3-1/2 Aluminum Cone Full-Range Neo Driver, 4 Ohm

The Dayton Audio ND91-4 3-1/2" full-range driver boasts impressive low distortion and high excursion capabilities, making it an ideal choice for miniature point-source monitors, surround speakers, and line arrays. When paired with the matching ND series passive radiators, this driver can deliver incredible full-range sound from compact enclosures.

The driver's performance is characterized by low distortion and a full-range response from 65 Hz to 17 kHz. Its cone is made of rubber-edged black anodized aluminum alloy, providing a large excursion capability of 4.6 mm Xmax and a peak displacement of 25 mm.

At the heart of the driver's design is a self-shielded Neo-Balanced motor structure that incorporates a copper alloy shorting ring. This motor structure, combined with the 1" 4-layer underhung voice coil with a polyimide former, ensures efficient and precise control over the driver's movement.

The low distortion and full-range performance of the Dayton Audio ND91-4 make it well-suited for a variety of applications, from miniature point-source monitors to surround speakers and line arrays. When paired with the matching ND series passive radiators, this driver can produce an incredibly full and immersive sound from compact enclosures, providing an excellent solution for space-constrained audio systems.

The driver's rubber-edged, black anodized aluminum alloy cone not only contributes to its large excursion capability but also enhances its durability and resilience. The self-shielded Neo-Balanced motor structure, with its copper alloy shorting ring, helps to minimize distortion and ensure accurate and consistent performance, even at higher volumes.

The 1" 4-layer underhung voice coil with a polyimide former further enhances the driver's control and responsiveness, allowing for precise and detailed sound reproduction. This combination of technical features ensures that the Dayton Audio ND91-4 full-range driver delivers exceptional performance in a wide range of audio applications.

Whether you're looking to build a compact point-source monitor, a surround sound system, or a high-performance line array, the Dayton Audio ND91-4 3-1/2" full-range driver is a compelling choice. Its low distortion, full-range capabilities, and impressive excursion make it a versatile and compelling option for audiophiles and audio professionals alike.
