What I was hearing was not buzzing or rattling. The sub was around 4' behind me and 2' to the left of me. I don't really feeling like getting into an argument, especially with you. If you have never been able to localize a sub with an 80hz crossover, that's great. I think that is too high if the subs are going to be placed anywhere other than along the front stage. With the subs on the front stage, I couldn't tell where they were.
