Boogie Knights Posted August 1, 2010 Report Share Posted August 1, 2010 I was just wondering if my measurements/math is right.. I've got a box its 14Hx27Wx32L it has 5cuft after all displacement. (2 12" subs, 2 6" aeros) tuned somewhere between 37 and 40. Now if I were to cut 2" off of the length of the box I would get 4.24 cuft after displacement. And it would be tuned between 30-33hz For 2 12" subs the displacement is .28 For 2 6" aeroports the displacement is .52 Does that seem about right? Thanks in advance..

Thanks in advance.. it would tune higher if you make the box smaller and keep the same size port. what i would do is sell the box for about $60-70 and build a new box My Car Audio Setup: Sub: 1 RE Audio HC 15 Dual 2 ohm(soon to get a psi recone) Daily Sub Box: 1.62 cubes net with 2 dayton audio 8 inch passive radiators tuned to 34.35 hz, 141.9 @ 48 hz sealed on the dash with termlab Competition Sub Box: 3.10 cubic ft. net tuned to 50.58 hz with 2 6 inch aeroports, 147.9 @ 62 hz sealed on the dash with termlab Amp: Powerbass ASA 1000.1 Dx(eventually gonna get a planet audio bb2400.1) Big 3: Phoenix Gold 1/0 Gauge Amp Wire: Knukoncepts 1/0 gauge Alternator: Stock 90 amp Battery Under the hood: Autocraft Gold Top Battery Battery In Back: None for now but I am looking for one so pm me if you have one for sale HU: Pioneer DEH-2900MP Front/Rear Amp: Hifonics Txi-4408 4 channel amp Front Speakers: Orion Cobalt 6.5 coaxial Rear Deck Speakers: Orion Cobalt 6x9 coaxial Home Audio Setup: Speakers:2 Cerwin Vega D-3's (10" Woofer,5 1/4" mid-range,1" Bullet Dome Tweeter) 2 Cerwin Vega D-5's (12" Directed Audio Xtreme 124SX Subwoofer,5 1/4 mid-range,1" Bullet Dome Tweeter)Kenwood center channel and rears.

Boogie Knights Posted August 1, 2010 Author Report Share Posted August 1, 2010 Really? Well now I'm confused. I checked the aeroport calculator and its telling me that I would be tuned at 32hz. It says I would need 33" of length. Which is roughly 2 6" aero's since they're like 17" long each. Or am I missing something here.. I hate math..
