The Highest Level of Professional Series Power

Designed for the most demanding of live sound applications, the RCF SUB 8006-AS is a 5,000W 2 x 18-inch powered subwoofer that clocks in at the very highest level of RCF’s low-end performance. Two massive 18-inch woofers with 4-inch inside/outside voice coils and a top-class 2,500W RMS (5,000W peak) digital amplifier push out a level of bass response that’s simply unmatched by any other RCF Professional Series sub. Moreover, the DSP-controlled input selection offers a variety of selectable presets and settings, including crossover, phase switch, deep/punch switch, cardioid, and output delay settings to dial in your sound. Wrap it all up in RCF’s tour-grade Baltic birch cabinet, and the SUB 8006-AS is the epitome of RCF’s world-class subwoofer might.

Top-shelf Class D amplifiers

RCF’s Class D power amplifiers represent a cutting-edge design that offers the utmost efficiency and power while retaining a tour-friendly lightweight design. Here at Sweetwater, we are highly impressed by their crisp, fast attack and superior transient response — it’s a design that maximizes your RCF speakers’ sonic potential. Moreover, a heavy-duty solid mechanical aluminum structure keeps the amplifier stable during transportation while also enhancing heat dissipation during heavy use.

Tour-grade cabinet construction

RCF has outfitted the SUB 8006-AS MKII with a top-of-the-line cabinet construction to match its top-tier sound. The cabinet is designed with high-quality birch plywood, then covered with a textured black finish that’s highly resistant to weathering, scratches, and the typical wear commonly encountered in live sound situations. Moreover, while RCF subwoofers are crafted for maximum SPL and low-end rumble, they’re also fine-tuned to remain extraordinarily portable and lightweight.

RCF SUB 8006-AS 5,000W Dual-18-inch Powered Subwoofer Features:

  • Extraordinarily powerful subwoofer that sits at the top of RCF’s Professional Series
  • Dual 18-inch woofers with 4-inch inside/outside voice coils push out a ground-shaking level of bass
  • 2,500W RMS (5,000W peak) digital amplifier offers up to 137dB max SPL for even the most demanding of live sound applications
  • DSP controlled input section with crossover, phase switch, deep/punch switch, output delay settings, and cardioid to adjust your sound for your respective application
  • Heavy-duty Baltic birch plywood cabinet and textured black finish are highly resistant to wear and tear
