About Our Products
After many years of research and development R2R Audio introduced the flagship product – 15 inch Full Range loudspeaker active system.*
This world`s most technologically advanced speaker system sets new standards in frequency response, phase response and impulse response. Now for the first time it's possible to have exceedingly low distortion, wide dynamics, and high sensitivity. This novel system reproduces the unbiased sound with revolutionary accuracy, balance and dynamic power.
Our success is the result of long years of research and trials to find a consistent pattern in development and construction of high-definition audio loudspeakers.
For cone and dome membrane production we use non-woven high modulus polyaramid materials treated with liquid Kevlar™ and Nanoparticles Fullerene C60. This unique production technology allows us to achieve the velocity of sound in moving elements of the drivers up to 12 km/sec. The maximum velocity of sound in moving elements made of traditional materials cannot exceed 3 km/sec.
This ground breaking technology resulted in the reduction of the moving parts' weight, which in our high-effeciency speakers is at least three times smaller then the weight of any other existing speakers. However the mechanical and analog-electrical characteristics of R2R Audio loudspeaker far exceed the quality of competitors. For instance: the slew rate of our 15 inch Full Range driver is 84 Pa/mSec whereas with conventional mid-bass hi-fi and class Pro loudspeakers this parameter is lower than 20 Pa/mSec.
Our technology allows us to produce cones and dome membranes with diameters from 2 to 18 inches with durability of 10 to 15 years in any challenging environment without loosing their original characteristics. Few years ago we designed our first 8 inch Full Range underwater transducer.
Particular attention has been paid to the magnet assembly construction and materials. For their production we use only pure iron Armco and high quality constant neodymium magnets made of NdFeB metal. This gives us a significant magnetic field strength in the gap up to 2,2 T.
One of the most important elements of the technical design are the voice coils. To this end, edge-wound voice coils were developed and are used for our driver production.
Special surrounds and spiders have very low losses from friction with QMS higher than 20.
What makes the R2R Audio Full Range system so completely different from all other current acoustic systems today?
- A single Full Range driver per channel covering the entire audio band
- Impulse characteristics equaling that of electro-static speakers
- The dynamics of electro-static loudspeakers yet a greater than 10 times efficiency than electro-statics
- A velocity of sound as high as 12 km/sec in the drivers moving elements
- No hot spots or localization of the sound source
- A single channel transducer enables a true three dimensional presentation for all types of music programs
- A true representation of the recording source
All R2R Audio active systems use:
- An open baffle design
- Universal class D amplifiers with up to 700 Watts of power
- Linear power supplies with surplus power reserve and special Low ESR sound electrolytic capacitors to avoid power drawdown on low frequencies
- A digital processor for frequency control, no passive elements
- Four user selectable presets for different environments
- A DSP compensation for complete flat frequency response (similar to the principal of phono cartridge frequency correction for vinyl records to achieve full range playback)
Our innovative Full Range loudspeaker systems are used as Home Audio Systems, in Home Theaters, in Sound Recording Studios, for Active Acoustic Environment Enhancement in locations such as concert halls, theaters, cinemas, open air, and under water environments.
All R2R Audio speakers, amplifiers and systems are handcrafted and offered in different custom materials and finishes.
Also, using our own speakers, amplifiers, and unique technology we can design and produce a high quality audio reproduction system customized to your needs. Send us your request, and we will be happy to provide you with solution in accordance with your requirements.
