I just want to clarify my comments on how the Synergistic Research (SR) Atmosphere/FEQ work. I still believe SR is manipulating the Schumann Resonance based on my previous experience with the Acoustic Revive and my own using/listening to their products. However, it should be made clear SR says they are using a multi-wave radio frequency (RF) generator not a Schumann Resonance generator. Whatever the case may be, I think these processes go in-hand which SR seems to allude to with this comment in their explanation of what's going on:
"In a nutshell, we discovered that during the day ambient RF is stronger while the Earth’s Schumann Resonance is weaker in relation to overpowering solar and man-made radio frequencies."
I've received emails from a fellow Audiogoner who wanted more and more details. At this point, I should bow-out and simply refer people to SR for further explanation. Thanks!
