I've tried adjusting (setting EQ and crossover points) my systems in the past using music CDs, but because the sound is consatntly changing, and because every CD or sound source for that matter has a completely different sound, it's impossible to accurately tune your system in this fashion. What do you guys use to tune your systems? I obviously don't have a spectrum analyzer, but I would think there has got to be some type of a setup CD available specifically made for system tuning. What do the guys who compete use?
