I have an alpine type r sub and I am looking for to make the smallest box possible with a good response between 25 to 45 hz. I am interested in building a double folded ML-TQWT since have an appreciation for quick transient response. To me ported and sealed produces "box colored" bass. I have looked at hornresp but it seems complicated to use. Any help will be appreciated.

Alpine SWR 1042
Qes 0.57
Qms 7.92
Fs 33
Qts 0.53

SPL @1W/1m 83db
Xmax 18.2 mm

Thank you

Did a ML-TQWT, ML-TL and TQWT with all around 166 L and having near enough the same impulse response once damped, though markedly different frequency responses. Note that the damped sims can only be viewed in the Loudspeaker Wizard.

Download the files into HR's Import folder and open them to save, then copy to make new files for altering if desired.
