Box help???

[fuzzai 10+ year member]

Hey guys, my brother has 3 JBL 10"s. there the GT100 Woofers, 4ohm coils...

Right now he's got a sealed box. with a 250w PG amp (at 4ohms) so it should be pushign near 4-500 at 2.3ohms id think....

I was thinking of building a Ported box, but never have before. looking at JBL's specs. they state a box of 1.75 cubs, plus the port should be at 25hz...

wondering what everyone else would recomend? for 3 subs and what type of port. sloted or port? and at what freq?

I hope you're getting one hell of a commission for all the advertising you do //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
