New book on "Audio, Acoustics and Perception"


Dr. Earl Geddes is writing a book aimed at folks like us - namely, hard-core audio hobbyists who do not have an advanced technical background. He's posting the chapters on his website so that we can read along as he writes the book. The first chapter is online now at:

Dr. Geddes is a professional loudspeaker industry consultant, has an extensive background in acoustics (in particular small-room acoustics), holds several patents in the field of audio, is the inventor of the oblate spheroid waveguide, and has done extensive original research into psychoacoustics and perception. I have associated with Dr. Geddes somewhat over the past couple of years, and have learned a great deal from him. I'm very excited that now he's offering all he's taught me and more free of charge, at least up until he finishes writing the book and publishes the hard copy.

Directivity speakers that VMPS will be showing at the CES quite interesting. How about a 180 degree power response from 280hz on up? This new waveguide technology is patent pending and is novel.
The planar and ribbon drivers of Vmps speakers will now have 180 degrees of dispersion. This will be measured and posted at the Vmps forum at audiocircle. The tests will be conducted by a known engineer and audio journalist. I'll add that I've become a dealer for VMPS in the Northwest so caveat emptor. For those of you who know Brian you also know he's not one to hype. First reports are very interesting indeed. Cheers
