Introducing the B&C Speakers 15NBX100—a powerhouse 15-inch woofer crafted for precision and punch in low-frequency sound. At its core is a 4-inch copper voice coil with a ventilated gap, capable of handling up to 2000 watts peak (1000 W RMS) at 4 ohms. With a frequency response spanning 35 to 1500 Hz and a sensitivity of 95 dB, it delivers rich, impactful bass. Engineered for clarity, it features a double silicone spider for enhanced control, an aluminum demodulating ring to reduce distortion, and a neodymium inside slug magnet with a T-pole design for efficient magnetic flow. The cone is treated with TWP waterproofing on both sides, ensuring resilience in demanding environments. Performance specs include a 37 Hz resonance frequency, a generous 855 cm² piston area, and a moving mass of 176 g, supported by a 109.6 dm³ compliance volume. Its motor strength reaches 22.69 Tm, with a 3.6-ohm resistance and 1.58 mH inductance, making it ideal for vented enclosures thanks to its 10 mm excursion and 123 Hz EBP. For optimal results, it’s recommended to mount this woofer in a 114 dm³ (4 ft³) enclosure tuned to 35 Hz. Installation is straightforward with a 15.5-inch overall diameter, 13.9-inch baffle cutout, and 16.7-inch bolt circle diameter. It has a depth of 7.05 inches and a flange thickness of 0.55 inches, occupying 0.21 ft³ of internal air volume. Weighing 18.85 pounds, it ships securely in a 16.73 × 16.73 × 8.82-inch box, with a total shipping weight of 21.72 pounds. This woofer is built to perform—and built to last.
- FEATURES : This powerful woofer is built for deep, accurate bass, featuring a 4-inch copper voice coil and handling up to 2000 watts of continuous power. With a frequency range of 35 to 1500 Hz and 95 dB sensitivity, it delivers strong low-end performance. Its design includes a double silicone spider for improved control, a ventilated voice coil gap to reduce power compression, and an aluminum demodulating ring to minimize distortion for cleaner sound.
- SPECIFICATIONS : This 15-inch woofer is designed for powerful bass performance, featuring a 4-inch copper voice coil with a 25 mm winding depth on a glass fibre former. It supports up to 2000 watts of continuous power at 4 ohms, with a frequency range of 35 to 1500 Hz and 95 dB sensitivity. Its 11 mm magnetic gap and 1.1 T flux density enhance efficiency, while the TWP waterproof cone treatment ensures durability in tough conditions.
- PARAMETERS : This 15-inch woofer delivers powerful and precise bass with a 37 Hz resonance frequency and a large 855 cm² piston area.
