Could an acoustic cloak improve a sound system

I just saw this blog post and it got me to thinking about how an acoustic cloak could be used in a stereo setting. You can read the original article here but the details are pay walled. Audio does not transmit to what is under the cloak, supposedly. I am sure this is frequency dependent but I am unwilling to pay to get the details. So how could we use this in our setups? My first idea would be to possibly back your listening position with a wall of them to prevent reflections from the back wall. I am sure some audio would diffract around the edges but it would be at a greatly diminished level. I also wonder if you could put one behind a speaker driver in a speaker enclosure. It would prevent reflections inside the box from coming back through the speaker or interacting with the cone.

I wish that they would post the design files so that I could make my own.

This is another in the new meta-materials concepts. Yes, these things are very very frequency dependent and usually angle dependent. Wait a few years. If anyone makes something that actually works, the ideas will be published in patent and trade mags, not in blogs asking for money.

Hint, reflections inside boxes are already not a problem if you know how to build boxes.

Oh I know how to build an enclosure that minimizes reflections but having something you could just bolt behind the speaker would be nice.

Honestly I have real doubts that this technology will ever work beyond a small scale. I guess that is because I don't understand the science behind the technology yet.

Just stick on a block of OC compressed FG about 6 inches thick. I can see the attraction to the maker-bot crowd. It would sure be slick! I just wish I had a printer to print baffle panels with integral wave guides and isolation mount points
