Cost effective Schumann Resonator


After reading about the Acoustic Revive unit, I was looking on Ebay and found a Schumann Resonator for $175 (plus $20 for a very nice plexiglass case). It's model designation is Chartres Mk.2. It is made by a fellow named David in Indonesia. He was a pleasure to deal with, start to finish. The unit arrived in about 10 days. The fit and finish was reassuring. It is a circuit board with good quality components mounted between two sheets of well cut and finished plexiglass.
I have read, and failed to understand a lot that has been written about Schumann resonators, but I am willing to. Suspend disbelief and try a tweak that a lot of folks say works. My initial reaction on hooking up the resonator was disbelief. Sound stage and localization were noticeably better. I had to disconnect and reconnect the unit several times to convince myself that I wasn't fooling myself. Mechanism of action be hanged, it made a very positive difference in my system. This finding was confirmed my moving it to a second system where, again, spatial information seemed much improved.
I am very happy with this purchase. Results rule!

So, that's how it works, it relaxes you? Not the RFI/EMI thing that Acoustic Revive used to explain? Have they updated their explanation too?
I've been listening to the original RR-77 for many years and it does do everything the manufacturer claims and I've too have felt "relaxed" during and after listening sessions.
Both the AR888 and the Fleabay version (I recommend the Chartres Resonator Mk2 version for better resolution and detail, esp with +12V LPS, there are tons of suppliers for that on Fleabay as well).
Positioning the AR-888 or alternative product is key, you need to experiment. I recommend the first one in the middle between the speakers, between 5ft and 6ft, the second one either on the back wall or on the side wall at the reflexion point (the same location you would put an acoustic panel). 
This tweak has no downside: it does not change the soundstage or induce imbalance but, because of how it functions, "cleans" the air in your listening room, resulting in more details and increased clarity.  Other tweaks or cables can have side effects. IME one of the best tweaks!
They sell a Schumann frequency CD all over the Internet probably Amazon, too, that will produce a 7.83 Hz acoustic tone in the room through any speakers, even bookshelf speakers. Of course the Acoustic Revive device and other similar units produce an electromagnetic wave. An electromagnetic wave, not to be confused with RFI or EMI or even a shield against RFI or EMI. An electromagnetic wave with a wavelength of 26,000 miles. We can get into how such a long wavelength wave fits into the room later. Lol

I also use and enjoy these Schumann frequency generators. As you pointed out positioning is a key to their being used with success. Too low in placement, and the sound is fuzzy with increased low frequencies. As the unit is elevated from the floor the focus and clarity improve. I have one between the speakers (my horn system), and one  behind the listener, both 
at a height of 6' 8" off the floor. Six inches of height change made all the difference between being an improvement versus just a change in sound.

I also have one installed inside the car - next to the interior ceiling and 1 foot behind the driver and passenger seats. Same effect- instruments have better focus. Confirmed by independent passengers who have no idea what I am turning on and off.

The ultimate version of this technology is the Synergistic Research Atmosphere Unit. It generates more than one frequency  and pulse duration.  This model is currently installed in my Terasonic speaker system, and allows you to synchronize the sound of each recording with the rooms acoustics. Adjusted easily using an I Pad as a remote control.

It allows each  recording to be heard at it's best. Expensive but to me, worth it.
