Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

There's a reason Alpine doesn't give recommended vented enclosure specs for that sub.... It's made to be used in a sealed box. I used one in a 1.5 ft^3 sealed box and was pleased with the results.

im currently running 2 SWE-1042 10"s in a vented enclosure and they hit pretty good, but i can get a good deal on 2 SWE-1242 12" so i was just wondering

also anyone heard anything about or used alpines PLV-7 or PLT-5 ?

i personally agree with boardinbum. although you can make a vented box for just about everyspeaker. you would definately need to be careful with alpines. and if you must go vented, please use a subsonic filter!! they are great if you would (i know it sounds old school) make the box slightly larger than asked for or put some good ol' polyfil in the box for deeper bass. but alpines tend to clip easily especially in a vented box once you crank 'em. they are a great speaker on lower powered amps (esp type e) but will buckle under pressure.
