I am selling a clean pair (8/10)of Opera Quinta speakers for a good customer. Reviews were all excellent on the Quinta's. My pair has a 1" scratch on the bottom right side of one speaker with a 1/4 inch mark above it. The other one is a 9/10. The speakers look great. A wood worker could repair the 2 smalls defects for about $200.00 or less. System The Opera Quinta differs from the previous model of the same name by having a new cabinet, new components and new crossover. The cabinet is slightly larger than before, with an internal volume of around 60 litres and is divided into two chambers; the lower chamber, of roughly 40 litres houses two bass drivers. The upper chamber, of roughly 20 litres houses the upper bass driver. The three reflex ports are mounted on the loudspeaker`s rear panel. There are 4 gold plated terminal connectors and the speaker is bi-wirable if required. Cabinet All Linea Classica models have their cabinets in shaped MDF, with sides veneered and lacquered using real wood, while the remaining sides are finished in leather. The size of the front panel, following Opera’s tradition, is large enough to hold the loudspeakers. The inside of the cabinet is divided into two separate chambers, which not only reinforces the structure but also raises the frequency of the first normal resonance mode. The inside of the cabinet is filled with quality acrylic wadding, which helps eliminate internal reflections and resonance and assists bass frequency damping. The bass reflex ports are placed on the rear panel. Components All models of the Linea Classica Series use the same drive units; the one inch tweeter (the same used in the Callas SP) is a silk dome unit, with ferrofluid in the air gap and having a wide rear decompression chamber. The qualities of this SEAS tweeter are well known and appreciated. The woofer, also made by SEAS, was developed specially for this line of loudspeakers. It is a 6.5 inch unit with 18cm chassis, 38mm voice coil, aluminium diaphragm and rubber outer suspension. It has a dynamic mass appreciably higher than the norm, and an impedance of 4 ohm. Two copper rings are fitted above and below the T-shaped pole piece, which both reduce distortion and stabilize the magnetic flux. Finally, the bullet-shaped phase plug in ABS helps to dissipate heat and overcomes compression effects associated with normal dust-caps. It also improves emission at the high-frequency end of the unit`s range. The cast chassis, of aerodynamic design, is fully open even beneath the inner suspension. Crossover In designing the new Classic Series, particular attention has been paid to electrical impedance. This is to ensure that the loudspeaker will present a load compatible with every type of amplifier. The minimum impedance for a nominally 6 Ohm loudspeaker under DIN regulations is not less than 4.8 Ohms at the lowest point of the impedance curve. Opera Quinta adhere to this norm. The electrical impedance curve of the Opera Quinta is in fact always above 5.9 Ohm (5.54 Ohm real impedance at 20KhZ) and although not completely resistive it is extremely regular with phase rotations close to zero over a wide range of frequencies from 200Hz upwards. This ease of drive makes the Opera Quinta a rarer breed, opposed to prevailing tendencies in loudspeaker design. Sensitivity is 89Db (2.83V/1 metre). It should be mentioned that this value is obtained at a high and almost purely resistive impedance. At Opera we believe that the cost of a loudspeaker should be considered together with the cost of a suitable amplifier to drive it; it is of little use to have an attractive price for the loudspeaker if a very expensive amplifier is then required to give good results. The Opera Quinta is a very easy loudspeaker to drive, and best results can be achieved with any type of amplifier whether valve or solid-state. The crossover of the Opera Quinta is a `two-and-a-half-way`, with three bass units connected in quasi-series.
