{"product_id":"b-c-speakers-15-sw-115-422824","title":"15 SW 115","description":"\u003ch3\u003eA 15-inch B\u0026C focused on SUB: performance at the core of the range\u003c\/h3\u003e\u003cp\u003eThe B\u0026C 15SW115 is a 15-inch (38 cm) bass driver clearly developed for the sub and low-midrange register, where acoustic pressure, mechanical durability, and excellent thermal stability are expected. Its 15-inch format makes it a versatile choice for many PA enclosures, offering an interesting balance between size, low-frequency extension, and efficiency.\u003c\/p\u003e\u003cp\u003eWith its neodymium motor and robust design, it fits within B\u0026C's \"pro\" approach: achieving a high level of performance without compromising reliability, for speakers intended to operate long-term at high levels.\u003c\/p\u003e \u003ch3\u003eWho is it for and what for: PA subwoofer, serious DIY, and professional integration\u003c\/h3\u003e\u003cp\u003eThis transducer is aimed at integrators, speaker manufacturers, service providers, and DIY enthusiasts who want to build or upgrade a bass cabinet capable of intensive use: clubs, live events, mobile systems, fixed installations, and dedicated bass monitors. Its low starting response (Fs 35 Hz) and excursion capability (Xmax 13.5 mm) make it particularly suitable for sub-heavy programs (electro, hip-hop, live music with strong rhythm sections), while maintaining clarity.\u003c\/p\u003e\u003cp\u003eThe recommended enclosure volume of 90 liters with a tuning at 40 Hz provides clear guidance for speaker design: a realistic cabinet volume suited to a high-performance bass-reflex configuration, without resorting to oversized enclosures.\u003c\/p\u003e \u003ch3\u003eDesign \u0026 key points: power, control, and endurance\u003c\/h3\u003e\u003ch4\u003e4.5-inch (115 mm) voice coil: handle power without losing control\u003c\/h4\u003e\u003cp\u003eThe 4.5-inch (115 mm) copper wire voice coil directly contributes to power handling (3400 W AES) and stability during prolonged use. In a subwoofer cabinet, this is an essential criterion: the coil must remain efficient as levels rise and maintain good transient control to avoid \"soft\" or overwhelming bass.\u003c\/p\u003e \u003ch4\u003eTriple roll suspension \u0026 Xmax 13.5 mm: moving air cleanly\u003c\/h4\u003e\u003cp\u003eThe triple roll suspension combined with a 13.5 mm Xmax allows for large excursions typical of sub frequencies. The result: more air displacement, hence greater impact and depth, while maintaining a mechanical design built to withstand repeated high-level stresses.\u003c\/p\u003e \u003ch4\u003eDouble siliconed spider: mechanical stability and consistent behavior\u003c\/h4\u003e\u003cp\u003eThe double siliconed spider helps center and stabilize the moving assembly. This architecture aims for more consistent behavior under heavy use, helping to keep bass clear with fewer mechanical drifts over the course of a session.\u003c\/p\u003e \u003ch4\u003eRadial treated cone: reliability in real-world conditions\u003c\/h4\u003e\u003cp\u003eThe radial cone with waterproof treatment front and back is a real advantage for field use: humidity, temperature variations, storage, transport. This treatment protects the cone and maintains its properties over time, where bass cabinets are often put under heavy strain.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical
