setting up new room

Hey, this site is great,ive been lurking here for some time now. I've finally got a new room to dedicate to mixing and have a general idea of how i want to set up. Id like to spend up to $1000 to make things a little more legit acousticly. I whipped up this MS paint masterpiece. Ceiling is 8' My question, starting w/ a $1000 budget, which absorbtion/diffusion issues are best to address first? Also, what type of an effect do you think the "Entrance Way" area of this room have on the mix postition. I know when i stand near the right back corner theres much higher low frequency peaks than when i stand on the opposing side near the entrance way. This is also a rented property, so "low impact" solutions are best. Thanks a million for the advice a head of time, the favor will surley be returned w/ a site donation. Thanks, Darin P.S. I have Dynaudio BM15ps, the woofer and tweeters are off set abit, thats why my axis looks that way, ive lined up w/ the tweeters, do you think this is a good approach?

Upon further reading ive also grown curious how my closet space may be effecting low frequencies, the closet doors are just sliding mirrors. How i might be able to use this space for bass trapping, is symmetry important for bass trapping ??? any Ideas?? Thnx, darin

How i might be able to use this space for bass trapping, is symmetry important for bass trapping ???

yes - that was my first thought and no bass trapping doesn't require symmetry. Rip the doors off an hang a curtain over the front. cheers john

cool, thanks. Anyone care to elaborate on the deatils of what i might put in there and how much given the size of my room? Or should i just hang a heavy curtain in the doorways of the closets? should i utilize some of both the side AND back closet space for this? thnx, darin
