Commentary
A tower-type SAW sub-woofer that is easy to install.
The unit is equipped with a 16 cm cone type woofer and adopts the SAW system to reproduce the heavy low sound with good sharpness.
The SAW (Super Acoustic-Loaded Woofer) system has a structure in which a driving speaker unit is mounted on a sub-baffle plate installed in the cabinet. It extracts the necessary low-range playback sound from the duct, and at the same time, it has the characteristics of cutting out the sound above the middle and low frequencies with an acoustic filter, making it possible to effectively play back the heavy low frequencies.
In the SAW system, the load is applied symmetrically with respect to the movement of the diaphragm of the speaker unit in the front-rear direction, so the drive with small amplitude and less distortion is realized.
Built-in 75W power amplifier for unit drive.
It is equipped with a low-boost switch and a phase-change-over switch to further emphasize the deep bass.
The cutoff frequency can also be adjusted.
Equipped with an auto power switch function that turns the power ON when an audio signal is input.
By adopting the MFB method, the bass reproduction capability is improved.
It comes with a wireless remote control for muting and level control.
