Im doing a ML-TQWT simulation with Mathcad worksheet ML TQWT.mcd.
Is it possible to simulate with for an example 10*12" at the bottom and 6*8" at the top?
Another question, is it possible to change from inch to cm?

At a glance it looks fine except the sim doesn't match your original dimensions/shape, but haven't used the later worksheets, so best to ask at his FB Grp.

You mean the numbers in the first post? Thats just an example 🙂

Looking at your attachment, that is not a TQWT.
TQWT can have 2 meanings.
1. Tapered Quarter Wave Tube or basically the whole enclosure is a negative flare port and the speaker is mounted on an external panel.
Positive flare = Back Loaded Horn.
Straight flare = Transmission Line.
2. Tapped Quarter Wave Tube or a straight flare tapped horn where the speaker is mounted on an internal panel.
Positive flare = Tapped Horn.
Negative flare = Tapered Tapped Quarter Wave Tube.
Here is my T-TQWT.

Per MJK he has a positive flare vented [ML] TQWT whereas me and some others prefer to further define them as ML-horns. This disagreement with him was one of the reasons he left the forums.
Yeah, I made the mistaken assumption that by using his software that he was familiar with MJK's site where both FB links are prominently displayed: Quarter Wavelength Loudspeaker Design

But his constant pointless name game nitpicking and unfortunate ..(since then slowly the ‘horn’ word became less of a pet peeve...but too late and the clash of the titans could gave been the brainstorming or two well equipped brain powers( fact, not brown nosed 🙂 .), is a shame. Because to anyone whos messed around with the top pictured, its clear what that can and is able yo uniquely give unit a hornlike name. Put a hivi 4”b4n in there and its akwardly at 40hz Fb and its a bit serious about making sure you cab hear it. mass loaded sensitive with an attitude mini monster horn shaped expanding path TL , whatever! But more importantky Mr King, sir. Its a great design for some legitimate and real reasons..

Is restricting a positive flare mouth equivalent to a trumpet having a mute?
Hey?!?? Thats a bit too much to deny theres not a great idea in that 😱😱 i mean,if you see what i see, then i say theres the little tapped and strapped horn for the next build?

Closest would be the harmon mute.
