Where do people come up with this idea?

The only reason I can tell where my sub is in my room is because it feels like the vibrations in my floor are coming from that direction. It is crossed over at 60hz though which helps.

Try the room crawl method; playing the sub at the listeners postion and then crawl around the room on your hands and knees until you find the loudest most even bass response. Thats "X" and that marks the spot where you put your sub. My sub is located behind the listener's position (in this case, a 4 chair recliner) and bass cannot be localized to it. This technique works all the time.

As it was explained to me by a fairly knowledgeable guy, the high end roll off of a sub doesn't drop off like a cliff, even if you use the receiver's cross-over; it is a gradual roll off. This means that no matter where you cross over your subs at, you will still get output from them above 80 hertz, although, of course, it won't be nearly as loud. Still, it will be audible enough to give the sub's position away. Multiple subs can stop the localization (as long as they aren't co-located, obviously), especially when they are placed near the front stage speakers.

^^That's correct, hence the term "crossover slope". Even a 24db low-pass slope starting at 80hz is only 24db down at 160hz, and I think you're more likely to see a 12db or 18db slope generally.
