The woofer is generally the largest driver in the system which covers the bass and mid-range frequency.

High Tweeter

The high tweeter is generally the smallest driver in the system which covers the highest frequencies.


The crossover is the electrical circuit that protects the tweeters from the low frequency energy that is reproduced by the main drivers. This can only fail, in rare instances, from overdriving the speakers.

The Ohm J was a small speaker with super bass and extended highs from the same 1” tweeter used in Ohm’s more expensive conventional speakers. It offered lower sensitivity and limited use to smaller rooms and had amazing performance!

The OHM J can have tighter and deeper bass with the addition of a SubBass Activator (SBA) and our upgraded 6 1/2'' 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 and FerroFluid cooling which handles the thermo transients from CDs.

Note: Most Ohm upgrades require no specialized knowledge and are easily completed completed by any person. It takes less time to install your own upgrade than it does to package and return ship your speakers to the factory, therefore, we recommend you save time and money by doing this yourself. We ship the upgrade to your door with clear, easy instructions. If for any reason you prefer to have the factory complete your upgrade installation, we will be happy to do this for free, however, you will be responsible for shipping and handling costs each way.

Ohm allows up to $295 for the return of a complete pair of undamaged Ohm J's toward 25% of the purchase price of new Ohm speakers.
