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

I use two subs with my SC's, both are NHT SW2's, which have outboard amps. I have the subs on spiked amp stands, with cushioned auto wheel rings under the subs. How I came to that configuration is a long story, but they work very well. The only way you are going to know if two are better then one is to try them together. Purchase where you can get a return accommodation with full refund within 30 days. If one works, take the other back.
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.
