Which REL subs for ProAc One SCs?


Bass was fine in my 11x12x8 room. I'm moving into a new home with living room, dining room, and kitchen all forming one space with 12 foot ceilings, and a hall going off to one side at the kitchen.

I'm hoping subs will let me keep the One SCs which I love, and it seems RELs are popular.

Which ones should I use, and do I need two?

Thanks
Jim

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
Jim--I know of a pair of Response 2.5's for sale!! Where are you located? ProAcs are remarkable speakers, I've loved every model I've ever heard, big or tiny.
No I have no insider info on D38's! But I do know of some 2.5's available in Oak finish.
