The 8, 10, and 13 W7 are all different than the 12. For instance going from a sealed box to a ported box the depth decreases, but not for the 12. Theres a few different things like that to. Seems like the 12 is the odd one out. Wonder why?
LOL, wow. I love your sig:
"Made possible by everyone at CA.com who helped me when I first started learning about car audio! Thank you for your patience and guidance!"
Then you hav the nerve to post something like that. Go away ****er.
Your question had no relavance to car audio! Who cares if JL has differences in the depth dimensions for their "recommended" box sizes for a certain subwoofer! Does it affect anything? No!
That's why I posted. If you're referring to my sig as an attempt to make me seem hypocritical, read what I just typed.
You're one to call someone out with that sig of yours...
