FRS stands for Full Room Stereo, which delivers a firm detailed stereo image spreading from one speaker to the other with each performer in the right place always heard from a very wide Sweet-Sweep.
The FRS 5 was the 12'' cube with the tweeter on one corner. It was for small rooms. It had a vent loaded 6.5'' woofer to match the 5/8'' super-tweeter.
Upgrade Options:
The upgrade available for the OHM FRS-5 is the addition of the SubBass Activator, which eliminates the drive below the speakers 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.
Trade-In Options:
Ohm allows up to $495 for the return of a complete pair of undamaged FRS-5s toward 25% of the purchase price of new Ohm speakers.
