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

Thanks so much everyone for the great help.

Bob, so I'm on a hunt for a crossover. I knew about the SMS but not it's cutoff range. Makes me think I may have to choose between having a too-low cutoff or going full range on the ProAcs. I wonder if there is also the consideeration of how high the subs work well, if I'm trying for a high cutoff.

Any ideas on where to find a crossover with high enough range? Perhaps I could have one built?

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?
