CPA – Ceiling Perforated Absorber
Every small room has small ceiling heights. Dimensions of 8′, 9′, and 10′ produce unwanted axial modal pressure that can exceed 10 dB or slide down into – 7 dB territory. The floor to ceiling dimension is responsible for that 60 – 75 hz. dip. It must be treated. The floor to ceiling dimensions of 8′ produce 63 hz. issues and a 9 foot comes in at 75 hz. with most room ratios today. We have two treatment surface area options. We can treat the floor or we can treat the ceiling. We must treat one. Let’s go to the ceiling.
To come up with a lighter and effective technology, we have taken our proprietary foam technology and increased the thickness to 6″. We have placed 3 of our 2″ pieces of foam inside a perforated absorber to lower the effectiveness of our foam technology down into the 65 hz. range as a lower frequency design parameter. A perforated absorber has a front plate of holes that are 1/4″ diameter and 1″ on center throughout the face of each unit. The face, foam depth, and back piece all combine to produce a 75 lb. solution to the ceiling dimension pressure issues. The CPA or ceiling perforated absorber is designed to target the problem frequency issues created by 8′ – 10′ ceiling heights which are prevalent in today’s rooms.
This perforated hole size and count coupled with our 6″ foam technology will yield absorption down to 65 hz. The CPA is 56′ w x 7″ h x 76″ l. It weighs 75 lbs and can be suspended from the ceiling surface area over the DAW. Most small rooms will require two units and numerous. paint color options are available.
