Grado Labs

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 diaphragm's total mass is calculated to provide a full 20 KHZ bandwidth, while avoiding break-up at lower frequencies.

RS1 - Featuring handcrafted Mahongany earpieces made using an intricate curing process, Grado has been able to optimize the tonal quality. T he RS1 uses dynamic transducers in an open-air configuration, the cups being open-backed. The result is a smooth, coherent sound with detailed dynamics. Frequency response ranges from 12-30 kHz and the drivers are matched to 0.05dB. Weighing 9oz, the headphones are an example of the wonder of mother nature with a gorgeous, honey-colored look.

 

RS-2 - The newest edition to the Grado family, the RS2 is the little brother of the RS1 . The characteristics of the RS2 remain the same as it's distinguished big brother, with the hand crafted mahogany, but there is a smaller wooden air chamber. Although a miniature version of the RS1, they still maintain an overal sound that is pure Grado, w arm harmonic color, full bodied vocals, excellent dynamics and ultra smooth top end. These truly are audiophiles dream.

 

SR 325i - What does the i stand for in the new SR325 i from Grado? Improved, that's what! Yes, Grado has taken one of the world's most acclaimed headphones and taken it a few steps further. The new SR325 i has an upgraded driver design, and they have enlarged and improved the mass distribution in the metal housing. The way the SR325 i' s new driver and metal housing move air and react to sound vibrations are now less affected by transient distortions. With the SR325 i you will notice improved control of the upper and lower range of the frequency spectrum with both better supporting Grado's world renowned midrange. And why the Gold color? The new SR325 i is in honor of their 50th anniversary celebrated recently. The SR325 i will produce a sound that is pure Grado, warm harmonic color, rich full bodied vocals, excellent dynamics and an ultra smooth top end. Listen and Enjoy!

 

SR 225 - Features are the same as the SR125 but, this Headphone has an increased air flow by 50% which is achieved through an improved rear metal screen and closer matched drivers. The result is an enlarged soundstage achieved from closer driver tolerances, while the improved rear screen frees the headphone from colorations.

SR 125 - Grado's ability to combine lightness with extreme rigidity and internal damping has been put to good use on the SR125. Based on the same design as the SR80 , the SR125 features an improved diaphragm and voice coil design and UHPLC (Ultra-high purity, long crystal) copper voice coil wire. The Diaphragms are put through a special 'de-stressing' process in order to enhance inner detail. An improved headband spring provides even greater comfort allowing the listener to relax and enjoy the fine tonal spread and balance. Bass, midrange and treble are all more open.

 

SR 80 - Built on the same features as the SR60 , but utilizes a 4 conductor connecting cable and larger ear cushions, the result of which gives a more open stage. The SR80 provides an improved bass resonance, which enhances the overall detail. John Grado says he strove for the best sounding phones for the money, and with the glowing reviews the SR80's have received, who can argue.

 

SR 60 - "The most varied group to be voted on, there was very little spread in the balloting with one exception: Grado's remarkable SR60 headphones. Both Corey Grrenberg and Sam Tellig raved about the SR60s in print. Pretty much every other writer who tried them voted for them."
Stereophile / John Atkinson Vol.17, No.12
