Hi, i purchased your Bda build plans, gonna build then soon, just waiting on good weather (and i needed more funds to finish everything asap). I wanted to ask you is it possible to β€œtune” or do β€œsome” mods to BDA unit to focus 30-50hz like acda12 ? I wont use carbon tho, i will use rockwool to get lower results.

P.s bda starts at 40hz so 30hz does not matter. Let says mod do work around 40-60hz or something like that

I, You need the carbon to get the rate of absorption with the ACDA -12. No mods are possible without redesign and testing.
