ALLISON Six

SIX

Allison Six Loudspeaker
Conception:
1975

In the Allison Six ("Le Cube"), the Stabilized Radiation Loading design principle is carried to just about its practical limit for an 8-inch woofer. The cabinet is reduced in size to 1/2 cubic foot, yet the system's low frequency output is basicaly flat to below 50 Hz (-3dB at 46.5 Hz) while maintaining reasonable efficiency. 

The same Convex Diaphragm tweeter as those used in all Allison loudspeaker systems is also used in the model Six. Therefore it has the equivalent high-frequency range, smoothness, and wide dispersion in the foward hemisphere.
