How to integrate a sub with 2-channel mains?


I've done a ton of searching and haven't been able to come up with an answer to this... Hopefully some of you can help!

I currently am running a DIY BP1503 for my home theater/television, and it is everything I want for that. Howerver, I want to get a second sub for 2-channel music; probably a UFW-10, something much "faster".

What would be the best way to integrate this with my mains? I've seen many people post that they did this, but as near as I can tell, they are not using their processor to xover the mains and sub... How do they hook these up and cross them over?

Thanks in advance!

Thanks for all the replies!

Abrahavt - how would I use the ICBM? just use it for the sub?

Radiob - do you use the x-30 for the sub only, and run the mains full range? I'd like to avoid any unnecessary processing on the mains if possible.

Aroc - your technique is exactly what I was thinking. Is it better to run the mains full range and augment the lower registers with the sub, or to cross both over?

As far as outputs; I am getting an AVM30, and I don't think it has secondary outputs; so I'd be stuck with speaker level inputs. How is this done? Attach another 2 wires to one of the speakers binding posts, and run it to the sub?

Beatlebum - I knew the bp1503 would be too "boomy" when i finished designing it; the alignment has a mid-q, around .7-.8 IIRC; I think it's better now to use it for HT and get a smaller for music.

I was looking specifically at the ufw-10. Here are the specs:

Other Features: One-band parametric EQ (freq, bandwidth, and level), continously (infinitely) variable phase, gain, and crossover adjustments (40Hz - 150Hz), crossover disable option, LFE summed R/L RCA input, balanced mono XLR input, auto-on / standby mode.

Thanks for all the responses! Sorry to keep asking newbie questions!
