Real Time Analyzer usage is very popular in car audio. Just wondering why it isn't so popular with the home crowd. It would seem to me that after calibrating sound levels for all speakers, the RTA would be invaluable in fine tuning - especially for sub interaction/cancellation issues. A fter reading the "Two subs makes my system sing..." thread, I realized that most people are just guessing about crossover frequencies, sub cancellations, and the like. Without an RTA, how does anyone know if there is frequency cancellation between their two subs in different locations? Granted, you could just make it sound good to you - but not everyone has heard a perfect HT. I'm sure it would be much easier to get great results in any room with any configuration if an RTA was used. Thoughts?
