Stephen Raab Posted March 7, 2014 Report Share Posted March 7, 2014 OK so I am trying to design a box for a DC lvl4 15" I would to try and keep the net volume between 2.75 and 3.25 cubic feet. I would like to be tuned to around 33-34Hz. This is going in a 2005 Mazda 6 4Dr sedan. It is going to be a sealed off trunk build. My maximum useable space is 20" tall 40" wide and depth is something like 36" but I don't see it being any where near that deep. As for the sub, the mounting hole is 14" the outside diameter of the driver is 15.7" the mounting depth of the sub is 8". I would b like to have as wide of a port as possible. I hate it when guys have this nice box with a big 15 or 18 and then try to run a 2" wide port.(lol) Any help with this is appreciated and thank you in advance. If you need any other specs or measurements just let me know. Link to comment Share on other sites More sharing options...
ChevyBoy95 Posted March 7, 2014 Report Share Posted March 7, 2014 well, if your port is 18.5in tall, then your port only needs to be 3-4 inches or so wide. Otherwise you end up with a box that peaks like a mofo and isnt musical generally.

Stephen Raab Posted March 7, 2014 Author Report Share Posted March 7, 2014 Chevy I was messing around with Torres last night and I'm thinking I want to go 18" tall which puts the port at 16.5" could I get away with a bigger port that way? Say maybe 5 or 6" wide? Link to comment Share on other sites More sharing options...
ChevyBoy95 Posted March 7, 2014 Report Share Posted March 7, 2014 Maybe, not 6in wide, but maybe 5.

Joe X Posted March 7, 2014 Report Share Posted March 7, 2014 Throwing in a second option, whatever you end up doing you need to make sure your box will fit in it's way inside, subsonic filter to 28Hz: Link to comment Share on other sites More sharing options...
Stephen Raab Posted March 7, 2014 Author Report Share Posted March 7, 2014 ChevyBoy95 and Joe X thank you guys for the designs. Curious, would one of these boxes perform better or are there any advantages to one over the other? Also, maybe I am stating the obvious, but would there be any benefits to filling the gaps created by the 45's with foam? Link to comment Share on other sites More sharing options...

Jose luis 12 Posted March 9, 2014 Report Share Posted March 9, 2014 Those are some good looking boxes. What program is that? I need a box for my new sundown x12. Link to comment Share on other sites More sharing options...

Also, maybe I am stating the obvious, but would there be any benefits to filling the gaps created by the 45's with foam? as far as the 45s with foam, no need to. and to which one is better, it will be a role of the dice, i would personally go with Joe's due to the lesser amount of port turns, but i have had a great deal of success with the port that i did. So either or, both will work.
