Hey Rob, so tell me why an angular port is bad, such as this enclosure here:

View attachment 67674

Why would someone not use a round port for this? Do you know what this type of enclosure is called? I've actually designed one of these before for a vehicle although with a different layout.

The one I designed (customer built):







And it's still a wavelength based line but mine isn't flared the same way but it's a lot of the same math, same concept applied slightly differently.

So maybe you can explain to me why me and like every horn and line builder ever is wrong. Can't wait to be enlightened.

WTF is your problem? Clearly you should buy a shyt ton of PVC pipe to construct those enclosures. Or perhaps make your tapered lines with fiberglass. Construction challenges aside, last I checked wooden angular ports function just as well as round bent ports. There maybe some rare instances where I'm super cramped on space and might prefer round over slot ports, but that would a rare case indeed. There is a reason for the popularity of slot ports.

I know man I'm such a moron for using angular ports to help people win comps and break their windshields and relieve stress after a hard day of work. I need to make my boxes look like the plumbing under your house

And you are correct bass waves are so long you have to fold them, and doing round tunnels are impossible to use in many instances. It all comes down to just knowing what you're doing. I could make triangle ports work, but it would be inefficient. Round ports are the most efficient due to surface area inside of port vs radiating area, round ports have least internal drag.

There is no "style" of port where right angles are good, when it comes to fluid dynamics.

Did you bother to read the two papers I linked to?
Do you think they are somehow fake information written about just to make your designs look bad?

"Some simple similarity solutions are presented for the flow of a viscous fluid neara sharp corner between two planes on which a variety of boundary conditionsmay be imposed. The general flow near a corner between plane boundaries atrest is then considered, and it is shown that when either or both of the boundariesis a rigid wall and when the angle between the planes is less than a certain criticalangle, any flow sufficiently near the corner must consist of a sequence of eddies ofdecreasing size and rapidly decreasing intensity."

Written in 1963, only to make Buck look bad on a car audio forum at some point in the future.

No, I didn't read them, because you don't understand box designing and building. Go ahead rob, show us all the boxes you've designed and/or built

I could have swore that a few pages ago, he said he isn't some sort of master box designer. I must have misread that.

At one point he described himself as the best in world.

So you think fluid dynamics changes bsed on your lack of understanding for them?
That's like ThxOne calling an autopsy "gibberish" or the CFR "bullshit" because he doesn't undertsand what he is reading.

You a funny man.

Just because slot ports are popular doesn't mean they are better.

I'm not even talking to your stupid *** and you are taking jabs at me. How much more proof do you need to show you are here just to bash people?

I just think you're mentally ill and not handling it well.

If you don't want anyone to know your beliefs, maybe you should stop posting them here.

That doesn't speak to your lack of understanding for some basic concepts of fluid dynamics.
Let's stick to that topic, and then we can discuss my mental well-being.

What makes you think a square port is better than a round port for airflow? What makes you think right angles in a port are better for airflow than curved surfaces?

Dude, you don't know what you are talking about. You're literally showing everyone that you've never really done that much audio ever. Round ports are more efficient, yes turns interfere with air particle and wavefront flow, but you don't understand most boxes can't use round ports and ports with no turns due to complexity and layout dynamics. Stop faking audio knowledge with lame *** searches that you pull out of your ***, you can smell the through the screen lol

"Can't", or "won't"?
Sorry, that doesn't make it better to not have round ports.

Completely disregarding that ports are a compromise in quality to begin with, the laws of physics do not bend to your whims.

Well, good luck everyone else. This retard is full blown
