Magnepan is well aware that the problem most people have with their speakers is their frontal area. The 30.7 is a dedicated audiophile speaker. Very few women are going to let them into any room they expect to have company in. Setting up the 30.7's high frequency panel with subwoofers is a brilliant idea. Notice the plural in that statement. The high frequency panel of the 30.7 is a line source throughout it's range. It would overwhelm a single subwoofer. To do it right the subwoofer would have to act as a line source so that it projects power as well as the panel. This can be done with a floor to ceiling subwoofer array negating the purpose of this experiment or a wall to wall subwoofer array using 3 to 4 individual drivers. I would use 4 drivers in two cabinets. 2 12 inch drivers mounted in the ends of a 14" tube about 4 feet in length. A balanced force design.
These would be placed horizontally at the front wall floor border about 1 foot from the room corners. In black the subwoofers would disappear visually leaving only the thin high frequency panels. With the right crossover and amplifiers this would work extraordinarily well, maybe even better than with the bass panel.
Wendell, I have a system based on the old Acoustat 2+2's, a floor to ceiling dipolar radiator similar to the 30.7's just ESL. I use a more basic subwoofer system using 4 separate drivers spread along the front wall. Everyone who has heard it thinks the results are excellent. I also cross up at 125 Hz which is unusual in the subwoofer world. I can not hear the crossover at all.
