Hi Folks, I recently developed a replacement Diaphragm for Blown Infinity EMIT Tweeters. For a direct comparison I did FFT measurements on 4 Tweeters; two Infinity EMIT’s, and two with the new Diaphragm. Test was performed in a custom made 1 Meter Anechoic chamber with a Mini-DSP UMIK-1 calibrated microphone using Audio Tools FFT Software. Pink Noise was used as an input signal and was powered by an Adcom 565 Amp and fed through an Infinity Kappa 8 crossover with all controls set flat. Here’s a Graph showing the 4 plots, as you can see they measure very close to the originals.
