JL Audio CR-1 Active Crossover

Achieving absolute alignment between main Speakers and a Subwoofer requires precise control over frequency division. The JL Audio CR1 active crossover is engineered to seamlessly blend your primary loudspeakers with your bass drivers, ensuring your complete Speakers - Subwoofer configuration performs with exceptional balance and clarity. By keeping the signal path entirely in the analogue domain, this unit preserves every subtlety of your source audio while eliminating low-frequency congestion.

Precision frequency division for clean sound integration:

At the heart of the system are dual banks of Linkwitz-Riley filters that separate high-pass and low-pass crossover points with high accuracy. Monolithic multiplying converters ensure left and right channels track each other perfectly across all frequency adjustments. This delivers pinpoint stereo imaging and smooth transition zones between your main drivers and Subwoofer system, preventing the frequency overlap that frequently compromises sound clarity.

Flexible damping and acoustic balance controls:

To adapt performance to your specific room acoustics, dedicated rotary controls adjust the damping of each filter bank. Fine-tuning these settings smooths out the crossover region where the subwoofer meets the main speakers. A central balance control allows immediate adjustments to bass output relative to the main loudspeakers, making it simple to dial in the ideal low-frequency foundation across various music genres. Crafted with a thick aluminum faceplate and high-grade internal components, the unit includes a managed bass input bypass for effortless switching between two-channel audio and multi-channel home cinema modes. Selected demonstration setups featuring code_CR1 or cataloged as title_Acrive Crossover are available as In Store Only opportunities within our instock equipment displays.
