sactownstang Posted March 23, 2008 Report Share Posted March 23, 2008 it's not only the box like they are saying it changes each way it fires..... I have a slot ported in a crx, if ports and sub are foward it's almost a db lower then if i aim at the roof. Aim towards the rear another .5 db gain. SPL= test, change, test, change, test, rebuild and start over testing.... Quote Link to comment Share on other sites More sharing options...

David Posted March 23, 2008 Report Share Posted March 23, 2008 from what I have read on the net, the jeeps like the sub and port facing the rear. to get res frequency you will need to do alot of testing, the res freq will change everytime you make a change get a 10" sub, build a 1 cube square box sealed, give this woofer 100wrms and start playing with it in the vehicle, move the box in various positions and run sweeps, write down the res freq everytime you run the sweep, it will change almost everytime you move the box in the vehicle PURE SPL is all about test test and retest then test agian Quote Link to comment Share on other sites More sharing options...
