During a recent workshop, Michael Curtis asked me how it was possible for a HPF to create positive phase shift, therefore indicating an early arrival. I told him to stop asking me stupid questions and hung up the phone. Then I secretly asked Francisco Monteiro the same question and he made a video about it. This is my attempt to reproduce Francisco's results.

I love to geek out about the physics of sound. This channel focuses on the growing opportunity for live sound engineers to improve their confidence and consistency through the understanding of the principles of sound system design and optimization. My goal is to make this channel upfront and honest about my success and failure, so you can learn from both.
I am always open to suggestions and feedback so please comment on this video or contact me through my site.
