If the 703 has an open backing (such as a frame, with the 703 covered with fabric on both flat surfaces), and the panel is spaced a few inches away from the wall, you will have twice the absorption area. When you mount flush to the wall, or put a solid backing on the panels, you are giving away half the panel's effectiveness potential. Just a thought. ATS puts their panels in a wooden slat frame much like a bedding frame, so that both flat surfaces are absorptive.

If you spaced the panel several feet off the wall you could would likely get some effect from both sides but not at a spacing of a few inches. That kind of spacing should help improve the low frequency absorption the panel provides but it has nothing to do with increasing, much less doubling, the effective surface area and I cannot find where ATS makes any such claim. And unless you are referencing some other ATS Acoustics, they clearly state on their web site (
http://www.atsacoustics.com/) that their standard acoustical panels, which are apparently offered only in 2" and 4" thicknesses, have a solid 1/4" wood back panel. You can order the 4" thick panels without the wood back but it is not an option on the 2" thick panels. Are you maybe thinking of some other manufacturer?
