Active Subwoofers for DJs, Bands and Venues

An active subwoofer adds low-frequency reinforcement to your sound system, giving kick drums, bass instruments and music playback greater weight. With an amplifier built into the cabinet, it provides a convenient way to extend your PA’s bass response without selecting a separate power amplifier for the subwoofer.

Prebeat’s range includes compact powered subs, dual-driver designs and larger 15-inch and 18-inch cabinets. Choose around your audience, musical requirements and the main speakers you already use.

Compact Powered Subwoofers for Portable and Installed Sound

Compact active subwoofers suit setups where transport space or room layout limits the size of the equipment. Smaller cabinets can provide useful bass support for presentations with music, acoustic performances and background music systems.

Low-profile designs offer further placement options in venues, while selected models are available in black or white. Check cabinet dimensions, ventilation requirements and access to controls when planning an installation.

Bass Reinforcement for DJ Sets and Live Music

For dance music, bands and busier event spaces, compare subwoofers by their usable output and low-frequency extension. Maximum sound pressure level and frequency response provide useful context alongside amplifier power.

Driver size alone does not determine performance. Cabinet design, processing and the number of subwoofers used also affect the result. For mobile DJs and event teams, balance your output requirements with cabinet weight, handling and vehicle space.

Matching an Active Subwoofer to Your PA Speakers

A well-integrated subwoofer should work smoothly with your main speakers. Check the available inputs, outputs and crossover facilities before choosing, particularly if you want to feed your main speakers from the subwoofer.

Some outputs provide a full-range link signal, while others apply a high-pass filter to reduce the bass sent to the main speakers. These functions vary between models, so confirm how your intended signal path will work.

Where provided, crossover, polarity and DSP controls help you adjust the system. Suitable settings and careful placement can improve the balance around the frequencies shared by the subwoofer and main speakers.

Connections and Setup

Active subwoofers need mains power and a suitable audio signal. Their line-level outputs generally feed another active speaker or amplifier input; they do not power passive speakers unless a dedicated amplified output is specified.

Explore our active PA speakers for matching main cabinets and signal cables for audio connections. For a coordinated package, browse PA system bundles, or choose passive subwoofers if you prefer external amplification.
