Found this guys website after looking at speaker builds for Vifa 5" drivers. I think its a very useful sight for anyone wanting to diy a pair of cabs. Nice clear illustrations, cab dimensions, xovers with layouts etc. Including the Tannoy Monitor Gold MG15 Crossover Up-Grade for those of you that have them.
