Subwoofer Technology
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.
Electronics
Highly
efficient
250W
class
D
amplifier.
Thermal
and
overcurrent
protection
built
into
the
amp
and
power
supply
unit ensuring ultra reliable
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.
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.
