Enclosure A. is the one I want to build, but i cant do that until i do aomething about the trunk lid tension bars.

Enclosure B. is just a back upin case A. falls through.

the only thing with box B, you may have taken it into consideration but i don't see the pic showing it, is that the port that runs along the back of the box will need to be 1/2 the width of the port exiting the box to to maintain proper port ratio. (like 2single lane roads merging into a doulbe lane road.)

second one looks better but if A is effective id have to see it in action

both look like they need more port area, and what subs only need that much volume?

the B box is vented through the rear deck @ the rear window. so in theory the reflection should make it sound good. like when you have the subs facing up at the rear glass of a hatch.

number two wont work. you need a divider in the middle. That port seperates the two sides, atleast how ive always been taught. You need a divider, and then design the two sides seperate.

what car is this in?

in most turnks, i think you'll find that it's the loudest firing towards the taillights.

also, recommended for type r's may be 1.3 ft^3, but all the designs i've seen that get loud are 2+ per sub after displacement.

i'd suggest a bigger box, more port area, and a slot port on the side of the box with subs and port facing the taillights.

can you spare an extra 8" of depth and do it right?

the speaker displement is .071 and xmax is 18.2mm

if they are 12 inch type r's they need DOUBLE that box. they need 2.5 cubes per sub, with quite a bit of port. Also, Second box will not work at all, i guess it will, but not how its planned to. You cant do the port AT ALL like that.

the site uses xmax to calculate the port area (enough so there's no port noise), i just changed it to 15.5 because i assumed a 4" wide port would be enough and it saves a couple inches of depth.

if space limits, use a single sub setup?

the T ports works for any sub enclosure as long as the port area is taken into account. if you are doing the T port desing using winISD, use dual slot port. make sure you look at the rear port- air velocity. it shoul be bellow 16.5 m/s to avoid port noice. then you can add the width of each port or the higth of the port, never double the length.
as far as having a divider in between the ports. is suggested to have a divides right in the middle of the port on the very back wall where the ports plit, with the same width opening of the ports rear ports, if its splits at 2" then a 2" or 2.5" divider is all you need. air will continue to run along to the opening of the port without problems.

so if you calculated a dual 2" port with what ever hight and a length of 16" then the port should have a 4" opening with what ever higth was calculated and then the same length but split 2" from the back wall and continues at 2" to meet the length of the port.

here is an image that may self explain it self.

looks good, just a small sugestion on the port divider it should be atleast 2" in depth since your rear ports are 2" that way your sure to help lower turbulance on that area. its not a big deal but it helps.

again looks good. now lets see some pics of the build up.lol
