YAMAHA YST-SW325

Commentary

325 series active subwoofer.

The unit is equipped with 20 cm cone type woofer.

QD-Bass technology is adopted.
In this system, the woofer unit is installed downward and a pyramidal diffuser plate is installed on the bottom to efficiently radiate low-temperature energy in four horizontal directions.
As a result, the frequency characteristics are smooth and free from peculiarities, and the setting can be done freely regardless of the installation location.

The enclosure uses the A-YST II system.
Based on the concept of an air woofer that uses air itself as a diaphragm, the A-YST system enables low-frequency playback equivalent to that of a large speaker even in a small enclosure.
The A-YST II system is a further development of this system. It drives the frequency band above the "fo" (lowest resonance frequency) of the woofer unit with constant current. It also adopts a unique shaped port that suppresses wind noise, further improving the sense of speed and clearness of the deep bass sound.

There are 2 color variations for finishing the exterior, cherry and black.

Equipped with a high-cut filter.
