1
Coverage angle is the -6dB average. All measurements made at
24 inches and confirmed at 6 feet (on-axis except where noted)
using pink noise source and measured in
1
/3rd octave bands.
2
This configuration produces smooth response, but is asymmetrical
in the vertical plane. (Measurement axis same as for a single UPA-
1C).
3
Frequency response 50Hz – 16kHz, half-space conditions.
Note 1:
Measured 1 meter from center
of cabinet face, half-space
conditions, pink noise input,
network set to FLT, smoothed
to one-third octave. Low
frequency response dependent
on load conditions.
Note 2:
Loudspeaker driven with pink
noise.
