The Lotus Group's Granada speaker ($125,000/pair) combines 21st-century technologya digital-domain crossover realized with DSP, including room correctionwith distinctively retro loudspeaker engineeringfrequencies above 200Hz are handled by a single Feastrex unit featuring a field-coil magnet and a paper diaphragm with a coincident "whizzer" cone. The paper used for the diaphragms is sourced from a Japanese "National Treasure" paper maker, Ichibei Iwano, and the surrounds are made from lambs' skin. Two woofer handle the bass and all three drivers are open at the back to give a dipole radiation pattern. There is also a rear-firing 0.75" dome tweeter to maintain the speaker's power response in the top octave. (The treble energy from the whizzer is emitted in a quite narrow frontal beam.)
My photo doesn't do justice to the beauty of this speaker; the rest of the system included Musical Fidelity AMS-50 class-A amplifiers, a Steve McCormack VRE-18 preamp, a Hanss T-10A turntable with phono stage and fitted with Dynavector DRT XV-1t cartridge,with interconnects and power cabling by Pranawire and speaker cabling by Acoustic Revive. Total system costs was $324,245! Listening to Joan Armatrading's "Show Some Emotion" then the Roy DuNann-recorded The Eleven LP by Art Pepper, I was struck by the effortless nature of the sound and the sheer musicality of the system, though I have to admit that instruments didn't quite sound tonally correct.
