GRS NRT25-8 1″ Extended Range Driver 8 Ohm
NRT (Neo-Radial Technology) harnesses the power of radially aligned neodymium magnets to deliver high-fidelity audio through a uniformly magnetic field, ensuring superior speaker sensitivity and acoustic precision
Redefining Audio Performance
The GRS NRT25-8, leveraging Neo-Radial Technology (NRT), delivers expansive, low-distortion sound from a compact 1″ 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 450Hz, offering a versatile spectrum of crossover possibilities for tailor-made audio solutions.
1″ Titanium Diaphragm
Prized 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 Technology
A 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 1″ driver
Extreme Ventilation
By 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 1″ driver that resonates with its depth and clarity. With a frequency sweet spot that extends from 400 Hz to a soaring 20 kHz, experience the brilliance of consistent, high-fidelity audio.
