I bought this to check how my stereo mixes translate in the mono domain and also to keep an eye on how the midrange responds on a single driver monitor. It hasn't disappointed, the build quality is superb, the psu 'brick' design and build appears very rugged. You don't buy these things for sound quality, rather more for worst case scenario's. It appears to do this well and certainly helps improve mixes.
Only minor quibble which is more due to my desk layout than anything, I would have liked to see the power switch on the front, rather than the back, but other than that, nothing bad so far!
