DESIGN AND INNOVATION

SKELETAL PLINTH DESIGN WITH POLYOLEFIN FOAM CORE

Controversially, Rega has always researched methods of producing light but stiff and

rigid plinths. The technology is simple: unwanted noise at microscopic levels is

developed by the turntable motor and main bearing. The plinth can also pick up airborne

vibration from the music. From it’s beginning in the 1970’s, Rega pioneered the use of a

stressed skin structure for the plinth. This uses two layers of phenolic resin with a

lightweight particle or fibre board sandwiched between the skins. This technique has

been used in many applications where stiff, light structures are needed, such as an

aircraft wing or a Formula 1 chassis.

The current revival in turntables has allowed Rega to research and develop higher

technology structures for the customer who is happy to pay a little more for higher

sound quality. The RP8 & RP10 turntables utilise a unique stressed skin structure

produced from thin phenolic skins sandwiching a featherweight, nitrogen expanded,

closed cell, polyolefin foam core. This material has been developed exclusively for Rega

over a three year period. The RP10 plinth is seven times lighter than the weight of the

original Planar 3 plinth. In addition Rega has added even more stiffness in the crucial

area between the arm and the main bearing.
