Bass Boost
Boosts bass output by around 10 dB/45 Hz in the amplifier.

Cooling Fan
Fan used to extract heat from amplifier case. Enables more compact case design, while constant low temperature ensures less interference and longer component life.

Distortion Reduced Motor Design
A special magnet construction practically eliminating distortion naturally caused by self-induction and impedance varying with excursion of the voice coil. This results in unbelievably clean bass reproduction.

High Level Input
Input used to connect a car radio directly to an amplifier if the radio is not equipped with a preamp out or line out.

High Definition Air Cored Inductors, Polypropylene Capacitors
High quality crossover components for excellent sound reproduction.

Maximum Power
Maximum power output by loudspeakers at pulse peaks.

B | C | D | H | M | N | R | S | T | V

Nomex/Kevlar/Glassfibre
Material used in high-tech applications from space travel to performance cars. Ultra stiff but relatively light, incredibly stable even at very large sound pressures. Offers improved accuracy and greater consistency over the frequency.
