Ok this my first time tring to design a box. So i'm looking for some advise on this design.
The box is 14H x 39w x 18 D
3.39 cu ft atfer speaker & port displacement (1.70 cu ft per speaker)
50 sq of port area (14.75 sq per cu)
tuned to 35 hz (4" w x 25" L
Question start here!!!
1)Did I do the port right?
Its 4" wide x 14.5" L and then branches off to 2" w x 10.5" L (both ways)
2)Are the kerfs the right size?
I started with a sloted port. Then measured back 2"(half the port opening) to start the bend. I did the same thing to the inside port. will this keep my port size =.
3) Do I need to 45 the other two corners? I did the corners close to the port. Also are they done right? I also measured back 2" from the inside corners to get the size of the 45's
4)Are the bracing i got good enouch? Did I go over borad on the bracing and how do i get the dispacement on it? I don't want to below 1.5 cu ft per driver. also will the bracing effect my tuning alot? The braceing is 3/4 mdf with the spaces cut out. I'm tring to keep the port from flexxing as well as the walls. The brace in the port will 1/2 in dia going thru 3/4 mdf. All will be rolled over.
