Hello Dennis, just purchased the BDA plans. I’m one of those “lucky” guys in the red zone (15x12x8) and I don’t see myself in a 14′ high room anytime soon. It REALLY doesn’t make sense to me when I see corner bass traps for sale that weigh just 15 pounds. Your plans (and the ACDA units of course) seem just the ticket. I have some questions.

I was surprised to see the plans include the 2″ foam in the build. I was under the impression that these were going to use the carbon filters. You state that we can get 75% of the performance by buiilding this way. Is that because of using the acoustic foam instead of the carbon?

It also seems that others have been sold the carbon filters yet I don’t see them for sale. Are they available for sale? If so, how much do they cost? I’m thinking of building two units to start with. I’m here in Los Angeles.

Thanks for the great info, including the videos , that you make available to all of us novices. I’ve been enjoying the learning experience so far.

Ok, I just went to this page referenced in the plans:
https://www.acousticfields.com…..kit-guide/

In that page one of my questions is answered:
“The only difference between this and our production units is that the production units have the carbon filters inside them.”

I still want to know if the carbon is available for sale and now I have an additional question. That page mentions a “DIY Bass Absorber BDA kit”. Is that no longer for sale? That would be epic! I’m not looking forward to cutting those dado cuts myself.

Z, The carbon technology replaces the foam inside the cabinet. It is 350 / BDA unit. The foam face is 75.00. Drawings are provided for the carbon filter build upon carbon purchase.
