D-Sub3 is a high SPL subwoofer, designed especially to keep up with our D-Top1.
With its height of 1,50m, this sub is just the right height for stacking the D-Top1.
These two units don't only match perfectly in performance, but also logistically; pull the sub backwards onto its wheels, lay down the top on the subs front, and a complete one side PA-stack is rolling in or out the venue!
The D-Sub3 incorporates three ultra modern neodymium woofers. These woofers are built using the latest techniques:
Double, optimised voice coil cooling reducing thermal compression tot a mere 3 dB, and neodymium magnet assemblies for a very high magnetic flux and yet low weight.

These woofers all have their own large enclosure and porttuning in the D-Sub3.

A state of the art switching amplifier provides massive power at about 95% efficiency. This means an energy loss of only 225 watts at 4500 watts mains input. Advantages: No thermal problems, superb mains efficiency. Only 12A mains current draw @ max power. (=averaged value playing musical program, short bursts may show conciderably higher values) This means a complete D-sub/D-Top system may almost be driven to max power on a 25 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.
