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).

    This is certainly a room mode cancellation (and is extremely common for smaller rooms). It’s a function of the speaker positions in the room as well as the listening position.

    If you’re unwilling to move them out into the room, you can try moving them left/right as well as move the listening position left/right/forward/back to see what it does.

    Bass traps will certainly help, but they’re not going to magically fix a 30dB null.
