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 system is upgraded with the driver from the Walsh 2000, new input terminals and adapter. This allows for deeper bass and wider dispersion of the high treble.

Kurt G. wrote to us and said, “Well, it has been 2 months since I upgraded my original 31 year old Walsh 2 speakers to the new Walsh 2000 drivers (the cabinet is the only part reused from the originals). So I now have a wonderful pair of Walsh 2.2000’s and all I can say is “WOW!”. Within the first ten seconds of listening to them, without exaggeration, my jaw literally dropped open at the gorgeous sound coming from my new speakers. And my appreciation of them has only grown in the last two months! I also have a pair of FRS11’s (1989) and a pair of Walsh Super 2’s (2007), and as good as these sound, the Walsh2.2000’s really are a BIG step forward. Thank You Mr. John Strohbeen and Ohm Acoustics - Good Listening indeed!”
