Waveguides, Acoustics and Speaker Design with Dr. Earl Geddes 

GREAT to see you again, Earl!! And THANK YOU Jason! Earl changed my life too. - Duke

Always enjoy hearing Earl talk. Interviewer could have been more casual conversational. Earl is a trove of knowledge. So many questions I'd love to ask him.

More people should know of Earl's work and contributions to audio reproduction. Thanks to both Jason and Earl for taking the time to produce and share this conversation. 👍

Great interview. I wish the "thd+n" obsessed crowd would read more of his work. Thanks a bunch for putting out this conversation!

Many thanks for this and to Earl for sharing so much of his knowledge.

Thank you both for this interview.

Great job, Jason. I am contemplating using Duke's Swarm, a Geddes-inspired multi-sub setup. Earl has always been at the leading edge.

A very interesting interview and well done! Wish I had a chance to listen to one of the Gedde designs, but probably not possible here in Norway

Got 3 SQL 12s that I'm wanting to run sealed but getting a bigger vehicle now. I'm thinking 1ft3 each and use the rest of the 13 total as a waveguide, like a 3rd order loading onto hatch.

Nice.

He did NOT “invent the waveguide for sound” 🙄🙄🙄. Lord Rayleigh published an entire book in 1897 called the “Theory of Sound” ON WAVEGUIDES. Nobody knows wtf he’s talking about. Packard wrote a paper in *1984* discussing the repeated rediscovery of waveguides in the 1930s. It was not *this guy* just like it wasn’t this guy who first used more than one subwoofer, which has been done in pro audio for decades 🙄🙄🙄. All he seems focused on is overblowing his contributions and pimping his patents on DIY forums.
