AudioCenter S Active DSP Subwoofers
The AudioCenter S active subwoofer family provides self-powered low-frequency reinforcement for professional PA, DJs, live sound, rental, event production, houses of worship and fixed installations. Choose the S3118A single-18-inch model or the S3218A dual-18-inch model above; the selected option updates the exact product image, SKU, price and detailed specifications.
Both models use customized 18-inch drivers with 4-inch voice coils, Class-D amplification and 48 kHz DSP. Three selectable low-pass presets—80 Hz, 100 Hz and 120 Hz—make it easier to match the subwoofer to different top cabinets, venues and music styles. A rear-panel phase switch helps with system integration, while XLR input and output allow the signal to be linked through to additional powered loudspeakers.
