GRS NRT50-8 2" Extended Range Driver 8 Ohm NRT (Neo-Radial Technology) harnesses the power of radially aligned neodymium magnets to deliver high-fidelity audio through a uniform magnetic field, ensuring superior speaker sensitivity and acoustic precisionRedefining Audio Performance The GRS NRT50-8, leveraging Neo-Radial Technology (NRT), delivers expansive, low-distortion sound from a compact 2" titanium diaphragm. Designed with the DIY enthusiast in mind, this driver features a small footprint perfect for array configurations, a high-force motor for controlled performance, and extensive venting that lowers the frequency range to 200Hz, offering a versatile spectrum of crossover possibilities for tailor-made audio solutions. 2" Titanium DiaphragmPrized for its exceptional stiffness-to-weight ratio; the rigidity of the titanium cone ensures minimal distortion, even at high output levels, while maintaining a clear and detailed sound across a wide frequency range. NRT Neo-Radial TechnologyA breakthrough in speaker design; this innovation results in exceptional linearity and a higher sensitivity in speaker output. The unique configuration allows for an increased excursion capability, providing deep, resonant bass and a broader dynamic range from a 2" driver Extreme VentilationBy allowing air to move freely behind the diaphragm, this ventilation method reduces air pressure build-up that can restrict the cone's movement, especially at lower frequencies. The result is a more natural and extended bass reproduction, Frequency Response Engineered for acoustic excellence, this speaker driver delivers a powerful bass response from a 2" driver that resonates with its depth and clarity. With a frequency sweet spot that extends from 180 Hz to a soaring 15 kHz, experience the brilliance of consistent, high-fidelity audio.Specifications:Impedance: 8 OhmsSize: 2"Cone Material: TitaniumSurround Material: FoamFrequency Range: 180Hz - 15,000HzSensitivity: 79.9dbSPL @ 2.83V/1mPower Handling: 15WXmax: 2.5mm Impedance Curve The driver’s optimized impedance ensures that the speaker operates consistently across a wide spectrum of frequencies, revealing a perfect harmony between power and performance. This simplicity in impedance response translates to a simple crossover configuration with no need to accommodate for losses from electrical interactions.
