The B2 subwoofer was the subwoofer section of the B2 without the woofer and tweeter. It had a special version of the 12'' subwoofer with dual voice-coils so two channels of amplification could drive it.
Upgrade Options:
The upgrade option available for the
OHM B2-Subwoof is the addition of dual SubBass Activators, which eliminate 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.
Trade-In Options:
Ohm allows up to $595 for the return of a complete pair of undamaged Ohm B2-Subwoofs toward 25% of the purchase price of new Ohm speakers.
