Speakers & the room

Ditto Pubul57's suggestion on getting a consultation from Rives.

Consult Rives or consider posting this along with a diagram of your room including all relevant objects to the room acoustics thread on AVS forum. The latter is free but you will have to decide for yourself among the many opinions you will get.

Your room is nearly a multiple of 7 to 8 feet in all dimensions. Try a TACT or
Rives PARC. Try sitting at 38% or room length. Keep your speakers well out from
the rear wall (at 6 - 8 feet). Try placing the speakers closer together - away
from side walls ( 4+ feet ).

Also try Superchunks or GIK Tri-traps - this will be more effective than even the
big bad Auralex LENRD's. (I'd suggest 8 GIK Tri-traps at the minimum)

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.

Sounds like a standing wave problem - alas, no thickness or amount of Auralex foam "traps" are going to ameliorate the problem...I've tried their offerings, and they simply don't work all that well (though I heartily endorse their quadratic diffusors). It seems like tube/bass traps are the best solution - while the ASC offering is certainly effective, you can roll your own for a lot less. Yes, it's messy and time consuming, but they are very effective. Take a look at Jon Risch's threads over at the asylum for construction info.

Good luck,
