Which REL subs for ProAc One SCs?

Rhljazz, good memory! I do go to Phoenix HiFi, but live a little ways off in Las Cruces, NM. I have talked about going to Phoenix HiFi in this forum though, so good eye.
They are nice guys with lots of lovely speakers and I always leave their acutely aware of my earlier career choices :-).

Bob, this is from the SMS-1 manual. What do you think about being able to find a good crossover with the ProAcs and a sub?

16 - Digital Drive SMS-1 User’s Manual
All six presets contain the following fields:
•
Low Pass Crossover Frequency and Slope
– Adjust the upper limit of your subwoofer’s frequency
response. Select a crossover setting, in increments of 1, between 15Hz and 199Hz and slope at 6, 12,
18, 24, 30, 36, 42 and 48 dB/octave.

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
