My VSX Pioneer comes with what is touted as one of the best and easiest speaker calibration setups. (that's what "they" say). Anyway, it come with a microphone and a dedicated port it plugs into and I move it around to the main listening positions and it sends out test tones, etc. and tweeks the speakers. I dont' know if this is measuring SPL (doubt it) or just using some sort of DSP matrix to match what is "heard" to a given table and setting the speakers accordingly. I have two questions.
1. Is this as good as having a modest SPL meter (like the radio shack) in setting up the cross-overs and such?
2. Would it pay to use an SPL anyway and manually adjust the levels?
Thanks. And as always, great information from everyone here. Wish I could contribute as much as I ask.
