Different Calibration Files

[jagman]

I downloaded my unique calibration file from the MiniDSP website for my UMIK-1. Actually I downloaded 2, 1 in June 2018 and one today (2 years later). A pic with both are attached. Is it weird that they have different Sensitivity Factors? Please see the attached pic...

BTW the sensitivity factor is the same whether its the 90' calibration file or not so that's not it.

And now I just got an error when clicking the SPL meter tab... tonight is not my lucky night!

Interesting... I just ran sweeps of my L C and R and then my Sub. First I ran Audyssey XT32 to get a calibration file (ignoring the sub). Audyssey said to lower the sub level 12dB, which I removed. Then I setup REW and ran the sweeps (first 1.2, then 1.1. then 1.3, then 1.8). I overlayed them and snipped an image. This definitely shows potential.

As for my setup, I have screen at the front with two rows of seats. For speakers I have DIYSG HTM-12's for LC&R and for my subs, I have four FiCar Audio IB3 18's up front, eight Anarchy drivers under the row 1 couch and four Infinity Reference 1262 subs directly behind the row 2 Theater style seats. This is in an open loft so there is no room gain and no pressurization (hence the nearfield subs). Given that the open space is literally about 20,000 cubic feet I'm pretty happy with that response. To add to that, I have not done any integration with the subs (no delay or phase work yet). I literally just plugged them into the MiniDSP Balanced 2x4 and ran the sweeps.

Now I need to work on aligning the phase and delay and then add in a few PEQ bands and I should be in great shape. Time to read up more on the newer developments in REW.
