Dear all,
I am brainstorming again, looking for some sort of protection for the 3" fullrange units SB10PGC21-4. If I am going to put something in front of it, I thought about adding something that could improve the CD of this speaker, specially at HF
I saw some speakers and experiments that use a phase plug sustained in front of the driver, and I was thinking about using our lab 3D printer to make some prototypes. I just made a rough sketch on this nice Friday afternoon, but it is too late now to turn on the printer and have this ready before going home 🙂
But, most important, can you recommend me any literature on this?
many thanks, Erik

In my experiece, the important thing a phase plug does is the removal of th edustcap and the elimination of the soup can resonance inside the voice coil.
Yours is more like those used on some tweeters. I have seen (and heard) some where this has been clipped off for an improvement. On a small driver, it is often not an issue.
Your proposed design is non-invasive, i look forward to hearing how it turns out. You will have lots of shapes to explore.

Thanks for the reply Dave!
I am thinking about a line array with these drivers, and had the idea of directing the HF content in the horizontal plane: 1 - avoid/less combing effect of HF in line arrays and 2 - have a bit more HF in the desired horizontal plane. But I think this will require a lot of experiment 🙂 🙁
I found some threads taling about dispersion tricks, do not apply to HF however.

slot over speaker to offset increasing directvity?
thanks again!
