Gold Member Username: Sinful_systems7015 INCH WANG... Post Number: 1083 Registered: Nov-06 | Have done some research on these and found out that alot of people didn't like the 6" port saying it was too big since the it flares to almost 9". Just what I have heard, but I did a calculation with (2) 6" at 9.64 long to save some money since they are $40 each!!!! |
|
Gold Member Username: Tremor1127Fi Post Number: 2584 Registered: Aug-06 | two 6" ports. is that enough port area? |
|
Gold Member Username: Tremor1127Fi Post Number: 2585 Registered: Aug-06 | repeat... |
|
Silver Member Username: Talon0112 audioque 2.5 145.2 ..., Pa Usa Post Number: 600 Registered: Jun-07 | i am at work if no one answers then ill check on the calc. after work, i think it will be ok but i want to check first |
|
Silver Member Username: Talon0112 audioque 2.5 145.2 ..., Pa Usa Post Number: 601 Registered: Jun-07 | looks like you'll have some port noise, 2-6" is just under min. area i would do the 6-4" |
|
Gold Member Username: Tremor1127Fi Post Number: 2586 Registered: Aug-06 | cool, yeah, im no genius when it comes to the calculations i just hate screwing stuff up... |

Gold Member Username: Tremor1127Fi Post Number: 2587 Registered: Aug-06 | "looks like you'll have some port noise, 2-6" is just under min. area i would do the 6-4"" oh ok, dang, i was typing while you were... well thanks, it will be that if he does aeros. i may cut it all in half and try my avalanche in it since i dont have a design for it yet... |

Silver Member Username: Talon0112 audioque 2.5 145.2 ..., Pa Usa Post Number: 602 Registered: Jun-07 | cool give us results if you do |
|
Gold Member Username: Sinful_systems7015 INCH WANG... Post Number: 1096 Registered: Nov-06 | I was just trying to figure a way for it to be cheaper for him!!! but yes, it would be better with 4. JMO |
|
Gold Member Username: Tremor1127Fi Post Number: 2588 Registered: Aug-06 | oh i hear ya man. i actually think he is just doing slot port though but i was about to try a box or two with aero ports myself. and maybe a few more if i like them. the few aero port boxes i heard sounded good. they have their own sound sorta, im thinking... |
|
Gold Member Username: Tremor1127Fi Post Number: 2589 Registered: Aug-06 | are you guys using a calculator of some type to check if there is enough port area? |
|
Silver Member Username: Talon0112 audioque 2.5 145.2 ..., Pa Usa Post Number: 603 Registered: Jun-07 | 2 6" 80.00 6 4" 75.00 48sq in 96sq in of port |

|
Gold Member Username: Tremor1127Fi Post Number: 2591 Registered: Aug-06 | ok, heres the box i wanna do for the 18" avalanche... 6.5 tuned to 28hz. three 4" ports. it says, "Straight Length Port required 17.01 Flare Length Port required 18.01" im using PVC so no flares at either end. should i make the PVC 17" even? ill prolly do 18 and cut if needed... |
|
Gold Member Username: Tremor1127Fi Post Number: 2592 Registered: Aug-06 | and three 4" ports would be like 70+ sq in of port versus 48 sq in or 96 sq in... |
|
Silver Member Username: Talon0112 audioque 2.5 145.2 ..., Pa Usa Post Number: 609 Registered: Jun-07 | off the top of my head i thought 4" round was 16sq and yes 17" long you add 1"for the flare correct |
|
Gold Member Username: Tremor1127Fi Post Number: 2593 Registered: Aug-06 | no flare at all. straight pvc pipe glassed to the box. what would be better for my box if thats not enough port area... |
