D 8SUB
Subwoofer
The D 8SUB matches the D 8 series beautifully, both sonically and design-wise. A very discreet design, with real wood corners and an elegant glass top, hides a very powerful subwoofer – a monster in disguise…
The D 8SUB subwoofer features a 12in active woofer and a 12in passive radiator to portray depth. The 400 watt class D amplifier in D 8SUB is a SMD (Surface Mounted Devices) technology piece.
Auto On/Off
Forget all about the subwoofer once it is connected as this feature automatically switches the subwoofer on when it receives an input signal and sets it in stand-by after approximately 20 minutes without input signal.
Class D digital amplifier
The power is delivered by a class D digital amplifier, chosen because it is much more efficient than conventional amplifiers - it simply produces more sound and less heat. And with lower power consumption the need for cooling is significantly reduced which again reduces the size of the heat sinks. Also the circuitry layout itself is more compact which besides space savings also grants shortest possible signals paths and thus optimum sound quality. A digital amplifier is not a cheap solution, but it is the right solution in order to decrease the size and enhance the performance.
Passive radiator
When employing a passive radiator or a bass reflex vent, the bass response is extended downwards compared to a closed box. The advantage of the passive radiator is that port noise is eliminated and that the excursions of the woofer itself is reduced at the lowest frequencies i.e. less strain on the drive unit, and less power needed to reproduce the sound.
Level-, Phase- and Cut-off controls
Continuously variable level, phase and cut-off frequency controls make it easy to tune the subwoofer to suit virtually any speaker on the market as well as different placements and personal preferences.
