B&C Speakers 15SW115-8 Pro Audio 15-inch Subwoofer Woofer Cone TWP Waterproof Both Sides 1700 Wrms 3400 Watts Peak 4.5" Ventilated Voice Coil Gap 8 Ohms

The B&C Speakers 15SW115-8 is a professional-grade 15-inch subwoofer engineered for robust low-frequency performance. It delivers up to 3400 watts peak and 1700 watts RMS, supported by an 8-ohm impedance and a 4.5-inch ventilated copper voice coil that ensures efficient heat dissipation. With a frequency response of 35 to 1500 Hz and a sensitivity of 96 dB, it produces deep, powerful bass with clarity and control. Key components like the double silicone spider, aluminium demodulating ring, and triple roll surround help reduce distortion and compression. Built for durability, it features a radial cone treated with TWP waterproofing on both sides and a glass fibre former, making it suitable for both indoor and outdoor environments. Its motor system includes a 30 Tm Bl factor, 5.2-ohm resistance, and 1.8 mH inductance, delivering precise control and strong magnetic performance. Optimized for vented enclosures, it has a 35 Hz resonant frequency, 13.5 mm excursion, and is best used in a 90 dm³ (3.2 ft³) cabinet tuned to 40 Hz. The subwoofer measures 15.5 inches in diameter, 7.6 inches in depth, and weighs 24.47 lb, shipping in a compact box for safe and efficient transport.
