Powered 15" subwoofer.

The RCF SUB 705-AS II Active Subwoofer packs serious low-end power into a compact, portable enclosure. With a robust 1400W digital amplifier driving a 15" woofer, this sub delivers tight, controlled bass response suited for any venue. Its balanced XLR inputs and outputs make integrating into an existing PA system a breeze.

1400W Digital Amplifier Powers Deep Bass

At the heart of the Active Subwoofer is a powerful yet efficient 1400W digital amplifier. It produces high output with minimal distortion, resulting in remarkably natural and impactful bass. The amplifier's solid aluminum construction helps dissipate heat, ensuring reliable performance even under demanding conditions.

15" Woofer Reproduces Low Frequencies With Ease

The Active Subwoofer's 15" woofer is engineered to reproduce low frequencies with speed and control. Its large 2.5" voice coil provides minimal power compression at high output levels. The woofer's design and the optimized bass reflex cabinet allow for a flat, extended frequency response so you'll get tight, musical bass without boomy overtones.

Compact, Portable Enclosure

Despite its impressive power and performance, the Active Subwoofer has a surprisingly compact footprint. Recessed handles on either side make transporting this subwoofer easy, whether to a gig or just to a different room. Its integrated pole mount also allows you to stack it with a compatible full-range speaker for a simple yet high-quality PA system.

Simple Integration Into Existing Systems

With balanced XLR inputs and outputs, the Active Subwoofer can be connected to virtually any professional sound system. Adjustable settings like volume, crossover frequency and phase let you dial in the perfect blend of low-end for your application and room. Three LEDs display limiter, signal and status information for quick monitoring of system performance.
