Unleash Chest-Pounding Lows With a High-Powered 2,200W Amp

The SUB 905-AS MK3 is engineered to deliver truly seismic bass, thanks to its robust 2,200W Class-D amplifier specifically designed to drive extreme sound pressure levels. With nearly instantaneous attack and enough headroom to push 133dB, you can expect massive impact that you not only hear, but physically feel. Even at ear-splitting volumes, the bass stays tight and defined. The efficient amp generates very little heat, eliminating the need for a cooling fan and potential failure points. All that matters is the bone-rattling bass coming from the muscular 15" woofer.

Experience Deep, Accurate Low End With a 15" Woofer and 3" Voice Coil

Outfitted with a formidable 15" woofer sporting a 3.0" voice coil, the SUB 905-AS MK3 subwoofer pumps out deep, accurate bass with authority. The oversized woofer displacement generates high SPL while providing enough surface area to maintain control even at extreme excursion levels. Combined with the robust voice coil, you get the best of both worlds - a driver that can unleash chest-thumping lows down to 40Hz along with the finesse to render intricate bass details in your mix. RCF engineers optimized the magnetic circuit for maximum flux density to improve transient response. The result is fast, punchy bass that keeps up with demanding tracks.

Proprietary DSP Ensures Linear Response and Low Distortion

At the core of the SUB 905-AS MK3 is Bass Motion Control, RCF's proprietary DSP technology that optimizes transient response and provides extended low-frequency linearity. Even when pushing the subs to their limits, the advanced processing ensures you get natural bass free of distortion or muddiness. You can crank up the volume without sacrificing clarity in the low end. The integrated protection system and custom limiter keep the woofer operating within a linear excursion range for uncompromised sound quality and reliability.

Fine-Tune Your Lows with Adjustable Crossover, Polarity and Delay

Dial in your perfect low-end sound with the SUB 905-AS MK3's flexible rear-panel controls. The adjustable crossover lets you seamlessly integrate with tops. Switch polarity to manage phase coherency. Set the optimal time alignment by tweaking the output delay in .1ms increments. Save and recall customized presets for quick configuration changes. Whether finessing your mix or tailoring your subs to the room, you have precision control at your fingertips.
