I guess they both accomplish the same goal, I just prefer the single button method, that I just figured out 2 days ago. :) I found that when using the volume (sub level) control in my MiniDSP, the display in the software doesn't always update correctly, so I have to type in the correct levels, then muting as needed to avoid doing that again. Just recent experience still fresh on my mind.

Haha, I’ve just been called out by an “internet expert” on the other forum who said what I did in the first post isn’t possible...
sometimes I just have to laugh otherwise people would drive me mad...

I just ordered a nice shiny new isemcon emx-7150 :)
How did you make this decision? There are a lot of products on the market.

So might fall back on the focusrite. The motu measures (not that it is audible) better than the focusrite and I like the look better.
Why do you need an M4? A Motu M2 will do the trick.
Re: Sub level and how it effects phase alignment and crossovers
From my understanding of Smaart, if I ever expand to two (or three) microphones, I would need 3 inputs (two microphone and one loopback) and the m2 only has 2 inputs so would only be able to be used with one microphone and then the loopback.
The price difference isn't much either so that was my other reason.
For car purposes I would probably only ever need 1, but my wife also teaches high school theatre and has her own youth theatre company where the more microphones would be fun to play with in the bigger space.

OK. Gotcha. You have a good point. BTW, I love my little Motu. It sounds good and has a nifty LED level meter in front :)

the smaart users group had a post about measurement mics and the isemcon was declared by lots of people as king of sub 300 dollar mics, I wanted a small capsule (1/4” tip) mic which gives better off axis results, it can have more distortion at higher volumes but that’s a trade I am happy to make

Edit* just played around with this, it gave me the same time alignment of ~2.20s for EVERY driver except sub at 0...This would not give me a center image....
Looking at the image, it says "measurements do not have a timing reference". Would you not need a loopback with a timing reference to make sure you have absolute relative phase between the two drivers measurements? Then, the time shift method might work with good results?
Re: Sub level and how it effects phase alignment and crossovers
I had an acoustic timing reference setup in the preferences and the measurement window. I am not sure why it was still saying that. I may have just choose measurements for this picture that didn't have that set up. It has been too long now and I use Open Sound Meter (free) or Smaart ($600) now for phase. MUCH MUCH easier!
