Long Throw Ceramic Bass - Midrange. 6.25 inch / 158mm chassis.
The Accuton C158-6-851 Bass / Midrange drive unit features an ultra hard ceramic (Sapphire) 120mm cone inside a 158mm diameter chassis.
Designed specifically for small monitors and slim floor standing designs, this esoteric unit has a soft rubber suspension and a large 10mm max. excursion allowing it to produce very good volume levels from small footprint enclosures.
A high power pure copper voice coil and ventilated titanium voice coil former yield a substantial power rating of 120 watts - quite high for a domestic driver of these dimensions.
