The Klipsch R-20B is no longer available as of early 2018. Check out the current product review for information on recent models.
If booming bass is what you're after, the Klipsch R-20B is the soundbar for you. It's external subwoofer produced the deepest, most resonant bass we heard in our testing. It also produced good treble. Its overall sound wasn't quite as good as the top scoring Sonos Playbar, but it was close. Combine that with a nice design and good user interface, and you've got an excellent soundbar for those that tend to judge sound quality based on the low end. So let your bassophile flag fly and get blown away by the power of the Klipsch R-20B.
