Just thought I would add my 2 cents too this discussion. I added a pair of JL audio e112s with a JL audio C1 to my dynaudio C4s and am very pleased with the results. it took me a long time with a lot of sub / main speaker placements, crossover adjustments and sub volume changes to get a sound I liked. Barry and his coworker at JL supporting home audio equipment were both very helpful and a lot of fun to talk to. Two things I would recommend when setting up subs, first get Barry’s setup cd and try positioning a sub forward of the mains and one to the side of your listing position. In my setup I found that putting subs in the logical positions in my listing room , next to and slightly behind mains caused a murmuring sound (I think it was group delay). In talking with Barry at JL he pointed out that putting subs behind mains causes the main speakers to vibrate/rattle from sub output. He also told me how he setup recording studios with subs forward, I tried subs forward and it worked for me. Finally, as lots of people who have tried integrating subs know, it’s a bit of a black art.
