The RCF SUB8006-AS is a large-format, dual‑18-inch powered subwoofer designed for high‑demand live sound, capable of delivering extremely powerful low‑frequency reinforcement for touring systems, festivals, and large venues. It uses two 18‑inch woofers with 4‑inch inside/outside voice coils and is driven by a 2500‑watt RMS (5000‑watt peak) Class‑D amplifier module, producing up to 141 dB of max SPL with a usable frequency range from 30 Hz to 120 Hz. The cabinet includes DSP presets, delay control, phase options, and cardioid configuration settings, and its baltic birch construction, integrated rigging points, and compatibility with RCF HDL line‑array hardware make it ideal for professional deployment where high output and rugged build quality are essential.
