What driver does Phil have? I know he's real busy with the new baby and all, and that's why he doesn't participate here much right now. But I may write to him and ask.Phil's little speakers sound great, and they're a single driver Fostex in a bass-reflex box. He purchased them from that fellow in St. Louis. Nothing to 'em - 8" driver in a simple ported box and no electronic components 'cept the driver.
