I've been having serious quality control problems with a certain ribbon tweeter I'm using in several commercial designs, and I'm trying to find a suitable replacement with more consistent measurements. I ordered a

NeoCD3 to test, and found the frequency response a fairly close replica of the factory plot. I couldn't find an impedance plot (and didn't see one on Zaph's site either), but it's listed as 7 ohms. Mine measures about 9 ohms. Has anyone else measured impedance on these puppies? Thanks.
