Welcome comments from the gang.

Simple and very effective demo. Nicely done!

Thanks, Craig.

Thank you for posting this Stephen. Just for fun, I downloaded the seismograph app, fired it up and placed my phone on my components. I played some serious funky music. At 85db my speakers showed just the tiniest amount, the rest of the components were just flat.

I wonder if the the app is faulty or my components happen to be isolated pretty well.

Thanks Stephen...those EVP’s sure look like they are worth their weight in gold. :thumbsup::thumbsup:

Yes, I would expect everyone's system will be a little bit different.

Yes, they work well. And keep in mind the ones I was using, the medium density EVPs, were not even the right density for the weight of the iPhone.

YT shows the video as unavailable.

Yep, I have to go back and mute the sound to meet YT's copyright requirements.

Craig,
