The new 7” woofer is a custom model, made by Scanspeak, for the new Classica series. This woofer has an excellent performance in the mid frequencies and is used as a midrange in the Quinta model. It is equipped with an aluminum diaphragm, a 38 mm coil (two-layer, CCWA wire) with aluminium former with 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 significant 25%. The rigid aluminium diaphragm is free from subharmonics and from transverse modes and perfectly reproduces the lower frequencies. The two woofers, connected in parallel, share the same 40 liters enclosed volume.
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 (double of a conventional tweeter). The frequency response extends to 30kHz (0 dB) and 40 kHz are reproduced 6 dB down. The resonant frequency is about 860 Hz which makes this tweeter insensitive to vibrations from other loudspeakers
The tweeter high-pass section is designed to minimize microphonic effects (something rarely done). The capacitors used in the signal path have been carefully selected. This also contributes to the stable and precise soundstage.
The Opera Seconda is suited to be used as front and/or rear channel in home theater systems: with two pairs of Opera Seconda you can get a 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 speaker 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 (minimum impedance greater than 3.2 ohms) that can be driven by any amplifier suited for 4 ohm nominal load.
Available in Black Ash, Mahogany & Cherry Finishes.
