So I assume you're going to be running the 1200.1 @ 4 ohms?

I'd go with the first one...

Doog you've got a nice setup dude.



Go with the first box, alpine recommends a 0.7-1.0 ft^3 box.. the second one will have a little bit too much space.

heh, we dont have any rebels around anymore that like to go outside the 'recommended size' anymore :)

and btw, when you are going with sealed, having it 'too big' couldnt hurt it that bad at all.......

Well, it could ... It does reduce power handling. But it sounds a lot better when you use a 1.3-1.8 ft^2/sub sealed box with the Type-Rs ...

By the by, companys usually recommend boxes that peak (****ing peaks) in the 40-60 Hz range. I'd much rather take a nice, flat response curve that has more low-end and a better transient response than peaky recommended crap ...

yea that peak response BS is why companies build bandpasses.....bleh.

Hey WeDoog, I'm interested in getting a ported box for my 2 12" RE SE's. Resonant Engineering recommends 2 Cubic feet each sub tuned to 35 hertz. Would you think about making me a box?

i had 2 type rs briged at 1 ohm in sealed box that i threw together in shop class one day, all the demensions were correct and **** but im gettin another type r. could u make a box for 3 with about .8 or.9ft^3? if so.... how much u charge? im lookin at this

right now.... its a little too much air space so i figured id screw some of my left over mdf flush along the inside of the back wall and seal it up to reduce the air space but.. if u think u could hook me up with about box thats better than that.. i might take u up on it

fyi.... the back of my explorer is 42 inches so that would be max length... ill take it sealed or ported, which evers cheaper :D .... i have carpet for it so u wouldnt have to worry about that either

how much would you ask for that box 91lacdeville??

Also did you say you were going to run 2 12" alpine Type-R's on a JBL1200.1 at 2 ohms??? you do realize that is giving like 650 watts rms to each sub and the Type-r's have an rms of 300
