbar that wants to be an Amazon Echo so badly that it’s practically in cosplay. It’s designed to look like engineers smushed an Amazon Echo Dot right into the center of it. In many ways, that's precisely what Polk did.
