ART CX311 2-Way Crossover with Subwoofer Output

Two-Way Active Crossover for Live Sound Systems

The ART CX311 is a professional two-way active crossover designed to manage frequency distribution in live sound and installed PA systems. It allows you to properly route low, mid, and high frequencies to the correct speakers, improving clarity, efficiency, and overall system performance in venues such as clubs, houses of worship, and event spaces.

Precision Frequency Management for PA Installations

At the core of the CX311 are fourth-order Linkwitz-Riley filters with a 24 dB per octave slope, ensuring smooth phase-coherent crossover points across all outputs. This design keeps low, mid, and high frequencies aligned, reducing phase issues and maintaining consistent sound coverage throughout the listening area.

Dedicated Subwoofer Output for Low-End Control

The CX311 includes a dedicated subwoofer output that simplifies integrating subs into a stereo PA system. This allows low-frequency energy to be sent directly to powered or passive subwoofers while higher frequencies are directed to full-range or mid/high speakers, resulting in tighter bass response and improved system headroom.

Built-In Low-Cut Filtering for Cleaner Sound

A selectable 30 Hz low-cut filter helps remove unwanted subsonic frequencies that can waste amplifier power and strain speakers. By filtering out unnecessary low-end rumble, the CX311 helps protect your system while improving clarity and efficiency in real-world live sound environments.

Rackmount Design Built for Touring and Install Use

Housed in a standard 1 RU rackmount chassis, the CX311 is designed for reliable operation in permanent installations and mobile sound rigs. Its durable construction and straightforward front-panel controls make it easy to integrate into existing systems while maintaining consistent performance show after show.

Optimized for Stereo Two-Way Sound Systems

Designed specifically for stereo two-way configurations, the CX311 works seamlessly with power amplifiers, powered speakers, and subwoofers. Whether used in a fixed installation or a portable PA, it provides predictable crossover behavior and dependable signal routing for professional audio setups.
