Blackedout Posted June 17, 2011 Report Share Posted June 17, 2011 (edited) 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.

Torres Posted June 18, 2011 Report Share Posted June 18, 2011 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 Quote Link to comment Share on other sites More sharing options...
