DESCRIPTION

The CR-1 Active Subwoofer Crossover is designed to seamlessly integrate subwoofers with main speakers, enhancing dynamics, imaging, and low-level detail for a more cohesive sound experience. Developed by audiophiles, it offers precise tuning features and a commitment to analog signal purity.

It uses two banks of precision Linkwitz-Riley low-pass and high-pass filters, with DACs for superior tracking and left/right channel balance. The CR-1 also includes unique damping controls to improve acoustic summing and a rotary control for adjusting subwoofer-to-main speaker levels.

Built with high-quality components like precision resistors, audio-grade op-amps, and film capacitors, CR-1 minimizes distortion and noise. It’s adaptable for studio, mastering, and audiophile two-channel setups, and features a bypass for switching between two-channel and multi-channel systems. The CR-1 is the ultimate tool for subwoofer integration, delivering an exceptional listening experience.
