I'm in a rush to get to work, but as promised here is the first contact I received from Mark on the proposed SQ seminar. Here's the email:
Hi David,
Robert Ables called me this afternoon and told me about the DIYMA meet and greet that you put together, and some of the topics you discussed. I read through the threads that Robert forwarded to me also. It sounds like you have a really enthusiastic group going. I'll definitely have to start participating in some of the forum discussions.
Robert and I also discussed the Advanced Sound Quality seminars that I teach several times a year, and that it might be something that the DIYMA group would be interested in attending. I have been planning at least one prior to the T-Town Invitational, and if it makes sense to have it in the DFW area, and there are enough people that would attend, we can arrange for that possibility.
Attached is a sumary of the possible topics that can be covered in the class. It can be a one, two, or three day class, depending on what the attendees want to cover, and how much time they want to spend with hands-on practice and demonstrations. The classes I have put together are very practical, with only enough theory to explain the topics. There are numerous demonstrations and practice sessions also. We get very intensive, an ddig as deep as anyone wants to into each topic. No SQ related topic is out of bounds. We can cover anything you want to discuss. Handout notes are also included, and I ahve many different test CD's, tools, and book information available too.
And, I don't do PowerPoint presentations in these SQ classes... They bore me as much or more than anyone else...
If we can organize a class sometime between now and Labor Day weekend before the Tulsa event, we can also set up a tweak and tune session at my facility in Tulsa a day before the show (Thursday or Friday) so that anyone that attends the class can get their system really dialed in for the event.
If you're interrested, and think some of the others in the group would be, let me know, and we can get a class put together. I promise you, it would be a lot of fun, and you would learn more about car audio sound quality in two days than you can from any other source.
Give me a call any time.
Thanks!
Mark Eldridge
There is also a menu of the topics that could be covered but I can't copy it till I get back and upgrade my Office.

Advanced Sound Quality Workshop Topics
- This is a very abbreviated list of topics that can be covered in a one to three day course.
- Additional, more advanced topics (not listed here) are also available for subsequent courses.
- The times listed with each topic is an average time required to adequately cover each, with some hands-
on practice time included. The actual time needed to cover each will vary depending on how much class
time can be dedicated to it, the coverage detail desired, and the amount of hands-on practice is desired.
- One, two, or three day courses can be created by choosing from the listed topics.

Other useful tools – oscilloscope, Radio Shack amplifier, DVM, etc.
Books, Articles, the Internet, and other sources of “information”
Your Ears - Definitely the most important and effective tool in your arsenal!!!!!

This is a RARE,RARE opportunity that is being offered here and I hope many of you will be able to avail yourself of this. Please post if you are interested, and if enough people show interest we can go forward. This won't be a ragtag put together deal like at my house. We are talking professionals here with more knowledge of our sport than you could hope to gather anywhere else. It's not cheap, but then neither is what is being offered. Foos
