Back in 2011, JL Audio did a training presentation known as The School Of Sound at Spring Break Nationals in Daytona Beach, FL. The class was about 3.5 hours but it covers a lot of information. The presenters (Steve Turrisi and Jason Sayen) keep the information enjoyable and engaging. It is a long video, but we share it with you if you want to watch it.
Here is a link to the video:
The handout used is provided here as well.
Some of the product referred to in the video and the handout are no longer available. Additionally, many of our newer items are not listed in some of the charts. Some generic charts are provided here, but if you need specific information, please send us a message at firstname.lastname@example.org.
Feedback is always appreciated.
