In reply to:
Are there companies that will come out and calibrate your system FOR you?
I'm sure there are, but they'll cost you a whole heluvalot more than buying a Radio Shack
Analog, or
Digital, Sound Pressure Level (SPL) Meter, and a calibration disk like [url=http://www.amazon.com/exec/obidos/tg/detail/-/630551982X/103-8231176-2075006?v=glance]. It's not that complicated, and everybody here will be glad to help you learn how to do it. Knowing how will serve you well.
Thanks to Wid for posting the links. I'll add a couple more.

OOOOOOOOOOO! DEFINITELY Take Curtis up on that offer. But don't think he's just being a nice guy (which he is). He just wants to hear that EP600, and I don't blame him ONE BIT!
