Opera Centrale 2012 is the central channel of the “Classic Line”, “Callas Line” and “Lirica Line”. It is a two-way speaker about 12 liters, TEB loaded, that can be used on a stand or shelf. It uses the same components of the Mezza. Opera Centrale has a very smooth frequency response, high sensitivity and good voice and is ideal for use in combination with all the Opera speakers. The cabinet is made with MDF shaped MDF with rounded corners, lined with leather. The leather, in addition to the aesthetic function, ensures airtight for the loudspeakers. The front side of the Centrale, such as traditional for Opera, is wide enough to accommodate the speakers for optimum vertical dispersion and excellent transient response. The volume of the cabinet is filled with a good amount of absorbent material that controls the Q factor of the cabinet and minimizes internal reflections. In designing the Centrale, particular attention was paid to electrical impedance of the speaker. In particular we wanted to ensure easy loading condition for any amplifier. To achieve this the minimum impedance were kept within the limits of DIN: the minimum impedance of Centrale is always greater than 6 ohms. The cross-over of the Centrale uses a classical topology with slopes of 12 dB per octave. The transition frequency is fixed at about 2300 Hz and the sensitivity is about 90 dB (2.83 volts at 1 meter). Opera Centrale has been designed to be placed on the shelf or on a stand (available on request) and it can be positioned above or below the screen (plasma or LCD). In any case we do not recommend placing the speaker too close to corners of the environment. With the speakers on stands is recommended to maintain a minimum distance of 30 cm. from the side walls.
