Home High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

RE: Sorry- doesn't work that way.

Radiating efficiency does go up as the number of drivers is increased. However, the upper -3dB frequency goes down by a factor of 0.7 with each doubling of drivers, so the law of diminishing returns is in effect, and eventually you reach a maximum system efficiency of some 25% with direct radiators. This was long ago quantified by Don Keele in his AES preprint on the efficiency of moving coil drivers. Were this not the case with sufficient drivers you could exceed 100% efficiency, and then you wouldn't need a cold fusion reactor to provide the power for the system.
