The VEX-8 was designed to handle an enormous 300-watts RMS thanks to its generous 2.5” coil (with a full 20mm winding length) and highly efficient airflow system consisting of twelve gaps vents and a chamfered, large-diameter pole vent.
The long coil also affords the VEX-8 a full 9mm of linear x-max one-way so it can play lower than many other high-efficiency drivers without distortion. The inductance is kept in check by a dual shorting-ring system (magnet ID & pole cap) which drops the LE spec to less than 25% of the RE value. This allows the high-frequency extension to reach all the way up to 5,000 Hz where it then falls of naturally and smoothly on its own thanks to the extremely strong and non-resonant carbon-fiber cone & dust-cap assembly.
Most high-efficiency drivers utilize very light-weight paper which is great for sensitivity but not so great in terms of breakup modes and strength (to withstand torture in bass-heavy vehicles). The whole package is held together with a sturdy cast-aluminum frame that features extensive spider cavity venting to further increase thermal power handling.
