To improve the bass range of the OPERA Series we have developed an active 15" subwoofer...
This unit can be used in combination with any of the Active or Passive loudspeakers in the OPERA Series. The driver is powered by a 400 W/RMS Class H amplifier and develops 127 dB SPL.
As an ideal complement to the active OPERA models or even the STAGE OPERA 42.12, it offers high sound pressure (127 dB max.) with powerful bass down to 30 Hz.
The housing constructed of 20 mm poplar multiplex, painted with black textured paint, along with the highly efficient class H output stage is mainly responsible for the extremely low weight of only 24 kg/ 43 lbs and thus the extreme ease of handling. The integral active diplexer separates extremely precisely, and is phase accurate, with a slope of 24 dB/octave at 100 Hz and can be operated in both mono and stereo.

The connection panel provides a high level of flexibility with its two balanced Neutrik Combo XLR / jack inputs, two XLR parallel outputs and two XLR diplexer outputs. The integral soft clip limiter protects the system from overload and allows the cleanest reproduction even at the power limit.
Like all dBTechnologies active subwoofers, the integral fan cooled output stage has a totally enclosed output stage compartment to isolate it from the loudspeaker enclosure.
