Back on topic..

If you are going to use that bandpass box, it wont matter too much which of those subs you buy, bandpass boxes conceal alot of distortion, you likely wouldnt be able to tell the difference between them. Just get whatever matches well with your amp's power output.

EDIT: and for the love of god DONT just cut down those ports to make the subs fit. The length of the ports is EXTREMELY important for the sound of the box, you cant just go cutting them, it will make it sound worse that it does origionally (I hate prefab bandpass boxes, they are extremely peaky and boomy)
