The 15″ and 18″ active subwoofers use a single Class D amplifier to drive the LF transducer.

Inside the Delta-AX subwoofers is a highly efficient Class D amplifier.

Using convection cooling, Delta-AX models do not use any internal fans. Fans add to product weight, ambient noise and can lead to unreliability. Delta-AX has no fans!

The amplifier has been perfectly matched to the custom low frequency driver. This perfect combination leads to maximum efficiency and supreme output SPL.
