Malibran is the first loudspeaker system designed by Opera and produced by Unison Research. It is named in homage to the great 19th Century soprano Maria Malibran, whose remarkable life and talent was cut short at the age of just 28. She is remembered today as a legend in Venice, where a Theatre is named after her. This loudspeaker incorporates all the important technical solutions and innovations developed by Opera in recent years, including the inward-firing sub-bass section, the progressive low-pass filter, the Cross-Linked Dipole rear tweeter array and the TEB (totally enclosed box) with sealed enclosures for each bass driver. The Malibran cabinet and is made up of an inner cabinet of multi-layer plywood and thick MDF, with an outer layer of finely sculpted and highly polished real wood. The overall volume is 146 litres and weight is 120kgs, the whole structure being virtually inert and resonance-free. Wheels are fitted for easy movement. Although there are 12 drive units in total, Malibran is in reality an extended two-way system, with powerful passive sub-woofer and cross-linked dipole radiating system all in the same cabinet. Its particular design makes it easy to use in any room, whether large or small. Driven by suitably capable amplification, the sound is totally convincing.
