Acoustic Horn Design – The Easy Way (Ath4)

What woofer size? I have some 18sound 8NMB420 that need a new home

This is 6.5", 210 mm baffle width. Starting with the smallest feasible.

So, something like an SB17 chassis? Cool! My printer is good for 220 mm, so I'd be right there.

Are the A400G2 files in cult3d available as a segmented design?

 

[mabat]

No, I don't think I've made those for the 400G2.

Sure, anything of that size, it's just a matter of different cutouts (STEP file without the cutouts will be available).
I'll be making a full design with Dayton SIG180 (not sure about the HF driver yet) including the crossover etc.

I like the idea of adding just a simple box to the printed parts. This can be done in a kitchen 🙂
