Well, that's one use for a surplus M113

I don't need any proof that people have degrees, I need proof that people have the knowledge about the subject they are talking about. I know people that have a electrical engineering degree, but after they got it they barely know the difference between a diode and a transistor. Port volume is related to tuning, since tuning is specified you can't alter it, so the only thing you can change is the port area. You are right, but worded it illogicaly.

Fucking Cowboys giving me a heart attack

I finally finished my framing, here is the area where the baffle is going to be built. The woofers will face down and be about 2" above the drywall. I will make a large grill frame and cover it with white grill cloth. The amplifiers will be upstairs and the subwoofers will fire through a heat register...

Lmfao thanks for the negs!!!

Uh yes I am very aware of that..lol cool, i was getting tired of correcting you. OMG.. ....

Email shizzzon for answers for taramp. He won't steer you wrong.

No disrespect brother...But I studied this field for years.. ummm shit posting is meant for the hop. Ummm I am out of hear I am tired of getting disrespected by a few of ya'll and criticized on every post I make..Way to run people off..congrads

No disrespect brother...But I studied this field for years.. Then give arguments that are based on facts and can be checked. (maybe even provide a source while you're at it.) How are Octogonal ports ever going to give more port area that the same size circle, not to mention a square port. EDIT: yes, I actually made this in paint. That is a pic of surface comparison .. Volume I guess that would depend on the desired frequency as you have to figure in the Length of the port walls as well.Correct?

Air velocity was more the factor than "cosmetics" and less port noise VIA "more port area" with the octagon ports.. Port area is what you said. Air velocity was more the factor than "cosmetics" and less port noise VIA "more port area" with the octagon ports.. Port area is what you said. Well maybe I should have said volume You know what I was getting at Smaller the volume faster air travels..Larger volume slower the velocity is what I was getting at.

"For example" Moving air from "point a" 100ft to achieve the same CFM at "point b" at the end, You have to reduce the volume/area to keep your desired speed. larger volumes for longer distances loses speed And IMO would create less unwanted noise..

The speed of air does effect unwanted noise....More port volume slower the speed so that does not mean less port noise?

The speed of air does effect unwanted noise....More port volume slower the speed so that does not mean less port noise? think of it like using a larger gauge wire (more current), larger port area results in lower air velocity. That results in less unwanted noise.correct?

Well maybe I should have said volume You know what I was getting at Smaller the volume faster air travels..Larger volume slower the velocity is what I was getting at. air speed is related to the cross sectional area not volume. No No read up... the distance has to be calculated as well "for example" for you total..If you would like I could snap you a pic of my degrees in this field. http://www.dwyer-inst.com/Products/AirVelocityIntroduction.cfm

That results in less unwanted noise.correct? larger area -> lower port air velocity -> less air turbulence/chuffing Ok.. so are you agreeing with me or not..Lol

Uh yes I am very aware of that..lol
