MDF for walls in music listening room

The best room I ever heard simply used 8 by 2s instead of 4 by 2s, and with half the spacing, then used double thickness of drywall, and obviously treated the drywall. I suspect the amount of MDF you would need would be very expensive compared to other viable options.

Rives -

I have a concrete basement room I am going to finish/spruce up for a listening room, about 20x13x7-8 or so. Where can one find that Owens Corning panel material you have spoke of in the past? I was thinking put up some reasonably absorbtive panels (such as that stuff ) with drapes over that, should cut down the liveness somewhat, and be a lot less work (and easier to redecorate w/ new draping fabric) than Drywall. Any thoughts, offhand?

Ed: Why not have us design your room? Getting the material is not difficult, many building supply places have it or can get it. The trick is knowing how much to use and where. That's where we can help and give you a first class listening room using these types of basic materials--thus not breaking the bank.

I like OSB vs MDF idea and yes definitely use drywall to finish. Like Rives says you don't want to use too much rigidty and have the room not absorb.

If you have some specific question with detail I am able to give you some direction based on room dimensions and detail built into the walls. I will even do a basic RT60 calculation for your room with and without OSB/MDF and chart the axial mode that can be plotted for comparison against ideals. No room is perfect even after extensive planning and some tweaks are necessary. If your room is for HT the demand is less stringent because almost everything in HT is fake and loose, kinda like golden topping.

email me if you care to discuss

Rives - thanks for the idea - will take that into consideration and likely be contacting you in the somewhat near future.
