BOX DESIGN 1#

[matt402]

more port...

[Blackedout]

Box is too big. Not enough port area (Widen it, don't lengthen it. Length tunes lower, width determines cone control). Tuned a little low. Fs of that sub is 31. Tune slightly above it. 32-35. ~15 sq inches of port per cubic foot of box.

http://www.directeddealers.com/manuals/OG/Orion/GHCCA102%202008-11MLweb2.pdf Page 18 gives you a bunch of info. Looks like they mixed up sealed and ported enclosure, but 3.6- 5 cubes is typical for a 15. They recommend tuning at 38.

so the box should be even smaller?

woopsy, the sub discplacement shuld be .15, cuz its 15" sub right? i was thinking it for an 18"

size of sub (diameter) doesnt determine displacement

to an extent, it does. put the same size motor on a 10" cone, and it'll have less displacement than that same motor on an 18" cone. the cone itself is bigger, and most likely longer overall so they'll still displace different volumes.

however, 3 hundredths of a cubic foot will not make a difference in the output in this instance
