Saba Greencone frequency response graphs

[super011]

Hi diyAudio community,

Does anyone have Saba Greencone 4" & 8" frequency response and impedance graphs? I'm looking for FRD & ZMA files.

Thanks in advance!

FRD and ZMA plots for those ancient Saba Greencones are way beyond my ability or measuring equipment.

But Mr. Troels Gravesen has done a bit of work on them:

Hope it helps. 😎

Try it out. Maybe you won't notice the absence of anything below say 180Hz...

Perhaps those statues are hiding a subwoofers in the base 🙂

I might be able to dig up some SABA measurements. I remember them being rather ugly.
