I have a brand new 8 litre diy speaker kit I just bought from Brian at decibelhifi. Cost me $230 shipped from Australia. I thought I'd have some fun with it but I just don't have the time. Fits the JX92s drivers perfectly but can use almost any other driver with minor changes or turning the front cut out the other way around. I'll consider all reasonable offers. In hindsight, it won't cost much.
