Thanks for the info, I am wondering if it would be worth the money to have a professional come in and do it.

The reason I say this is because I have been trying to do a little research on the net and have been reading about things such as calibration DVD's as well as the SPL meter. I figured that if I was going to outlay a couple of hundred on this stuff then why not just pay to have it done properly.

I would assume it would cost me around $200 - $300 for a professional.
