I have a 17.5w x 26L x 9h dedicated basement room and my flooring is heavy carpet and pad over concrete. When I built the room I decided to use the 2x2 drop ceiling; I used a top quality ceiling tile. End result was that the room was too 'dead' overall. So, I removed approx. 30% of the ceiling tiles and inserted 2x2 cut-out plywood panels which I covered with nice speaker grill cloth. The grill cloth hides the unsightly floor joists, plumbing, and a/c duct work but allows the sound to pass right through. This was a major improvement. With this arrangement I don't think that I would want or need a hardwood or tile floor. Cheaper and easier than a new floor too. Another plus is that you can install the replacement ceiling tiles a few at a time and experiment with their positioning, effectively fine-tuning the live/dead balance of the room.
Hardwood floors in basement music room?
I currently have carpet over concrete, and I'm thinking about removing the carpet and installing engineered hardwood over a glued down underlayment, does anyone have any pro or cons on this. The underlayment I was going to use is a lumber liquidator product called Eco silent sound HD, they also have a cork underlayment .
