Contriva Diacera

From the beginning, the "Diacera" designation has been used for our spectacularly elaborate prime range of speakers, all of which feature the outrageously expensive 30mm diamond tweeter as well as the crossover technology deployed in the Sunray. Trying to describe this speaker's sound is a futile exercise, and it is certainly incorrect to identify the diamond tweeter as the sole reason for its masterful performance. The first few notes of music you will hear will tell more than a thousand words can do

  • adjustable diamond-tweeter curve (hard room-refections / soft room-reflections)
  • serial equipped as SE-version (since June 2010): silver-carbon resistors, ultra grade PIO-Cast copper capacitors, partly silver-wire inside, super low resistance pure air copper inductors
  • extremly linear frequency response, excellent step response, optimised phase and group delay
  • massive silver/goldplated soft-copper binding posts with removeable heads for fullsize-eylets, spades and banana's, wired internally with finest coaxial cable, partly silver cable inside

  • nominal power input: 150 / 300 VA
  • nominal impedance: 4-6 Ohm
  • recommended amp input: We recommend quality instead quantity. Real 20 Watt at 8 Ohm are ok for normal listening levels (in rooms up to 30-60m²). It is most easy to drive and plays even at lowest levels "full and rich". 
    To use the whole enormous dynamic range of it and listening complex music also from time to time very loud we recommend 200 watts at 8 ohm.
  • efficiency: since several unrealistic numbers of competitors we don't want to confuse clients by comparing non-saying numbers on paper. Therefore it is: "Very good efficiency, easy to drive even with tube amps / SET's".
