New techology includes a FRONT. unique deep copper-sleeved gap low-distortion motor structure topology, coupled to Vented Gap Cooling (VGCTM>l,delivering accurate reproduction at high power HORIZONTAL. levels with minimal power compression. Harmonic dis- tortion is effectively minimized through the use of dual shorting rings. An aluminum ring stabilizes flux modula- tion to reduce second harmonics, and a copper ring cen- tered in the voice coil gap virtually eliminates third har- monic distortion. To improve both waveform accuracy and dynamic linearity the motor and voice coil were carefully engineered. A 100 mm (4 in) diameter voice coil, 16 mm ( in) long is positioned in a deep gap to provide accurate motion to excursion extremes.))

This increases acoustic LEFT RIGHT. -r output, and linear dynamic range. Convection cooling is 0. accomplished by encasing the black, neodymium magnet assembly in a diecast aluminum frame designed as an effective heatsink. Dynamic range is increased by as much as 6 dB over competitive transducers.
