Hi there, could somebody help with checking this box design I did for the above Satori driver using the Boxplan-TQWT spreadsheet?
I tried to export this design into Hornresp but found it too tricky to extract some meaningful information.
I'm not looking for suggestions for a different type speaker design, I only want to make sure this works reasonably well.
I like this particular type of TQWT fold, where the tapered end is folded 'behind' the driver towards the back rather than the other way round.
One question I've had: this design appears to have a distinctive 'port (S5), whereas I've seen other designs where this is simply an opening. Anyone care to explain why?
Cheers

How very strange. Only this morning, I was reading about an acoustic patent application in volume 37, issue 12, October 2024 of Voice Coil magazine that is quite similar to this design! Wanting to know more, I started to search here at DIY, and this thread is the first that I encounter. In the description the design was actually for a transmission line that also makes use of a port in the lower octave. I see that what you have looks to be a tapped horn design with a port of sorts? I find either of these ideas intriguing though seemingly experimental, at least to me.
Intrigued as I am about all of this, I can only stand aside, waiting for someone to comment. So glad that you have brought this forward.

As far as type is concerned, all perfectly standard & been in use for decades I'm afraid. How in the name of sanity some of these patents get through I don't know, since to put it mildly, 'prior art' is in effect. 😉 They're normally called ML-horns, TQWTs, Voigt horns, single-tapped horns etc. -folded, as shown above, to fit into a regular rectilinear box form factor, which in most cases makes them fairly redundant since a simple MLTL will usually do the job as well or better, with less complexity. YMMV as always of course.
Thanks. Surprising about the patent application.
I'm aware this is an old hat, and that a simple MLTL might be doing the job just as well.
However, I was just looking for constructive feedback on my particular design, not suggestions on what type box might work better.

Yeah, 'we' really got carried away with the variations, though 'tapped' isn't even close to being one of them.
Ah! Though seems like we historically just called them offset?
🤣
