I'll offer offer a few observations, some first-hand, some gleaned from general consensus. The manufacturer regards the Model 1 upper end as slightly more refined than the Hawk, the Hawk clearly with more bass depth and extension. I've heard both speakers, but only the Model 1 in my own smallish room, which is about 16' x 11' x 8' - not as square as yours. Well set up, with adequate power, for the type of music you describe, in that room, I believe the Model 1's an excellent candidate. Would you prefer the Hawk's greater depth, even at the expense of a sliver of high frequency insight? That is such a personal choice...UHF magazine made just that comparison a few years back, I don't think they were able to be conclusive...
The manufacturer and many Totem lovers regard the Mani-2s as operating at a more elite level altogether, with substantially more refinement, and more real depth. As well they should at the considerably higher price... By all accounts they are very power hungry and particular about partnering and set-up, but very rewarding if well propitiated.
