The Yamaha DXS18XLF-D is a Dante-equipped, powered subwoofer designed for extending the low frequency of full-range speakers and is well suited for use with any of the DZR-series powered loudspeakers. The 1600W Class-D amplifier powers the 18" woofer to provide a frequency range of 30 to 150 Hz (-10 dB) with a maximum SPL of 136 dB. The rear panel offers two combo XLR-1/4" inputs with XLR thru/outputs and dedicated level controls. A USB port allows for system upgrades and preset configuration and backups. The DXS18XLF-D is equipped with an additional panel with two etherCON connectors (2-in/2-out) for interfacing with other Dante-compatible equipment such as other speakers and Yamaha's CL/QL/TF digital mixing consoles.
