Hello, so..I just put in my golf 3 so metal rings, from Nokia, then I was finished after a few hours, just put on the last screw, and then it happens, I slip off and land in the middle of the membrane…. Now there is an approx. 1.5cm long slit in the membrane, then I called www.wooferstore.de where I bought it. Mr. Krystek (owner) said that he could possibly get me a single box. He then gets in touch on Monday….OK what do I do now. Ic h was just outside again, I’ve heard a try….so I don’t hear an extreme difference, not even when you turn louder…. Has that ever happened to someone? Or can I leave it with a good certain amount, well I’m kind of perfectionist and everything has to be good etc…. oh ****, and that Friday evening — please help me, where else can I get a single box, oh yes the system is: Rainbow SLX 265 “deluxe”
