Speaker repair-need help

Sorry about your loss.

I really doubt that you can get anything out of the power company. It is a fact of life that power goes off and back on from time to time, and electronic equipment that can't withstand this is arguably faulty. When you tell the court how many watts you have hooked up to these drivers it will be all over.

If you don't want this to happen again (power coming on again) what you need is a "latching relay" in your AC power...maybe just for the prepro. Or fuses in your speakers. Simple fix either way.

Sean...Why the tease? You have told us that the Walsh driver has all these faults, and you have ways to fix them, but we have not the slightest idea what you are talking about. Quite frustrating to your readers.

Sean...Although I am a long time admirer of the FR Walsh driver I am not familiar with details of how it is assembled. However, as an engineer, I offer the following suggestions.

1. Big picture...The existing design appears to be difficult to build, nearly impossible to repair, and requiring a lot of skilled manual tweaking. It seems to me that this design was taken from the lab directly to production, without the essential step of industrial design/producability engineering. Redesign the thing so as to retain the basic concept of the traveling wave down the tapered cone, but with simple more automated fabrication as a primary goal. (What is the patent status of the Walsh driver?)

2. I always wondered about the basket legs getting in the way. Why not use a massive "C" structure instead of a basket?

3. Don't worry about efficiency. Powerful amps are cheap today, and (with digital technology) getting cheaper.

Send me a copy for evaluation :-)

Gregm...Sphere? I don't understand. You do realize that the sound comes off what most people would think is the back of the cone. My C structure really gets rid of all the basket legs except one, and that one would need to be strong.
