The Accuton C173-6-191 Bass / Midrange is an esoteric 7 inch drive unit primarily intended for high end compact bookshelf monitors and slim floorstanding designs. Developed from the C173-6-095 this unit features a high but narrow profile surround resulting in an improved maximum excursion of 10mm - good SPLs from compact enclosures.

This state of the art driver features a ceramic cone, soft rubber surround and a powerful motor system. The 38mm ultra lightweight titanium voice coil former ensures good midrange resolution.

The spider, pole and voice coil former are fully ventilated for minimal compression. This 6 ohm unit has a power rating of 120 watts .
