High ceilings and hardwood floors

I found a similar problem with my room, to compound the problem the rear wall was a large patio door with vinyl verticals. I considered selling the house upon first listen. I put down a large area rug on the floor, and hung heavy curtains in front of the patio doors. Both of these endeavours were acceptable to the spouse, she picked out the stuff. After that, I wanted to do a full treatment of the room but ran into a brick wall, very very low WAF. Next, started changing equipment and cables, tubes sure make a nice difference. In the end, the brightness was tamed, the room looks acceptable, and I hafta admit, sounds better than I ever thought it could. Jeff

Gonna have to put a carpet over those nice hardwood floors. Your room dimensions are to die for and that 16' ceiling should be wonderful. Maybe a large area rug, leaving a few feet of wood floor showing all around would do it. Don

You have a 16 x 16 "shoe box" which will have a nasty double reinforcement at whatever frequency has a 16 foot wavelength. Invest in acoustic treatments, especially bass traps to tame that resonance. Other above advice about rugs, curtains, and other furnishings will help as well.
