Agree mini Maggie's are a desktop system, but for a small room set up they need to be treated like regular bookshelves with stands and an extra bass panel
I don't think you are implying this, but it doesn't make much sense to buy the mini's for a small room set up. A set of 1.7's could be had for around that price. I don't think ideally placed 1.7's sound better than ideally placed Mini Maggies, I do think they are more practical w/ regards to much wider sweet spot and easier to set up for a small home theater set up
I have not heard the KEF LS50, but the Mini Maggies are by far the best sounding desktop set up I have ever heard. Easily recommended. The speakers really do sound like full scale Magnepans just w/ a narrower sweet spot.
I took some updated measurements with my non-ideal set up, 1 satalite at a time to eliminate combing effect in the previous measurements, and taken from near field. They were a lot more impressive than my previous measurements, unfortunately the program crashed before I could save a copy. I'll post new measurements in a couple of months once I get the SVS Ultra 13 and my new place.
