18 Sound 8NMB750 – High‑Performance 8″ Neodymium Mid‑Bass Driver
The 18 Sound 8NMB750 is a high-output, 8-inch mid-bass driver built for precision, efficiency, and long-term reliability in compact professional audio systems. Made in Italy by 18 Sound, this transducer combines advanced motor engineering, neodymium magnet technology, and robust environmental protection, making it an excellent choice for portable PA systems, stage monitors, and compact two-way speaker designs.
Built for Clarity and Efficiency
At the core of the 8NMB750 is a 3-inch Interleaved Sandwich Voice Coil (ISV) wound on a fiberglass former. This configuration allows for high thermal stability, excellent heat dissipation, and minimized power compression—ensuring clean performance even under extreme conditions. The driver’s 350W AES-rated power handling and 96.5 dB sensitivity allow it to deliver impressive output without requiring oversized amplification.
This efficient design makes the 8NMB750 ideal for applications where power-to-weight ratio and space-saving are key, such as in touring line arrays or active compact enclosures.
Low Distortion, Extended Range
Engineered for accuracy, the 8NMB750 features a frequency response range from 80 Hz to 6 kHz, with a generous ±6.1 mm of linear excursion (Xmax). This makes it an excellent mid-bass driver, offering deep punch and clear definition throughout the vocal and instrument midrange.
To maintain ultra-low distortion, the motor assembly includes a Single Demodulating Ring (SDR) and an additional copper ring—components that linearize the magnetic field and reduce unwanted harmonic and intermodulation distortion. The result is articulate, uncolored sound reproduction, even during demanding live performances.
Tour-Ready Durability
Built to withstand the rigors of live sound, the 8NMB750 incorporates a weather-treated curvilinear paper cone that is both rigid and resistant to moisture. Its top and back plates are coated for added protection against corrosion and environmental wear. Whether used indoors or on the road, this driver delivers consistent performance in all conditions.
The die-cast aluminum basket provides additional mechanical strength and rigidity while keeping overall weight low. With a total weight of approximately 5.2 kg, the 8NMB750 offers an ideal balance of portability and robustness.
Application Versatility
With a nominal impedance of 8 Ohms, a resonance frequency of 88 Hz, and highly controllable Thiele-Small parameters, the 8NMB750 is optimized for both reflex and sealed enclosures. Its flexible design allows it to integrate seamlessly into compact cabinets or multi-driver systems as a dedicated mid-bass unit.
Whether you’re building a tour-ready monitor wedge, a high-performance two-way box, or a compact flown array, the 8NMB750 brings efficiency, punch, and sonic precision to the heart of your design.
