reducing a specific frequency from a specific area?

[brianhood]

My new control room is set up in a specific way according to my window, so i can't change the spot in my room where i set up.

My problem is that there is a noticeably large boost in the 135-140hz range where i sit. That is unacceptable for my mixing area. This doesn't happen anywhere else in the room, so what are some ways to reduce or eliminate such a specific frequency in a specific spot?

acoustic treatment

baaaaaaaaaas traps.
and lots of them.
run a test tone and move them round your room once youve built them to see where position wise gives the most improvement.

Could try some kind of tuned absorber, there's quite a few designs around that you could DIY if your handy with a saw

As everyone else has said, try some bass traps. I picked up two of the Auralex LENRDs for the corner nearest my monitoring area and they seemed to help tighten low frequencies up a bit. Also, you might look into some of the other absorption products to cover the spill below what the bass traps cover. Something like the VENUS or similar. And possibly something to cover a bit above what the LENRDs cover as well. Auralex is the only company I have any real experience with, but there are others also.

You could use an EQ if you've got a boost problem. If you've got a null problem EQ won't work.

Although acoustic treatment would be more beneficial, obviously EQ is free (but can be annoying.. I don't think there'd be an easier way than putting it on the master bus and then remembering to take it off when you bounce).

seems very afro-engineered, but sounds like it would work decently until i can get the problem with my room sorted.
my problem is that my schedule is too full to deal with this stuff right now

Basstraps + http://www.thomann.de/se/behringer_fbq_2496_feedbackdes.htm (with a ECM800) is my sollution. I have used the FBQ2496 for a year now and I havn't had any problems so far.

+1. I think it would be better (if you HAVE to run an EQ) to run the EQ in line (i.e. hardware) with your monitors rather than strapping an EQ plug on your master bus.

A hardware EQ would be a decent TEMPORARY solution, but definitely not long term!! If you do have to use an EQ on your master buss, just be sure to ditch it before you do any bounces!!!
