While Procella did not have any new product to show at CEDIA 2010, it did demonstrate a concept it had talked about before: the first THX-certified screening room. Designed and constructed to THX specs by Epic Home Cinema, it featured products from Runco, Integra, QSC, Meridian, and Stewart. More details here. Played at THX reference level, the sound was loud enough to shave ear hairs at a thousand paces, with especially tuneful and delicious bass, something almost unheard of at a trade show. Chuck Back was kind enough to pose for a scale pic of the P18 sub but blinked while our auto-focus was taking its time. Apologies.

Atlantic Technology uses cabinet-related techniques developed in collaboration with designer Phil Clements to achieve truly scary deep bass response from small cabinets and 5.25-inch woofers. This H-PAS technology was a highlight of the last CEDIA. At this year's show the floorstanding Model AT-1 ($2500/pair, shipping now) has been joined by the stand-mount Model AT-2 ($1500/pair, shipping February). The demo seemingly defied the laws of physics, achieving the kind of bass you'd expect from a decent midpriced subwoofer, except without the sub. Without even a floorstanding enclosure. We wouldn't have believed it if we hadn't heard it.

Martin Logan's new Motion Series is a downsized line of towers with folded motion ribbon tweeter, shown. Both this smaller Motion and the existing larger Motion have complementary center and surround models. The company also showed the new ESL tower, which offers its famed electrostatic goodness at less than $2000/pair.

Two subs in Paradigm's Signature Series have hexagonal enclosures to defeat bass-polluting vibration with six drivers inside. The SUB 1 has 1700 watts and sells for $4499. The SUB 2 has 4500 watts, sells for $8999, and will be a limited production run, so act fast if you want it. Of course all the brawn in the world still won't provide tuneful bass if your room's standing wave is muddying the waters -- but these elite subs use Paradigm's Perfect Bass Kit to measure the room and apply appropriate correction.
