The Ohm C+ replaced the Ohm C. It used the same 10'' acoustic suspension woofer and 1'' dome tweeter plus an added low tweeter to increase the power handling of the whole system. The sound quality remained and the system could use much larger amplifiers.
Upgrade Options:
The OHM C+ can have tighter and deeper bass with the addition of a SubBass Activator (SBA) and our upgraded 10'' woofer. The SBA eliminates the drive below the speaker's natural response to reduce distortion and clean up the deep bass. This allows for lower distortion, higher output and deeper bass, plus uses a self-resetting protection circuit. The upgraded woofers have a new cone surround that is projected to last up to 30 years, while FerroFluid cooling handles the thermo transients from CDs.
Trade-In Options:
Ohm allows up to $500 for the return of a complete
undamaged pair of Ohm C+s toward the purchase price of new Ohm
speakers.
