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. FEA1 optimised coil and magnet design to give a linear BL profile2
- Rear suspension and surround are FEA optimised to give maximum linear excursion resulting in reduced distortion
Electronics
- Highly efficient 250W class D amplifier
- Improved electronic circuitry makes the bass sound brighter, faster and more dynamic
- 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 quality3
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.
