DIATONE DS-301

Commentary

A four way speaker system that employs an acoustic air suspension system.

PW 3020, a 30 cm cone type woofer, is installed in the low range.
This unit uses specially pressed reinforced cone, alnico magnetic circuit and roll edge with excellent linearity to achieve excellent low sound reproduction.

The mid-range is equipped with DM-2210, a 5 cm dome type squaker, and the high-range is equipped with DH-2201, a 3 cm dome type tweeter.
By adopting a dome type, directivity is improved, and by installing an acoustic diffuser, orientation is improved.

A 3 cm cone type super tweeter using an ultra-light mass aluminum diaphragm is mounted in the ultra-high frequency range.

Equipped with continuously variable level control for each band from 1.5 kHz to 6 kHz and 6 kHz to 25 kHz.

The enclosure uses an acoustic air suspension system. Each unit is carefully patted to prevent air leakage. Transient characteristics and distortion in the low frequency range are improved. The enclosure is reinforced to a sufficient thickness to prevent box rumbling.

The exterior has a natural walnut finish and the front baffle is covered with black leather.
A double net is used for the front net.
