Everything sounds better with Sub.

http://gregorydowling.com/my-walk-across-desolate-venice/?replytocom=1220 When you pair a Sub with any Sonos speaker, you’ll hear parts of your music that you wouldn’t hear otherwise. Sub does all the heavy lifting required to deliver the low, low frequencies, letting your other speakers focus on perfecting the mid and high-range frequencies. You won’t just hear the difference. You’ll feel it.
