Subwoofer Size/Box Help

I just had a question on JL audio subwoofer products. I am limited in space and want to know which would sound the best and hit the best on the power and box specs given. All the box specs will be JL Audio spec boxs. I will post it and it will be powers by 1200-1500 RMS.

2 10" JL Audio W7 in a 3 cubes net volume tuned to 34hertz. Powered by RF T1500BDCP or a nice 1500rms amp.

2 12" JL Auido W6 in a 2.6 cubes net volume tuned to 33 hertz. Powered by JL HD 1200/1

1 13.5" JL Audio W7 in 2.5 to 3 cubes net volume tuned to 34 hertz. Powered by JL HD 1200/1
