So I just tried it w/ a better powered mic. It did not reverse the phase on the sub, but it still turned it down to -11 .  I changed the settings on the crossover, and the sub, but left the rest the same.  I'm going to give it some time to see if I like it. I also want to use my Dayton Mic to RTA it w/ my settings vs the auto eq settings. I'll post up the results. 

I had ordered the Pioneer mic though amazon, but I'm going to send it back, I forgot I had an ATR-3350 laying around.

If you're going to run an RTA application, best to use a calibrated mic and load the calibration file into the RTA application to compensate for mic response deficiencies.

The mic you linked only has a freeq of 50-18k.  You have to remember those range values are the 3dB down points at the end of a freeq plot, from mean response value (0dB), and they continue to roll off outside that range.  On top of that, the dB swing could be all over the place in between the range values.

The mic I used for RTA comes w/a  calibration file for the iPhone.  I loaded it up to my phone. It's a different mic than I used for the Auto EQ.  

Also is this not better than the Pioneer mic?

Can't say for certain.  I'd guess yes... but a guess is all it would be.  Would need more info and listening tests to draw a definitive conclusion.

So, has anyone determined a good microphone to use with the NEX's?

I'm also curious what to use.

I used the mic that came with my SC-07, which appears to be the same as the accessory mic offered.

And while I was a big fan of what MCACC did for my system connected to the SC-07, the NEX Auto-Cal failed miserably. It got the time alignment wrong, sub phase wrong (which is not surprising given the time measurement issues), and the levels, crossover points, and slopes were far from ideal.

So... IMHO, nomatter what mic you use, if you use autocal as your starting point you are doomed to failure.

Recently tried out the mic intended for my Denon Audyssey calibration with my NEX-8100.  I put it facing forward hanging slightly off the top of the drivers seat.  It did much better than the Pioneer mic.  Mids are no longer tuned out like before when using a flat EQ setting.  It resembles a lot closer to my previously manually adjusted tune, but seems to have tuned the frequencies I was struggling with in between some bands from before.
