Brendo, the corner resonance wasn't related to low content. I'd say it was somewhere between 50 and 70Hz. I haven't heard it since I moved one sub out of the corner.

The 125 is real nice for most ladies. Females are anatomically more sensitive to low bass to the point where they ask for it to be turned off. The nice thing about the 125 is that it doesn't go down low enough to be a pain for them. It's also physically smaller of course which they tend to like.
