If anyone is interested in learning about SQ and how to set up a home or car system for accurate reproduction I highly recommend this class. It is right after Spring Break Nationals, next week in Daytona. Also, if you don't want to get quite that deep into it I recommend the JBL Engineered Mayhem tour. They cover a lot of material in a half day for much less money than you would pay an installer or any other pro-competitor.
