{"product_id":"b-c-speakers-18sw115-422835","title":"18SW115","description":"\u003ch3\u003eA B\u0026C 18-Inch Designed for High-Level Bass Cabinets\u003c\/h3\u003e\u003cp\u003eThe B\u0026C 18SW115 fits within the logic of professional subwoofer speakers: delivering solid, stable, and reproducible bass even when the system operates for extended periods at high levels. Its 18-inch (46 cm) format clearly targets \"bass\" applications both front-facing and as reinforcement, with a performance-oriented approach (power handling, excursion, cooling) rather than domestic hi-fi. For cabinet designers, it is the type of transducer chosen when impact, a solid low-end foundation, and reliable operation are required.\u003c\/p\u003e\u003ch3\u003eWho Is the B\u0026C 18SW115 For?\u003c\/h3\u003e\u003cp\u003eThis speaker is intended for \u003cstrong\u003ecabinet builders\u003c\/strong\u003e, \u003cstrong\u003esound contractors\u003c\/strong\u003e, integration workshops, and technicians involved in \u003cstrong\u003erepair\/upgrading\u003c\/strong\u003e of professional subwoofers. It is particularly suitable if you want to load an 18-inch driver in a coherent volume for sound reinforcement (club, live, events) and achieve firm bass capable of following powerful amplifications without strain.\u003c\/p\u003e\u003cp\u003eIt may also interest advanced DIY projects, provided the load parameters, port tuning, and protection (filtering, limiters) appropriate for a transducer of this level are respected.\u003c\/p\u003e\u003ch3\u003ePerformance and Design: What Makes the Difference in the Field\u003c\/h3\u003e\u003ch4\u003ePower Handling and Thermal Stability\u003c\/h4\u003e\u003cp\u003eWith \u003cstrong\u003e3400W AES\u003c\/strong\u003e at 8 Ohms, the 18SW115 is designed to withstand sustained programs. Its \u003cstrong\u003e115 mm voice coil\u003c\/strong\u003e (4.5 inches) made of copper wire fits a typical architecture of high-end subwoofers: more surface area, better energy management capacity, and a useful reserve when peaks follow each other. The result: more consistent behavior, especially appreciated in intensive use (long sets, high temperature, heavy compression).\u003c\/p\u003e\u003ch4\u003eDeep Bass, Tuning, and Recommended Volume\u003c\/h4\u003e\u003cp\u003eThe manufacturer specifies a \u003cstrong\u003erecommended enclosure volume of 150 liters\u003c\/strong\u003e with a \u003cstrong\u003etuning at 35Hz\u003c\/strong\u003e. This guideline provides a clear framework to design an \"infra\/low\" oriented cabinet: aiming for solid extension and bass that remains clear. The \u003cstrong\u003eFs at 32Hz\u003c\/strong\u003e supports this by enabling effective reproduction of low frequencies when the enclosure and tuning are properly optimized.\u003c\/p\u003e\u003ch4\u003eMechanical Control: Excursion and Suspension\u003c\/h4\u003e\u003cp\u003eThe 18SW115 features an \u003cstrong\u003eXmax of 11.9 mm\u003c\/strong\u003e, sized for the high demands typical of a subwoofer. The \u003cstrong\u003etriple roll suspension\u003c\/strong\u003e contributes to excursion stability and control maintenance as levels increase. The \u003cstrong\u003edouble siliconized spider\u003c\/strong\u003e enhances consistency and mechanical durability over time, a crucial point to limit performance variations between gigs or after many hours of use.\u003c\/p\u003e\u003ch4\u003eReliability and Environmental Resistance\u003c\/h4\u003e\u003cp\u003eThe \u003cstrong\u003eradial cone\u003c\/strong\u003e benefits from a \u003cstrong\u003ewaterproof treatment front and back\u003c\/strong\u003e, useful for better resistance to humidity, condensation, and transport stresses. For systems regularly taken out (truck, setup\/breakdown, stage), this kind of detail contributes to the transducer's longevity and performance stability.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical
