Welcome to the Klipsch forum.....hope you stick around.
This hobby began in 1966, when I figured out how to disable my dads stereo by swapping out the driver tubes for RF tubes. He used to like to blast the stereo during the school week til 1 in the morning.
my first crossover network project came in 1972.
my first DIY khorns came in 1986. I built as set of khorns using 18inch drivers, enclosed backs, and used them at an air force base in Germany during all army day.
