There are many things I like about mahgister. Ones that come to mind:1) he readily admits when he makes a mistake or give the wrong impression, something many of us could be way better at including myself2) he does it his way which is most unique ...

I will report back here when I read something that is actually constructive or useful relating to the specific topic at hand. It ain’t happening. Half baked theories don’t cut it. Bye!

Download a sound level meter app like db on your smartphone, and stream some whitenoise (available on Spotify, elsewhere).Then turn the sub level up and play with the crossover control. adjust level up and down until flattest in the bass region. T...

maghister, Someone proposed it be measured. That is how to do it. You emotions are getting the best of you. You seem to take any questions about these things as a personal attack. You know they are not. Merely discussion to get to the facts....ie ...

Regarding measurement Schumann Resonance, according to Wikipedia article on "Schumann Resonance":" Measurements[edit]Today Schumann resonances are recorded at many separate research stations around the world. The sensors used to measure Schumann ...

Well, that doesn’t sell me but thanks for answering the question. Cheers!

Yes thanks for that we know people are free to buy whatever they want.Imagine if NASA relied on incomplete data or hearsay to land that rover rather than understanding every detail of what was involved to make it work to the nth degree.I know peop...
