One last attempt to try to get to you:
@domic and I'm rarely known to give second chances.
Did you ever see original UK's Top Gear. Specifically Series 6 Episode Two - part two of
Cheap coupés that aren't Porsches challenge.
Presenters asked to partake in what eventually discovered to be endurance rally test.
Clarkson bought a 1991 Mitsubishi Starion and installed a huge turbo on it.
The outcome was unexpected - while Clarkson's new turbo made the Mitsubishi the fastest car in the entire race, the engine repeatedly overheated and broke down after almost every lap, before one last blow up put him out for good.
What you're doing is about same thing as Clarkson did. You're trying to modify a speaker in way which was not designed. Parts gets damaged from misuse. then you come here and ask for advise how best to continue to abuse the speakers.
My advice is same other folks. Drop this foolishness and start from scratch. Then I was young and poor, I asked out day my mechanic a question about my old '99 Corolla - what can I do to make it go faster. His answer was simple - buy another car. I waited a bit and did buy newer faster car. One which was designed to be faster from all aspects and stuff I couldn't possibly even consider.
