OK guys... here you go!
Please ignore the need for touch up paint... as well as the water spots on my camera. I threw in a little something extra at the end for fun. You can see I've prepared to get a projector and screen.
As for the IB's output, I took some SPL measurements with the most recent digital Rat Shack SPL meter. With Sonnies corrections for this version of the meter, the results are promising. For reference, I used Ethan Winer's test tones downloaded from his website. I'm going to have to describe the plot as I don't have a working scanner and the results were manually drawn on logarithmic graph paper.
Pink noise was set to 75 dB. The in room response from the main seated position started at 77dB at 10 Hz and steadily and for the most part evenly rose to 97 dB at 37 Hz (there were a few minor blips). It then dropped to 83 dB at 46 Hz. After that it rose to 100 dB at 56Hz (and stayed there until 63Hz). From there it droped to 95 dB at 76 Hz and then rose to 99 dB at 81 Hz (and stayed there until 100 Hz. Then it slowly dropped to about 75 dB at 140 Hz.
All of this was done with the amp gain turned up 100% and the level output from the integrated amp set to a point where the clip light on the Samson S700 has only flickered once. I normally listen to movies with the volume set at 40 (but the setup and levels are otherwise the same), but in order for the pink noise to be at 75 dB I had to have the volume set to 20. Although I don't have the manual in front of me, I beleive that when I set the volume to 40, the response is 20dB louder than it would be at 20! So, without EQ, I think I'm capable of 97 dB at 10 Hz. I'm sure I could turn it up even more, but I just don't like to listen that loud. BTW, the front left and right, center and surrounds all cross over to the sub at 80 Hz, and the sub also gets all of the LFE signal.
What I gather from this is with EQ, I can cut significant response across the board and still be flat to 10 Hz. Moreover, I'll have room for a decent house curve and not have to worry about destroying my Avalanches by overexcursion or clipping the amp. It'll take some work, but the potential is there!
And... just for a little fun, I thought I'd add this...
BTW, that is a bald man's head at the bottom of the last photo!
