I'd tune a little lower with a little bit more volume for a more SQ
I think, but i'm still new to this

true! :crazy:

but im not looking to win any comps with them so this set up would lean more to the SQ side i guess but i know they will still put out very good lows

i have a DDLE12 in my GF tacoma on only 200w from a jensen LSA600 :eek:& it does pretty good nowhere near what it can though

i used DD website for port area and box volume but jack at DD said to run a 22" port my ? is: is that 22" per sub or 22" for the whole box

Your port length is off. If you're wanting 4ft^4 after displacement with a 35hz tune and that size of ports, then they need to be 31" long.

Right now that box is tuned to 40hz.

What vehicle do you have? And how much power do you have to give these DD512's.

This box should get the job done for you. Its 4.25cuft tuned to ~35hz w/ ~14sq per-cuft port area...it will be fine w/ those DD512's.

External measurements are 31.5 x 15 x 24. Port is 4.5w x 13.5t and actual length is 24". Make sure you put a brace between the subs, a 3.5-4" brace will do. Wedges in the back corners will help also.

but ill cut out the area for the ports or would areos be better for this setup

so should i just do (2) ports 2.25w and 12" long
