The Accuton C220-11-221 Bass / Midrange is an esoteric 8.5 inch drive unit primarily intended for high end 2 and 3 way floor standing designs. The 11 ohm impedance makes this unit ideal for low powered valve amplification or for parallel connection.
This exotic driver features a ceramic (Sapphire) cone, soft rubber surround, large ferrite magnet and 38mm titanium coil former.
The spider, pole and voice coil former are fully ventilated for minimal compression. This unit has a substantial power rating of 150 watts and offers good midrange resolution / extension for a driver of this size.
