The Allison convex-diaphragm tweeter is functionally equivalent to a pulsating hemisphere, so dispersion at the highest frequenties is more uniform than that of any other tweeter. This design produces flat power output without on-axis beaming, precise stereo imaging over a large listening area, and an accurate simulation of the original space around the image. Allison technology reproduces sound that musicians and experienced concert-goers immediately recognize as being very close to the original.
The Allison 120 has the same robust, solid bass that Stereo Review called „astonishing” in the Allison models Four, Five and Seven. Middle and high frequencies have the transparency and openness that only the Allison tweeter can provide. We consider this system to be one of the best buys of all speakers now available.
