Hi, I really need some help sorting out bass trap positions for my mix room at home. I know its a small room but I'd still like to have a go at getting the bass working in it! So here's my plans... I took my time with these so I hope they are up to scratch.

I'm no expert so I just chucked in a few ideas... any options most welcomed

bass trap pictures are from Ethan's design page.

PICS REMOVED SO NEW PICS LOAD FASTER

I want to build all the bass traps and diffusors myself. I love DIY!

Remo - sorry I missed your post - look your room is tiny really - you can't approach it like a large room with diffusors and bass traps etc. If you build those bass traps you'll end up with a live small room. Similarly with the diffusors.... not a good idea in such a small room.

I'd look at putting in corner traps, either slots or just straight 703.
Your one advantage is the ceiling where you could easily drop a false ceiling with hanger traps throughout.

like this

you'll aslo need something to break up the parallels like some angled slots on your side walls.

Hope this helps

Cheers
John

thanks John... yeah it is a tiny room

I'll look into the construction of your corner traps. btw.. please have a look at these datasheets, are any these products similar or able to be used in lieu of "703" (which I can't seem to find here in Aus):

also, just got a couple of simple questions about your absorber design. When the plan refers to "insulation", could I use one of the above linked products?

Also what freq. range would you rear wall absorber trap effectivly cover?
thanks again..

so in short I should go for this style configuration:

thanks John, I took order of 5 sheets of 75mm semi rigid on Friday, 2400 x 1200 is BIG!!

they really smell bad so I aired them out in the sun for a while and my dog thought "hmmm, don't mind if I do...". (don't worry, I got her off there fast)

anyhow... heres my updated plan for the small mix room. I need to keep everything semi perminent as I'll be moving shortly and i want the traps/treatment to be portable (even though they will be big)! Can you tell me should I pack the areas in the front corners marked as #1 with more absorbant material like normal 3.5 or 4 fiberglass fat bats or should I leave it empty? If you've got any other suggestinos I'm all ears.

thanks,

I did try standing them up in the corners. It only made a tiny bit of difference. I put this down to the fact there was no sealed air gap behind the boards. They certainly do have effect HF though which I instantly noticed. As the units I will be building are portable I will just make them and test them in different configurations and see what works. To bad the rooms so tight. ahhh well it's not forever. Oh yeah, do you think I should fill the area #1 with rockwool/tontine etc or leave it empty?

-------------------------

sorry to hear about your Kelpie passing, must be a hugely missed member of the family.

We rescued Ellie from the RSPCA lost dogs home 2 years ago, she's getting a bit on these days but what a dog, so smart! I don't think I'd want to own a different breed after having a kelpie, she's been such a good dog! We love her!

ok ppl.. here are my semi custom non permanent bass traps! I finally got the time to make them! Let me know what you think of my handywork..

btw the sides are all 25mm MDF and the backs on the big ones are 18mm MDF.. they are also caulked air tight... I will be slotting 100mm of semi rigid fibreglass into the front of the deep bass traps (the fibreglass will be gently held in place with the lengths of dowel that run through the trap).

the skinny one is more just a frame to hold a single sheet of fibreglass...
I will be stacking the two big ones at the rear of my room and putting the skinny one at the front at head height.

Hi Remo,

Your frames look pretty good. I am moving to an inner-city apartment and a smaller room for my productions, so I am contemplating building similar traps. Where did you get your rigid boards, and how much were they in australian dollars? My interest in acoustics is very recent, due to the small square room I will be occupying in a few weeks. The things we do for a great lifestyle! What sort of treatment do you have in mind for your back corners?

sh.

any of these rigid product will suit your needs..

just look at the acoustic information and cost to choose.

small square rooms are so hard to treat dude.. good luck

I'm only putting the large frames on my back wall as there is no space for corner traps.
