well i am ordering a pair of quad coil 12" Axis's tomorrow and will be porting these in my wagon.... i used to run my old 15 sub up port back, should i do the same for 2 12's, or do i do sub back port back?

also these only need like 2 cubes or less right? tune to 30hz im thinking

anyone wanna do a design for me by any chance i would be grateful once the subs arrive i will build the box and start bumpin.

Max dimensions?

Id stick with subs up port back. AP recommends 1.2 - 2.1 cuft ported.

max dimensions is:

37" wide
21" deep
height isnt a problem especially with the enclosure these need shouldn't be too big

sub and port back, port cenetered between the woofers.. anywhere from 1.5-2 is ideal.. 30 is plenty low.. most music never goes under 40hz most, maybe 1 out of 10000 songs drop below 35hz..f3 should be around 26-28 with that aligment.... sub up port back does good for burping.. spreaing the woofers the width of the cabin helps pressurize the cabin as a whloe instead of tring to pressurize the dash...

Alright, here's one for both of them...It isnt perfect because it isnt tuned as low as you wanted :(

But it comes to:

-2.12 cubes per sub, net
-39.375 sq inches of port area per sub
-Tuned to a hair under 33Hz

at like 44lbs i should double baffle for sure right?

Pioneer~Saturn

I usually like a double-baffle with my subs or you could put some bracing on the back of the baffle and it'll do pretty much the same thing

Gavriley2007

that enclosure should work out very nicely

Gavriley2007
12-26-2008, 07:54 PM
a couple people in the past day have told me to just run aero ports, and have no port noise, and it would sound better and probably be a hair louder

spy told me you box designers actually run a probgram to see what size works best and what not?

i just wanna know if i should just run 4" aero per sub and cut to my length for tuning

thanks members,
matt
