The Acoustic Revive devices you mentioned may improve the sound but will not "make the walls disappear". The Acoustic System Resonators properly deployed can make the walls disappear like nothing else I've encountered. "Properly deployed" is key. In my experience it takes extensive experimentation with placement to achieve what you are seeking, and small differences in placement can make a big difference in the outcome. If Frank Tchang or one of his disciples is placing them for you good results can come quickly. On your own it may take many hours of tweaking.

Here’s my take on the Schumann frequency 7.83 Hz. I have just come off a long experiment using one of the Isochronic Schumann tones available on YouTube, an acoustic version of the frequency, as opposed to most other generators which produce an electromagnet wave 7.83 Hz., e.g., Acoustic Revive RR-77, RR-777, etc.
After all was said and done I got superb results playing the acoustic 7.83 Hz tone streamed from YouTube for 20 minutes prior to a listening session, I also keep the Schumann signal playing from my iPad placed 3 feet from me while listening.
What this does for the sound is very remarkable. Through headphones the soundstage is very deep and wide, way outside the confines of my headphones, as if I was listening to electrostatic speakers placed six feet in front of me. on certain material like some Dead Can Dance CDs and live recording soundstage can be as deep a ten or twenty feet or more. On headphones. There is much better bass performance, better tonality, dynamics, *realism* and air. I got to this point by isolating the iPad at all times including initial warm up using a spring based isolator circa 2 Hz.
What I think is happening is the Schumann frequency - whether it’s EM or acoustic - synchronizes the neurons in the brain and synchronizes the right and left hemispheres of the brain. The reason these generators work is probably because the real Schumann frequency, the one that is located in the trough between the Earth Surface and upper atmosphere has been reduced in strength by modern industry and technology, etc. since early man had evolved using Schumann frequency for better brain function, e.g., navigation, sensory perception, information processing, focus, these function were reduced. Now they can be restored using these generators. The signal strength of the real Schumann frequency is now on the order of microvolts, maybe a few hundred, I’m guessing it was considerably higher at some point in the 1800s.
