okay, need some quick help on a box design for a friend. Hopefully want to build this on wednesday. This will go in the rear of a 92 celica hatchback.

max dimensions:
32"wide
15"deep
19" tall

i want this box to be ported at like 32hz.(square/rectangular port) Also, if it was sep. chambered...how many cubes would that be? and common chambered how many cubes? thanks for the calculations!!! hit me up on aim next time u see me...then hopefully sum1 can explain the calculations to me so i can do it myself in the future...but these are in a hurry. thanx very much...peace

We would also need what kind of speaker it is... that would be a REALLY big help. We would also need the Theil/Small Parameters for that sub or at least a link with those parameters. As for the design software do a search on yahoo for WinISD PRO and download it i think the website is http://www.linearteam.dk/ go there and download it;)

Assuming your using 3/4, the volume of the box as a whole would be 4.17cu'. If you seperate the box, you get 2.05cu' for each side.

As far as vents go, according to WinISD, ...

Seperate chambers: 6" tall x 2" wide, and 12.36" long
Shared chamber:12" tall x 2" wide, and 11" long.

I'm not sure if this is how wide and tall you want the port, but it will work.

thanx, i appreciate the help. I'll prolly go with separate chambers...it's for 2 10k's, so 2 cubes ported for tens should be enough...and with that port(sep chmbered) what is the tuning on that. Thanx, peace

...just what you asked for...32Hz. With a peak of 2.3db at 35Hz. Should sound pretty nice.
