In my sonically difficult room I experience a lot of bass gain and have used bass traps to great advantage but still experience some bass boom. It happens with with any type of speaker and I have changed placement and room arrangement until I've exhausted every feasible layout. After experimenting with rolled up socks (which the Mini T can spit out) and realizing some benefit, I ordered port plugs for my Mini T's. When plugging both speakers the bass output was reduced a lot, almost too much for my taste. Experimenting with a test disc and spl meter, I found that the best results were achieved plugging only one speaker. Since bass frequencies are not directional there is no effect to imaging. The mid bass is cleaner which also seems to clean up the midrange also. An asymmetrical room required an assymetrical solution. The left speaker is plugged. The left side wall runs the length of he room. The right side wall is only about four feet long before opening into another part of the room.
