RCF SUB 8003-AS MK3 2,200W 18-inch Powered Subwoofer

With a seamless combination of portability, power, and sonic flexibility, the RCF SUB 8003-AS MK3 lives up to even the most demanding live sound applications. This subwoofer’s 18-inch woofer, 4-inch voice coil, and 1,100 RMS (2,200 peak) digital Class D amplifier push out up to 135dB max SPL of floor-rumbling low-end, making the SUB 8003-AS MK3 an ideal choice for users looking to upgrade their system’s low-end potential seriously. With the MK3 iteration, RCF introduced a new dimension of bass-sculpting: the Bass Motion Control system. This proprietary supplement to their onboard DSP extends linearity and bolsters fidelity to ensure each note is brimming with presence and laser-focused clarity. Moreover, a host of fine-tuned features, including selectable gain, equalization, phase, crossover, delay, and cardioid control, offer a formidable range of ways to adjust your sound to excel in any environment.

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.We are highly impressed by their crisp, fast attack and superior transient response — it’s a design that maximizes your RCF subwoofer’s 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 8003-AS MK3 with a top-of-the-line cabinet construction to match its top-tier sound. Multi-ply hardwood comprises its core, while a polyurea finish massively improves resistance 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, making painless work of set-up, tear down, and multi-sub stacking.
