@tomic601 ,
Plugged in my two 7.83 HZ Shumann Ultra Low Frequency Pulse Generators. Total cost for these plus two USB chargers, two 3ft USB extension cables = under $35.00.
Instantly noticeable was the center stage seemed not as up front and there is an ease of the entire presentation. No decrease in resolution or dynamics. Put 4 small pieces of Blu-Tack on each corner and mounted to the top of my Ushers. Recommended mounting height is 5’.
I already use similar products to good effect... Synergistic FEQ and Bybee iQSE.
