B&C 14CXN88 – Improve Your Coaxial Build with the Perfect Mid-Sized 14″ Driver

Not every build needs a 15-inch driver, and not every 12-inch driver gives you enough low end. The B&C 14CXN88 sits right in that sweet spot — a 13.5-inch coaxial that delivers better bass extension than a 12 and smoother, more balanced midrange than a 15.

If you’ve been going back and forth between driver sizes for your next cabinet, the B&C 14CXN88 gives you a compelling middle ground. You get a full 1000 W continuous power handling, 99 dB sensitivity, and 80-degree coverage from a frame that’s compact enough to fit enclosures where a 15 would be too large.

With an 88 mm voice coil, double silicone spider suspension, and a titanium compression driver — the same high-output architecture found in the 15CXN88 — this driver punches well above its size class. It’s a serious option for builders who want full-range coaxial performance in a more manageable footprint.

Design and Construction of the B&C 14CXN88

The B&C 14CXN88 shares its core motor platform with the larger 15CXN88, which means you’re getting the same 88 mm (3.5-inch) aluminium voice coil and neodymium ring magnet assembly in a smaller frame. The larger coil gives you significantly better thermal handling than standard 76 mm designs, so the driver stays cooler and compresses less during sustained high-power use.

The double silicone spider suspension provides tight mechanical control over the cone’s movement. Combined with 9 mm of linear excursion, your build gets clean, controlled bass output even when you’re pushing the driver hard. You won’t hear the cone losing composure at high volume the way single-spider designs often do.

The glass fibre former gives the voice coil a rigid, thermally stable platform, while the waterproof-treated paper cone protects against moisture damage. If you’re building for outdoor events or humid environments, that WP treatment means you don’t have to worry about your cones deteriorating over time.

An aluminium demodulating ring built into the motor structure suppresses modulation distortion through the midrange. This is especially valuable in a coaxial design where the woofer handles everything from deep bass up to the 1.2 kHz crossover point — you’ll hear cleaner vocals, clearer guitar tones, and more detailed midrange content.

The high-frequency section uses a 75 mm (3-inch) aluminium voice coil with a titanium diaphragm, delivering 106 dB sensitivity. The neodymium motor pushes 1.75 T flux density at the HF gap, giving the compression driver serious magnetic force for crisp, projecting highs that cut through even in loud environments.

The entire assembly runs on a single neodymium ring magnet powering both drivers, keeping the total weight to just 7.4 kg. That’s remarkably light for a 1000 W coaxial, making your finished cabinet easy to carry and simple to rig.

Performance and Applications for the B&C 14CXN88

The B&C 14CXN88 handles 1000 W continuous on the LF section and 160 W on the HF, so you have genuine headroom for demanding applications. The 3.6% reference efficiency means your amplifier watts translate efficiently into SPL — you don’t need a monster amp to get serious volume out of this driver.

The Thiele–Small parameters tell an interesting story about enclosure design. With a Qts of 0.26, an EBP of 170 Hz, and a Vas of just 100 litres, this driver is firmly optimised for compact vented cabinets. That 100-litre Vas is significantly smaller than the 15CXN88’s 124 litres, which means you can build a noticeably smaller enclosure while still achieving proper bass-reflex alignment.

The 20.7 Tm Bl factor — actually higher than the 15CXN88 — confirms that the motor has excellent authority over the cone. You’ll get tight, punchy bass that stays controlled and defined, even at high output levels. This is where the 14-inch format really shines: you get enough cone area for satisfying low-end weight, but with tighter midrange performance than a larger driver would produce.

Builders commonly choose the B&C 14CXN88 for:

• Compact high-power PA tops that need to stay portable
• Coaxial stage monitors with balanced midrange and solid low end
• Two-way full-range cabinets where a 15 is too large and a 12 isn’t enough
• Installed sound in theatres, churches, and conference spaces
• Outdoor and festival builds requiring weather-resistant, lightweight drivers

B&C offers the FBCXN88 passive crossover network, designed to work with the entire CXN88 family. If you want a simple passive build without designing your own filter or running DSP, the FBCXN88 gives you a matched crossover solution straight out of the box.

Both the woofer and compression driver share the same acoustic centre, delivering true point-source output at every listening position. No comb-filtering, no off-axis lobing — just coherent, phase-aligned sound that makes your cabinet perform exactly the way you designed it.

Conclusion

The B&C 14CXN88 is the ideal choice for builders who want the output and power handling of the CXN88 platform in a more compact package. Its 13.5-inch frame gives you better bass weight than a 12-inch driver while delivering cleaner, more focused midrange than a 15-inch alternative.

The 88 mm voice coil, double spider suspension, and 9 mm linear excursion handle 1000 W without flinching, and the titanium HF compression driver projects crisp highs at 106 dB sensitivity. With a tiny 100-litre Vas that suits genuinely compact enclosures and the matched FBCXN88 crossover for easy passive builds, the B&C 14CXN88 is a smart pick for any builder looking for the perfect balance between size, output, and midrange clarity.
