Echo Busters Echo Buster 18x48x3 (5 units)

I have for sale (5) 18" wide x 48" long 3" deep Echo Busters. These sold new for $285 each.
Unfortunatly, I do not have shipping boxes large enough for these so customer pick up is required. The fabric on front ,sides and back looks to be very good.

Below is a copy of the Stereophile review.

"The Echo Buster absorber panel might well be the first Buster acoustic treatment that most people try, assuming that they're not attacking evils as pernicious as the bass boost I had in my Albuquerque room. One of the major factors in optimizing focus and detail resolution is ensuring that the direct sound from your speakers isn't muddied by reflected sound. The physics are pretty straightforward, but the bottom line is that you've either got to get your speakers away from reflective surfaces, or damp those surfaces so that reflected high-frequency information doesn't arrive at your ears soon enough to be confused what the speakers are trying to tell you directly.
The Echo Buster is a lightweight panel absorber: a foam-filled rectangular wooden frame that can be stand free or be hung on a wall. At about 5 lbs, it's easy to handle and move around, and can be located just about anywhere. Like most foam-based absorbers, the Echo Buster's absorption increases as frequency rises, going from essentially zero effect at 125Hz to being completely absorptive above about 750Hz.
Back in Albuquerque, I had no problems with sidewall reflections in my main listening room, but I did have a reflective floor and ceiling. I ended up with a pair of Echo Busters on the ceiling, at the first reflection point, and, during listening sessions, with four more flat on the floor, midway between the speakers and my listening chair.
The effects of damping first reflections weren't nearly as large as taming my upper-bass response, but they were certainly audible. Improved image focus was probably the biggest benefit, manifesting itself most obviously in an increase in the dimensionality and tangibility—the density—of images. My notes from one installation, a system built around Thiel CS2.3 loudspeakers, refer to Rickie Lee Jones' Naked Songs (CD, Reprise 45950-2). "RLJ's image is much sharper, much more dense. It finally seems like I could walk out and put my arms around her, instead of just knowing that she's somewhere over there."
Like the Bass Busters, the Echo Busters, once installed, became a fixture in my setups. Some speakers seemed to need a bit more floor and ceiling damping. With others, leaving the floor and ceiling a bit more reflective seemed to open up the soundstage and create a bit more space above the orchestra. But rarely, if ever, did I end up with a setup that didn't incorporate some damping above and below.

The verdict: Another winner. The Echo Buster is light and easy to use, even to hang on a ceiling. And the benefits, while sometimes subtle, are always audible and worth the work. At prices ranging from $130 for the smallest model to $285 for the largest, it's definitely worth having a few Echo Busters around.

Summing Up
I'm a big fan of Echo Busters' products. I think every serious audiophile should at least try them. Whether you're wrestling with problems as big as my Albuquerque bass boost or my California fireplace, or fine-tuning image focus and soundstage air, the Busters are great tools to have at your disposal. As a reviewer who is constantly changing setups and equipment, I can't imagine doing my job without these products. And as a music-lover, now that I've heard what Echo Busters can do for a system, I never want to be without them. They get my highest recommendation."
