B&C 15NW100 – Ultimate 15-Inch Neodymium Subwoofer Driver for Maximum Power and Output
The B&C 15NW100 is the most powerful neodymium 15-inch subwoofer driver B&C makes. With a 1000 W AES power rating, 2000 W continuous program power, a 28 Tm force factor, and 97 dB sensitivity, the B&C 15NW100 delivers the highest combination of power handling and output of any neo 15 in the range. Where the NA100 is classified as a woofer with an exponential cone optimised for bandwidth, the B&C 15NW100 is classified as a subwoofer — radial cone, 35 Hz lower limit, 33 Hz Fs, and a 40 Hz tuning recommendation that confirms its role as a dedicated low-frequency powerhouse.
The 28 Tm force factor is the highest of any 15-inch driver in B&C’s entire range — neo or ferrite. That massive motor authority driving a 173 g moving mass gives the B&C 15NW100 the control and transient response to deliver tight, punchy bass even at the high power levels this driver is designed to sustain. The FEA-optimised neodymium motor, ventilated gap, and double silicone spider ensure the output stays clean and consistent as power and excursion increase.
At 8.65 kg, the B&C 15NW100 weighs less than many ferrite 15-inch budget woofers — yet it handles 1000 W AES, reaches down to 35 Hz, and produces 97 dB sensitivity. For touring subs, compact high-output sub cabinets, and any application where a 15-inch driver needs to deliver genuine sub-bass authority with neodymium weight savings, this is the driver that tops the range.
Design and Construction of the B&C 15NW100
The B&C 15NW100 uses a 100 mm (4-inch) copper voice coil wound on a glass fibre former. Copper winding is the deliberate choice for this driver — denser and more conductive than aluminium, it provides better thermal transfer and contributes to the 1000 W AES power rating that makes the B&C 15NW100 the highest-power neo 15 in the range. The 25 mm winding depth operating in a 12 mm magnetic gap yields 9 mm of linear one-way excursion (Xmax) with an additional 11 mm of travel (Xvar) before mechanical limits.
The motor uses an FEA-optimised neodymium inside-slug magnet in a T-pole configuration, producing 1.2 T of flux density and a force factor (Bl) of 28 Tm. That 28 Tm figure is the highest Bl of any 15-inch driver in B&C’s entire product range — surpassing even the 15NA100’s 26.3 Tm and the 15NW76 8 Ω’s 25.5 Tm. FEA optimisation ensures the magnetic circuit extracts maximum flux concentration from the neodymium assembly, and the T-pole geometry focuses that flux where it does the most work — in the voice coil gap.
A ventilated voice coil gap allows air circulation around the coil, reducing power compression during the sustained high-power operation this driver is built for. Suspension is handled by a double silicone spider with optimised compliance and a triple-roll surround. The radial cone profile is tuned for low-frequency piston behaviour rather than upper-bandwidth extension — the right choice for a dedicated subwoofer that doesn’t need to reach into the mid-range.
TWP waterproof treatment on both sides of the cone provides full weather resistance for outdoor touring and festival deployments. At 8.65 kg and 181 mm deep, the B&C 15NW100 is the heaviest neo 15 in the range — the price for a 4-inch copper coil and the strongest motor assembly B&C fits in a 15-inch frame. A 4 Ω variant is also available for single-driver applications.
Performance and Applications for the B&C 15NW100
The B&C 15NW100 delivers 97 dB sensitivity and 2.1% reference efficiency across a 35 Hz – 1500 Hz bandwidth. The 35 Hz lower limit is the deepest of any neo 15-inch driver in B&C’s range, and the 33 Hz Fs means this driver produces meaningful output well below the tuning frequency of most 15-inch sub cabinets. At full rated power, the combination of 97 dB sensitivity and 1000 W AES generates peak output levels that rival many lightly loaded 18-inch subwoofer systems.
The Thiele–Small parameters define a driver built for vented enclosures tuned for sub-bass work. A Qts of 0.22 and an EBP of 143 Hz confirm this is a vented-box driver — the low Qts delivers tight, well-damped bass response when paired with the right enclosure alignment. B&C recommends a 100-litre (3.53 ft³) vented enclosure tuned to 40 Hz — a practical cabinet size that delivers deep, controlled sub-bass output without requiring an oversized box.
Compared to the 15NA100, the B&C 15NW100 trades 1 dB of sensitivity (97 vs 98 dB) and 500 Hz of upper bandwidth (1500 vs 2000 Hz) for 25% more power handling (1000 vs 800 W AES), a deeper Fs (33 vs 47 Hz), a stronger Bl (28 vs 26.3 Tm), and a tuning recommendation that’s 10 Hz lower (40 vs 50 Hz). The NA100 is a woofer that can reach low; the B&C 15NW100 is a subwoofer that stays low. Different tools for different roles in the signal chain.
Ideal applications for the B&C 15NW100 include:
- High-power compact subwoofer cabinets for touring and live sound
- Dedicated 15-inch sub systems where neodymium weight savings are critical
- Dual-driver sub cabinets using 8 Ω parallel pairs for 4 Ω loading
- Applications requiring genuine sub-bass extension below 40 Hz from a 15-inch format
- Permanent install subs in clubs, venues, and houses of worship

Conclusion – B&C 15NW100 Subwoofer Driver
The B&C 15NW100 is the most powerful neodymium 15-inch subwoofer driver in B&C’s range. The 1000 W AES power rating, 28 Tm force factor, and 33 Hz Fs place it in territory that no other neo 15 can reach — this is the driver you spec when a 15-inch sub needs to hit hard, reach deep, and sustain output at power levels that would overwhelm anything with a smaller coil or weaker motor.
The distinction between the B&C 15NW100 and the NA100 is worth understanding clearly. The NA100 is a woofer — exponential cone, 2000 Hz bandwidth, optimised for mid-bass efficiency and crossover flexibility. The B&C 15NW100 is a subwoofer — radial cone, 1500 Hz bandwidth, 33 Hz Fs, 28 Tm Bl, optimised for low-frequency authority and sustained high-power operation. If your 15-inch driver is handling sub duties below a crossover, the NW100 is the right tool. If it’s handling bass and mid-range in a two-way system, the NA100 is the right tool.
For high-power compact subs, touring sub cabinets, dual-driver configurations, and any 15-inch application where sub-bass output, power handling, and motor control are the non-negotiable priorities, the B&C 15NW100 is the neodymium 15-inch sub that sets the ceiling. It’s B&C’s best neo 15-inch subwoofer — and the 28 Tm force factor makes sure it stays in control no matter how hard you push it.
