The Ohm H was the very large bookshelf speaker most often used on the floor or short speaker stand.  It had very deep bass from the 8'' woofer and 12'' passive radiator.  It used two tweeters to reproduce the highs with an open, airy quality.  It was designed for medium sized rooms and delivered extremely extended frequency response.

The OHM H can have tighter and deeper bass with the addition of a SubBass Activator (SBA) with our upgraded 8'' woofer and new 12'' passive radiator.  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 has a self-resetting protection circuit.  The upgraded woofers have a new cone surround that is projected to last up to 30 years and the FerroFluid cooling handles the thermo transients from CDs.  The 12'' passive radiator's new foam surround is also projected to last up to 30 years.

Ohm allows up to $895 for the return of a complete pair of undamaged Ohm Hs toward 25% of the purchase price of new Ohm speakers.
