For those craving just a little more bass -- or, let's face it, bragging rights -- than afforded by the 10-inch ASW 10 CM subwoofer, Bowers and Wilkins has gone ahead and added the ASW 12 CM. Guess what? It's a 12-inch model. Going along with the B&W calling card of a cone with Kevlar, the ASW 12 CM adds a 500-Watt switching amp and a three-way switch for selecting between the 18, 23 and 28-Hz low frequency cutoffs. Insecure audiophiles may never consider dialing things back from the 18-Hz rating they paid $2,000 for, but sensible folk will heed our advice -- if your room can't handle really low bass, don't even try to make it work; definitely go for bass quality and not just quantity. B&W agrees, and has added controls for low-pass frequency, roll-off alignment, and phase so you can tweak to your ears' content.
