Beryllium dome for non-resonant high frequency extension. Two part aluminium faceplate with integrated mechanical decoupling. Dual balanced compression chambers for improved dynamics. Dual copper caps for absolute minimum voice coil inductance and minimum phase shift. High saturation neodymium motor system with T-shaped pole piece for lower distortion. Non-reflective cast aluminium chamber with optimized damping for improved dynamics. Shallow flow optimized magnet structure for optimum coupling to rear chamber. CCAW voice coil for low moving mass. Long life silver lead wires. Low resonance frequency for extended range.
