Well i just got 2 Alpine Type X 12's. And i have them in a ****** ported prefab right now & powering them with a MMATS 3100.1 Im goin to build a new box for them but i have no idea how many cu.ft. they like and what to tune the box to. They are going to be in a Suburban and i just want SQ not boomy ****** bass. I want the bass to be nice and tight. Anyone have any experience with Type X's ??

yes put them in about 1-1.25cubes each sealed.

Not ported?

You said you wanted SQ.

Well yes but i would like to get the most out the setup. These are power hungry subs. Im thinking 2cuft per sub tuned to 35hz. Any opinions?

4th order bandpass.

4th order bandpass.

Never built one before. I want to keep it some what simple as a slot ported box.

ok well scratch just SQ... I want SQL. Is aprox 2cuft(each sub) @ 35hz what i need?

3cF sealed.

Alpine states 1-1.25 cuft sealed. / 1.5-2.0 ported .......3cu.ft. might be a bit much

No, Alpine's Steve Brown states in last months issue of CA&E that 1.5cF each sealed is what they recc, even if you'd email or call that's what they'd say.

3cF sealed.

Oh for both of them... My bad man i thought you meant each... Im like :wow:

jesus christ I keep getting these stupid FORBIDDEN screens!

I'd still say ported.

Low tuned. 32-35 hz. 2.5-3 cubes a piece. :)

Go with sealed for the type X. 1.5 cubes per would be perfect. :cool:

If not 4th order then I'll recommend sealed. As far as SQ goes.

01-27-2008, 09:14 PM
I went with 1.8cuft each tuned to 35hz. Sounds pretty fcukin good!

I have my type r tuned to 32hz in a 2.3ft^3 box with a 5 inch round port and it gets off really well running on an mrd-m1005 at 2ohms which is a little more power than that speaker likes but if you watch it, its good.
