vladd 26 Posted May 5, 2009 IIRC subs up and ports back is the basic CRX style. That doesn't mean it's the best (always best to experiment and the only real way to find out). 0 Share this post Link to post Share on other sites

dbjunior 0 Posted May 5, 2009 from what i know best in the lanes setups tend to be sub forward port back in a sonotube style box not sure how it does daily though. 0 Share this post Link to post Share on other sites

1200 bandit 2 Posted May 6, 2009 Subwoofers up ports to the back. Try to use areoport an the numbers for the crx box are 29x29x15 with 4 4" port. That box works good with two 15s, two 12s, an 4 10s. That is just one box that work good ( 140s ez with the power) Good luck hope I help you. God loves Bass an us. 0 Share this post Link to post Share on other sites

God loves Bass an us.I would think that 2 15's would need a considerably different box than 2 12's. plus if you are giving out box dimensions, you should probably include port length and/or tuning 0 Share this post Link to post Share on other sites
vladd 26 Posted May 7, 2009 considering it's an spl box all normal guidelines go out the window. optimal box volume doesn't mean jack to most spl freaks. 0 Share this post Link to post Share on other sites

RustyWCA 0 Posted May 7, 2009 keep the ports rear firing, the subs firing up, to the side or forward are all within tenths of each other. genrally forward is the loudest, 0 Share this post Link to post Share on other sites

Rapatari 0 Posted May 7, 2009 from what i know best in the lanes setups tend to be sub forward port back in a sonotube style box not sure how it does daily though.I know a couple CRX'ers around my area and they all went from the traditional CRX box to the sonotube style and all of them got louder. 0 Share this post Link to post Share on other sites
Aaron Clinton 2,372 Posted May 9, 2009 Search out "The Scraper", that is Terry. He is pretty much the best at CRX boxes in street classes. 0 Share this post Link to post Share on other sites

Godsmack 360 Posted June 1, 2009 You can easily fir a 15" in a CRX.............the sonotubes are USUALLY louder, but the tradition is subs up, port back as already stated.J 0 Share this post Link to post Share on other sites
