In my pre-BFD days, I moved my sub around the room and found the spot that sounded best to me was directly behind my listening position. When I got the BFD, I did not move the sub, I just EQed it where it was and was very impressed by the improvement. Later I started to wonder if moving the sub into the corner would give me more headroom, but it sounded good enough that I didn't bother to try it for a while.
I recently read an article that discussed the benefits of corner loading the sub especially with respect to phase and cancellations from the reflections off the walls and floor. The one disadvantage of corner loading is that you will excite all of the room resonances, but thats what the BFD is designed to correct, right?
Well, my wife was out all Sunday afternoon, so I took the opportunity to move the sub and re-EQ. Moral of the story? I gained 4dB!
Not only that, but the new location is in a corner close to my TV and mains. (My TV is in the corner and the sub won;t fit behind it.) I pointed the sub toward the TV so that at least the first reflection is coming from the direction of the mains. The percived directionality of the bass is now much more rooted to the front, instead of the more directionless bass that i had before. It's really great.
I just bought my first floorstanders and was listening to them full-range. I decided to put my pride down and objectively compare them set to "large" and then to "small" with an 80 Hz crossover. Well, you know what I'm going to say. I'm leaving them crossed over. The sub-bass makes so much difference.
BTW, your crossover muct be at least 80 Hz for watching movies with LFE. I recently learned that almost every receiver adds the "small" channels to the LFE before it low-pass filters the sum. If you set the crossover frequency below 80 hZ, you're going to truncate your LFE. (The LFE does extend up to 120 hZ, but it almost never contains much information above 80 hZ.)
