Acoustic Horn Design – The Easy Way (Ath4)

[kodomo]

I have downloaded the files from cults 3d but I have a question. There are three jigs, why is that? I will get this printed in professional 3d print store, which file should I send.

Also for the extensions, which flange is the right one?

ps. I bought the La Voce CD driver!

Regarding a final absolute SPL curve, a lot depends also on a waveguide, so the picture above only tells you that the driver per se is probably smooth enough to work with easily, but not much about a required EQ in a particular horn. But I'm not convinced that a stronger magnet is necessarily an advantage here. It can add a few dB of midband sensitivity (which is already pretty high anyway) but not always improves things regarding EQ.

If you look at the DF10.171K with the A520G2, there's already very little that needs to be done. But of course if anyone tries the other variants of the Lavoce drivers, it would be more than welcome.

I was primarily concerned about the initial rise and sudden drop from 18kHz to 20kHz on the DF10.171K (if that's even audible), rather than the absolute SPL. The DF10.172M appears smoother in this region.

The DF10.172M appears smoother in this region.

I tend to not take datasheets at face value to this level of detail, but it may be indeed smoother.
I would be surprised if it was noticeably better in the top octave (than all the other very similiar ones), but all I can say is try it...
