  I'd have to go back to "the literature", but there is some evidence which shows that "the corners" of a room receive more reflections than other areas, just from a statistical perspective. As a result, that's the best place to catch more fish. (Oops, I meant "absorb more energy".)

    Yes, and I see it as a focusing effect similar to cupping a hand over your ear. Or think of it like a TV dish antenna.

  Yes, for bass trapping anyway.

    How about for mid and high frequencies, besides the bass ?

    Should I place basstraps on 4 corners, and where the ceiling meets the side walls, should I place absorbers?

    Thanks to all those already posted - you are saving me tons of work, since I am new to this. I don't want to make big mistakes in DIY acoustic treatments.

      This is a deep subject, and a complete answer requires far more than will fit into a single reply here. The short version is:

      * Broadband (not tuned) bass traps in as many corners as you can manage, including the wall-ceiling corners.

      * Mid/high frequency absorption at the first reflection points on the side walls and ceiling.

      * Some additional amount of mid/high absorption on any large areas of bare parallel surfaces, such as opposing walls or the ceiling if the floor is reflective.

        Thanks a lot Ethan - exactly what I needed !

        I will definitely check your sight out.

        I am a musician, so this is very important to me - for my career actually. We are trying to make a few CDs, and this kind of expert advice is what I need.

        I just love the sound of a well tuned room - playing my favorite recordings ! ... and I am excited at the prospect of achieving that in my room.

        Regards,

        James
