Behringer DR18SUB Subwoofer ativo

Active 2400-Watt 18" PA Subwoofer with Built-In Stereo Crossover

The Behringer DR18SUB is a high-output active subwoofer crafted to anchor portable PA rigs, mobile DJ setups, club installs, and small-to-mid live-sound jobs demanding deep, controlled low end. Anchored by an 18" custom-engineered long-excursion driver and a 2400-Watt Class-D amplifier, the DR18SUB delivers up to 129 dB SPL across a 30 Hz to 150 Hz range, providing kick drums, bass lines, and electronic music with the physical punch needed to energize a room.

What stands out about this model is the integrated stereo crossover, a feature that eliminates the need for an external amp/crossover stack. Balanced XLR inputs and outputs, a selectable 90 Hz / 120 Hz crossover, phase-reverse switch, and Link/Xover output modes allow users to send high-pass content to satellite tops only. For working engineers and mobile DJs, this means one enclosure handles amplification, bass management, and top feeds—no extra rack gear required.

Standout Features

Combining Class-D amplification with DSP and an intelligent RMS/Peak limiter, this model safeguards its long-excursion driver during demanding sessions. The LF transducer, designed specifically for this enclosure, allows the cabinet to achieve high SPLs while maintaining low distortion—performance rarely seen at this price.

Amplification & Output Power — Class-D Efficiency for Touring Rigs

With Class-D topology, the amplifier remains lightweight and cool, so the DR18SUB can be moved by one person despite its 41 kg weight. Peak power headroom ensures DSP and limiters handle live transients without choking low frequencies.

• RMS Power: 800 W — continuous headroom for demanding program material
• The peak power rating of 2400 W gives the system enough punch for intense bass and kick peaks.
• Maximum SPL: 129 dB — suitable for mid-size clubs and outdoor events

Driver & Frequency Response — Deep Sub-Bass Down to 30 Hz

At the heart of the cabinet is the 18" long-excursion driver, tuned to deliver frequencies as low as 30 Hz—below the reach of most comparable cabinets. The wooden bass-reflex enclosure enhances bass efficiency, while steel grilles and recessed handles protect during transit.

• LF Driver Size: 18" — engineered for high SPL at low frequencies
• With a frequency range of 30 Hz – 150 Hz, it covers both sub-bass and the key crossover region for seamless integration.
• Enclosure: Wood, bass-reflex — optimized for low-distortion bass response

Connectivity, Crossover & Integration — Built-In Stereo Crossover

For users running 2.1 or satellite-plus-sub setups, the built-in crossover streamlines system configuration. Switchable cutoff points allow matching with different tops, and the phase switch helps address timing issues when sub and tops are spaced apart.

• Inputs: 2 x balanced XLR — stereo connection from mixer or controller
• Outputs: 2 x balanced XLR — select Link Mode for full-range or Xover Mode for high-pass output only
• Crossover Points: 90 Hz / 120 Hz — switchable to suit satellite response
• Standard 35 mm (1.375") pole socket accommodates satellite speakers with ease.
