If there is very little sound and it is scratchy, buzzy, or it rattles in the low frequency range, then a low repair is necessary. We must receive both speakers from you so that we can match them both to the good one.

When the system is very dull sounding but most of the sound is acceptable, it usually indicates that a high repair is necessary. Sometimes this is only noticed when one speaker is compared to another. We must receive both of your drivers so that we can match them both to the good one.

The metal can is the protective cover enclosing the driver. This should not be removed except at the Ohm factory. If third-party repairs are attempted, the final repair cost will be higher to fix whatever additional damage is done. However, a small cosmetic dent in the area opposite the wires will have no effect on the sound. These are sold and installed only at the factory after the drivers have been tested and found to be working properly.

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. Now they are all black. The latest style uses wood and perforated metal like the thousand series. The new ones also have no seams. They are much nicer looking than the originals.

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.
