    yes it is going to be pro looking and sonically should be very nice place to listen to music

    normally pro studios tend to eliminate side wall reflections and diffuser are installed at the back wall in this design i am giving reflexions a very important place an these are being encouraged in some way

    central parts of the front and back wall will be dead
    there is also some broad band absorption in the lateral walls

    Foam or fiberglass? (Kinda sounds like "paper or plastic..." is that only a US phenomenon?)

    How deep will these panels be?

    Foam or fiberglass? (Kinda sounds like "paper or plastic..." is that only a US phenomenon?)

    How deep will these panels be?
    Mineral wool (roxul rw60) to be exact which is the one i can get down here and its cheaper than OC 703 or 705

    the lateral walls broad band treatment per side (3 units of 2x4 foot) will be 4" deep plus 6 diaphragmatic tuned bass traps units with 2" of mineral wool to make the trap a little broader in response
    the qrd diffusors are 9inch deep that way they will cover all the way to 300hz

    the back wall central part will be covered by 4" mineral fiber panels and to the sides instead off the qrd as shown i will implement flat phase changing diffuser absorber panels

    front wall central part will be 4" air 4" mineral wool and too the sides to large diaphragmatic units tune to 65 hz+-

    the ceiling will have a 2d qrd 4x6 unit 5" deep which i already have at first refection point.

    and in the USA check out for the Roxul AFB (acoustical fire Batt)

    2.8lb/foot density

    best bang for the buck


    RW40 is even better than rw60 and cheaper, i cannot get it here in Mexico

    i have used rw60in several installations with excellent results

    I got the mineral wool material in my absorbers instead of the Owens-Corning glass and am very happy with it. After hearing samples of each, I was convinced mineral wool was the better option for me.

    Cool Project

    Make sure you aren't using any of this drywall!

    Photo Bucket

    I see you are still using a photo hosting site. Why not just post them here. When photos are posted into the threads here they are always available... unfortunately when people use their own website or any external site the links may get lost and we can end up with this:
