The copper plating of the top and bottom platesalong with a solid copper phase plug improves theheat conduction and thus contributes to the highpower durability.Gold plated terminals reduce contact resistanceand serves as anti-corrosion.Large windows in the basket both above and belowthe spider reduces sound reflection, air flow noiseand cavity resonances.Woofer driver Also for the bass register we selected a SEAS driverof the type coated paper, a very well-tried type withan unbeatable relation between price/performance.The coated paper cone is extremely light but stillextremely stiff and effectively reduces resonances.The rubber surround makes sure that no edge res-onances are present.The moulded metal basket of "high flow" type thatis acoustically transparent and high precision sincethe basket is shaped exactly due to moulding. Thismakes sure that the basket is very stable and effi-ciently reduces resonances. The basket is absolutelynone magnetically, which contributes to a higherefficiency of the driver.A strong magnet combined with the light coneyields a high efficiency and a good transient re-sponse. Gold plated terminal reduces contact res-istance and serves as anti-corrosion.Large windows in the basket both above and belowthe spider reduces sound reflection, air flow noiseand cavity resonances.Crossover /Binding postFor the midrange and tweeter we have chosen a-12/18 dB crossover that has a fast transient re-sponse and a minimum of phase shiftings.The connectors are gold-plated and of bi-wiringtype so that you can connect to the amplifier withdouble cables (tri-wiring), or connect to two ampli-fiers (tri-amping) for further improving the sound.The following coupling modes are available:1. Upper terminal + mid+ lower terminal(loops present)Default setting, the loudspeaker is fed with the en-tire frequency range.Without the loop between upper and lower termin-al:2. Upper terminal. The signal is only fed to thetweeter.3. Mid terminal. The signal is only fed to themidrange.4. Lower terminal. Now the signal is fed to thewoofer only.Page: 5
