SONY APM-22ES

Commentary

A 2-way speaker system that employs an APM unit.

290 cm for the lower range²Uses APM type woofer.
The aluminum honeycomb vibration plate is driven at multiple points by four armatures directly connected to the voice coil, and the divided vibration is effectively canceled to expand the pistic motion band.

16 cm for the high range²APM type tweeter has been adopted.
A light and strong aluminum honeycomb vibrating plate is driven by a large voice coil at the point where the milestones of divided vibration concentrate, eliminating divided vibration within the audible band.

The level of the tweeter can be controlled from 0 dB to -50dB.

In order to prevent the diffraction phenomenon in which sound waves are reflected at the corners, the enclosure uses an acoustic rounded enclosure with R at four corners.
Also, there are 2 types of finish, black wood-grain and walnut.

There was a speaker stand sold separately.
