Measurement Notes:
Frequency range constitutes the usable bandwidth after on-axis normalization with the CP-10. Coverage angles measured as the -6dB(1/4 power)points from the normalized on-axis frequency response averaged over the band from 125 to 8KHz. Maximum SPL measurements made under half-space conditions. All measurements made at 4 meters using pink noise and measured in 1/24 octave bands with SIM System II.
Amplifier:175-350watts @8ohm FTC rating.
