More and more customers require high output subwoofers for their home cinema. This is an extremely solid subwoofer with high output.

The bass drivers used in the Sub 25 are the extremely solid Newtronics Sub 15. They comprise:

  • an extremely solid die cast basket
  • double ventilated voice coil
  • an extremely wide surround with 40 mm
  • a drive system adequate for low bass
  • an impedance of 4 Ohm, ideal for exploiting the amplifier's capabilities
  • gold plated terminals

    • Located on the rear side of the subwoofer is the amplifier module RCM Detonation DT 500. This module features state-of-the-art technology, in order to produce an enormous output with top quality coming from a small cabinet.
