Optimized for Mid-Bass Clarity and Precision

At the heart of the 6NMB900 lies a 44 mm (1.75‑inch) edge-wound aluminum voice coil, optimized for thermal efficiency and stable performance under load. The neodymium magnet structure ensures high magnetic flux in a lightweight assembly, supporting consistent output without bulk.

Covering a frequency range from 200 Hz to 7 kHz, the 6NMB900 provides robust mid-bass reproduction that’s ideal for vocal and instrument presence, yet it blends smoothly with high-frequency drivers. Its sensitivity of 97.0 dB SPL (1W/1m) allows dynamic, high-output systems with less amplification—ideal for energy-efficient, compact installs.

High Output with Low Distortion

The 6NMB900 is rated for 200 W AES and 260 W continuous program power, delivering confident, long-term performance without strain. A Single Demodulating Ring (SDR) and ventilated motor design reduce distortion and improve transient accuracy—even under peak excursion levels.

Its ±3 mm linear Xmax allows tight control of cone motion, translating into clean, impactful mid-bass output without the muddiness often found in smaller drivers.

Built for Consistency and Durability

The treated paper cone is moisture-resistant and precisely shaped for optimal rigidity and natural damping—ensuring dependable performance whether in a controlled studio or a humidity-prone environment.

Neodymium materials and vented design elements aid thermal management, while the driver’s rugged assembly ensures lasting service in touring, installation, and outdoor settings.

Ideal for Compact High-Output Systems

The 6NMB900 is suited for a wide range of professional applications:

• Line array modules requiring compact mid-bass solutions

• Portable two-way systems where space and weight are limited

• Stage monitors needing powerful yet compact bass outputs

• Custom multi-driver enclosures with tight footprint constraints

Its versatile performance, lightweight build (~1.25 kg), and consistent output make it a go-to choice for demanding sound environments.
