I have them, though they are now put away. I was using them as my l/r for stereo and for 5.1. Thought they were good. Nice cabinet, solid, small. Not the deepest bass, but that's their design. Still, pretty potent. Comparing them to the av123 reference 1's that I have now, I'd say they weren't terribly far behind.
As soon as I can get the mounts and a go ahead, will get my Aperions up as rear surrounds. This may never happen, as I get flak for the "big boxes" already in view. Imagine if I had some Maggies...can you say the d word?
