Fairly even coverage on both axis. Horizontal has some minor waistbanding centered around 1.4 kHz but is otherwise very even holding around or just above 90 degrees over most of its range. Vertical directivity is also very even over most of it's range a little wider then it's rated 60 degrees to just over 10 kHz.
