Hello experts. I am learning how to use Hornresp and think I finally have a grip on how it works, at least enough to load a driver, select the enclosure, and mess with the shape and size of the enclosure. I am trying to model a TQWT and MLTL to see if a concept I have is possible. I am unfamiliar with those designs but wanted to venture beyond sealed and BR. I am building a 2-way loudspeaker so the woofer will need to play smoothly up to its crossover point. As I mess around with the cross-section areas, lengths, driver placement, and stuffing, I can't seem to get rid of the (what appears to be) harmonics. If I were building a subwoofer cabinet, I wouldn't care because all the ripples would be above the cutoff frequency.
My actual questions are:
Is Hornresp displaying the predicted response accurately or is the ringing showing up on the graph just noise above a certain point?
Should I be able to see a relatively flat response graph like I would with Winisd?
Are harmonics a function of these types of enclosures?
Is there any other software besides Hornresp to model these types of enclosures?
Thank you in advance!

HR doesn't include any acoustic damping, so you're seeing a 'perfect' set of eigenmodes that you can deal with in the LW.
No, you'll see a much more accurate response in HR with/without damping whereas a basic T/S program assumes a ~uniform particle density and from long experience have learned that a smooth looking TL, etc., is way over-damped for the majority of folks to the point where quite a few have pulled out most/all of the suggested densities from the few advanced programs I've used, so finally quit suggesting any beyond the pioneer's basic one side, top, back to 'taste' 😉.
Yes: Air Column Resonance
There's other programs with MJK's the best one I know of no longer available, so with HR nowadays matching up well with it see no reason to look further.

Thank you for this. It definitely clears up what I see on the graph! And also thanks for all the additional information!Greets!
