Grado Reference Series RS2i Headphones
Although a miniature version of the RS1i, the RS2i still maintains an overall sound that is pure Grado.
The RS2i is the little brother of the RS1i and shares all of the characteristics of its distinguished elder sibling. It also boasts upgraded drivers, the new 8 conductor cable design and a handcrafted wooden air chamber. However, although the carved mahogany enclosure of the RS2i is smaller than that of the RS1i, it still produces a sound that is pure Grado; full bodied vocals, excellent dynamics and an ultra smooth top end.
The Frequency response is 14Hz - 28kHz. The drivers are matched to 0.05dB.
The handcrafted mahogany earpieces are made using an intricate curing process. The result is superb tonal quality, free from unwanted resonance.
Grado Headphones, Better By Design
All Grado headphones have a vented diaphragm design that incorporates a large air chamber. This design concept lowers the frequency resonance (distortion) of the diaphragm and extends bass response. The diaphragm is made of a low mass polymer, carefully formed to broaden resonant modes to reduce their amplitude. The diaphragm mass is determined with the compliance of the suspension in mind so that the desired low frequency resonance is achieved.
The Professional, Statement, Reference Series, and along with the Prestige Series (SR325is, SR225i and SR125i), feature voice-coils that are wound from ultra-high purity, long crystal (UHPLC) oxygen-free copper. The copper is slowly drawn through the die in extremely small increments and is annealed following each drawing operation. Ultra-high conductivity copper yields the clearest transmission and lowest colouration possible. The sound of UHPLC copper is smoother, cleaner and more dynamic. All use very high power neodymium magnets to provide maximum efficiency and better sound. Each headphone driver is made to Grado's high standards, then pair-matched for exact imaging. These headphones also utilise UHPLC copper in the connecting cable.
Technical refinements for Grado drivers include improved diaphragm and voice coil design for increased bass response and a larger perceived sound stage. A unique process to "de-stress" the diaphragm results in enhanced inner detail. An increased ability to control driver resonance virtually eliminates distortion. For all models, an improved headband spring will afford greater comfort for the majority of listeners.
The Grado Sound
Grado headphones can reproduce as natural a soundstage from stereo recordings and provide as much listening pleasure as a good pair of speakers do. Grado headphones are free of room effects and placement problems, and they minimise any interference from external noise. They also offer portability and the ability to listen without worrying about the neighbours. With Grado headphones, you will hear recordings with greater clarity and with deeper bass than others. Grado headphones are the antithesis of mass production, as each Grado headphone is hand-assembled and closely scrutinised to meet full performance specifications in the U.S.A.
The Grado story started in 1953 with the production of high-end phono cartridges.
The Grado Story
Grado is one of the oldest family owned companies in the audio industry. For more than half a century it has been a leader in design engineering for the high-end audio and recording industries.
Grado is famous for their remarkable headphone and phono cartridge designs and hold over 48 patents. Company founder, Joseph Grado is credited as the inventor of the stereo moving coil phono cartridge. He is responsible for more innovations in phono cartridge design than any other person in our lifetime and was inducted into the Audio Hall of Fame in 1982.
The Legacy Continues...
Joseph Grado has passed on the mantle of President to his nephew John Grado. John has risen from sweeping the floors of the factory as a twelve year old, to President and Owner of Grado Laboratories. Following on from Joseph Grado's acclaimed designs, John has led the development of the Prestige, Reference and Statement Series of headphones and phono cartridges and the Professional Series of headphones. All of which have received world wide acclaim by the audio press.
