The Yamaha DXS15 Active Subwoofer delivers powerful yet focused low end sound, reaching frequencies as low as 42Hz, giving your music an extra helping of deep, heavy bass tones. The DXS's fully optimized band-pass design combines with its powerful Class-D amplifier, long travel 15" woofer, and formidable DSP to deliver a tight, impressive bass with outstanding depth and high power output. A great expansion to an already existing set up, the Yamaha DSX15 Active Subwoofer outputs an impressive sound for the compact size of the unit. An integrated 950W Class D amplifier and built in DSP offer precise and professional control for great live use. Left and right XLR inputs are available, along with XLR thru outputs. World class DSP technology allows control of several EQ curves and a low pass filter, easily usable with switches on the back of the Yamaha DXS 15 active subwoofer. The use of this feature can make for extremely effective and powerful sound that can improve the performance of a standard PA system thanks to the extended range on offer.
