Sounds good.
I have always been one to want to know how a sub (and speakers in general) sound in my room. Subwoofers that are not setup correctly in rooms other than my own can sound dramatically different. Over the years I have proved this to myself time and time again. I actually do have a dealer that has a MKV-15 setup in a demo room and it sounds like Cr*p. Sounds decent for HT, but nothing close to like it sounds for music in my room. It's not EQ'd and you can tell! I'm sure he has several standing waves by the way it sounds to me.
EDIT: Remember that the MKV-15's can be hard to dial in as has been already mentioned. More than anything, that means that it would be easy for a dealer to screw it up. People I think are a little too paranoid about the difficulty in setting up the MKV-15. You should take time to properly setup any sub. I think where the confusion is that when people place them in the corners the MKV-15 really can get LOUD, so you just have to calibrate accordingly. Placing the sub with the PR facing the corner is best for music and movies if you are going to place it in a corner. I personally felt it sounded best away from the corner. It still puts out amazing SPL while sounding tight as a drum for music. It will be different in every single room, but this is not peculiar to the MKV-15, it's true for ALL subs. Testing in ones room is always the best no mater what speakers you try.
Anyway, from what I hear from people around the internet, they are mostly sold by custom installers though. So good luck finding a BM dealer who has a demo.
