Hi everyone, my name is Roy I live in Tampa,Florida,USA with several sound system we use for playback. We'll be starting soon a new 4 way sound system for large scale crowds up to 2000. I want to build 2 MTH-4654 with the RCF 21" neo initially to try this wonderful plans I actually brought it with me at a recent show in Orlando the 2011 InfoComm convention. I showed the plans to Tom Danley and he said the horn path is right for the 18" and a 21" will really give very good output, so I have a question with regards to the baffle hole is for the 18" woofer is it the same with the 21" RCF or larger? It is not clear in the plans? Maybe someone has some inputs on here? Thanks everyone!
