产品参数：

HF Unit：Doped fabric diaphragm.  Central clamp and phase corrector.  Metal chassis, directly interfaced with Reference One alloy plate baffle for low vibration.  Shielded neodymium cup magnet system.  Low fundamental resonance for lowest coloration and improved linearity

Bass Mid Unit：100mm diameter, magnesium die cast chassis.  Open low reflection frame design.  High performance closed field neodymium magnet system.  Low stray field.  Vented rear suspension.  Air pumped cooling.  Low loss outer suspension.  Non-conductive glass fibre voice coil former.  Precision 32mm power voice coil.  105mm Pure Piston hyperbolic aluminium alloy cone, depth anodised to traditional AE practice.
 
Crossover：Delivers octave by octave equilisation for maximum monitor grade tonal accuracy.

3rd order acoustic, phase corrected;  drivers are wired in phase electrically.  Crossover elements 11, close tolerance components [+/-2% typical].

Vibration inhibited platform, low colouration power film resistors on alumina substrate.  Selected high current audiophile grade laminated core low loss inductors plus air core for high frequency section.  Selected audiophile grade polypropylene capacitors.
