Maximizing cabinet efficiency

it still rings at the ‘3/4’ resonace. It’s still intersting to investigate how these function and understand how to design and construct them using horn response details (not just frequency response) to consider issues to avoid and why. This stuff is exciting!
 
Why don’t you just turn off the crossover and play test tones surrounding that frequency and see what you hear ? Maybe your very small exit, crossover settings and low volume prevents this from being audible(which woukd be great info and very good to know after you recognize the resonance ). I don’t have such a small exit on my TQWT s…

My exits are at least 1/3 of Sd.
Any ratio above 3:1 is small.

I do run 120hz low pass in my car, but at -24dB...-12db from the head unit and -12db at the sub amp.

In the house, the T-TQWT is running these settings...

It’s easy to remember those numbers so I use it to ‘design’ qw resonators. But the sacred geometry/numerology rabbit hole is for the skitzophrenic🫡

set the speed of sound to 345.6m/sec in horn response and (the radius of the sun 432,000 miLes 🤡) 43.2 hz is 2 meters.
