Well, the room is open concept, where the living room opens into the kitchen. It's a Florida house, so it has 10 ft ceilings. The speakers are 2 feet from a side wall, and one foot from the rear wall. The left wall only come out about 3 feet, then opens into an entry way that is roughly six feet wide. The floors are hardwood/tile, and has leather furniture. Could provide dimensions/pics offline if needed.
Not quite sure about application. They are used for music/television, and two channel home entertainment. The electronics are a pair of Devialet D-Premier integrated amps, which output 500 watts per channel @ 6 ohms. Also occasionally use tube amps that are either 80 watts or 110 watts.
I really like these speakers, and have not felt the need to replace them. However, given their age, if improvement can be had, I'm all in.
