When I first heard H-PAS (Hybrid Pressure Acceleration System) technology from Solus/Clements and Atlantic Technology at CEDIA two years ago, I was very impressed at the depth of bass produced by relatively small drivers in a specially ported cabinet. Since then, we've reviewed the AT-1 floorstanding speaker, which garnered a Top Pick designation. At CEDIA this week, Atlantic Technology will be demonstrating its new H-PAS PowerBar 235, a 2-channel, 42-inch soundbar that claims to reach down to 47Hz at -3dB with no subwoofer. Can't wait to hear it!
