matt14 Posted April 28, 2011 Report Posted April 28, 2011 So i need some help with a box. Ive never built a box before. I have a DC XL 18 off a Crescendo 3k at .7ohm. Sub will be up and port back. So what i have to work with is 49"w.16"h. 20"d. I still need to be able to use some of the cargo area for strollers and diaper bags ( 2 year old and a newborn at home). This obviously will be in my daily driver. I used torres box calculator to start with, but really need help with the port. How do you determine how much port length to use and which type? Do you use aero's, slot,etc.... I will use a double baffle and likely 1" dowels for bracing. Any input would help. Would like to get this done in the next week or two ( meca coming up and would like to see what it does ) Just some info, i listen to all types of music except country, but mostly Rap.

CJ18 Posted April 28, 2011 Report Posted April 28, 2011 You are gonna use the height, width and length boxes for the port. You want to build a slot and not aero so stay away from the other 2 boxes. Quote
mazdaspl Posted April 28, 2011 Report Posted April 28, 2011 What would be your tuning choice? I think those XL's like it around 35hz.. jay Quote
matt14 Posted April 28, 2011 Author Report Posted April 28, 2011 Thats what i was thinking was around 35-37hz.

matt402 Posted April 28, 2011 Report Posted April 28, 2011 Thats what i was thinking was around 35-37hz. from ur info i did a port thats 14.5"h x 6"w & 19.25"d (tuned to 35hz). Quote
matt14 Posted April 28, 2011 Author Report Posted April 28, 2011 So the depth of the port should be almost the same as the depth of the box?

CJ18 Posted April 28, 2011 Report Posted April 28, 2011 The port is going to have to turn along the back wall of the box. Quote
matt402 Posted April 28, 2011 Report Posted April 28, 2011 The port is going to have to turn along the back wall of the box. x2. the port would need to bend & be 6" away from the back wall of the box, since its a 6" wide port. Quote
