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 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 development process where individual components are modelled and analysed within a
computer program.
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 is
optimised for maximum
audio quality
