Hygeia RT-2002/20051 AMT Air Motion Transformer Tweeter - One Pair - IMPROVED!

Description

Hygeia RT-2005 AMT Air Motion Transformer Tweeter PAIR - now with modified diaphragm for lower distortion performance!
Please see the pictures for actual screenshots from my Dayton Omnimic.   Measurement SPLs were not as high as the charts show - they show high because the microphone was placed close to the tweeter, about ≈3", for accurate HD measurements (to prevent reflections from appearing in the graphs).  3rd order distortion is greatly reduced.  Also these measurements are with approximately 7-10W of input power, which produces deafeningly loud sound (had to wear earplugs & ear muffs for these tests even though I was 6 ft away).  Under typical listening levels, the average THD of these tweeters will be very, very low.
