    You could, but be aware that the non-linear frequency response, and the change in frequency response cardioids have as you go off-axis will make decisions based on what it hears quite difficult. An Omni with as flat a response as you can get would be better.

    No, I wouldn't recommend that Microphone for testing purposes of your room. Those large diaphragm microphones exhibit really poor off axis response. Yuck. And for that reason, they're not used for room measurement purposes. Only very small diaphragm condenser microphones are used to test room responses with. And that's because the small diaphragm condenser microphones have really great off axis response unlike the large diaphragm condenser microphones. And that's very important when measuring the response of your room. As well as they should be also Omni-directional, not directional cardioid's.

    So you've got the wrong stuff for what you are asking to do. In fact, you might actually be better off with a cheap, Taiwanese, tie tack/lapel microphone. Because those are very close to the actual scientific calibration, expensive test microphones. Closer than you realize. And all for $20 US or so, each. And then, they only require a 1.5 V, AA battery and no phantom. The battery can last for hundreds and hundreds of hours. But before it needs to be changed. I recommend changing the battery before any testing or measurements. We do the same thing with wireless microphones, just before the show. We don't use old batteries. Neither should you.

    There ya go.

    An addendum here on the cheap, tie tack microphone. The cheap $20 tie tack microphone works well because its response is actually relatively flat. And it really doesn't matter how awful that microphone might sound to you? You're not recording anything with it unless you want to. It's only used to measure room response. Though it can still be used on other instruments. Not necessarily recommended as a primary microphone but merely as a highlight microphone. Say for a quiet Oboe solo in a symphony, on a truly low-cost budget job. You tape it to the music stand. It'll work well that way. I've used them for that. Certainly not quality oriented but usable. With that $20 version. I've used the $300 + versions you see on the newscasters on TV. Those are excellent. Sennheiser's & Sony's, Countryman and others. It was necessary for television when the director didn't want to see a single microphone. And even with those compromises, I still got an Emmy nomination. You can too. Compromise is not a dirty word. It's something one has to do, frequently when mega-budgets are not involved. Just so ya know.
