I am looking to get a mic so I can do some speaker design work, and am just about to pull the trigger but noticed someone mentioned a UMik1 doesn't have ability to extract phase the same way a mic like the Dayton EMM6 can, and that you need to do a workaround. Is this correct?
If so, is it more beneficial to have a calibrated UMik1 or an uncalibrated EMM6? Or both?

Buy a normal mic not an USB mic.
Then you don't have those problems.
What you should buy depends on budget.
Cheap Dayton EMM6 or Berhinger MC8000.
More expensive Earthworks.

Well $200 Canadian is my limit. The Cross Spectrum UMik1 is about that with shipping etc. Or just a standard EMM6 I can get for $70 Canadian. I realize calibrated is better but if I cannot do proper phase measurements then it seems like I'm better off with the uncalibrated Dayton eh? I wish they still calibrated those.
The only microphones with published phase response are from B&K. The issue with the USB mike is that you doi not have two live channels to compare phase. Most software working with one mike derives the phase response from the frequency response. Its an OK compromise but won't resolve some phase shift/time issues. An analog mike into a two channel sound card with the other channel monitoring the audio into the speaker does allow for real delay/phase extraction. Conventionally the microphone is assumed to be free of phase shift. Actually at the diaphragm resonance (HF) it will be at 90 degrees and the rolloff will commence almost immediately. In most measurements you can ignore this.
