....anybody...

Run some pink noise through a speaker. Hold a mic in each hand. Wear headphones and keep the volume of the two mics the same in the phones. You can do this with a 100hz tone too to get an idea of how it effects low end.

:roll:

Can't you do this yourself? Inverting the phase of just one channel? If you can't do it with a DAW or sound editing software, you could still invert the phase of one of your speakers. Or did I miss your point?

just wondering if there were some samples I could download without having to make......i just need to burn them on disc to show someone
