The center channel I made uses two Fostex FE127's (plus a KSN1038). I'm a sucker for highs (or my hearing is crap after 100Ws of Traynor amp in my bedroom when I was a teen. Nah. Couldn't be that.). Anyway, I'm really impressed with the Foxtex drivers. Not cheap, but sound pretty nice. The first Fostex pair I made were TQWTs with some cheap RS piezos. Those are FE207s 8". No complaints there. I have another pair I ordered by accident, really. Haven't made boxes for those yet. Those are FE167's. Chris
