Excellent information, thank you all!

I played around with HornResp a lot and I think I found the optimal first build for me. It seems to have respectable response, reasonable tolerance to parameters and way simpler to fold than a T-TQWT. You know, one can always build another subwoofer

Attached are the data and simulated graphs, any comments are welcome, I am one phone call from ordering the panels for this horn.

BTW I do have a DCX2496 at hand, which makes adding a steep lowpass and/or delay trivial.

Hi wxn,

Your example in Post #12 is a typical T-TQWT (in Hornresp you use TH to model this), the folding depends on the final form factor you want to achieve. Looks good to me.

I'll attach a quick comparison of your driver in T-TQWT (40.5L) or TH (126L).

Regards,

Ok, thanks for the clarification, the terminology is a bit confusing so someone like me
