The 2-channel/multi-channel hook up fixed it for me. I'm happy with the Abyss so far.
Had actually purchased a floor-model Dynamo from Tweeter for 330$ and was impressed with it but then they had the Abyss on sale for 550.40$ (brand new, too!!!) so I upgraded and I think the 220$ difference is well worth it. They will try to give you the floor-model Abyss to at that price but you should just insist on a brand new one if they have any left.
Night and day difference between just using the LFE vs. the 2 Channel mode. I have my single LFE out from pre/pro and hooked up to the L & R inputs via a Y cable.
I tested with Matrix after the lobby scene where Neo and Trinity are in the elevator. When the elevator crashes down and explodes there was absolutely nothing with my JBL 15" and I always wondered if I had a defective version of the DVD. This time with the Abyss, I was finally able to hear and feel the low end frequencies from the explosion.
I'm very happy over all with the sub, but still couple outstanding issues for me; minor gripes.
1. Seems too lightweight. I guess that's good since easy to move around, but doesn't give me a feeling of quality (not that weight necessarily has anything to do with that).
2. The power cable is suprisingly chintzy. Not even as thick as my dvd player cable. (Would thicker power cable do anything?)
3. The listed magazine review of the Abyss said that it has better low end extension with the LFE input. Don't know how the reviewer got any output out of just the single lfe input. Really, how does anyone get enough output with just the LFE connected. (Is the lfe connection on my sub faulty?)
4. The broken 90* rca adaptor.
How would a second Abyss sound?
Really like the sound of the Abyss so far.
