Just picked up a set of Energy Take 5.2, which sound great in my tiny HT room. The receiver I'm using is an Onkyo TX-SR600 that I'm using for the first time after buying it a few months ago. Like any educated HT newbie that reads these forums, I bought an SPL meter and even helped a few friends calibrate their systems. When I run my Avia disc and select the option to configure the speakers, the Onkyo emits its own built-in test tone, instead of using the Avia one. They each have a different pitch, so it's easy to pinpoint which is which. I can't find a way to adjust the speaker levels without using the receiver test tones, which I've learned is not as reliable as the Avia one. Is there something I'm missing, or should I just settle for calibrating my system with the receiver's own tones?
