7 inch Ceramic Bass / Midrange driver with damped cone.
The Accuton C173-6-191E Bass / Midrange is an esoteric 7 inch unit primarily intended for small floorstanders and bookshelf monitors.
Developed from the C173-6-095E, this drive unit features precision cut apertures in the diaphragm which critically damp the 4kHz cone resonance resulting in a much smoother midrange performance as can be seen on the downloadable datasheet. The maximum excursion of 10mm ensures good SPLs from small cabinets.
This state of the art driver features a ceramic cone with soft rubber surround and an impressive motor system comprising a very large ferrite magnet and 38mm titanium voice coil former. The spider, pole piece and coil former are fully ventilated for minimal compression. This 6 ohm unit has a power rating of 120 watts .
