SA3118 — Single-18 Active DSP Subwoofer
OVERVIEW
The SA3118 is a self-powered single-18-inch DSP subwoofer designed to complement AudioCenter SA-series full-range loudspeakers and other professional top cabinets. It is a practical choice for DJs, live sound, presentations, worship, event systems and fixed installations that need strong bass from one manageable cabinet.
LOW-FREQUENCY SYSTEM

• 1,000W RMS / 2,000W peak Class-D amplification
• 35 Hz–150 Hz frequency response (-10 dB)
• 128 dB continuous / 134 dB peak maximum calculated SPL at 1 meter
• 48 kHz DSP
• Selectable 80 Hz, 100 Hz and 120 Hz low-pass presets
SYSTEM INTEGRATION
The three low-pass settings let the SA3118 be matched to different top cabinets and system layouts. A rear-panel phase switch helps with crossover alignment. Female XLR input and male XLR output support simple signal linking through an active system.
