The feedback that I got was that there were a few issues with them at the show.
I knew that they'd be a freshly assembled pair with little play time on them when they arrived and that would have held them back a little.
From what I have heard from a discerning listener was that putting a speaker that large (with a total of eight 10" woofers) into a small untreated room caused some issues. The bass loaded the room a bit much and there may have been some room related peaks elsewhere in the response.
However, the same guy told me that a lot of people were really digging it.
