Audio Industry References and Educational Resources

Hi Folks,

Here is a list of some of the industry people that I have met or learned from or both. I even met Mr. Robert Harley at Overture Audio in Wilmington, DE a few years ago.

There is also a list of books and papers that I have purchased and read and read again and again.

Mr. Alan Hulsebus, Lead Engineer and Designer
ORCA Design and Manufacturing Corp.

REF: Alan is my speaker system and enclosure design mentor since 2000. He has taught me so much. He has seen drawings of a few of my designs over the years and commented very favorably on their appearance, cabinet shapes and structural aspects, implementation of drivers, and creativity while applying what he taught me. He is truly one of the nicest and most patient and helpful persons that I have ever gotten acquainted with and is extremely talented.

Mr. Mark Gilmore, Owner and Designer
Gilmore Audio

REF: Mark reviewed and commented favorably on one of my designs from having sent him the drawings in 2005.

Mr. Siegfried Linkwitz, Engineer and Designer
Linkwitz Lab

REF: Mr. Linkwitz guided and advised me in 2005 through E mails regarding dipole, open baffle speakers.

Mr. Mark Nazar, Engineer
Boston Acoustics Inc., Apogee Acoustics

REF: Mark, and the late Jason Bloom, escorted me on my tour of Apogee Acoustics in September of 1996 for research for my book on ribbon speaker technology and manufacturing techniques. He also provided some assistance and guidance in upgrading the crossovers in my Boston Acoustics CR-9 book shelf speakers in 2006. I used Solen cap’s, Goertz air core copper foil inductors, and Mills non-inductive resistors. They worked the first time and ever since have sounded great. What a difference they made in extension, bass impact, clarity, imaging, you name it.

Mr. David Berman, President
Soliloquy Loudspeaker Company

REF: I met and interviewed with David in January of 2004 just before starting at a certain other audio component manufacturer. I told him of my desire to get into home speaker system and enclosure design and testing. As we talked and went through my drawings in my portfolio, he offered me an independent contractor position to recreate all of their cabinet drawings into Autocad using a lap top computer that would be assigned to me on an hourly or per speaker basis. Sadly, between the company having certain limitations at the time and getting hired at the other company shortly there after, and the conflict of interest it became since I was hired partially to do loudspeaker system and enclosure design, the position never came to be. David impressed me as being very amicable and a gentleman.

Mr. Chad Lundstrom, Store Owner
Audio Designs

REF: Chad is the owner of a terrifically done store that was associated with where I was working at the time in February of 2004. I helped him set up, position, and select several Focal / JM Lab and Legacy Audio speakers for better sound and performance and to mate well with the integrated amplifier that he had on display from the company I was employed at. I also assisted a customer with how to use his existing Bryston two channel amplifier with a new 5 five channel amplifier (also of the company that I was employed at) so that he would not have to sell the Bryston that he liked very much.

Here is a list of the books and other sources that I have read several times, studied in depth, and used as references for my designs and attribute as major contributors to my knowledge, understanding, and abilities.
