nuboot Posted April 24, 2010 Report Share Posted April 24, 2010 so when it comes to tuning a box using multiple aeros how do you determine the tuning freq. for example i have a box with 6 in pvc used as aeros how do i determine how long to make each to get a desired tuning of lets say 30-35hz o yeah my box is 8.25 cubes before displacment Quote HEADUNIT:Pioneer AVic d3 WIRING: 8 runs of 1/0 knu gnd and pwr BATTERIES: 1 shuriken bt80 upfront 4 in the back COMPONETS:powerbass 3xl in front dooors powerbass xl in back doors 6.5s AMPS: 2 powerbass xa3000d powerbass Asa 400.4 SUBS: 4 db drive plw 15s ENCLOSURE:12.7 cubes 32hz ALT: 150a stock for now VEHICLE:05 chevy trailblazer sitting on 24s iTRADER FEED BACK http://www.caraudioclassifieds.org/forum/itrader.php?u=1289 Link to comment Share on other sites More sharing options...

bassl0va Posted April 24, 2010 Report Share Posted April 24, 2010 They combine. Imagine getting all those ports and squishing them into one. The area adds up, but the length stays the same. So work out the area, then divide by 6, then work out the diameter of each one, and cut all 6 to the length you worked out. BTW. Aero ports are flared, meaning the ones in the pic aren't aero ports. Also, aero ports change tuning a bit.

nuboot Posted April 24, 2010 Author Report Share Posted April 24, 2010 (edited) i know that i even said that they were pvc but should work somewhat the same. now i just got confused heres why for the size of my box and for tuning to be 32hz the length would have to be roughly 32 inches now is that for each individual or for all 4 combined Edited April 24, 2010 by nuboot Quote HEADUNIT:Pioneer AVic d3 WIRING: 8 runs of 1/0 knu gnd and pwr BATTERIES: 1 shuriken bt80 upfront 4 in the back COMPONETS:powerbass 3xl in front dooors powerbass xl in back doors 6.5s AMPS: 2 powerbass xa3000d powerbass Asa 400.4 SUBS: 4 db drive plw 15s ENCLOSURE:12.7 cubes 32hz ALT: 150a stock for now VEHICLE:05 chevy trailblazer sitting on 24s iTRADER FEED BACK http://www.caraudioclassifieds.org/forum/itrader.php?u=1289 Link to comment Share on other sites More sharing options...
bassl0va Posted April 24, 2010 Report Share Posted April 24, 2010 If that 32"s was worked out for the combined port area, then each one is 32".

bassl0va Posted April 24, 2010 Report Share Posted April 24, 2010 Yep, and it doesn't matter if you have 100 1" ports, they still have to be 32". I guess you might have to go back to the drawing board?
