I find it interesting that this list only includes ported designs.
Ported designs offer drastically inferior performance when it comes to group delay and time domain performance. They also are heavier, larger and more expensive. Their only advantage is that you can efficiently throw more low-end bass into the room with generally less THD on the lowest notes. For movies, ported designs are fine, but they are less than optimal for music.
For music, do ported designs sound terrible? Absolutely not, but they are not as accurate as sealed subs.
When you consider, though, that the way for a port to work, its contribution to the subs output has to be 360° out of phase with the output of the cone. Then you then have to run a steep high-pass filter just below the tuning frequency of the port. Depending on its design, that can cause the lowest bass from the sub to be another 360° or more out of phase. For a 31Hz, low B bass note, the fundamental frequency could sound like it started 70 feet (or more) to the rear of the initial transient caused by playing the note.
The good news is that all of this temporal mess comes in gradually as the signal goes lower and the human ear is, to a good extent, but not completely, immune to it.
For music, Rythmik's L22 servo sub costs $950, has two 12" drivers and two 300Wt amps. It will perform as well on movies and outperform all subs listed here on music.
