ported clamshell help/build

[AMI CUSTOMS]

All of those would be fine, it is just your choice, did you factor in bracing too? I would be leaning toward the 36 x 6 out of all of those.

[irpirate]

used 1.25 cubes for bracing. 36x6 was what i was leaning towards as well. i need some ideas/help with the port though. i wont be able to get 15-17 inches of port length without splitting it into two sides. so i stays 6 inches from the back. should i put something in the middle to get an angle on the ports? ill do a quick sketch of what i mean.

[irpirate]

struggling a bit. what im trying to figure out is what to do with the port when the split from both sides connect to each other.

[irpirate]

added some port. changed the calculation to three common walls.

the beginning of the port goes for five inches. the split goes around 6.5 for each side. 6 inches away from the wall for both. im not sure how splitting the port changes the tuning. any ideas?

*edit - with this box ill only get around 1 cube per sub maybe ill switch the amp from a 3500 to a 4500 and juice them a bit more if this is what i do and i dont feel like its performing like it should. also, the widest part of the clam/opening is 14 inches tall.

another thing ive been worrying about is fitting all the subs in. width is 12 3/8 x 3 = 37 1/8. so im most likely not gonna be able to do nice neat rows, but ill defintely make it fit!

*edit - fuck me...this is gonna be tough getting them in...

Hey man i'm tring to do the Sketchup for you. But the problem i'm having is that 3 across wont fit. I know they are 12's but the overall dia. is 12.5 on the those sub. And if I do 2 across and 3 deep it doesn't leave much room at the back of the box. How room is need from the back wall. This model leave 7" to the back wall.

its gonna hafta be 3 deep. no other way of doing it :/ just pack em in as close to the front as possible lol. everythings gonna hafta be right up to the edge. like thissssss. btw its 8 subs on each face

i really appreciate you taking your time to do the sketchups. thanks!

man... more and more uncertainties are making me nervous as hell

[irpirate]

with the subs setup like that im thinking im gonna have to use threaded rods for bracing. not enough room to fit wood and itll save me some displacement. sorry if i seem to be posting a bit too much. ive been sitting here working only working on this for like 40 hours week or so. gotten to the point of just sorta posting whats on my mind.

This is why I generally design first then buy the woofers, saves you headaches.....

if you cut holes that close together all the way across the damn thing its gonna have practically no support and be hard to brace.
