  None of the above are going to help very much.

  The cheapest and sometimes most effective room treatment is just repositioning your speakers, equipment, and other items in the room. Can have a significant impact on sound. If you feel you need to treat a room because of frequency anomolies, try putting a thin foam mattress pad (the eggshell kind) on the offending wall/corner. This will help with high frequencies. Your could also build your own sound panels made out of 3/8" ply wood and 2/4s, using pink insallation and chicken wire to hold the insallation in place and cover with some sort of fabric. Will help with frequencies down to about 200hz.

  Good luck

    Not recommended, due to unpredictable resonatro suck-out effects.

      I do not agree with your statement. Using this type of sound treatment can be very controlled as far as the energy frequency domain if you know what frequencies you are trying to damp. The more of the insulation used the lower the frequency affected, down to about 200hz. The energy absorbed is essentially linear. I have tested this in my room as well as several other friends rooms with a TEF unit.

      The danger in using this type of modified live end dead end approach is it only addresses back wall reflections and side wall reflections out to where the sound pannel ends. It does not address ceiling or rear wall reflections.

        I am talking about the plywood on the back of your sound absorbing panels.

        I recommend a design that uses only the kraft paper backing of the fiberglass, and a wrap of polyester batting on the rear.

        If 6" or 8" fiberglass is used, the absorption will be very good down to quite low frequencies, especially if the panel is spaced away from the wall, as outlined in my DIY note.

        Please read my DIY notes first.

  Not having Mrs. Worthog around is great! I used fuzzy but thin blankets (the color of the walls) to cover the area behind my Maggies(floor to ceiling). Also the ceiling. (bass can hid in the ceiling.) My room is what is called a live end dead end. Live where you sit and dead where the music is played. Merry Christmas and good luck, bobwire

  Large leafy plants in bass pots can be put in each corner. that will do some amazing things.
  enjoy

  Didn't Stereophile recommend using stacks of cardboard boxes filled with crumpled up newspaper and old magazines a while ago? (Never tried it myself.)

    i believe i have read this before in one of their issues. not sure which one. haven't tried it either. we have lots of boxes and newspapers. problem is i don't have the space for the boxes. moreover, i will be using the long side of the wall.

    Stereophile did mention cardboard boxes with newspaper, it was in a review written by J-10. It was done by the Shun Mook guys. I did this for a while and found it to help a bit. Another words, much better than nothing. I also had a 2ft stack of newspapers that were sitting on a hassock on one side of the room. Removing the stack of papers had a major negative effect on sound. The empty cylinders might work, try stuffing them with newspaper and place one or more [stacked] in each corner of the room. Also the cork board might help by placing it behind the speakers and on the side walls at the point of first reflection. Also try some on back wall behind where you sit. None of these will be as effective as the DIY ones that Jon Risch designed. If you are having bass problems try the Quick & dirty Bass Traps, see link below. It might help us to know what you are trying to accomplish with the room treatments.

  until you can do it right.

  Follow JR's room acoustic treatments links and for under $100 you can do real good rather than placebo good.

  Also, cars that come equipped with leather seating usually come equipped with premium sound systems, so it might not be the leather, per se, that's responsible for what you heard.
