Box designer get in here! Please

[CleanSierra]

Beware, I ran the exact same subs on triple the RMS and the soft parts failed me. The surrounds tore themselves apart. Coil was still nice and pretty, but the surrounds on both did fail. I think the isobaric would be a badass idea man. Maybe even an iso 4th order?

I only got a audio pipe 1500.1 so won't be killing them. Now just need a design

Meade did a 6th Iso with 2-12" AA that was bad ass

[CleanSierra]

Yeah, he didn't go through with the thing because it was a pain in the ass to get right, if I remember correctly.

John, how much port do you think would be good for 2 in an isobaric 4th? You think 80" would be enough or too much?

I had some numbers crunched but it was for 4. Maybe just half the port area?

[john253a]

Idd aim for 1.5net 25sq" of port

Yes for all 4

On a cone to cone

But you'll want at have a gap of the height of sub +3/4" so you'll probley be 2.5" or so between them

Idd probley do a cone a mag through

With about a 7" gap

But ill check the number when I get a moment

[CleanSierra]

25" of port for a regular ported box, or a 4th order John? 25" sounds good for a vented enclosure, but doesn't sound like nearly enough for a 4th. I would think 40" would be in the ballpark.

[john253a]

Standard/regular ported

Yep you would want more on a 4th

But you don't want to risk unloading either

Even no you have 2 sub in such a small enclosure

I'm no expert when it comes to 4th+

There not hard to build but to get what you want takes time and most just want something to bump and done yesterday

So I've had very little time to play around with them,

Because of the 2 verables (4th and iso) I would be tempted to eliminate 1 to risk the chance of building several boxes to get the right one

We no 1-1.5@15-25sq" of port works well with 1 of thoes subs

So being an iso box 4 should do the same in the same enclosure

[john253a]

On another note

Op could always go sealed

[Joe X]

Well, 4 cheap 12 subs to be placed in a not too big trunk sounds like bad start to me, OP keep it simple, sell the 4 little subs and get a couple of really better 12s and do a nice box for them, it will be louder than the iso setup, much simpler to build right and will sound nice as well, say a couple of Fi X or SSA GCONs on that power.

while I am a fan of SSA, I (and hopefully you too sag) would like to see some designs of what the hell these guys are talking about and how all this reasoning works. Please bestow your wisdom upon us!
