hi i got a dd 2512 d2 sub (I cant find its t/s parameters)

at ddaudio.com there is a 2.5cuft design for 12" drivers DDAudio.com | Digital Designs : Speakers Made in the USA

What do you think about it, should i go for it? Whats that box tuned to? Re calculator says 35hz but i think its a little bit off.. Its a side port/sub back design, and i have no idea whats better in a trunk car.. sub&port back or sub fired back/side port? what kind of bracing i need in that kind of box? thanks!

A manufacture recommended box by a reputable company... I'd trust them. DD boxes are usually tuned 38-40.
