Hand assembled in Brooklyn.\u003c\/h3\u003e\n\u003cp\u003eGrado uses three different wood species for the first time in one headphone. The housing sleeve is made from maple, with a hemp core, and a cocobolo outer ring. For decades, Grado has used wood for its warm and embracing tonal abilities, but finding the right balance of three separate kinds of wood is no simple task. Here, the combination is an ideal complement to the 50 mm X driver, with the maple doing most of the resonance or damping, the hemp smoothing out the top and low ends, and the cocobolo adding that extra punch. Together the sound is full-bodied, dynamic, and truly defined.\u003c\/p\u003e\n\u003ch4\u003eLarge 50 mm X Driver\u003c\/h4\u003e\n\u003cp\u003eThe RS1x is the first headphone to be built with the larger 50mm X drivers, which have been specially tuned for the tri-wood RS1x. The new design features a more powerful magnetic circuit, a voice coil with decreased effective mass, and a reconfigured diaphragm. Reengineering these components for the 50mm drivers improves efficiency, reduces distortion, and preserves the harmonic integrity of your music.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eTransducer Type:\u003c\/strong\u003e Dynamic\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperating Principle:\u003c\/strong\u003e Open Air\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 12 - 30,000 Hz\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSPL (1mW):\u003c\/strong\u003e 99.8 dB\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNominal Impedance:\u003c\/strong\u003e 38 Ohm\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDriver Matching:\u003c\/strong\u003e .05 dB\u003c\/p\u003e","brand":"Grado","offers":[{"title":"Default Title","offer_id":42073291063480,"sku":"G RS-1x","price":750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/products\/grado-rsx1-011-edit-b.jpg?v=1741630357","url":"https:\/\/upscaleaudio.pro\/products\/grado-reference-series-rs1x-headphones","provider":"Upscale Audio","version":"1.0","type":"link"}
