Using the 4-fold DIP switch
several important parameters can easily be altered.

The low pass filter can be switched from normal-mode to infra-mode, to reduce frequencies above 65Hz.

Additionally, the limiter can be switched to a 2dB lower threshold, just to be on the safe side when your gigs tend to get out of control...

And of course this sub also has DIP-switches to reduce the input sensitivity with 3, 6, or 9dB.





D-Sub2, designed for bass reproduction in conjunction with a D-Top2, uses two very high performance 18 inch subwoofers with highly improved voice coil cooling, thus raising long term power and reducing thermal compression to a mere 3 dB.

The computer designed enclosure increases speaker load dramatically, increasing acoustic efficiency, and substantially reducing cone excursion.

A state of the art switching amplifier provides massive power at about 95% efficiency. This means an energy loss of only 100 watts at 2000 watts mains input. Advantages: No thermal problems, superb mains efficiency. Only 6A mains current draw @ max power. (=averaged musical program value, short bursts may show conciderably higher values) This means a complete Control system may be driven to max power on only a 16 ampere /230V mains supply.

Newly developed smart processing ensures safe operating conditions for the drivers. Additionally, level dependant Fletcher Munson compensating bass processing is performed to achieve best performance at all sound levels.
