Bob, thanks so much for the great info and pointers. I'll have some work to do to thoroughly check them out.
With the RM9 I felt I was pushing the One SCs to their conservatively safe limit in my 11x12 room. I think if I try to run them full range in my much bigger new space it will be too much for them, so I do need to find a satisfactory way to divert the lows to take advantage of 1/f power spectra. I also agree that 80 is too low due to the small woofers in the ProAcs. As well as that first order is not going to be decisive enough. I took a glance at Marchand and that looks promising. I run JL in my car, and the amp has a good tone, if dry compared to my tubes. Shouldn't matter on the sub.
I do wish it was not so difficult to find a very nice pair of Response 2.5s.
Thanks so much.
Jim
