From the Opera web site:
The new Callas speakers use techniques and components that represent the state of the art in electroacoustic, starting rom the cabinet, the speakers and the crossovers.  The result is tonally correct, realistic, engaging, and above all enjoyable to listen to.  The new model Callas is an example of elegance and fits discreetly into any environment.   Callas 2014 is a compact two-way loudspeaker of medium-small size which can be placed on a shelf or a stand.  Its main feature is a low frequency response, extended and controlled, combined with a typical sensitivity of floor standing speakers.  The woofer is 7 inches, long-throw, with annealed polypropylene diaphragm combined with the Scanspeak 9700 tweeter (the same tweeter used for Tebaldi, Malibran, Caruso and the new Grand Callas 2014).  The woofer is reflex loaded with a rear duct.  Great care has been placed in the elimination of the internal reflections to ensure maximum transparency in the  voice reproduction.  Callas 2014 is equipped with a switch that allows you to adjust the output of the vocal range (+2db between 300 and 3000 Hz.  This increases  greatly the flexibility of the diffuser that fits both to a greater number of environmental situations. The new Callas produces a sound stage that expands in three dimensions with an excellent impulse response and power, dynamics and extension at low  frequencies typical of systems of much higher dimensions. This speaker is also  suitable for the near field listening (up to one meter to the listening point).
