I didn't ask that. What are the OFFSETS you put in to reach 75db?
Also how long is the cable you are using?
What type of cable are you using?
None of the 3 above questions are relevent to MRC. I use a cheap 30' Belden RG-6 coax cable with cheap RCA F-Conn terminations.
The more significant question would be is it 75ohm.
Pure and simple...MRC has problems. M needs to step up and address all the issues. It should work the 1st, 2nd, and each subsequent time without a problem -- no matter who's running it and their level of experience.
Which would you rather have?
Let's say you have a bad woofer in one speaker?
Would you want MRC to succeed and do the best it can or fail forcing you to dig deeper and find the problem woofer?
The checks are thorough and usually points at a problem.
I have used systems that a bad woofer would pass, Meridian's would not.
Reporting offsets does help eliminate possible problems. If they were very lopsided (between left and rights) it could indicate a bad woofer that was compensated for by calibration that won't pass MRC. His offsets look great. Actually almost too good to be true.
I'm not saying MRC is perfect and I would love to see a V2 of it. But this phase (Measurement) is fairly easy to get through. Unless something is broken or out of whack.
Let's see what he comes back with after skipping some speakers.
