I have a few leading proposals that I will test today:

Anyhow, I have no idea what it is and I need to provoke the horn to tell me what went wrong.

Hi Romy:

I doubt that this is the answer to your horn problems but if you recall, when we talked about the possibility of high temperatures affecting performance, maybe you might investigate whether the drivers still perform as they should given that 'burning in' with the throats 'plugged' might have resulted in very high temperatures building up with the drivers effectively sealed back and front, even with relatively low power requirements.

Just a thought.

Clearly the first thing to do in my mind is check state of the drivers, then take out foam and see what happens. You may also want to check the wiring you have used, given the extensive lengths involved and take some measurements there, possibly use some shorter lengths by moving some amps closer to drivers.

I hope it all works out as I love the idea so much I would like to copy it!!

All the best
Rakesh
