The QSC E218sw is a high-performance direct-radiation passive subwoofer with two 18-inch aluminum-frame woofers, each rated at 800 watts, designed to produce crushing low-end for live performance with kick drum and bass in the PA, or for high-level, high-energy dance music. With 1600 watts of continuous power handling (6400 watts peak), 101 dB sensitivity and a peak SPL of 136 dB, the E218sw moves serious air for clubs, outdoor concerts and large event productions. Its 4-ohm nominal impedance means a single cabinet can be optimally powered by one amplifier channel, helping keep amplifier costs down. Attachment points for four optional casters make portable setups easier, and robust plywood construction stands up to the road. Like all E-Series loudspeakers, the E218sw performs superbly when paired with QSC GXD or PLD amplifiers or a TouchMix digital mixer, taking advantage of factory DSP tunings for live sound, DJ and karaoke applications. It is a go-to subwoofer for professional sound providers and DJs serving big events across Kenya.
