I already have both. I bought the Klipsch from a friend for $150. I already had the abyss (10"). I'm trying to find out if tuned properly which one would be better. The abyss a 2010 model and the Klipsch is the first rsw-10 - it's old. I have an Onkyo HT-RC180 with dual sub out, I believe they have to the same sub to use both or can I mix and match.
I have vaulted ceilings and it's 20(w) x 15(D) room (I think). I know for sure my room was considered a med size room when I was doing research for room size.
