The Beta 20 will need the assistance of a subwoofer in all but the most intimate home theaters, so we used Infinity's CSW-10 sub. That said, we're pretty sure that Infinity's PS-10 or PS-12 will also provide stellar low-end support.
We tested the Beta 20 for use as both front and surround speakers. We enjoyed the speakers in our home theater with the Spider-Man DVD, especially when the 20s dished out knock-em, sock-em power on the early wrestling scene. The Betas' dynamic punch was excellent and can easily fill midsize home theaters with sound. Listening to CDs, we felt the new tweeter's enhanced clarity made for a more detailed sound.
