hi Bill
First off,good luck with your speaker hunt and have fun.
Going by your room size,17x28,you would have no problems with MB2 or IB2.And depending on your average maximum volumes(110-120db??)the midrange would play a big part.If your max. volume does not "ever" exceed 110-112db,the vifa mid will work.Dont get to caught up in the "i" tweeter as it is not worth the extra thousands of dollars they ask for it.You can find a good used pair of non "i" MB2/IB2 for the $7-$8000 range with stands.
