HKD $2000 per pair. Welcome to come view and test  
The active subWoofer which reproduces 20Hz - 90Hz super-low-pass one.  
SL-1 is an acoustic transformer using a 38cm monotonous type passive radiator and a 20cm driver, it has become a closed mold enclosure of the internal volume abbreviation 80L, and builds in the PWM scheme drive amplifier of 60W output.  
 
A 20cm cone type driver and a 38cm passive radiator are carried in the unit. The frequency characteristic near a bandpass property is maintained by using the light filter which consists of front cavities which combine it with these units, and a flat play is performed over the whole using band.  
 
The PWM (pulse duration modulation) scheme power amplifier of Output power 60W is built in.  
In SL-1, since the Oide power amplifier is structurally built in enclosure, special consideration is needed for an internal temperature rise. Compared with the amplifier of other schemes, the same output also has few power losses, and the PWM scheme is a scheme suitable for such a destination.
