Commentary
This is a speaker system that inherits the basic design of the APM-22ES and is compatible with AV.
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.
It has a magnetic shield and does not cause adverse effects such as color shift or color unevenness on the screen even if it is placed next to the television.
Equipped with a 2-position AV equalizer, the sound quality in the AV position is slightly reduced in the middle and high frequency range.
The pass position also provides a natural sound quality that conveys the quality of the digital source.
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.
There was a speaker stand sold separately.
