Echo Absorber 2″ Natural Blend Acoustic Panels

Our Echo Absorber line of products delivers excellent noise reduction across the entire frequency spectrum. Offering flexible installation options, the 2” thick, 2’ by 4’ configuration is one of our best-sellers for home and commercial use. Use it to soundproof a recording studio, home theater room, office, classroom or any other space.

The Natural Choice

Our natural blend Echo Absorber panels are VOC-free and made from 80% recycled cotton. As a result, they’re both good for the environment and Class A-rated for installation in areas where building code fire regulations prohibit the use of a synthetic product.

Echo Absorber™ panels can be mounted on any flat surface, where they will absorb unwanted reverberations and other noise. They can also be installed inside a wall to keep outside sounds from bleeding into a space. Because they’re made from dense cotton fibers, our natural blend Echo Absorber™ panels are also effective at trapping heat and can improve overall insulation for a more comfortable space.

Engineered for Long-Term Performance

2” thick natural blend echo absorbing panels may be one of our more economical soundproofing options, but that doesn’t mean they can’t be counted on for long-term performance. Our products are fungus-, mold- and mildew-resistant, and durable enough to resist tearing, even in high-traffic environments.

The times I talked with you on the telephone and corresponded through email you have been very helpful and efficient. I would highly recommend to anyone!

– S. Cimino, PA

I have emailed a lot of different manufactures and I have to say your customer service is head and shoulders above all of them. I emailed your company at about 9pm my time and when I woke up the next morning you had already answered my question and then the follow up was a few hours later. I am impressed. Thanks a lot for the quick turn around!

– E. Gustafson, NV

I just wanted to send a quick thank you for your rapid response and helpfulness. I very much appreciated it. You have been responsive in every way all through the process. It has been a pleasure doing business with you and your company.

– T. Alexander, CA

I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.

I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.

– Mike
