2x f113v2 vs 1x Gotham

[phishphan]

After moving my gear into my new house and listening room I realized my little ole f112 just can't keep up. Even my wife said we need more bass in the room, so that's the nod to spend more stereo money. I'm very loyal to JL so I'm not thinking of any other sub brands. I've had their subs in my cars, homes, boats.. and never been disappointed.

I went looking at JL's website and realized how much more the Gotham is than anything else in their catalog. Does anyone know what the difference is between running 2 f113's vs the Gotham? I could buy, at MSRP, 2 f113 subs for 9k. But the Gotham is 15k. That just seems a bit nuts considering there's 3000 watts powering a single F113 and "only" 4500 on the Gotham. I would think there would be far more SPL generated from the 2 f113's.

Thoughts?

I've also thought about picking up a couple of 212's as well and moving the current one to my living room upstairs.
