RCF SUB 8004-AS Active High-Power Subwoofer

The SUB 8004-AS houses a single high-power, hypervented 18-inch woofer with a 4.0-inch inside/outside voice coil, driven by a 1250W RMS (2500W peak) digital amplifier module. It reaches 136 dB SPL across 30 to 120 Hz, giving a single cabinet the low-end weight of a much larger box.

The input board carries volume, deep/punch, high-pass and phase switches plus cardioid and time-delay settings, so it can be tuned in a stack without extra outboard gear. The Baltic birch plywood cabinet is stackable with ergonomic handles for fast load-in, and top and side pole receptacles let it carry a satellite speaker.
