Opera Seconda SE Mahogany

Opera Seconda SE Mahogany - 2.5-way floorstanding loudspeaker

Driver
The new 7” woofer is a custom model, made by Scanspeak, for the whole new Classica series. This woofer has an excellent performance in the mid frequencies. It is equipped with an aluminum diaphragm, a 38mm coil (two-layer, CCWA wire) with aluminium former immersed in a suitably shaped air gap. There is also a metal ring around the pole piece to control the flux variations. The basket is die-cast for maximum stiffness. Compared to its predecessor the volume displacement is increased by a 25%. The rigid aluminium diaphragm is free from subharmonics and from transverse modes and perfectly reproduces the lower frequencies.
The tweeter, a D26 series made by Scanspeak, has a one inch high quality treated soft dome, double magnet, decompression chamber, ferrofluid, aluminum flange and a one mm. peak to peak linear excursion (the double of a conventional tweeter).
Crossover
The crossover circuit, two ways and a half, is divided into two different boards placed at suitable distance from each other, to reduce the effects of mutual inductance of coils. The tweeter high-pass sections is designed to minimize the microphonic effect.
Cabinet
The cabinet re-proposes, in the upper part, the curvature of the Malibran model. The front panel, MDF (30 mm thick) is wide enough to accommodate the loudspeakers, has rounded edges and is covered in leather that also acts as a seal for the speaker. The sides of the cabinet are veneered with real wood and finely polished. As a consequence Consistency and Clarity are the hallmarks of the sound of this speaker.
The four externel connectors are the gold-plated brass connectors. They accept any kind of termination providing a safe and effective electrical and mechanical contact.
The insensitivity of the closed box system to sub-sonic frequencies makes our diffusers specially suited to the reproduction of analog records (LPs). The Opera Seconda is also suited to be used as front and/or rear channel in home theater systems: with two pairs of Opera Seconda you can get an Home Theater System that requires no center channel and no sub-woofer.
Particular attention has been paid to the electrical impedance curve to get a diffuser less sensitive to the quality of the cables and amplifier (tube or solid state). Opera Seconda is a true 4 ohm nominal impedance system that meets the DIN 45500 standards that can be driven by any amplifier suited for 4 ohm nominal load.
