I second the JL Audio brand recommendation but I think (hear) that bass is stereo, too just like the rest of the spectrum. I use a pair of JL F110's and love the sound. Had one larger sub before these and two are definitely better than one for my system. When I got them I unpackaged them, put them in place, used the auto room optimization, slightly repositioned them once, and was done. Just like that. In my experience with two you can run at a lower level which makes them easier to integrate and avoid common sub issues.
