This have the best stereo width and depth of field from all speakers i hear. Seem because the group delay have few diffrences. there is a gap at 10 khz when it is around 15 degreee offaxis hear it get more. the group delay i have measure at 8 cm distance because only below 12 cm it give correct results. because its coax can put near. the FR is measure from a distance of 50 cm in my room. be near on the speaker help alot to reduce room reflection influence. see the RT60 decay between 1 meter and 50 cm. i have output volume on the speaker same and microphone record 6 db less.
