wonderboy Posted April 12, 2012 Report Share Posted April 12, 2012 I'm in the process of designing a box for a MA HK15X2 to fit in my 01 Eclipse, In order to get 5 cu ft, fit in my trunk, and keep my back seats, its gonna have to be shaped goofy as hell. I'm not even going to attempt fiberglass so thats not an option. I'm using CAD to design the box so I know I can get an accurate volume measurement, but how will the shape of the box affect the tuning? The sub will be firing up at the rear glass and the port will be horizontal and facing forward. I'll post some screen shots of my design so far after i snag them off the computer at school tomorrow.

skittlesRgood Posted April 12, 2012 Report Share Posted April 12, 2012 it wont change tuning. the contours may affect output but its not enough that i think you should worry about it.

ALPINE408 Posted April 12, 2012 Report Share Posted April 12, 2012 air space is air space.... you have to worry about air flow but mainly for spl if its a daily box your good Quote Have you ever had your woofers blown? Link to comment Share on other sites More sharing options...
wonderboy Posted April 13, 2012 Author Report Share Posted April 13, 2012 Thanks, that's what I was half expecting. Is there anything I need to compensate for when using a port length calculator?

TeamHT Posted April 13, 2012 Report Share Posted April 13, 2012 Air is air, but sometimes you would be better off with a smaller box than a bunch of weird pockets trying to get 5^3s. Pic of said trunk? And why would you want 5^3s for that sub? If it is just one, I would put it in like 3^3s tuned to 38hz Quote Tell me...does this smell like chloroform to you?

Pic of said trunk? And why would you want 5^3s for that sub? If it is just one, I would put it in like 3^3s tuned to 38hz Honestly, thats exactly what I was thinking. The recomended ported box size is 5 cubes though, and I didnt want to screw anything up. Here are some pics of what I have so far, and the trunk. It doesnt look all that small but the depth from the back to the little bump behind the seats is only like 24 inches, and its only 15 inches high under the hatch so having the sub fire backwards is impossible. From the top of the back seats, its about 16 inches to the back hatch at 20 inches high. The most narrow part of the box is about 22 inches and the widest part at the back is 46. Any suggestions would really be appreciated. Haha I dont want to put a ton of time and effort into this box and then have it sound like shit.

wonderboy Posted April 14, 2012 Author Report Share Posted April 14, 2012 And just in case it wasn't obvious, the part of the box that is raised and narrow up would fit over that bump behind the seats and then the sub would fire up into the glass.
