anybody know the volume requirement to rockford fosgate punch dvc subs (the old ones)

[NOAHS88accord]

I have some of the original fosgate punch dvc subs 12" and I want to make my own custom fiberglass enclosure but I dont know the requirements for these subs, and cant find them on the web does anybody know them?

goto rockford's web page and do a search there for it there. rockford 12" is prob going to be like 1.5-2.5 for seeled. ported is going to be a little larger.

[NOAHS88accord]

my subs are too old, they dont keep records on their site for them anymore

[87DXHatch]

Give me the model numbers and I will find out for you. also, if you have the T/S Specs, I can model it up for you too.

[NOAHS88accord]

I am in Korea for the army right now so i cant look at them to tell what the model number is all i know is they are the original rockford fosgate punch dvc 12 inch subs, I got them about 3 years ago but they just sat in my garage cause I never got around to building a box for them

[n88accordLX-i]

They work well in around 2.5cubes with good amounts of port I.E. 35+sqin

[NOAHS88accord]

will they work in sealed box? or do they need a ported box?

[NOAHS88accord]

is that 2.5 cubes per sub or for both? sorry i am not good at computing this shit, i usually have my buddy do the computing and i do the constructing its easier that way haha

[n88accordLX-i]

They do fine in sealed box's too, but if you want loud go ported, a big sealed box, around 2cubes with make those subs drop LOW. :super:

[NOAHS88accord]

hey man i appreciate it, can anybody help me out here and recommend lengths and heights and widths for me i suck at math and shit

[n88accordLX-i]

To figure Internal volume of a speaker box heres the formula.


Lenght X width X height = # /divided by 1728 converts it to cuft

Example lets say you want a 1.25 cuft box

12 x 12 x 15 = 2160 divided by 1728 = 1.25cuft

[87DXHatch]

Darn it anyhow, if he just gives me the sub's model numbers, I can give him enclosure specs that will be PERFECT for his sub... none of this "about 2 cubes and it will drop LOW" sort of BS...

[NOAHS88accord]

87dxhatch,

I would give them to you but I am currently in Korea for the army, I dont get home till march 14th, all i can tell you as of now is that they are the original rockford fosgate punch dvc subs 12" from way back haha

[n88accordLX-i]

i Think the model number is RFP1212

[87DXHatch]

Well, if it is the RFP 1212, then about 60 liters per sub will give you a really nice SQ set-up, sealed.

For more of a SPL set-up, go somewhere between 20-40 liters per sub.

[NOAHS88accord]

what you mean by liters? i need dimensions for the size of the box man help me out here lol
