AURUM ALTAN QUADRAL VIII SPEAKER RIBBON LOUDSPEAKERS MINT RRP £1300. IN ORIGINAL PACKAGING 38-65,000 Hz UK ONLY SALE https://www.techradar.com/reviews/audio-visual/hi-fi-and-audio/hi-fi-and-av-speakers/quadral-aurum-altan-viii-989082/review Very high end Ribbon Speakers The drive units are Quadral's own developments, with a 170mm main bass/mid driver that uses an alloy of aluminium, titanium and magnesium (known as Altima) for its 115mm cone. Claimed to be both stiff and light, it's driven from a powerful motor. The VIII in the name refers to the eighth generation of Quadral's ribbon-type tweeter. Indeed, few companies have done more to proselytise an 'alternative' approach to tweeters then Quadral. One consequence of the diaphragm shape is a tendency to beam the highest frequencies in the vertical plane. Reducing any ceiling reflections should help focus the stereo image at some expense in terms of airiness. Twin high-quality multi-way terminals are fixed directly through an alloy plate, using wire for the optional links. Internal wiring from French operation Real Cable uses bi-metal (BM-series) audiophile cable, combining copper (for bass) and silver for treble. The network proper uses metal-layer resistors and high-quality polypropylene film capacitors.
