DIY Bass Absorber (BDA) Build Plans - www.AcousticFields.com 

We installed Acoustic Fields 6xACDA10,2XACDA12 absorbers and custom made 3xQRD17 diffusers with ACDA12 basses and our control room never sounded so good, been doing it here for 25years,do yourself a favor and contact Dennis that will be the best investment you will ever make for your business.

you do great pedagogical work. thanks for this and many ther vids I looked. I understand now MORE!

I would love your take on golden ratio / Bucky Fuller dome built studios. Especially working in Northwestern Pine for the blank canvas room if you will.

Hey Dennis, assuming that the plans are obviously NOT blue prints, do they come with math formulas to calculate the required dimensions, density etcetc so that we can layout and build the most effective/suitable BDAs to our needs? Thanks!

Hi Dennis i'm just about to build your BDAs, but it the instructions call for Alder, Basswood and MDF and doesn't specify which wood is for which panel. The cut sheet lists the two front panels as "MDF" so i assumed your cabinet must be the alder or basswood? But in this video here you're saying the cabinet the MDF... Please clarify.

Hi! If I build the BDA-s the standard height 57", is it wise to raise them up from the floor a little to get more absorption above ear level, or not. Thank You.

Hi, I bought the Bass absorber plans and there is 15 mm mdf used as one of the front walls. I didn't find 15 mm mdf in my area, can I use 16 mm instead? Or 12 mm - that is closer to the imperial variant 1/2 inch.

I have issues at 500hz also. Is their a way to extend the range up to 500 Hz?

Is it the cabinet sealed by the wall diaphgrams? Is the air inside actin acting like damping material?Thanks. Giuseppe from Italy.

What is the fill material used in these? Would I be able to source the internal fill material here in the uk?

Good Vid Dennis, but why 30Hz and not 27.5 Hz (Low "A") ?

"You're not going to be using carbon in the BDA." What if I buy carbon pellets online?

cool

Apartments and Condos and Boom Cars. Low Frequency travels for miles let me tell you me. Animals in Oceans and on land use it to communicate over long distances.
