The13thGryphon,
My living room is moderately large in terms of volume as the short wall is 9.5' high and it vaults up to 16'. The floor is oak hardwood with drywall walls. I think the accoustics are good in the room and this was backed up by an expert violinist who has played in the room and commented on how great they were.The floor plan is open to the main entry and the diningroom. We listen to a variety of music from old Pop/Rock to Classical and Vocal. Sometimes the playing level is loud, even though most of the time it is turned down to allow conversation.
