B&C 10CXN64 – Improve Your 10″ Coaxial Build with High-Output Neodymium Performance

If the 10CLX64 is B&C’s budget-friendly 10-inch coaxial, the B&C 10CXN64 is its high-performance counterpart. This driver takes the same compact 10-inch format and upgrades the motor for significantly more output — 97 dB sensitivity, a stronger 15.8 Tm Bl factor, higher flux density, and a titanium compression driver that handles 160 W continuous.

The B&C 10CXN64 is built for applications where you need a small coaxial to play louder, project further, and maintain fidelity at high SPL. At 3.95 kg and just 142 mm deep, it’s still compact and light enough for portable builds and tight installations — but the upgraded motor gives you performance that punches well into 12-inch territory.

With 70-degree coverage, 500 W continuous power handling, and a matched FB10CX64 passive crossover available, the B&C 10CXN64 gives serious builders a 10-inch coaxial platform that doesn’t ask you to compromise on output or quality.

Design and Construction of the B&C 10CXN64

The low-frequency section of the B&C 10CXN64 uses a 64 mm (2.5-inch) copper voice coil on a Kapton former. Where this driver separates itself from the CLX64 is in the motor — the neodymium magnet assembly is significantly larger, pushing flux density to 1.1 T at the LF gap compared to the CLX64’s 0.9 T. That extra magnetic force is what drives the 3 dB sensitivity advantage.

For your build, 3 dB is a meaningful difference — it’s the equivalent of doubling your amplifier power. A cabinet built around the B&C 10CXN64 will be noticeably louder than one using the CLX64 with the same amp, which matters enormously in live sound and high-output applications.

The moving mass is an ultra-low 33.5 g — the lightest in B&C’s entire coaxial range. That featherweight cone gives the 10CXN64 exceptional transient speed. Kick drums snap, vocals cut through a mix with clarity, and percussion has the kind of immediate attack that heavier drivers can’t reproduce.

The 15.8 Tm Bl factor is remarkably high for a 10-inch driver — it’s actually stronger than the Bl on several of B&C’s 12-inch models. That motor authority keeps the ultra-light cone under tight control, delivering punchy, defined bass that doesn’t get loose even when you’re pushing the driver to its limits.

The waterproof-treated cone and aluminium demodulating ring are carried over from the rest of the CXN range, giving you the same moisture protection and low-distortion midrange that builders expect from B&C’s professional coaxials.

The high-frequency section is where the B&C 10CXN64 really distinguishes itself. A 65 mm (2.5-inch) CCAW voice coil drives a pure titanium diaphragm at 103 dB sensitivity with 1.75 T flux density — significantly more magnetic force than the CLX64’s polymer HF driver. Titanium gives you the stiffness for crisp, detailed highs with excellent projection, while the CCAW winding keeps the HF moving mass low for fast transient response. The 160 W continuous HF handling is also higher than the CLX64’s 140 W, giving you extra headroom in the high frequencies.

Performance and Applications for the B&C 10CXN64

The B&C 10CXN64 handles 500 W continuous on the LF section and 160 W on the HF — the same LF rating as the CLX64 but with much higher efficiency. The 2.2% reference efficiency is double the CLX64’s 1.1%, which means you’re getting twice the acoustic output per watt from your amplifier. That’s a transformative difference in real-world use.

The Thiele–Small parameters point firmly toward vented enclosure designs. A Qts of 0.31 and EBP of 206 Hz confirm the 10CXN64 is optimised for bass-reflex cabinets. The 23-litre Vas keeps enclosure size small, and B&C’s own documentation suggests a 21-litre reflex cabinet tuned to 70 Hz as a starting point for your design.

The 5 mm Xvar provides clean linear excursion for the driver’s size class. Combined with the 15.8 Tm Bl factor and 33.5 g moving mass, you get bass that’s tight, fast, and well-controlled — exactly what a compact high-output cabinet needs to sound its best.

Builders commonly choose the B&C 10CXN64 for:

• High-output compact satellite speakers in sub-sat PA rigs
• Small-format coaxial stage monitors for loud stages
• Column array and line source elements where output-per-driver matters
• Compact installed speakers in bars, clubs, and live music venues
• Nearfield reference monitors where detail and projection are critical

B&C offers the FB10CX64 passive crossover network, purpose-matched to this driver. If you want a clean passive build without DSP or custom filter design, the FB10CX64 gives you a factory-tuned crossover that takes the guesswork out of your two-way system.

Both drivers share the same acoustic centre for true point-source output. The 70-degree dispersion provides natural, even coverage that works well for both nearfield and medium-throw applications, with consistent tonal character on and off axis.

Conclusion

The B&C 10CXN64 is the high-performance 10-inch coaxial for builders who refuse to accept that compact means quiet. With 97 dB sensitivity, a 15.8 Tm Bl factor that rivals many 12-inch drivers, and the lightest moving mass in the range at 33.5 g, this driver delivers output and speed that its size doesn’t suggest.

The titanium compression driver with CCAW voice coil gives you crisp, projecting highs at 103 dB, the upgraded neodymium motor provides double the efficiency of the CLX64, and the matched FB10CX64 crossover makes passive builds straightforward. Whether you’re designing a high-output satellite speaker, a compact stage monitor, or a column array element that needs to hold its own at serious volume, the B&C 10CXN64 gives you professional coaxial performance from a 10-inch driver that genuinely overdelivers.
