Did some tweaking this afternoon...
So I think I have this issue resolved. Placement wasn't a problem. I think it was simply the volume I was listening to them at.
Audyssey had me level match them with the gain on the XS to around the 12 o clock position. Afterward I re-matched them with the gain just past 1 o clock. Today I re-matched them again with the gain at 2 o clock. Holy smokes... big difference.
It looks like Audyssey had them level match at 75db, I ended up setting them at 85db, plus running them 5db hot through the AVR level adjustment. I'm either a huge bass head or Audyssey was taming them to much for my lower listening levels. All in all I am running 15db hotter than Audyssey wanted. But I love it!
When Sauron falls in the Fellowship of the Ring.... The XS is astounding! With the levels up now, it shows how much deeper it can go than the Klipsch. REALLY impressed.
I've still only had the unit a few days, so I'm not saying I won't still end up going up to the XV, but I'm WAY happier now.
