If you are close to port Richy look up custom lowz on Facebook. Get one made way better then those and about the same cost. Built for your speaker, that's what's important.

The second one is better but a custom built would be much better than both. JL's are picky on box

YEAH u gotta check prefab box tuning i've only found 4 that were tuned close to claimed tuning.. sorry didn't get to finish typing grand daughter spilled water on keyboard............ ground shaker dual 15 and 12 boxes are some of the few i found to be tuned right.. and yes the 1 with 1 bigger port is better than 2 small and looks like it has some bracing as well..
