Revel is the brand-name applied to high-end loudspeakers made by the giant conglomerate Harman International (an independently controlled subsidiary of Samsung). I mention this specifically because Harman International is also the parent company behind two of the world’s best-known and highly-regarded hi-fi loudspeaker manufacturers: JBL and Infinity, which not only puts loudspeakers made by Revel on a pedestal, but also means that Revel’s engineers have access to all the same research and development facilities as the engineers at JBL and Infinity, as well as to all the same materials and manufacturing facilities.
EQUIPMENT
When Revel introduced the original Performa series in 1999, it was the first time that the company’s premium metal diaphragm drivers had become available on any loudspeaker other than Revel’s flagship Ultima Series models. Two different alloys were used: aluminium for tweeter domes and aluminium/magnesium for midrange and bass driver cones. The Performa2 Series, introduced in 2003, saw the addition of waveguides to the tweeter diaphragms. The Performa3 Series, of which the M105 is a part, introduced new tweeters and a new generation of wave-guides.
In fact the Performa3 Series was so successful for Revel that it added the Performa-Be Series to its line-up in 2018 as a mid-way point between the Performa3 Series and the Ultima Series. The Performa Be Series saw a switch in the metal from which the tweeters were being made from aluminium to beryllium
