Royd Revelation Range

The aim of hi-fi is to reproduce sound as accurately as possible. This means that it must reproduce the correct musical note, at the correct time, for the correct length of time, and as near as is practical at the correct volume. Of course, "correct" means that sound which was on the original recording.

In order to do this, loudspeakers must be critically damped at all frequencies, and have the least possible phase distortion. Phase distortion is a time delay dependent on frequency: the lower the note or frequency, the longer the time delay for the same phase shift.

The Royd Revelation Range is a considerable step forward, compared with any other type of design.

The use of compound reflex bass loading in these loudspeakers reduces the phase shift compared with standard reflex bass loading by more than 75%, and is 3 times less than a closed box or acoustic suspension type cabinet. A transmission line cabinet has more bass distortion than a closed box, because it adds a further 180 phase shift to that produced by a closed box. Compound reflex bass loading also ensures that all bass frequencies are critically damped and that the Revelation range of loudspeakers reproduce frequencies down to 20Hz in the listening room.

The Royd Revelation Range employs first order crossovers. This type of crossover produces the least possible phase distortion, and introduces no other distortions or resonances.

All models perform at their best with high quality amplification.

Brief History of Significant Royd Models

  • Royd Loudspeaker Co. Ltd.was set up by Joe Akroyd in 1980. His aim to concentrate on designing and manufacturing hifi loudspeakers for those customers around the world where sound quality is of primary concern.
  • The rear ported A7 was introduced in 1982 and the more sophisticated Coniston series in 1984.
  • By 1987 serious development work produced the EDEN, the first mass damped model. This family of stand mounted rear ported speakers continued to be the mainstay of sales until 1990.
  • 1989 saw the introduction of the APEX, a transmission line design and our first floorstanding model.
  • 1990 was celebrated by the launch of the SAPPHIRE and SINTRA , both stand mounted models which largely replaced the Coniston R and EDEN and demonstrated that improvement could be made to established good designs.
  • 1992 saw the ABBOT successfully replace the APEX in all markets.
  • July 1993 saw the launch of the MINSTREL a landmark loudspeaker (as the A7 had been 11 years before). This small floorstanding model was an instant success.
  • The next new model was the SORCERER, a very musical high quality stand mounted loudspeaker, (a limited number of Special Edition Sorcerers in Walnut veneer cabinets is still being produced).
  • In 1995 the DOUBLET, big brother to the Minstrel, a three way model, capable of producing more volume made record sales.
  • 1996 saw the introduction of the ALBION with its improved performance, individual design and matching hardwood stand. This was a particularly popular design in our overseas markets.
  • Joe Akroyd has never set out to simply upgrade any one model. Unless he could justify a positive improvement in performance he continued to stay with his current models. This was why there were no appreciable changes until the new ROYD REVELATION RANGE was introduced in 2001.
