&C 14CXN76 – Improve Your Build with a Lightweight 14″ Neodymium Coaxial

Looking for a mid-sized coaxial that gives you full-range point-source performance without weighing down your cabinet? The B&C 14CXN76 delivers exactly that — a 13.5-inch neodymium coaxial with 100 dB sensitivity, 800 W continuous power, and a total weight of just 5.6 kg.

That makes the B&C 14CXN76 one of the lightest high-output coaxials in its size class. For builders who want the balanced midrange and manageable cabinet dimensions of a 14-inch driver without sacrificing output or efficiency, this is a driver that earns its place on the shortlist.

With 80-degree coverage, a polyester/titanium HF diaphragm, and a copper voice coil that offers superior thermal conductivity, the B&C 14CXN76 is built to perform reliably across everything from compact PA tops to coaxial wedge monitors and permanent installations.

Design and Construction of the B&C 14CXN76

The low-frequency section of the B&C 14CXN76 uses a 76 mm (3-inch) copper voice coil wound on a glass fibre former. Copper winding is a meaningful advantage here — it provides better thermal conductivity than aluminium, which means the coil dissipates heat more efficiently during sustained high-power use.

For your build, that translates to less power compression and more consistent output over long sets or events. The driver keeps delivering the same SPL at the end of a four-hour gig as it did at the start, which is something you’ll genuinely notice compared to aluminium-wound alternatives.

The moving mass is impressively low at just 67 g — lighter than both the 14CXN88 and the 15-inch CXN models. That low mass gives the B&C 14CXN76 fast, responsive transient behaviour. You’ll hear the difference in the snap of a snare drum, the attack of a kick, and the crispness of vocal consonants.

The waterproof-treated paper cone handles moisture without degrading, so outdoor builds and humid venue installs are no problem. An aluminium demodulating ring built into the motor structure keeps distortion low across the midrange — essential in a coaxial where the woofer covers everything from deep bass up to the 1.2 kHz crossover point.

The high-frequency section features a 75 mm (3-inch) aluminium voice coil paired with a polyester/titanium composite diaphragm. This hybrid material is a real benefit for your build — titanium provides the stiffness for extended high-frequency reach, while the polyester layer adds internal damping that reduces breakup harshness.

The result is smooth, detailed highs at 105 dB sensitivity without the brittle edge that pure titanium diaphragms can sometimes produce at high volume. The neodymium motor drives 1.8 T flux density at the HF gap, giving the compression driver plenty of magnetic force for crisp projection across your listening area.

Performance and Applications for the B&C 14CXN76

The B&C 14CXN76 handles 800 W continuous on the LF section and 160 W on the HF, giving you solid headroom for professional applications. With 4% reference efficiency — the same as the larger 14CXN88 — your amplifier watts convert efficiently into SPL. You don’t need a massive power amp to get this driver working hard.

The Thiele–Small parameters point clearly toward vented enclosure designs. A Qts of 0.28 and EBP of 155 Hz confirm that the 14CXN76 is optimised for bass-reflex cabinets. The 131-litre Vas gives you flexibility in tuning, and the 8 mm linear excursion ensures clean bass output without the cone running out of travel.

The 18.4 Tm Bl factor gives the motor strong authority over the cone, delivering tight, defined low end that doesn’t get muddy under load. Paired with the driver’s low 67 g moving mass, you get a combination that’s fast, efficient, and punchy — exactly what you want in a compact full-range cabinet.

Builders commonly choose the B&C 14CXN76 for:

• Ultra-lightweight portable PA tops and powered speakers
• Coaxial wedge monitors with natural, balanced midrange
• Compact two-way full-range cabinets for gigging and events
• Installed sound in churches, theatres, and conference rooms
• Outdoor and festival builds requiring weather-resistant drivers

Because both drivers share the same acoustic centre, your cabinet produces true point-source output with coherent phase alignment at every seat. No comb-filtering, no off-axis lobing — just predictable, even sound that makes your enclosure design work the way you intended.

Conclusion

The B&C 14CXN76 is the coaxial to choose when weight and speed matter as much as output. At just 5.6 kg with a 67 g moving mass, it’s one of the lightest and fastest 14-inch coaxials available — and it still delivers 100 dB sensitivity and 800 W continuous power handling.

The copper voice coil provides superior thermal performance over aluminium alternatives, the polyester/titanium HF diaphragm gives you smooth highs without harshness, and the aluminium demodulating ring keeps your midrange clean and detailed. Whether you’re building a lightweight gigging cab, a coaxial wedge monitor, or a compact install speaker, the B&C 14CXN76 rewards you with fast, efficient, full-range performance that punches well above its weight.
