The RS-10 speakers use a Balance Mode Radiator (BMR) system to handle most of the audible music spectrum. The BMR concept was envisioned as a full-range driver that handled all musical frequencies from bass to treble with a single driver and no crossover. This concept works very well and produces a musical transparency usually associated with electrostatic speakers. But no concept is perfect and a single BMR can produce only limited bass output and some may wish for a more precise musical imaging. Most speakers have a crossover point for the midrange driver and tweeter between 2KHz and 3KHz.
This can disturb the vocal range with distortions and phase shifts. And it is also the area where the human ear is most sensitive. So with the use of the BMR, Rega has managed to create a crossover point above the most critical area. The capability of the BMR on the high frequencies has allowed to integrate the two drivers at 6 KHz. This allows for a dramatic improvement in sound quality with greater clarity and musical detail. Rega has chosen to integrate the BMR technology loudspeaker with the unique Rega dual driver bass system and a brand new and exclusive Rega tweeter.
BMR's high-frequency sound is so good that the quality level of a normal tweeter would not have matched. This is why Rega felt compelled to design a brand new tweeter to match the BMR. This new tweeter, ZRR-10, uses Rega ZRR (Zero Rear Reflection) technology combined with an unrivaled manufacturing technique which allows the silk dome to be assembled directly onto the front end eliminating a significant source of unwanted vibration. Each tweeter is meticulously hand assembled in Rega and incorporates a copper Faraday ring which extends the frequency response of the tweeter up to 23KHz by reducing voice coil inductance.

For low frequencies, the RS-10 loudspeakers use two separate drivers wired in parallel. The drivers are of different sizes, have different resonant frequencies and operate with separate cabinet loads. A 200mm driver with a lightweight paper cone, an 8-layer voice coil and a resonant frequency of 40Hz operates in a transmission line with an output extending below the audible level and is coupled to a 125mm driver also with a light paper cone, an 8-layer voice coil and a resonant frequency of 75Hz loaded from a small closed cabinet.
This system eliminates the resonance of the normal single bass by spreading smaller resonances across the entire bass frequency and incorporates a degree of self-damping due to parallel connection with the amplifier.
The result is a fuller, more precise bass register whose level can be adjusted to match the characteristics of the room. The speaker can also be positioned closer or further away from a wall generating a boost or cut of low frequencies to suit personal taste.

The EMS (Environment Match Settings) system allows the user to adjust the speakers to match the room. Changing these settings changes the balance between low and high frequencies. By simply adjusting the positions between the three presets available on the rear of the speaker it offers maximum flexibility in even the most difficult rooms.
