Accuton C158-8-085 Ceramic Bass / Midrange

6.25 inch / 158mm Ceramic Bass - Midrange. High midrange resolution design.

The Accuton C158-8-085 Bass / Midrange driver is a development of the  C158-6-851 with a slightly different design criteria : a revised motor system comprising of a light weight 25mm voice coil and titanium former assembly give improvements to both midrange resolution and extension plus a mild increase in sensitivity.

Designed specifically for small monitors and slim floor standing designs, this esoteric unit has a soft rubber suspension, an ultra hard 120mm ceramic (Sapphire) cone and a large 10mm maximum excursion allowing it to produce impressive volume levels from small footprint enclosures.

The spider, pole and voice coil former are fully ventilated for minimal compression. This 8 ohm unit has a power rating of 100 watts - very respectable for a domestic driver of this size.
