Best small monitor speaker 4 small room acoustics?

I've been using using Merlin's excellent TSM-M 2 way sealed box monitors for my small HT/Music listening room as of late. I've played around with so so so many small rooms, and different gear in them, fidgiting extensively with potential speaker placement/seating arranement scanrios, etc. In all my years of tinkering, I have yet to find a better chioce for a flexible small room monitor for HT/Music dubties than the Merlins!!! When you're in small acoustic spaces, getting flat "non-boomy/peaky" sound from speakers is challenging. And the limited frequency extension and sealed box enclosure of the "easy to drive", tube friendly, TSM's allows placement nearer to walls in smalls spaces for proper balance!..something not easy with "ported" speakers. The Merlins are truely world class "passive" speakers, and cross over nicely at 80hz when set up right for doing DD/DTS with a sub!
My question is, has anyone out there had great experience with other speakers in small spaces?...which ones?
I've experimented with a ton of otherwise good speakers in small rooms(my current space is 12 X 13 X 8, bigger than in the past), such as Dunlavy SC1's, Thiel SCS3's, Thiel PCS's, Sonus Faber Minima Amators, Energy C2's, B&W Matrix 805's/601's, etc, NHT VS2's/1.5's,Super zero's/one's, Spenders, and a myriad of high and mid-fi type speakers(too much to list).
Again, I'm only trying to get feedack from people who've had good experince with higher end high fidelity type speakers in "small acoustic spaces" (i.e, smaller than 1400-1500 cubic feet). If you use a small room as your listening room, you probably know the problems associated with such rooms for good speaker/seating placment choices, and associated equipment. So, that said, any other comments on great speakers here? Like I said, I doubt you'll find anything better out there for small rooms that will do better than my Merlins! Thanks for any comments/suggestions
