Waveguides, Acoustics and Speaker Design with Dr. Earl Geddes

[@dl6519]

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

[@shawnl7966]

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. 👍

Thank you for the comments. I agree and this is one of the reasons this podcast exists. 😀

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

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

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

never heard of him. I heard of tom holman THX sound system.

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.

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.

[@TheIntellectualPeoplePodcast]

I don't believe anyone said that he did.

[@conduit242]

@@TheIntellectualPeoplePodcast He said exactly “when I developed the concept of waveguides” at 11:53 and he also said he’s the first person to use the term “acoustically”. He’s full of it. Then he was asked at 21:35 if he came up with the concept of multiple subwoofers and he said yes.

[@TheIntellectualPeoplePodcast]

@@conduit242 You're taking what he said out of context. As for the subs, actually even Todd Welte agrees that Dr. Geddes did but didn't put it in a white paper first.

[@conduit242]

@@TheIntellectualPeoplePodcast “out of context” how? He said exactly what was stated and elaborated on it. Don’t be silly 🙄

[@conduit242]

@@TheIntellectualPeoplePodcast Multiple subs had been used for decades before the paper he didn’t write. Deny the use of multiple subs for cardioid and hyper cardioid setups please.
