It's always good to hear both sides of the argument. The crowd around here is made up of audio nerds who love to do everything by hand and tweak to their hearts content. So you're going to hear a litle of "do it manually". Now there's nothing wrong with using an RS SPL meter and the Avia disk, but that's not to say the mic is horrible.
I own the mic, and have used it more then one ocassion when I add some new to the room, or felt like re-tweaking. It sounds very nice to my ears. One of the big reasons for me is I can't read the analog SPL meter (I'm visually impaired) and so this was a lot easier for me.
In fact I'm not even fully sure *how* to calibrate with an SPL meter... do you just sit in one spot and make note of the meter readings as Avia goes through it's test tones? or what?
Anyways the mic quite nice, sadly I can't remember where I put mine
