To those that have used REW, is it worth the time, effort and investment to get the $95 mic and spend time learning the software? Or is using the receivers built in calibration tools (MCACC, Audyssey, etc) + SPL meter + some manual fine tuning a better route. I've been reading about it for the past day and it seems easy and complicated at the same time and I'm wondering if it's worth the effort and hours spent configuring everything.

Will you hear the difference between either way?

Basically, this is what REW allows you to do, only accurately.
You can get as serious with REW as you like. If you "just" want to get a flat frequency response curve, okay, aim for that. If you get interested and want to pursue decay rates and the like, you can, but you don't "have" to.
It's just another aspect of the hobby. I have a meter and I calibrate my video. I have a mic and I calibrate my audio. Most of the time, it's fun. It's always interesting. And the result is that I'm getting the best performance possible out of the equipment that I have, modest though it may be.
For the $100, you may as well try it and see if it strikes your fancy. I'm sure you can sell the mic if you decide that it's really not for you.

For those wondering, Soundflower is still required on a Mac if one wants to send output to particular channels in a surround setup. Finally got it all working and it's SO MUCH easier than removing patch cords etc!

Thanks, I'll give it a shot. Noticed that Cross Spectrum is out of the UMIK-1's right now though.

Using REW and using AVR calibration tools are entirely different things. Every listening room has audio characteristics that affect audio quality. The placement of your speakers, and the amount of room treatments can correct for audio issues. REW is a tool to assess the audio quality and assist you in determining whether adjustments in speaker placement and treatments are resulting in improvements.

Any thing you do to get your listening room in the best audio shape before you run automated room correction, the better the correction results will be. But REW room-tuning does not REPLACE room correction. If you have automated room correction, you should still use it, because it is the "icing on the cake" that corrects other audio issues that cannot be fixed with speaker placement and treatments.

So, long answer, but the proper approach is to use both, because they compliment each other.

Edit: I should add that using both REW and automated calibration together always results in a better solution. Unless you have an exceptionally good listening room, automated calibration by itself rarely corrects all the audio issues.

It has been discussed many times in this thread--there are advantages to ordering the mic from Cross Spectrum Labs because you receive customized calibration files with your purchase. The price difference is not significant. Either the UMM-6 or the UMIK-1 microphones are functionally equivalent.

Right. And he can't get the UMIK and the UMM can be returned within 45 days.
Also, the calibration files from Dayton have been shown to be perfectly adequate for the beginning hobbyist.
So he can get his hands on one now, give it a try, and see if he wants to keep it or get a calibrated UMIK eventually.
I, personally, am not especially good at waiting.

He could also send the mic from Dayton (or anywhere else) to Herb at CSL for calibration if availability is an issue.

I find it fascinating. I was drawn to REW because I didn't like the sound of my room and my new subwoofer purchase. REW let me see exactly what was happening in my room and helped me fix (or greatly address) the issues.

Everyone's hearing is unique. My wife doesn't hear a difference and couldn't care less. I am much happier. Just be aware that depending on your personality, you can very easily get hooked on using REW and fiddling with your stereo more than using it. If I'd never gone down this rabbit hole I probably wouldn't be contemplating purchasing 3 more subwoofers!

That would no longer be cost-effective (see, I'm not only impatient, but cheap, too. ).

Dayton's calibration is fine these days, yes, for a single mic position.

Cross Spectrum measures at multiple angles, which is a time saver if you want to measure many different speakers without moving the mic each time.

--

Heck I was surprised how close the mic was to linear WITHOUT the Cross Spectrum file. Certainly close enough that any obvious problems were still obvious!

Is the goal here to match the flat black line it give you?

I have been playing with it for several hours now and this is much better looking than it was before

Its just one sub. i tried doing multiples at once and it was a total mess.
