A200

5.5” Aluminium cone low distortion mid-woofer

The 5.5" woofer in the A200 is an aluminium cone/large voice coil signature' Phil Jones design. It uses a neodymium motor to provide high magnetic flux to cover the entire voice coil of the loudspeaker. This is rarely done in speaker construction because of the sheer cost. The majority of loudspeakers uses a voice-coil mostly overhung outside the magnetic field . By using a much larger magnetic field in the A200 woofer, we considerably reduce harmonic and inter-modulation distortion, giving the speaker a more musical and natural sound. The proprietary aluminium alloy cone was designed from thorough analysis of all types of cone geometry and materials using a Klippel Laser Doppler Interferometer, a scientific precision measuring instrument that analyses cone behaviour in 3D environments. The voice coil in A200 woofer is unconventionally larger than most 5.5" loudspeakers. Larger voice coils have less power compression because they run at a cooler operating temperature. Sonically this means a more realistic dynamic representation of the music. It is dynamics in music that gives it emotion and exhilaration. The cooler running temperature of the voice coil also brings a benefit of reliability and extremely rare driver failure. Most loudspeakers use round copper wire in the voice coil. The A200 uses a far better single layer edge-wound copper clad aluminum ribbon. Ribbon voice-coil wire gives more electrical conductor in the magnet gap and increases efficiency, power handling and lowers distortion. For optimum performance without compromise, the A200 woofer uses a hyper-rigid cast-magnesium alloy frame. Its increased rigidity greatly reduces speaker coloration, and its material helps to dissipate heat efficiently from the voice coil much faster than a typical steel speaker frame, all of which lead to increased dynamics and power handling and ultimately, a much more satisfying musical experience.
