The woofer is generally the largest driver in the system which covers the bass and mid-range frequency.
The SubBass Activator is an electrical circuit which extends the deepest bass when the music calls for it, reduces the distortion for cleaner sound, increases the dynamic range for greater impact, and uses a self-resetting protection circuit to reduce the chance of damaging the speakers.
The grill is the cloth and frame used to cosmetically conceal the drivers without affecting the sound. Ohm now uses black grills in almost all cases. In the past, brown and brown/black mixes were used; but every ”brown” turned out differently. Now they are all black (except on some current white speakers, we have white as an option).
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 passive radiator looks like a large woofer from the outside. It produces the deepest octave of sound and has no magnet or motor assembly. The air inside the cabinet acts like a spring with the woofer driving one end and the passive radiator (PR) at the other. At the low frequency where the spring and the PR resonate, extra energy comes out of the system. Typically, the foam edge deteriorates within 20 years. We now use a new foam edge that is projected to last up to 30 years.

The N was the first sub-woofer to go with the Ohm Ms. It used an 8” woofer and 12” passive radiator for each channel in one walnut veneered cabinet. The 3-piece system sounded like a pair of Ohm H’s.
One upgrade option available for the OHM N 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.
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 $400 for the return of each undamaged Ohm N toward 25% of the purchase price of new Ohm speakers.
