with 2 113's you can find optimal placement flexibility within your room much better which is always going to have low frequency suckouts and nodes. Much superior than just one imo. With bass, you have to live with and work with the room. The flexibility of 2 that you can place just so is a huge plus. Don't forget you have to lift these suckers and move them around until you find their "home" in your room.
Two Jl Audio f113's or one f 212
I'm curius as I am looking to buy a sub that i will not have to replace for years. i know they both would be awesome but as power and punch which would be the best. I'm still not sure if I need 2 f113's yet. I kinda thought if I really didn't need 2 I could sell 1 for close to what I paid. But if I get the f212 it will probably be the last sub I would need for a while. Any thoughts or opinions is greatly appreciated.
