After all this I re-did the sub crawl, and decided to leave it where it is. It's 10 - 12 db higher than other areas of the room there and is mostly not in the way. I re-ran Audyssey, bumped it a couple db, and I really think that is all I can do with it.
You're not looking for the location where the sub sounds the loudest. You're listening for smooth, even bass. If it sounds loud, it may be that there's one frequency piling up which will make all the others suffer.
I think it is the Digital Video Essentials DVD which has some low bass sweeps, which also show the current Hz on the screen. Anything with a bass sweep would work though. While you're doing the crawl listen to the full sweep in each location, it should sound (or even better, measure) equally loud through out. If using the DVD, you can even get an idea what frequencies are being accentuated or lacking. Sort of a poor-man's REW.
