Let's just say that one of my Ohm F's is terminated and another is limping along due to my local power company. I've been having bad problems with the AC lately and today was the topper.
In the last two months, my power has gone down at least a half dozen times. On two different occassions, the pole transformer on my street caught fire. Other times, the power simply blinked out and then came back on a short period of time later. This time, the power shut down and then popped back on about two minutes later.
As to how the F's were damaged, I was using a set of them as temporary fill-in's on my HT system. I don't normally have these speakers in this system, but i pulled my HT mains apart. I don't know if this was simply fate or bad timing for me to have them in this system, but what's done is done. Now i've got to try and clean up the mess.
What happened is that when the power came back on, the CD that was in my Denon 2900 began to play. Somehow, probably due to the voltage glitch, the volume was cranked WAY up on my Pre / Pro. Once the sound started, there was a horrendous amount of racket coming from one speaker and then nothing. After checking the noisy speaker, the coil exploded and the driver is now bound up. The other speaker kept chugging along but doesn't smell nor sound too good.
After making a few phone calls to different speaker repair professionals, i was given some very good information. Bill of Millersound gave me quite a bit of helpful info pertaining to upgrade modifications to make to the drivers. He figured that so long as i have to have them rebuilt from the ground up, i might as well do them up gung-ho. Only problem is, Bill is really busy and these upgrades / driver rebuilds are so time consuming that he said that he could not take on such a job at this time. On top of that, he said that he doesn't see the time coming up to do anything with them in the near future either. Talk about getting one's hopes up and then having them smashed to pieces.
Having said that, Bill was kind enough to make me aware of the parts needed and what was involved in doing this work. Only problem is, i simply don't have the time to do this myself. On top of that, i'm going to end up filing a claim with my local electric provider, so i can't dilly-dally in terms of time or shopping around for a bunch of estimates.
As such, what i'm looking for is someone that can dis-assemble my Walsh drivers, clean everything up and rebuild them using very specific parts that i'll specify. From what i can tell, these are VERY unorthodox parts that nobody would ever think to use on this driver. This would primarily be due to all of the modifications involved to get them to work properly as they were never designed to work on this type of driver.
In effect, these drivers would be completely re-designed in terms of the suspension used and the electro-mechanical characteristics. Given that these are the hardest dynamic drivers to work on in stock form ( i've been told this by several different speaker repair facilities ), i can see why the average "speaker refoamer" doesn't want to tackle such a project. I'm not against doing it myself, but as i stated, time may be of the essence once a claim is filed. Any suggestions as to who to talk to about such a project? Sean

PS... During my conversation with Bill, he spoke phenomenally highly of these drivers, both in stock and "super-rebuilt" form. His thoughts were that no other driver that he has ever experienced offered the bass response and extension that this driver did. As i've mentioned before in these forums, i also share the same thoughts. The fact that they have the potential for very drastic improvements over what they offered in stock form really has me stoked. Maybe this isn't going to be such a bad thing after all : )
