Active Subwoofer Crossover

The lucky few who have heard a well-integrated subwoofer in a great audio system know that the subwoofer's 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.

Once you use it you’ll find it indispensable.

The ultimate tool for subwoofer integration

Over the years, JL Audio have calibrated many subwoofer systems in highly critical listening environments, and have been frustrated by the limitations of active crossovers we have worked with. Tired of struggling with "blunt instruments", JL Audio felt that a higher precision tool was needed, so they decided to build it and call it the "CR-1". When properly set up, JL Audio's CR-1 creates a listening experience in which the subwoofers and main speakers become one, delivering a cohesive and compelling sonic presentation.

The CR-1 Active Subwoofer Crossover has been designed by audiophiles, for audiophiles. JL Audio believe it has no equal, offering a powerful combination of subwoofer/satellite tuning features, and a complete commitment to analog signal purity.

The CR-1 is built around two banks of precision Linkwitz-Riley low-pass and high-pass filters. Multiplying DACs with monolithic ratio matching are employed to adjust the analog circuit's filter frequencies. This offers superior tracking behavior and far more precise left/right channel balance, compared to conventional approaches.

Another of CR-1's unique and powerful features is a pair of rotary controls that control the damping of each filter bank. These damping controls dramatically improve the acoustic summing through the crossover region, by compensating for each speaker system's frequency response. At the center of the front panel, a single intuitive, rotary control permits quick adjustment of the relative level between the subwoofer(s) and main speakers.

To minimize distortion and noise, CR-1 employs top-grade component parts in its all-analog audio circuitry: 1% precision resistors, JFET-input audio-grade op-amps, polypropylene film-and-foil capacitors and metallized-polypropylene film capacitors, to name just a few. Like all JL Audio products, the CR-1 is built in their own factory in the U.S.A. This ensures top quality and dependability.

CR-1's input-output design makes it equally adaptable to studio, mastering suite or audiophile two-channel playback environments. To accommodate dual-mode systems, we also include a bypass feature that engages a pass-through from a dedicated "Managed Bass Input" on the rear panel, to the CR-1's subwoofer outputs. This makes it convenient to switch from two-channel to multi-channel mode.

Who is this for?

Who is this for?

The CR-1 is purpose-built for the discerning audiophile who's already invested in quality full-range speakers and wants to add serious subwoofer integration—whether that's a single JL Audio Fathom or Gotham, or a pair of high-performance subs. If you're running a stereo system in a dedicated listening room or a larger open-plan space where bass management has always felt like a compromise, this active crossover changes everything. You'll need at least three channels of amplification: two for your main speakers and one (or more) for your subwoofers, making this ideal for those running separate power amplifiers or willing to dedicate channels accordingly.

This isn't a set-it-and-forget-it solution for casual listeners. The CR-1 is for the hands-on enthusiast who understands that proper integration between mains and subs requires precision—adjustable crossover slopes, phase correction, and the ability to time-align drivers in the acoustic domain. If you're the type who's already experimented with subwoofer placement, played with phase settings, and still felt something was missing, the CR-1's comprehensive control set will feel like exactly what you've been searching for. It sits between your preamplifier and power amplifiers, giving you surgical control over the handoff between your speakers and subs.

You'll appreciate the CR-1 most if you value transparency and flexibility over convenience. Whether you're running vintage tube amplifiers with modern subs, a fully balanced solid-state rig, or anything in between, its XLR and RCA connectivity adapts to your system. This is for listeners who demand that their subwoofers disappear sonically—not by turning them down, but by integrating them so seamlessly that you simply hear more music, more space, and more of what's actually on the recording.

Reviews

The CR-1 confers a big advantage by splitting the frequency band with a true high-pass and a low-pass crossover. There’s very little overlap between the subwoofer and main speakers around the crossover point, eliminating the unpredictable result of having two different sources reproducing the same frequency band.
