The QSC E-Series E218sw is a high-performance direct-radiation subwoofer housing two 18-inch aluminum-frame woofers, built to deliver crushing low-end for live performance with kick drum and bass in the PA, or for high-level, high-energy dance music. Each driver is rated at 800 watts, giving the cabinet a total power capacity of 1600 watts continuous and 6400 watts peak. Sensitivity of 101 dB and a peak SPL of 136 dB mean the E218sw fills large rooms and outdoor stages effortlessly, while its 4-ohm impedance lets a single cabinet be optimally powered by one affordable amplifier channel. For portable use, the enclosure includes attachment points for four optional casters. Part of QSC's E Series Entertainment System, the E218sw reaches its full potential paired with QSC GXD or PLD amplifiers or a TouchMix digital mixer, using factory-tuned DSP presets for live reinforcement, DJ sets and karaoke.
