DUAL SUBS IN THE $10,000-$15,000 RANGE

I just sold my pair of JL F212's after hearing the Gotham(big mistake!). I'm about to drop $15G's for a pair of used(store demo's) Gotham's that have being upgraded from v1 to v2. Now since I'm about to spend big mula on bass, why not consider others awesome subs that may even be better than the Gotham's(if possible). I want my subs to do both music(primary) & bombastic movies(secondary) with LOW distortion. Please comments on the list below or add others I am missing. I listing them in my preference. Thank you!
