Commentary
A subwoofer with a built-in power amplifier.
The unit is equipped with a 20 cm cone type woofer and adopts SAW system to reproduce ultra-low sound more realistically.
In this system, a driving speaker unit is mounted between two cabinets in order to efficiently extract only the necessary low-frequency sound, so that the sound in the middle and low-frequency range is cut off with an acoustic filter, and high-quality heavy low-frequency reproduction is realized.
You can freely adjust the bass level and cutoff frequency.
In addition, it is equipped with a memory function that can store up to three patterns of settings.
The power amplifier section uses an R-core transformer, audio condenser, and audio diode to enhance sound quality.
Wireless remote control is included.
