Port compression in TQWPipe?

I drove this thing until the former bottomed out (oops)….

Would port size issues and turbulence show up in a way I could recognize it with this measurement(s)?

A simple test for turbulent port flow:

You can also see turbulent port flow in impedance measurements done with increasing voltage levels (take good care of the measurement resisor!). The "tuning" will get higher once the laminar flow is disrupted:

a big nope lol... It looks like... as the measurement gets louder, Direct sounds dominates the measurement more for whatever reason, the hair leaves the FR and the GD lowers since you are getting less of the room in the measurement when it was loud. Also, take with a grain of salt as with most measurement predictions lol

This is super intersting!

That naming junk is so old and worthless…. Confusing….


They are all 1/4 wave resonators with various shapes that create more/less high frequency junk that limits the bandwidth.

Tqwrtlgbt doesn’t really help describe much ?
It's junk and worthless to YOU because it's confusing to YOU.

True, they are all QWR's. However, the mounting position of the driver and the flare rate changes the enclosure type.

Mount a driver on the outside of a Tapped Horn, then you have a Transmission Line. You went from a 6th order to a 4th order enclosure. We already discussed what happens when you swap the throat and mouth of a TH. You go from an efficient and big enclosure to a low and small enclosure...Hofmann's Iron Law.

BTW, bjorno named the negative flare TH, T-TQWT. Bjorno was a modeling BEAST on diyaudio.
