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.
Low Tweeter

The low tweeter is generally the midsize driver in the system which covers the upper mid-range and low treble

High Tweeter Upgrade

This option upgrades the sound of the D2 to equal the performance of the more expensive C2, by adding the C2’s high tweeter. You’ll need a keyhole saw (not included).

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 D2 was the economy version of the popular C2. It used the same 10” woofer in a simpler cabinet and used the C2’s low tweeter, without the second tweeter. On axis, it sounded nearly the same; while off axis the C2s had more extended treble. An upgrade kit with the extra tweeters is available.

The OHM D2 can be upgraded to the sound quality of an OHM C2 with the addition of a dome tweeter and crossover harness. The upper treble response is extended to add sheen to cymbals and metallic quality to horns. To use this kit you must first cut a hole in the front panel (a template is provided) and then install the crossover harness.

Both the C2 and the D2 can have tighter and deeper bass with the addition of a SubBass Activator (SBA) and our upgraded 10'' 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, while the FerroFluid cooling 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 $595 for the return of a complete pair of undamaged Ohm D2s toward 25% of the purchase price of new Ohm speakers.
