Tim Lam Posted June 19, 2012 Report Share Posted June 19, 2012 hey all, so i currently have a ~3 cubic foot box for my 2 12" Type R's. with that box i have a make shift 4" aeroport tuned to ~35Hz. playing full tilt i sometimes here port noise. should i add a second or even third aeroport? and if i do add X amount of aeroports, will this make my system louder?

Noobtastic14 Posted June 19, 2012 Report Share Posted June 19, 2012 Adding ports will do a number of things. Without adjusting length, you will be completely changing the tuning frequency and response of the setup. If you do add an aero and adjust the length of each to keep approx. the same tuning, you will see a slightly more output at your peak freq. and a steeper roll off below it. -Drew Quote I am a United States Military Arts and Crafts Professional.

Smoove Posted June 19, 2012 Report Share Posted June 19, 2012 you could put bends in the ports or have them exteded out of the box. Or 1 6" flare port 15" long with a bend Quote 2 Team Fi 15's v1 2 DD M5's 970amps of Alt 6th order blowthroughThe truck Blowthrough build : http://www.stevemeadedesigns.com/board/topic/155555-smooves-1996-chevy-ext-cab-c1500-slow-build/The 350z build : http://www.stevemeadedesigns.com/board/topic/170694-smooves-2003-nissan-350z/ My FB page https://www.facebook.com/pages/Smooves-Car-Audio-and-performance/719746144805343 Team Fi Audio http://www.ficaraudio.com/ Link to comment Share on other sites More sharing options...
diatribe Posted June 19, 2012 Report Share Posted June 19, 2012 Here are some bended aeroports a used on my AA Avalanche 15". I think it was tuned around 27Hz. Quote Link to comment Share on other sites More sharing options...
Tim Lam Posted June 19, 2012 Author Report Share Posted June 19, 2012 ahh! i see, very interesting. i didn't even think an aeroport could be designed with bends like that. that would much more helpful. thank you very much for the pics, didnt understand the concept without it. but will also consider what noob said about losing output at far off frequencies.

Joe X Posted June 19, 2012 Report Share Posted June 19, 2012 To the very least you should be using a 6" aero. Quote Link to comment Share on other sites More sharing options...

Joe X Posted June 19, 2012 Report Share Posted June 19, 2012 As a single port solution I meant to say but two 4"s would be another option. Quote Link to comment Share on other sites More sharing options...
98GCLimited Posted June 19, 2012 Report Share Posted June 19, 2012 (edited) x2 add another 4" aero or get a 6" aero and run that Id do the single 6" aero its got a little more area than 2 4" aeros and I just like one single bigger aero when possible vs multiple smaller ones.
