C90-6-724
The C90-6-724 is a 5 inch chassis (124mm) Midrange / Bass drive unit with an ultra hard ceramic (Sapphire) diaphragm in the form of a large inverted dome.
The voice coil former is the same diameter as the dome and is bonded to its outer periphery - the entire rear radiating surface is completely unobstructed and free from the effects of reflection or unwanted stored energy.
This unit features a low loss rubber surround and a strong but delicate fabric spider giving an impressive maximum linear excursion of 8mm.
A very discrete and secure clamping technique provides easy mounting and adaptation to individual baffles.
We recommend an application from 60 Hz – 6000 Hz.
