that's what's in the back of my mind ..... the one cone needs replaced.
I learned something today - even though I thought I had rebuilt the other 3 surrounds perfectly without using a test tone ... I found one rattling.
By playing the test tone, and then by exerting just a little pressure on one spot of the surround, the rattling ceased. I suppose that's telling me that I didn't get it centered as well as I thought ?
What I don't understand is, I can press down directly on the center of the cone until the cone bottoms out, and not detect any rubbing whatsoever, but the 30 and especially the 40 hz tone test reveal a rattle. CRAP !!
I'll probably need to get all new surrounds, because I'll bet I'm not too successful getting these unglued. Do you think ?
I have learned a lesson in speaker repair. I must have just been darned lucky on the others I've done, including my L300's. No rattling detected on those with the tone tests, but lots of wall and other crap rattling
