it's a long time since i done any of this but i need to make a sub enclosure.
the sub is a JBL GT4-12 and the amp is a JBL 2000
rest of the system is
kenwood kr-v8090 - av amp
jbl control 1's - speakers
jbl gto 508c - crossovers
jbl gto18t - tweeters
at the moment i have this POS FLI 12" sub box with built in amp
and its farting, sounds horrible at higher volumes and makes everything in the livingroom
rattle and vibrate even at quite low volumes and thats not the kind of bass i want.
I want nice tight punchy bass not the low sloppy rattling kind i have now.
having a bit of an argument with a mate about sub enclosures, he's adament i should use a ported design
tuned to about 30hz where as i want to use a sealed enclosure.
I have pdf of the sub which goes into thiele small parameters if anyones interested in seeing it.
so anyone done any of this stuff before and what would be your reccomenation ?
