"OMFG, Krypto is getting a mic finally!"

Scott Simonian from AVS sent me his mic and ordered me some cables from Parts Express. I have REW downloaded and installed as well as the mic correction files, but I am a novice and complete nooB at mic/REW/measurement so we are just getting started at setting me up. I ran an SPL test at 14Hz and 18Hz so far, it may be a day or two before I get a good FR responce curve measurement. Here are the vids and pics copy/pasted from AVS to show the initial SPL tests just getting to know the mic.
The mic and cables from Scott:

at :59 that crash you hear is my girlfriends Christmas Globe falling from a shelf and shattering. My nuts are now in a vise. THANK YOU SO MUCH SCOTT SIMONIAN FOR THE MIC AND CABLES! I hope I pronounced your name right!!! The noise you hear while bursting is things rattling/squeeling throughout the house, never bottomed out drivers are clean and clear.

This is from the 33-2050 cal.
so at 14hz youre down about 23db.
You'll want to aim the mic straight up. You can provide sound output to your receiver via hdmi, however the cables are to hook up your mic to your PC's sound card input.
10.0 -37.20

so I connect the mic RCA out to the Y splitter, to the 25' RCAs, to the other Y splitter with the jack, to Line In on PC?

117dB uncorrected at 18Hz, 135dB!

They're fuzzy, but should give enough info on things such as a perspective on the entry way, how far the bedroom door usually is open, the plaster that is coming off the lathe (admittedly on it's own, not from 135dB of 14Hz) the structure of the bed platform, space between and above towers.
My girlfriend and her son finished moving in the rest of their things, some things strewn about. Not quite the same bachelor pad it was, for the better I hope.

Interesting first 3 posts, a dozen fuzzy pictures, a very fuzzy cat, some satellites, a port opening, a link to a video and are those rabbit ears on top of the cabinet in the last photo? That's some loud speakers you've got there, you don't often see those kinds of numbers outside of a mobile installation. Not really my thing, but impressive nonetheless.

5dB increments to see compression starting at -40dB ending at -10dB master volume. Yup, thats a 130dB peak Yup, thats solider than solid a 10Hz, yup, look at that 6Hz
15Hz on up

DC on up

subwoofer SPL meter readings. for a DIY sub. Super low bass. Most commercial subs only go to ~20Hz range (on average). That or other's that go that low by the time they hit the super low (<10hz) theres a major loss of SPL.

Are you trying to shake your house into a pile of rubble?

As a former sound engineer, I know what it all means, I'm just not sure why you would do that.
It seems like such a mess, and money better spent on a better house/apartment.
Reminds me of the ghetto setups on CAF or SD.

Why would one spend tons of money on a car? I dont get that. Everyone has their hobbies. Mine happens to be skiing and football (real football). if you knew they why even say "what is this i dont even"?

id say thumbs up with regards to money for results (since i have followed your threads on avs i know bit more too). As for actual readings, bit to much for my personal liking. im actually loving my sub set to ~90db at 20hz be fun to play with your set up but i wouldnt use it much at all.
