Like the TH-15A, the TH-18s was designed by the same speaker gurus who developed the SRM450v2s. Delivering 1000 watts of peak power, the TH-18s subwoofer offers many of the same benefits as the Thump full-range model. Powerful, efficient, and built-like-a-tank, the TH-18s subs complete the Thump system. They are also a great choice for use with Mackie's top-selling SRMv2s. "The Thump TH-15A has been very well received and with the addition of a powerful matched sub, the Thump system provides a great sounding, reliable full-range solution for budget-minded bands, DJs, clubs, churches and more," said Greg Young, Mackie brand director. With an 18" driver, 1000 watts of ground shaking power and ultra solid construction, the TH-18s will appeal to customers across the board. With light-weight, class-D power and massive low-end extension, not to mention an amazing price, the value is clear. The Thump TH-18s Powered Subwoofer is available now and has a U.S. MSRP of $879.99.
