terrible bass response / unevenness problem.


im sure you all have experienced the problem i have here, but i need sugestions on how to tame the uneven bass response in my room, the bass in my room is just terrible. im already going to change subs from a 12" to a 10" sub. (room is 12 X 13)

the problem is mainly with the low bass frequencies, at cretain low frequencies, the level of the bass rises dramatically and resonates the whole room. terrible air shaking feeling. then as soon as the bass guitar in the music jumps up to a higher note, the sound is suddenly cleaner and the level goes back to normal. i want to find a way so that all frequencies are being heard at the same loudness,(and felt at the same intensity). the bass with my sub is also lacking any detail(integration problem?),. is dull and muffeled. i already tried moving my subwoofer from the front right corner of the room to the left front corner, which made a fairly significant improvement in the bass resonating/uneveness problem.

i was thinking of getting an equalizer, but im not sure of a good one to use for a home stereo setup. all the ones i see seem to be rack mount units. i know more bands are better, like 30 or so. i know they say that you should try to fix the problem another way, before going to an equalizer, but wouldnt an eq be cheaper than thousands of $$ worth of sound absorbant panels, bass traps, etc?.

ideas anyone??

James makes good products, but I would also investigate REL. They are available at a good many hi-end shops as well as some Tweeter stores. I've heard the James and the RELs and prefer the latter.
The dimensions of a room will cause low frequency modes (areas of reinforcement) and nodes (areas of cancellation). This is true of each dimension. The fact that two of your room dimensions are so close compounds the problem becuase you have these generated by both pairs of walls at almost the same frequencies. I used both ASC bass traps and a Rives PARC coupled with their BARE software to tame my room with excellent results. Granted, this is an expensive solution, but one is possible. Here are a couple of helpful links:

Shadorne - I agree. Speakers can be as flat as you like, but if your room isn't, your lost without correction, be it electrical, digital or mechanical/physical.

A flat response gives everyone a chance. What you do with it from there is up to you and your room!

I have MRC bult into my processor which acts like the Tact, you choose the ms decay time and it balances it out.
