I have a room that sounds just like yours - 3000 cu. ft. that opens to a kitchen. My Velodyne SPL1000 is very tight, detailed, and will blow you out of the room if you let it. It may cost a little more than the others mentioned here, but, IMHO, it is pure class. Plus, it's small and easy to integrate into a room. I've seen & heard some SVS models, and they were very impressive, but HUGE! If SWMBO will acquiesce to the presence of one of those monsters, go for it. I've got to live with unobtrusive.
