Ok, calibrated EMM-6 microphone... check. Art usb dual preamp... check. XLR male to female cable... check. Looks like it's finally time to take some measurements.
So yeah, I took the seating out of the home theatre room, moved the subwoofer to where the seating was, placed the calibrated mic on a tripod at various locations throughout the room, and then took readings with REW to determine the best bass response (from 80hz down). Where it's at its best, is the best spot for the sub to go.
First off, the right wall (where there's the big window) was total shit. Here's how that one looked halfway along that wall:
As you can see, that one goes to hell in the early 50's, and it ain't that crash hot to begin with. I then proceeded to try the front of that wall, with results that were pretty much just as bad:
Yeah, that's another epic dip around the mid 50's. I figured anywhere near the window was crap (as I've read others have generally experienced).
At this point I took a reading of the original spot, which was behind the seating position to the left:
That actually ain't that bad a spot. It does dip in the late 30's early 40's, but not by too much.
This next reading is along the middle of the left wall (just past the door):
I knew this would be bad, because I'd done the traditional subwoofer crawl playing the Ironhide flip from Transformers 1, and that had sounded terrible.
Next I moved on to the front of the left wall:
Much improved, although still something of a nasty dip in the early 50's (I figure still a bit too near the door). So here's a shot of the mic up to the left side of the front wall:
This is the money shot, if you ask me. The best spot in the house. It dips only a few dB's in the early 40's, aside from that it's just great.
Unfortunately, with the SubMersive on the table, it's height actually ends up a little above where the screen goes (wouldn't you know it), so I've had to put it closer to the front left corner, which looks a bit more like:
It dips a little in the early 40's and 50's, but once again, only by a few dB's. Nothing near the -15 to -20dB drop I was witnessing earlier.
I'll let you know how it goes after I've had a chance to recalibrate and then check out some bass-heavy content :)
