me and my friend made a ported box tuned to 28 hz ... we followed the volume according to the specifications of the subwoofers (2 12" pioneer premier ts-w3002d4) ... we made 2 separate 1.4 cu ft boxes ... the output is not what we thought it would be ... we want it to be louder and maintain sound quality ... what size cu ft box should we make to get more output? .... should we combine them into a single box? ... if so how do you do the portwork insde?

I think 1.4 cu. ft. is a little too small for any 12 inch ported woofer. My 12 suggested 1.85 cu ft. but i went with 2.2 cu ft. tuned to around 31 hz and it got plenty loud for me and it sounded just awesome.

I would recommend 1.75 - 2.5 (per woofer) net volume including speaker, bracing and port displacement. I would tune around the 33-38hz range. You could do a single chamber box and create a L-shaped slot port.

alright thanks ... i am sorry i do not know if i am misinterpretting what you are saying ... do you mean 1.75-2.5 cu ft with the sub in or with the sub out ... i know i get all confused when displacement is used in a sentence lol

With the sub, bracing, port, etc. in.

So after you have all that in the box you should have 1.75-2.5 cu. ft.

so if my sub was say .25 cu ft the box should be 2-2.75 cu ft?
