Thanx Jim. I have been into single driver stuff for about 18 months now, and have built a pair of homemade speakers using a vintage pair of drivers that are extremely satisfying oto me (and to some others who have listened). Your response is important becuase it allows people like me to BYPASS all the other stuff you have tried, and lerarn from your experience. I was thinking powered sub too, since i use really low powered amps. BTW, anyone here ever try the Hsu sub? -akhilesh
