I live in a small aprtment in Japan. My room has huge dips between 80Hz and 100Hz, confirmed with REW measurement. I can’t install large number of bass traps because

  • Installing bass traps to the left rear corner blocks the way to the hallway.
  • There are windows on the right side of the room.
  • There is a sliding door behind MLP.
  • The walls near the right speaker is located have an outlet and a ventilation hole, preventing me from installing bass traps very close to the floor. The walls near the left speaker don’t have outlets or ventilation holes, though I want to install same number of traps symetrically.
  • The ceiling is little lower around front corners (about 2.0m. other places have 2.4m ceiling)

I’m thinking of importing those ATS acoustic bass traps to Japan via MyUS because bass traps sold in Japan are poor quality, or prohibitively expensive. DIY could be cheaper but requires some time and effort.

If more traps are really needed I could mount more traps on higher places on the wall this way, but I’m afraid that installing many traps in this way make me feel I’m in a even narrower room.

I’ve also seen claims that dual subs could solve standing waves, but is that true? Even if that’s true, could that be very annoying for my neighbors (even with very low subwoofer volume)? I currently only have front speakers (ELAC DBR62).

    Bass traps behind speakers can help with dips…you will need an air gap equal to thickness of panels….GIK has bass traps with scatter plates so you don’t deaden that small room too much.

    Multiple subs would need DSP help for delays and integration…and aren’t effective above crossover.

    PEQ can lower peaked frequencies, making nulls less obvious.

    In small home studios they put the speakers right up against the wall to minimize speaker boundary interference…or at least to push the problems to higher frequencies that are easier treated

    Try sitting closer to speakers for more even bass.

    You will probably need 4 larger bass traps to make much difference
