Description
JBL AC118S 18" High-Power Subwoofer System White
The JBL AC118S is a serious, compact subwoofer built for recording and mixing environments where deep low-end extension and clean power handling are non-negotiable. At 32.3 kg, it's substantial enough to deliver genuine bass authority yet portable enough for home studios, portable rigs, or permanent control-room installations. The robust plywood cabinet and dual Neutrik connectors signal a piece of equipment engineered to perform reliably in demanding professional tracking and monitoring scenarios.
Audio Performance
This system achieves 122 dB maximum SPL at 1 meter with a peak capability of 128 dB, powered by 450 W continuous / 900 W program / 1800 W peak handling. The 18-inch woofer with 75 mm voice coil reaches down to 32 Hz at -10 dB and 40 Hz at ±3 dB, providing articulate low-frequency response critical for accurate bass tracking and mix translation. System sensitivity of 95 dB at 1W/1m ensures efficient coupling with standard amplification, allowing controlled monitoring levels without excessive driver excursion that can muddy low-end detail.
Design & Build
The cabinet uses 18 mm multi-ply hardwood plywood construction with a vented, front-loaded configuration optimized for corner placement and room integration in studio spaces. Twelve threaded suspension points provide flexible mounting options for isolation or fixed positioning, while the powder-coated 1.5mm perforated steel grille with acoustic foam backing protects the driver without coloring the output during critical listening sessions. Dual Neutrik NL4MP connectors plus barrier trip terminals accommodate both speakon and traditional wiring approaches for flexible studio integration.
