B&C Speakers 15FW88 15-inch Ferrite Woofer Cone WP Waterproof Front Side 4 Ohm Audio Speaker 3.5 in. Ventilated Voice Coil Gap 700 Wrms 1400 Watt Peak

.Meet the B&C Speakers 15FW88—a rugged and high-performance 15-inch ferrite woofer crafted for today’s demanding loudspeaker systems. At its heart lies a 3.5-inch aluminum voice coil paired with a high-flux ferrite magnet, capable of delivering up to 1400 watts peak (700 W RMS) at 4 ohms. With a wide frequency response from 49 Hz to 3000 Hz and a sensitivity of 98 dB, this speaker excels in both low and midrange output. Its ventilated voice coil gap helps reduce power compression, while a double silicone spider and aluminum demodulating ring work together to minimize distortion, making it a perfect fit for two-way setups. Engineered for clarity and durability, the woofer features a 0.43-inch magnetic gap and 1.04 T flux density, along with a WP waterproof cone treatment on the front side to withstand tough environments. Performance parameters include a 49 Hz resonance frequency, 855 cm² piston area, and a moving mass of 106.8 g, supported by a compliance volume of 103.7 dm³. With a motor strength of 19.27 Tm, 5.2-ohm resistance, and 0.81 mH inductance, it offers tight control and clean reproduction. Its 8 mm excursion and 109 Hz EBP make it ideal for vented enclosures. The design incorporates a triple roll surround and exponential cone shape for enhanced stability, supported by a double silicone spider and a T-pole ferrite magnet structure. For optimal performance, it’s recommended to install the woofer in a 130 dm³ (4.59 ft³) enclosure tuned to 45 Hz. Installation is straightforward thanks to its 15.47-inch overall diameter, 14.06-inch baffle cutout, and 14.61-inch bolt circle diameter. With a depth of 6.85 inches and a flange thickness of 0.55 inches, it occupies just 0.12 ft³ (3.5 dm³) of internal air volume. The unit weighs 19.84 pounds and ships securely in a 16.73 × 16.73 × 8.82-inch box, totaling 22.71 pounds for shipping. This woofer is built to deliver—and built to last.
