//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif I don't understand what you're getting all bent out of shape for; I just made a truck box for 3 of those guys in .35 cubes net ported, and they honked like I've never seen. Customer said **** it, give them .5 a piece and they sang. IIRC, JL's specs are .3 or .35, but in real life experience, that's on the small side.

i would think and im no pro at car audio but i would guess that a company would do a good bit of R&D before they set a spec for something

The enclosure Gross Volume is .44 cu.ft. ( subtract sub and port displacement ) an it will be slightly over .35 cu.ft. Net Volume.
As stated previously, it's possible and I mean possible to put a 2" dia port to the spec's also previously stated, but it would be a royal b!tch to put them in there and to be honest, I'm not overly thrilled that the OP is limiting his option to this port.

i do not want to limit myself to a particular port design i was just going by what JL speced the ports to be if another style port would work better and still get me to the 35Hz tune recommended by JL i would be open to it

Technically speaking, the enclosure wouldn't require any bracing .... period.

The xmax of these subs given the power they can handle for the enclosure they need, bracing in any form would be a shear waste of volume. I know this, but some people have this notion in their heads that bracing in one form or another is needed.

I didn't perpetuate the bracing requirement, but idiots long ago that saw certain subwoofer companies that built enclosures with bracing and thus it must be that enclosure's as a standard require bracing in some manner.

It's a d@mned if ya do or d@mn if ya don't mentally, people with show their enclosure designs with or without bracing and posers are giving their opinions from all sides.

Well, guess what ---- SCREW'EM. Nobody here or aboard is any great authority on the issue, myself included and therefore the adage - Opinions are like azzholes, everybody has one.

The OP of the thread is the one making the decisions, his concerns and what not are all that matters.

To say what's right or wrong is purely nothing more than points to be argued and debated till he!! freezes over and quite frankly a waste of time, it's like beating a dead horse, been there, done that..... good grief ---- are we there yet!!//content.invisioncic.com/y282845/emoticons/noevil.gif.0723d47b61c306c6d554fb6555014096.gif

my thing is if the enclosure needs bracing in areas by all means brace it if it doesnot need bracing to still be a good solid box and hold up to usage that i see no use in it the way i see it if it doesnt need it dont do more work that needed

bad03ranger,

Your calling the shots and what you want is what you will get.

I'll have that other thing we discussed done tomorrow ( eh, it is tomorrow already ) later today.

ok i do like others input b/c i do not know much about this but like i said before if JL recomends something than more than likely its b/c it works best in that application if we can work out this port issue and i like the design we may have a go at it im assuming this is how you pay ur bills and not a side hobby so its kinda what will work best and be the best quality also will you be carpeting the box for the price u gave in ur PM if i get one from you

 

[Mr Cabinetry 10+ year member]

I need to know if and what is obstructing the top of the enclosure ( RED ) and at what depth the obstruction comes out over across the top??

 

[morgans432 10+ year member]

Phil is a great builder and knows his stuff man. You still have to hear my subs in that box man you would like it.

 

[bad03ranger 10+ year member]

this is the area that limits me from going above 11" but it sticks out 1.25"

this is the maximum TD at 3" above the offset of the rear cab wall

wow thats not a great pic the measurement is 2.5" at 14" from the bottom

not sure if i said this before but this is for a 2003 ford ranger

Son, I'm not contesting you or JL audio, and with that said, Mr. Cabinetry is one of the best on this site, but the fact of the matter is, I'm stating real world experience. RE doesn't say to give their SE 15 8 cubes tuned to 18hz, but it can make plaster fall off the ceiling while watching Cloverfield in the home theatre. No one is telling you what to do, just relaying experience that might help you in the end.

Phil - that is .35 net per sub, right?

Yeah, .35 cu.ft. net.

bad03ranger changed up the design alittle, but, his and my way of thinking about it sort of crossed over into we both were thinking the same thing and in the process allowed for the enclosure to gain more volume so I can do slot ports to give him alittle more port area than the 2" dia port area.

I'm working of the final revisions of the enclosure as we speak.
