Bill and friends does anyone have an idea how to model triangular ports?
I see bill sells plans for the simplexx with triangular ports but I can't support him this time because this is for a 4th order bandpass
design.
I'm also thinking of adding a quarter wavelength resonant trap to the vent.
Anyone have thoughts on this?
Here's a project showing the trap

Re: triangular ports
Well, you see.....the triangle port on the Simplexx adds a coherent phase coefficient of a value equal to the ratio of the driver diameter to the cubic volume of the lateral inverse dynamic of the subsonic wave.
....and a partridge in a pear tree....
I have no clue what I said.....of course, I'm not even smart enough to understand the question.....

Re: triangular ports
Well i have winisd and that can model square and round ports but wanted to try triangle ports. How do i calculate the length and how much does proximity to the side wall and or floor effect the tuning?

Re: triangular ports
A triangle port models the same as round or square. What matters is the area, not the shape. The sidewall doesn't affect anything. I tested them and compared the results to round ports mounted in the middle of the baffle. No difference.
