The two-way biamped model 42.12 (2x12", 1") delivers a combined power output of 400 W/RMS. Class H amplifiers which are well-proven to produce high efficiency with low ambient temperatures, are the power source for this series.
Employing a specially developed built-in wave guide with Constant Directivity horns combined with B&C 1" compression driver, an accurate clean dispersion characteristic of 90º x 60º is achieved.
To improve the bass range of the OPERA Series we have developed an active 18" subwoofer. This unit can be used in combination with any of the Active or Passive loudspeakers in the OPERA Series. The 18" BNC driver is powered by a 600 W/RMS Class H amplifier and develops 130 dB SPL.
