Bass Trap Inquiry

Post by (chuckie) »

I have built 2 x 8 foot high tube traps.
They are placed in the corners of the front wall, in front of me, behind my mix desk. I am using Yorkville's YSM1p's.

They made a difference initially and i was happy with the balance of sound i was getting at my mix position.

Now, i have 'upgraded' to a smaller desk to get some more room for my gear rack, and also have chosen to move my monitors in closer > < now my equilateral triangle is smaller, and i dont have to sit back as far, which i thought was a better idea.

Now i run into some bass problems which make me un happy. At my mix position im in a big lack of bass, if i stand up at my mix position so my ears are above the speakers, i get a nice bass response, if i move to the back of the room , very sweet bass response, and of course the back corners. I seem to have MORE bass higher in the room, (top corners, near the ceiling) rather than in the lower corners/floor end.

Could someone throw me a few suggestions, maybe theres some science behind this? should the bass traps be in the back corners? have i trapped TOO MUCH bass?

Thanks in advance.

Saw your identical post over on HR, and the unbelievably cryptic answer - I'm almost out of time right now, but if you can post your EXACT dimensions I will work up a map of your room showing you good and bad locations for speakers, your head, etc -

I'll need all three dimensions of the room, then exact measurements of where your head and speakers are, relative to the walls and each other - please include speaker height (center of woofer), ceiling height (if sloped ceiling, height at each end and height where speakers are), head height from floor and ceiling, at the mix position - if there are any pieces of furniture taller than about 32", add that info. Also any acoustic treatment you may have already done -

Once I have that info I'll do a workup, and post it here along with links to pertinent tools so you can do your own later if you like... Steve
