very interesting thread re: cone material

I'm a guy who can kick back in a room full of lawyers, but if they were MDs, engineers or scientists I would soon get glassy-eyed.  I can hang with theory disguised with some homespun f'rinstances, but I've got a long way to go before I can hang with the conversations in some of those diyaudio threads.  But I know it would do me well because I'm about to start working on a center channel myself.

DYohn brought some speaker design software to the table the other day, and I've started trying it out.  I did a short search this morning and so far I'm going to check out (using these programs) these Dayton 6" mids with this Dayton silk tweeter in a MTM arrangement.  I'm not sure what exactly the tweets are, but I'm going to try for a smooth transition from center channel to the main mids.  My mains have these mids which I pictured a while ago on this forum.  But I'll continue to check out those interesting threads you bring up, kfr01!

I've been lucky with what I've put together so far...

"But I've talked long enough about myself.....What do YOU think of me?"    lol

Thanks, dude.  (See what I'm sayin' about lawyers?)  I'm going by the FRD tools guide to start off with.  Have to say I haven't accomplished much yet.  My learning curve wouldn't let a marble gain momentum!

Haha, awesome find.  I was reading that a while ago, and totally forgot about it.  I will have to get back in there where I left off.

I always enjoy reading my boss' posts as they are always VERY informative.  That and reading them allows me to absorb the material much better.  I ask him questions all the time at work, but have to re-ask the same ones a lot of the time because it just doesn't absorb completely.  It's not that he's a bad teach, because as you can see he is great at putting things into more laymens terms.  But I'm just a visual learner.  I learn best when he has a dry-erase board nearby.

BTW, if you want to see some other neat posts/threads, here's some links:

http://caraudiotalk.com/forum/index.php?s=4de9afcd98c70416a6b9e89a34dfdd4c&showtopic=2384  This link has one of the best description of not only what theile/small  parameters are, but also how they inter-relate to one another.  It is a great way to understand what changes when you add more mass to a cone, or stiffen the suspension, etc.  Of course there is also a great deal more about speakers as well.  I really enjoyed that thread.

http://www.carsound.com/cgi-bin/UBB_CGI/ultimatebb.cgi?ubb=get_topic;f=1;t=021545;p=1  Here's a debate he was in that brought about our "Car Audio Cabling" tech paper.  If you want to know about all about how noise radiates into your system, then this is the everst of information for you.

http://forum.soundillusions.net/article.php?a=223  I posted this not too long ago as a seperate thread.  This is a question/answer chalkboard where Dan answers questions on an online magazine.  There is some great information on material selection in speaker design, as well as some good pointers on crossover design. 

From there I just recommend searching for his name on different forums.  I have found a wealth of information that way.

When the arguments involve him, I usually know who is right and who is wrong even before reading the arguments.  I have yet to see him be wrong in these arguments because he won't say it if he isn't sure.  And when the debate gets really fueled and they just won't listen, he will go get our Chief Technical Officer, Dr. David Hyre and he will school them.  I saw this happen once in a discussion where Dan Wiggins and Mark Seaton (Servodrive) were arguing with Richard Clark (Car Sound writer)  about how mass doesn't effect the transient response of the driver.  That was an incredible thread over at the Car Sound forum that unfortunately got deleted (I wonder why).
