Want to make your sub disappear? Pinnacle's SCI M Sub ($600) is compact enough to fit behind a sofa. It can also work on-wall. Look for it in 2009 for $550. The external amp is $450. Pinnacle is also adding a new S-FIT line to supplement the existing Black Diamond line. In lieu of the latter's gloss enclosures, it has a simple woodgrain-like vinyl wrap with some nice build-quality details like metal grille pins. Models include floorstanding for $998/pair, monitor for $315/pair, LCR for $190/each, satellite for $115/each, and center for $265/each.
