Now i've done a search and looked at all the links i can find, but i've fallen short.

Here's the situation:
I'm hunting for the specifications for the kicker comp vr sub (12", 2 voice coil, 2 OHM). I need to find what the best enclosure for these subs, I have an orix??? box purchased through jb's. I want to build my own install (again) and i'm searching for info on the best litreage / cubic feet required for the subs, i have two of the subs off a kx600.1 amp.

Now i'm predomidatly into rock/metal but listen to all music, so i really need a good all round setup but leaning towards the clearer punchy bass, not the overall boominess. Now i wanna know the best style of box (ported or sealed) for the music but i don't want to restrict the subs.

Now i could just recreate the origional box i have and face the subs to the back (i have a false floor made up and it fits the subs facing forward, but not facing the rear) hence having the subs on the vertical surface not the slope.

Any help is greatly appreciated

Try the kicker site... all speaker specs with thiele/small parameters should all be there....

IIRC, these like about a 40L sealed/65L ported at 45hz.... but i'm probably way out.

so how big should i make the box?

Using the T/S specs supplied and guessing your cabins internal resonance I am getting 1.09cf sealed. :)

t/s specs???

Theille small - as above.

They are just all the specs about ur subs.

Marty has spoken. Sealed box for sure.

i have 2 x KickerComp VR's....

mate, i had them in a sealed box...No good.

we went with an extended port double box !


this box put out the best accoustics, and deepest / loudest booms ive heard in a while !

where can i get the specs for that box??

Kicker specs for all their subs are very broad, but effective nonetheless. For your sub in particular, Kicker recommends anywhere between 1.0 to 4.6 cu.ft. sealed or 1.75 to 2.25 cu.ft vented.

I agree with Ice_Magik too. Sealed boxes do not do these subs justice.

:D
