Infinity, JBL, and Revel Follow a Train of Thought

The Infinity ERS 610 in-ceiling speaker ($599, October) features a flat diaphragm CMMD woofer similar to that in the high-end and somewhat revolutionary Cascade series. JBL and Revel offer very similar-looking products (under the great Harman International corporate umbrella, of course). The hot one might be the Revel, since it's been voiced by Kevin Voecks. Note the three-position switch at right, which adjusts high-frequency response for the room. Not pictured are the wireless 2.4GHz subs, the 10-inch PSW310W (10 inches, 400 watts) and PSW212W (12 inches, $679, January).
