The woofer is generally the largest driver in the system which covers the bass and mid-range frequency.
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 B2 was the most sensitive speaker Ohm ever produced. It was basically a 2-way 6.5” woofer and a 1” dome tweeter combined with a built in 12” sub-woofer. With the woofer firing toward the ceiling and the tweeter into the room, is was an early effort at controlled dispersion. The bass and mid-range were fully omnidirectional while the treble fired away from the walls and made placement much easier than a fully omnidirectional speaker.
We have an improved 6.5'' woofer with a poly-cone for a smoother transition to the tweeter. A SubBass Activator can also be added to the sub-woofer to extend the bass, reduce the distortion and increase the dynamic range, plus uses a self-resetting protection circuit. The high tweeter is now a smaller dome for wider dispersion.
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 $1000 for the return of a complete undamaged pair of Ohm B2s toward 25% of the purchase price of new Ohm speakers.
