is my ported box a dud, pic

Wuzzup everyone i recently went to a shop so they can fabricate a ported box for my 2 tens took them 2 days i gave them the specs sheet and everything i know for a fact that this shop knows what theyre doing. well after i broke my sealed box i decided to try this and upgrade. well i pop in the subs and connect everything now i pop in my  E40 cd and the song i was listening to before dindt hit as low. before i would flex the roof of my car with a sealed box and now its nothing. dont get me wrong because i do feel that i got a lot more spl but not in the lower end.

since i went from sealed to ported do i need to retune my settings on my EQ and headunit or is this box a dud.

well i was listening to some more cds to test out this box and nope the deep bass i was loking for wasnt what i was expecting. the deep bass is there but it seems that is doesnt play as loud I know that something is wrong it seems that my sub strugles more with this box. there are some notes that it plays beautifully and loud and good i would say around 65-80hz. I was thinking it was the tunning on the port i dont know what it is tunned to.  the port size is    11, 1/2 tall  1, 1/2 wide and 9 inches deep.

do you guys think its a good idea to play with the port like making it longer to change the tunning freq.        Thank you all for your good help.

no i have the same gain that i had with my  sealed box the only thing i messed with was with the eq. I im having doubts that the problem might be in the ports
