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!

ptheo, thank you for sharing the magico s-sub info.  I wonder how much bass one needs in a typical HT or 2-ch setup? How big is your listening room? 

 I just installed a f212v2 last month in my HT room (15"Dx30"W).  Just one of the 212's is freaking amazing, I can only imagine two of 212's or a pair of Gotham's in my setup.  






lallitk- My room is 27'D-17'W. My complaint is not the output of my F212's(mostly 1/3 up & never past half way), but the way the drivers were working so hard once I cranked it up for movies(Mission Impossible- Rogue Nation beginning airplane screen) which causes distortion to rise which causes the MDF box resonate more which colors the sound/output. In my demo with the Gotham's, I got none of that. Just hard hitting clean/low distortion bass with no box resonating/muddying the sound. Sold!
Hmm...I am going to cue up the opening scene once I get home tonight and try to hear what you experienced. 

Also, the opening scene of Edge of Tomorrow has some serious bass, I think it gets down to 10HZ.  

Thanks!!
