Commentary
An active super-woofer system with excellent space factor and tuned to match any type of speaker.
The unit uses a cone-shaped woofer with a 1 mm thick delta-olefin reinforced diaphragm.
A thick diaphragm provides strength and confidentiality, and a maximum stroke of 33 mm is achieved by the engineering elastomer edge on the nerve with a raised part and double damper structure.
The enclosure is a floor type with excellent space factor.
The internal structure of this enclosure employs a newly developed tapered slit duct structure that continuously changes the effective length of the duct to prevent natural mechanical and acoustic vibrations, and is tuned to a special unit.
In the SL-10, a large slit duct with an equivalent diameter of 10 cm is installed on the bottom and the reproduced sound is radiated from the opening at the lower front. Therefore, it becomes a kind of acoustic filter and reduces wind noise and harmonics.
The filter position is 3-stage, and the cut-off filter is set to 24dB/oct. for combination with any speaker.
Equipped with a power amplifier with a built-in limiter of 70W.
Anti-magnetic design is applied to support AV.
You can choose between two types of connection : the high-level output terminal (speaker terminal connection) or the low-level input terminal (pin input) for the preamplifier output.
It comes with a remote controller and can adjust the level, output ON/OFF, and change the phase polarity.
Examples of connections are Filter Mid (55 Hz) on the D-200II, Filter Low (45 Hz) on the D-77XD, and Filter Low (45 Hz) on the Monitor2001.
