BIG Bass in a Small Room - Making Infinite Baffle Subwoofers

After the very encouraging results I got from the open baffle subs experiment, I decided I'd go all in and put them directly in the wall. This is known as infinite baffle, where you are just getting output from the front of the drivers without any interaction with the back wave of the speakers. My listening room's front wall has a utility room behind it, so it's nearly perfect for this setup. All I had to do was cut out the drywall directly behind the woofers to open them into the space. The utility room acts like an infinitely large box and completely eliminates cancellation from the back wave of the woofers. I did have limitations on where in the wall I could put them, and this close to the floor isn't ideal. But the results are outstanding - flat bass extension down below 20Hz in the room and the woofers are neatly out of the way. These are four 12" woofers with each pair wired in parallel (for a 4 ohm load) and driven by a 100 watts per channel Yamaha receiver that can deliver nearly 200 watts per channel into 4 ohms. The "Mad Max" recording at the end was done on a Zoom H1 using the built-in mics from the listening position. The Zoom H1 has two mics built in for a "stereo" recording. Not the greatest mics or recorder, but close enough to give you an idea of how the room sounds.
