Manufacturer: Opera Loudspeakers

While designed in the same style as Opera's most affordable loudspeakers, the Mezza, the Grand Mezza is far from an "entry level" speaker system. Opera worked to produce a quality speaker that's suitable for normal home use with low- or medium-power amplifiers starting from 10-12 watts RMS, such as the sister company, Unison Research's, range of valve amplifiers. Though designed with Unison Research valve amplifiers in mind, the Grand Mezza are also easily capable of handling more powerful amplifiers (up to over 200W RMS per-channel), provided the amplifier is of good quality and is protected against excessive clipping.

This latest version of the Opera Grand Mezza was released in 2012, and compared to the previous 2007 model it has been completely revamped. It is a floorstanding three-way column speaker that is reflex-loaded. There are two 5" long-throw SEAS woofers with polypropylene cones and a 5” SEAS midrange driver with a cone made from double-treated paper. The tweeter, by Scanspeak, is the same as those used on the more expensive Seconda and Quinta models (originally released in 2011).

The Opera Grand Mezza is a comprehensive and versatile speaker system suitable for the most demanding musical programs, but it can also be easily used in sophisticated home theater systems as well.
