FiNaLaLmAsY Posted February 23, 2012 Report Posted February 23, 2012 okay torres box calc for 33hz tuned box with aero ports says box: height 15.5 width 36 depth 21 2- 6in aeros by 28in long for 33hz do you divide that number in half and make each one 14 in long or each one need to be 28in long? i know seems like a dumb question but i can not find a correct answer and is torres pretty dead on by time i add my .48 cu displacement for woofers? 02 Nissan Sentra 4 DD 3500g 10's Crescendo Audio 3500 @ .5ohms Soundstream EGA4220 Fronts German Mestreo 6.5 Component Set 110Rms Rears RE XXX 6.5 Component Set 2ohms 220RMS 1 Dyralast Gold 1000Amp Battery 1 Vmax 2000amp Battery DC Power Inc 270XP Amp Alternator BIG 3 Upgraded All 1/0AWG Setup 8 1/0 Awg Runs
412 CVX Posted February 23, 2012 Report Posted February 23, 2012 each one needs to be 28 inches long, imagine (i know it's not correct) that 2 6 inch ports = one 8 inch port the port would need to be 28 inches long to get 33 hz, Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.
FiNaLaLmAsY Posted February 23, 2012 Author Report Posted February 23, 2012 well then that answers pretty much my question now let me ask u why torres says i need 28in and psp port calc and other sites tell me lik 23in =33hz and on the other sites i took the woofer displacement volume i had to use since it doesnt count for that.. 02 Nissan Sentra 4 DD 3500g 10's Crescendo Audio 3500 @ .5ohms Soundstream EGA4220 Fronts German Mestreo 6.5 Component Set 110Rms Rears RE XXX 6.5 Component Set 2ohms 220RMS 1 Dyralast Gold 1000Amp Battery 1 Vmax 2000amp Battery DC Power Inc 270XP Amp Alternator BIG 3 Upgraded All 1/0AWG Setup 8 1/0 Awg Runs

412 CVX Posted February 23, 2012 Report Posted February 23, 2012 because the volume of the box is about 1 cubic foot more in the precision port calc. just go off torres. i've used it on many designs and they've worked out pretty well each calc is gonna tell you something slightly different. you won't hear much difference between them as long as they're all somewhat close Just say no to Ground Pounder Customs.
