Hi all, new to the forum. Any and all help is appreciated. I started to fill out the room analysis form, but it looks like here is a better place to start based on the disclaimer at the bottom of the page.

Info from my room analysis form:

W: 9ft 3.5in H: 8ft L: 12ft 9in
Floor type: Laminate with underlayment
Walls/ceiling: drywall – ceiling is popcorn style
Average listening levels: 75-85db C-weighted slow response based on iPhone app
Number and diameter of speakers: Two monitors with 5 in. low/mid drivers (41w) and 1 in. tweeters (41w). One 10 in. down firing studio sub woofer (200w). Crossover at 80Hz.
Additional room features: Window behind monitors at front wall. 59″Hx47″W with loose curtains in front of window. Closet at rear of room. 6’4.5″Wx2’8.25″Dx8’H. Closet opening is 5’11’Wx6’8″H. Closet can be emptied and have bass absorption built into it. Room is for mixing and possibly some mastering. I have built an RFZ with 3″ Safe n Sound rockwool panels.
Average time spent in room: 5-10 hours per week or less.
Budget for treatment: Less than $2000 – Looking to DIY and am capable.

Ok, hopefully I can stimulate some discussion here.

I understand my room is technically too small, but it will have to do. I have watched the Sam Small videos as well as many of the others. I am reading the e-books as well.

I know I need to focus on the low end. So how many absorbers do I need, of what size, and where?

A, Build 8 of the BDA units. Place 4 on the front wall and 4 on the rear. You will need our carbon technology for your BDA units.

Thank you for the response. I assume I would need the broadband version, is that correct? Do you recommend any other treatment for the room outside of the bass absorption ?

Your help is very much appreciated as well as your videos and forum.

Thanks, Dave

D, Yes, the BDA DIY unit is the same performance as our ACDA – 10 unit if you use the carbon for the inside fill material and foam face. Sidewall absorption can be achieved using our foam technology.

I saw somewhere on your website that you are not selling the carbon for DIY any more.
Are you still selling the carbon?

W, We still sell the carbon for DIY but in limited situations. The smallest order is 4 BDA units which will take 200 lbs. We no longer sell for 1, 2, 3 units.
