Hello i live in a Trinidad last island in the caribbean, my studio room is 25feet L X 10 Feet W x 9 Feet H and i have a 45hz bump at around +6db and a reverb time at 350ms when played at 70db, i also have a room mode on my right hand side of my listening desk of +4db at 117 hz… my room is treated with rock wool and foam … i would of love to buy 2 of your ACDA but the cost of one for me is more than 5 months pay converting the $ and worst yet one is 200+ lbs would in my country would be paying more in taxes than the unit itself… so that is like 2 years of savings to get just 2… so my question is there any option for affordable low frequency absorption at a cheaper rate even as a DIY project where i can get all the materials from my country itself?

Hi Ladraz, You can build the BDA unit from materials available in your area. You will need a minimum of eight units for your room size and volume. Here is the BDA link:…..-absorber/
