The Yamaha SW218V Club Series V Subwoofer gives you professional quality bass sound. Gigging bands, mobile DJs, and houses of worship helped make the first 4 generations of Yamaha Club Series Speakers incredibly popular. The refinements of generation V continue this success story with larger enclosures for improved low-frequency performance, improved drivers for higher power handling, redesigned crossovers, stronger grilles, and dual Speakon and 1/4″ connectors. With professional features, excellent sonic performance and great sound. Club Series loudspeakers deliver premium quality night after night.
