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 again guys.

Sc53 is the Neutrik made by REL or is it separate?

Erik, I wish I coujld afford a D30R right now. I've spent some time listening to the D40R, it was magical. Has to be in my future though.

Bob, yes I am worried about that stress. While sending some bass energy to the sub will help, still it's a big space and I do listen loud. My RM9 will easily overwhelm the One SCs. I guess I'll just have to find out. If I end up selling the ProAcs the sub will be useful anyway. I wonder if it would be useful to set the high pass at a higher frequency? The woofers in the One SC are small.

Velodyne makes the SMS-1. Don't know if it has a parametric or if it differs from Hsu's network. What is the advantage of a built in high pass vs. the REL with an external?


Thank you,
Jim
Jim, yes REL provides the Neutrik cable, although you can also buy after-market upgrades too. I had one made by somebody here on Audiogon some years ago, now I see that Kimber makes one specifically for REL subs, I think Signal Cable has one too. Try the standard one first, and follow the tuning procedure in the REL manual. Setting the crossover LOW (perhaps counter-intuitive with such small monitor) works better 90% of the time, but your room and ears and music will be the guide.
If you are concerned about overdriving the main speakers, you should go with a fully active crossover/subwoofer system that actually cuts off the main speakers below the crossover point. With such a setup, the best sound will most likely be with the crossover set at a quite low frequency, as others have mentioned above. I almost always find that for music, a low crossover point sounds better.

I haven't listened to that many subwoofers, but, of those I heard, I liked the Martin Logan subwoofers that I heard coupled to quite small Totem monitors.

While the REL does not cut off the main speakers in the low frequency, I have been impressed with how easily REL subwoofers can be integrated into a system.
River251, I recall you being located in Phx. Check with AZ Hi Fi re the Gallo subs. More flexible in setup than Rel and deliver a sound that isn't designed as "bottom up".
