Greetings. I’m in the planning stage of treating my drum room. I know I’m going to build 8 ACDA
12 cabinets to start. My first question is, how will it affect the absorption
rate if I build 4 of my cabinets 48”x96”x16” instead of the standard 30”x60”x16” cabinets..? My cabinets will be oriented with the 48” dimension as the height and the 96” dimension as the length. Secondly, how would I determine the amount of activated carbon I will need for cabinets that size..? lxwxh…? My plan is to cover the cabinets in Tolex and use speaker grill cloth to cover the foam
… will the speaker cloth be an acceptable fabric to use..? Thank you in advance for your replies.
Our 30″ w x 60″ h x 16″ ACDA -12 unit weighs 240 lbs. This produces 19 lbs. / sq / ft. density. Building the units the size you have indicated will result in a unit to heavy to manage and too dangerous to build. Stay with our production unit size. It has been field tested 14 years.
Thank you Mr. Foley, I will build the cabinets to your specs then. How about the speaker grill cloth, will that be an acceptable fabric to cover your foam …?
Be careful with products that are labeled “speaker grill cloth”. Any fabric you place across the surface area of a technology that works on air flow will restrict a percentage of that air flow. This process restricts the performance. You must choose a fabric type and company that offers fabrics with a minimum 97% air permeability rating. Use fabrics from this link: https://www.guilfordofmaine.com/acoustic. Our carbon technology for DIY projects is on a reservation system due to demand. I would recommend getting your order in 8 weeks ahead of your installation.
