So I'm having some issues with my mic that came with the 3009. It reads a whole 5-6dB higher than the one that came with my 608. Also, before I go on explaining my issue, know that with my Onkyo 608 I always had my subs volume knob turned to 9 o clock and it set my trims to -2 or -3dB.
So my issue is that I was using the 3009 mic to run Audessy XT32 and it asks to match your sub's dB to 75. With the 3009 mic (with my sub setting at 9 o clock) it said 86dB. So I literally had to turn both of my subs almost all the way down to "min" on the back to get down to 75dB. After the whole setup, it set my subs trims to -3.5dB. I then proceed to put on some of my favorite "bass" testing songs and it was very lackluster, didn't feel a thing and barely heard it.
Next I rerun audessy with my subs set at 9 o clock and ignore the "75dB matching" thing. After the setup it set my trims to -11 and -12dB, again my bass was very lackluster.
Finally I put in my 608 mic and compare the dB readings during the Audessy setup. With my sub set at the 9 o clock position, the 3009 mic reads 86dB, while the 806 mic reads at 80dB. Seriously? Just a bad mic?
Also, I am curious if I can just use the 608 mic to run the whole Audessy XT32? Is it the same exact mic? Worse? Better?
