The Fisher XP-55 speakers

Compact Free-Piston Speaker System

Though it measures only 20" by 10" by 9" deep, the Fisher XP-55 incorporates a bass speaker that is very close to that of large speakers and at the same time free of artificial correctives like shaping networks that after the bass output of the amplifier.

This is an 8-inch unit with a magnet structure weighing 3 pounds, a flux density of 12,500 gauss and a totally new suspension system utilizing a long-throw jnverted half-roll surround. Free-air resonance is 33 Hz, an almost incredible figure for an 8" driver. The 2-1/2 inch tweeter has a new low-mass cone made of a combination of the usual fibrous materials resulting in peak-free response out to 19,000 Hz without coloration.

The completely enclosed baffle is heavily damped with Acoustiglas packing. The result is fundamental bass response down to 37 Hz, without doubling.
