ported or sealed?

go on alpine's website and download the owner's manual if you don't already have a copy.

Sealed, with a max depth of about 8 inchs with an angled back if that helps. i tried looking on the alpine site and the owners manual on the alpine site and i couldnt find much info at all regarding the recommended enclosure size for them. if you could get a link for me that would be great?

Thanks

If you go ported.

2 - 2.5 cubic Ft after displacement. 32-35hz tuning.

I only tried ported with my pair in multiple boxes. I like LOUD.

Thats the new style, he is asking about the old style. OP, to be honest, I wouldnt even bother sealing up a Type R. I hated mine sealed, it didnt sound any better and wasnt loud at all. I then put it in 2.3 cubes at 34hz and it sounded decent and got hella loud for an 80 dollar sub

is there any chance someone who is willing to help me design the box full on could shoot me an email to give me a hand thanks. i will most likelyy be getting it built professionally, but i would like to take some plans into them to show them what i want.

The only way to do a wedge enclosure with 8" maximum depth is to build the box extremely wide or tall. For example:

height - 14"

width - 30"

depth 1 - 8"

depth 2 - 6"

That'd be 1.13 cubes before displacement and I'm not even sure the sub would fit.

i was thinking of making the box fairly wide. my max top depth is 6inch and my max bottom depth is 11inch? does that make things easier?

i have scribbled some figures together and this is what i came up with, however i think these number would only work for a sealed box.

Height: 14inch

Width: 37inch

Top Depth: 6inch

Bottom Depth: 9.5inch

And if my calcumalations are correct that gives 2.32cubic feet in volume???

Is this Correct?

Thanks
