This was disclosed to me by John Mulcahy of AV Nirvana. Those two changes solved my issue.
John is the guy who wrote REW, so I'm pretty sure that he knows it better than anyone! And glad he helped you figure it out.
I am going to attach one file to see if my speaker is still not producing enough low end.
They still aren't going down very low. I would have expected better from those K12s, but I guess they don't really have the low extension. You could try flipping the LF switch to "deep" (which is how I have the ones set that I use for live sound), and see how that goes. The problem then is that it won't give flat response, but to be honest it's more useful to get good bass out of them, rather than accuracy, for a live room.
I noticed that the knob on back was set higher than 0dB, so I set it to 0db. not sure if that or the PYLE was the reason for the lack of low end.
That's just a gain control on the back of the K12: it cuts or boosts all frequencies equally. Did you re-calibrate REW after you adjusted that? They ideal is to get a level of 86 dBC at the mic position, or at least 80 dBC. The REW manual says 70, but that's not so realistic for studios, where you want to be sure of triggering all possible modes at typical levels.
My guitarist and keyboardist will not be using amps but going directly through the PA speakers when we rehearse. So for them I figured I would set my speaker where the PA speaker would normally be (raised in the corner) and then do some mic tests at a couple locations. Does that sound good?
Sure! For some of the tests, do set up the K12 where you intend to have your PA speakers, and in that case set up the mic where you expect the keyboardist and the guitarist to be when they are playing. But also set the speaker up in various other locations, where you expect to have instruments while tracking.
I just finished my tests. All 39 of them!
Wow!... OK, I'm downloading those, and I'll take a look tomorrow.... That's a lot of data!
Since I can only have 30 on one file,
Actually you can increase that on the preferences page. Go to the "view" tab, and look for the setting called "Maximum measurements". I have mine set to 99 measurements (as I often need to analyze dozens of measurements in one file), but to get it that high you also need to choose a higher memory allocation when you install REW. It's probably worth setting it to something higher than the basic 30.
