Speakers & the room


After a couple of years playing around with different speaker positions I came to a conclusion.My room sucks..No matter what I do I can't get it right..My room is about 15x24 with 3 different ceiling hights..My speakers are about 5' from the back wall and 3' from the sides.This seems to be the best but it's so far off from what I want.I have moved my listening position everywhere also.If I sit at the same distance away from the speakers as they are apart my imaging is great but I'm missing the bass and the extreme lows.And of course if I move my listening position farther to the back wall i get great bass but the imaging vanishes.I hear very large tonal changes with even small changes in my listening position.is my room doomed or is there help?My speakers are Artemis/EOS full range with tons of acoustic treatments from auralex.Any help would be appreciated..

Hello Spaz,

That's some lovely equipment you got there.

Eyeballing the pics on your System page, two things sort of jump out at me: Perfect symmetry, and lots of absorption panels. In my opinion, therein may lie at least some of the problem.

As you move between areas in the room with absorption panels exactly opposite your ears to areas with flat, reflective areas exactly opposite your ears, yes the tonal character is going to change. If you had diffusion panels spread about with some asymmetry, and relatively little absorption, then the soundfield throughout your room would be more uniform at midrange and treble frequencies.

In an effort to give you less variation in bass from one room location to another, let me suggest going with a semi-diagonal setup. For example, imagine looking down on the triangle formed by yourself and the speakers, and rotating that triangle about 30 degrees clockwise within the room. This will stagger the distances of your two bass sources to the room boundaries, which should result in a smoother bass summation pretty much throughout the room.

Finally, if you still aren't getting enough bass at the listening position, it's not cheating to add a sub. In fact, adding a third bass source (also positioned asymmetrically) should smooth the in-room bass even further. If you really want to go all-out with that third bass source, mount it closer to the ceiling than to the floor. This will significantly stagger your bass sources in all three dimensions.

Best of luck to you.
