JL Audio CR1 Active Crossover

Description

The JL Audio CR1 Active Subwoofer Crossover provides the functionality required to integrate one or two subwoofers into your system. It features adjustable crossover frequency, slope, subwoofer / satellite level balance and ability to mono the subwoofer output signal.

It's a very transparent device, and works in the highest of high-end audio systems due to the use of high quality all-analog circuitry.

At Acoustic Frontiers we always prefer two channel systems with subwoofers, even if you have "full range" speakers. Properly integrated subwoofers improve sound quality in many ways. By using multiple subwoofers you can reduce modal resonance issues via room mode cancellation techniques. Subwoofers take the load off your main speakers and amplifiers, reducing distortion and improving low-level detail.

The lucky few who have heard a well-integrated subwoofer in a great audio system know that the effect is profound. While everyone expects the bass extension to improve, most are shocked at the transformation that occurs in the main speakers. They simply open up, delivering improved dynamics, superior imaging and more low-level detail. Many describe it as the greatest speaker upgrade they have ever made.

One of the great features of the CR-1 is it's ability to be used in a combined home theater / two channel system. It has a special managed bass input that bypasses the crossover in the CR1 for when you are using the home theater system (since bass management is done in the AVR or pre-pro).
