Yamaha DXS18XLF

The black Yamaha DXS18XLF is a 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 onboard D-XSUB LF 96 kHz DSP processor provides total bass management. The Normal mode is ideal for a balanced low-frequency response, while Boost mode provides a tighter and more focused bass with some extra punch. Xtended LF mode drops the low-end frequencies down even further for large bottom end. If using two or more subwoofers, the selection of Cardioid mode can effectively reduce stage volume, while increasing low-end output directed at the audience.

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 Yamaha DXS18XLF ships with a standard IEC power cord.

FEATURES

• Powered reflex subwoofer

D-XSUB LF Processing

• DXS XLF subwoofers are driven by 96 kHz high-power DSP processors and utilize dynamic EQ
• Onboard D-XSUB LF processing provides total low-frequency management
  • Normal mode:  Set for ideally balanced low-frequency response
  • Boost mode: Provides a tighter and more focused bass with some extra punch
  • Xtended LF mode: Drops the low-end frequencies down even further for a large bottom end
• Cardioid mode:
  • Works with two or more subwoofers
  • Effectively decreases the sound pressure on stage while increasing the bottom-end output directed towards the audience
  • Results in a much cleaner stage monitoring environment

DSP Protection

• DSP protection functions for maximum output and component longevity
• Active subwoofers ensure the combination of transducer and amplifier are matched and optimized for the best possible performance
• During development, Yamaha measured and tested the durability of each transducer and the overall amplifier output to set optimal limiter points using precise DSP control
• Employing many of the same protection functions used in high-end professional power amplifiers, Yamaha’s DSP consistently monitors the status of the power supply, power amplifiers, transducers, and signal levels to protect each component in order to maintain optimum performance while extending component life and usability
