Ed,

Don't you like it when a plan comes together?

Don's website includes links to his major papers and details about him:

Welcome to the official website of D.B.Keele

His latest major constant beamwidth technology (CBT) paper published by AES is:

http://www.xlrtechs.com/dbkeele.com/...0Paper%205.pdf

and a picture of Don and his array:

His 2010 AES Boston presentation in January is outlined at:

AES Section Meeting Reports: Boston - January 14, 2010

The Boston viewgraphs are linked at:

http://www.linkwitzlab.com/Keele%20-...4,%202010).pdf

and video presentation at:

MobileMe

Dr. Linkwitz has some comments about CBT technology at:

Linkwitz-Links

You might chose to view the viewgraphs and video together for full impact of video and audio together.

Marshall Kay (Audio Artistry) and Don have recently worked together on a CBT array which Marshall will bring to Dayton. I'm sure that the Dayton attendees would find the CBT technology to be of great interest.

Should be a lot of fun.

Cool, it will be fun to meet him!

gainphile · 17th June 2010, 04:30 AM

I checked his homepage. What an impressive credential!

Ed LaFontaine · 23rd June 2010, 01:31 PM

Bump

This is less than 3 weeks away.

Who is going to attend?

indianajo · 24th June 2010, 02:15 PM

I see Peavey, Crown, & NTE are going to be there. I already know what their stuff sounds like. Any chance anybody is going to demo a full range speaker there? I don't need to hear anymore car trunk buzz tubes. (the competition) I'd like to see what all the noise is about. Dayton has some cool stuff to do besides a show. The music shops around here have 1. 2 woofers 2. 4 woofers 3. a 2 way speaker with a woofer and a horn.4. a Bose with a lot of little speakers pretending to be a big one. And Best Buy demos in a warehouse, which is useless. Ed, are you the guy that sells used amps in Winchester Ky? It is just a tiny bit too far from Kentuckiana to save any money on them.

Ed LaFontaine · 25th June 2010, 11:52 AM

indianajo,

There are likely to be ~30 or more pairs of speakers in the competition...home audio. I can't guess on the auto comp as I don't participate in that.

I don't sell amps. Winchester isn't far from here. I'd like to find out more about his offerings.

Pano · 25th June 2010, 12:09 PM

Well I'll be there for sure, as I am one of the speaker contest judges.

Anything you guys want me to look out for?

SunRa · 25th June 2010, 06:39 PM

Wow, those are interesting. Pano, hope you'll tell us if those line arrays are sounding anything like horns. I understand the claim is replacing them..

Ed LaFontaine · 11th July 2010, 05:02 PM

CBT is the real deal. If you get a chance to attend one of Don Keele's presentations, you should.
