Commentary
Active subwoofer with ultra low sound that matches the texture of medium to small size speakers such as D-500II and D-202.
The unit uses an 18 cm unit composed of a highly stable long-stroke suspension system and double dampers.
The duct section is equipped with a new type of duct that has succeeded in reducing wind noise and harmonics.
A 60W power amplifier with a built-in limiter is installed to provide a stable power supply.
Equipped with a cut-off filter that can switch the cut-off frequency in 3 stages.
In addition, by setting it to 24dB/oct., fog and distortion in the middle and low range with the combined speakers are suppressed.
The input jacks support both speaker output and line output.
The design matches the wood-grain tone that is often seen in single speakers. In addition, smoke tempered glass is used to suppress resonance.
