Autruche Posted September 29, 2010 Report Share Posted September 29, 2010 (edited) I have a bit of a conundrum here. I am building a box for two 12s for a friend, he wants it tuned to 32hz, and I want about 45 square inches of port. the box will be 24 inches deep, and one port would be either 30x1.5 and 21 inches long, the other would be 14.5X3 and 25 inches long. I want to do it subs forward port forward, but in doing so the 14.5x3 port would need to turn, and i want it in the middle, so it's a no-go. Or I could do two 14.5x1.5 ports, one on each side. I guess my question is what port would you prefer? 30.5x1.5 14.5x3 two ports, each 14.5x1.5 I know can figure it out, but I just want some input from more experienced members for future reference.

I thought about that too, but you don't see too many people with multiple thin ports..you see one big one Quote On 5/8/2011 at 7:38 PM, Kranny said: On 5/8/2011 at 7:35 PM, 'Maxim' said: It hurts me inside when I read stuff like this and remember you're 15 LMFAO so true Mitsubishi 3000GT (Old Build) Headunit: Pioneer 80PRS Frontstage: (2) McLaren Audio MLT-2 Tweeters & (4) PRV Audio MR Series Neo 6.5" Mids Substage: 4 15" Hybrid Subs - Tantric Motors & Sundown Softies Amps: Banda 2.4D Amp (Tweets), American Bass VFL 350.4 (Mids), and (2) Ampere 3800s Electrical :Singer 260A Alt & JY Power Lithium 2005 Chevy Colorado Ext Cab Headunit: Pioneer 80PRS Frontstage: 4 PRV 700Ti Tweets & 6 10" Delta Mids on 3000wrms Substage: 6 Fi BTL 18s in a 4th Order Walkthrough on 3 Wolfram 4500s Electrical: Singer "390" and JY Power My Official Feedback Thread Link to comment Share on other sites More sharing options...

Ji553r Posted September 29, 2010 Report Share Posted September 29, 2010 (edited) the bottom pic would take a bit of wood and more precision since your doing 2 ports. thats all i can really input other than my opinion of just the one big port at the side Edited September 29, 2010 by Ji553r Quote I don't fuck around.

MarioB Posted September 29, 2010 Report Share Posted September 29, 2010 im pretty sure you can port it down the middle and make it slip to each side in the back but i may be wrong.

Autruche Posted September 29, 2010 Author Report Share Posted September 29, 2010 Single side port on drivers side That's what i'm thinking, I'm just not into the way it looks, but I guess you can't always have it all, lol. im pretty sure you can port it down the middle and make it slip to each side in the back but i may be wrong. I want it to be a common chamber box, and that would split the box into two chambers. Quote Need Test Tones/Sine Waves?
