Subwoofer Drive Unit

Heavy weight long-throw motor design with

aluminium Faraday ring for reduced

distortion.

Magnetically shielded.

4-layer copper coil for high power capacity.

FEA

1

optimised coil and magnet design to

give a linear BL profile

2

.

Rear suspension and surround are FEA

optimised to give maximum linear excursion,

resulting in reduced distortion.

Auxiliary Bass Radiator (ABR)

Balanced, symmetrical, low profile ABR

design for more linear excursion and

reduced distortion.

Internally vented ABR air cavity resulting

in less compliance damping giving better

LF performance.

1

FEA = Finite Element Analysis - a design process where individual elements are computer modelled.

2

BL profile = measurement of the motor force factor on the speaker driver over the working displacement of the magnetic coil.

3

Opto-coupled LED and light sensitive resistor senses overdrive and automatically limits this to prevent damage to the unit.

Electronics

Highly efficient 250W class D

amplifier.

Thermal and overcurrent

protection built into the

amp and power supply

unit ensuring ultra reliable

performance.

Sophisticated limiter system to

prevent voltage overload,

optimised for maximum

audio quality
