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 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 affect on the sound. These are only sold and installed 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.

This upgrade exchanges the complete driver and input board, plus adds a new vent adapter. You benefit with deeper bass, higher output and extended highs with wider dispersion.

The original surrounds typically last 10 to 20 years while our new surrounds are projected to last up to 30 years. They give you better transition to the mid-range for smoother vocals. At the same time, we change the old dampening material on the inverted driver and re-balance the pair to ensure that they are properly matched and performing correctly.
