rl1856 Posted May 17, 2020 Report Share Posted May 17, 2020 I understand the 211003-1 tweeter is from the KK designed AR303 series. However I find few references to this tweeter in forum archives, and one reference on the last page of the AR3a restoration guide. I re-read the Stereophile review of the AR303. Overall FR sloped downward, with treble response noticeably less than MR response. However, treble dispersion was reasonable, holding up well to 10khz at 45-50' off access. Subjective comments noted that in room dispersion somewhat compensated for the declining on-axis response slope. I would like to find the electrical characteristics of this tweeter; sensitivity, impedance, FR, dispersion characteristics and of course opinions from those who have experience with this tweeter. Thank you ! Quote Link to comment Share on other sites More sharing options...
