well this is my first system and my first post so hello to everyone.
well i ordered 2 12's kickers l7's today got a deal on them and i was wondering what would be a good box to be built for these subs i want to go ported after reading about these subs being ported.

i figured i would go around 2.6net per sub so i need a box thats 5.2net after port and sub displacement

so i read up on how to make boxes and do the math this is what i came up with
internal measurements
24.5x29.5x15.5=6.5
minus .20 for sub displacement
leaves 6.3cuft

only other thing i need to do is figure out the port length and height for this box to be tuned at 33hz the port area if possible i would like to keep at 1.10 at the most

if possible could someone make me a sketch it would be most appreciated

thanks

well i would like to try myself for fun but i dont have all the proper tools so it prob wont end up right so in the end will have someone build it for me more than likely

yes i did and its kinda confusing lol i think my airspace is right and everything only thing i need to figure out is the port area how much and how to determine the size and the specs of it

That should be good enough, I think.

You should've gotten a sheet with all of that information on it when you bought htem. I'm not familiar with the L7's. So I don't know.

this is the one that i used when i needed to figure my port size. ive got a 15" l5 w/ about 4 cubes after sub and port displacement, mine is tuned around 33 hertz...m.ine is 3" wide, and 20" deep not sure if that is what you would need with ur box though.
