Rega’s new flagship speakers, the RS-10, were designed to complement Rega’s top-end Isis CD player and Osiris amplifier.
It is a flexible speaker that will fit into any system and any room since it has an “environment match” adjustment feature.
Like the other floorstanders in the range, the RS-10 is slim with a small footprint and the woofers are side-firing. It features a quarter wave transmission line design.
The RS-10 uses a BMR (Balance Mode Radiator) to handle the majority of the audible music spectrum.
According to Rega’s literature, the “BMR design concept was conceived as a full range driver handling all musical frequencies from bass through to treble with a single driver and no crossover.
“This concept works remarkably well and produces a musical transparency normally associated with electrostatic loudspeakers.
However no concept is perfect and a single BMR can only produce limited bass output and some people may prefer more precise musical images.
“Most loudspeaker systems have a crossover point for the mid range driver and tweeter between 2 KHz and 3 KHz. This can upset the vocal region with distortion and phase shift. It is also where the human ear is most sensitive.
“Therefore with use of the BMR unit, Rega has been able to design a crossover point above the most critical range. The high frequency capability of the BMR, has allowed the two units to integrate to 6 KHz. This gives massive improvements in sound quality with greater clarity and detail in the music. Rega has pioneered the integration of a BMR with the unique Rega dual driver bass system and a completely new and unique Rega designed and UK manufactured tweeter.”
Rega designed a unique tweeter that would complement the BMR unit. This new tweeter the ZRR-10 uses Rega’s ZRR (Zero Rear Reflection) technology combined with an unparalleled production technique that allows the silk dome to be assembled directly onto the front plate thus eliminating a major source of unwanted vibration. Each tweeter incorporates a copper Faraday ring which extends the frequency response of the tweeter up to 23Khz by lowering inductance of the voice coil.
For bass frequencies the RS-10 uses two separate bass drivers connected in parallel. The drivers are different sizes, have different resonant frequencies and operate with individually separate cabinet loading: A 200mm driver with a lightweight paper cone, 8 layer voice coil and a resonant frequency of 40Hz operates in a transmission line with port output extending below audibility coupled with a 125mm driver also with a lightweight paper cone, 8 layer voice coil and resonant frequency of 75Hz which is loaded by a small sealed cabinet.
This system eliminates the normal single bass resonance by spreading smaller resonances across the entire bass frequency band and incorporates a degree of self damping due to the parallel connection with the amplifier.
