The Mackie Thump18Sv4 18" Professional Powered Subwoofer is a powered subwoofer designed for extending low-frequency performance in PA systems. Combining a 1400W Class-D amplifier with a high-performance 18-inch woofer it delivers deep bass with a maximum SPL of 132 dB and low-frequency extension down to 25 Hz. Selectable high-pass modes make it easy to match the subwoofer with a wide range of loudspeakers while a variable crossover option allows for more precise tuning. With stereo XLR inputs and outputs plus the ability to chain additional subwoofers it integrates easily into live sound setups. Built-in carry handles and a robust enclosure make it suitable for regular transport and use.
