my room is fairly large 14x24 with an opening on one side into a dining room (about 10x12) and kitchen. I have a large bay window, 10ft vaulted ceilings, and hardwood floors with some marble floors in the back of the room. i have an area rug and drapes but i feel my room has a kind of bright sound. in terms of adjusting my audio system should i lower the treble a little to compensate for all the hard surfaces in my room? any other audio adjustments i can make to soften the sound?
