I believe i saw in one of the first posts he had a pair of the 152i guides. Does anyone know why he moved away from that WG? It would seem that the wider baffle required would have helped with diffraction of the midwoofers as well as reduced the need for BSC. There's so many nice buyout woofers over at PE, i'm tempted to take up a similiar array type system. Using those midwoofers and the 152i along with the D220i, it's possible a serious performing system could emerge on substantial budget. If anyone has any thoughts on the subject, feel free to post. I'll put together a thread if i head in that direction.
