Q-Audio QXOVER23 Stereo 2-Way / Mono 3-Way Active Crossover

The Q-Audio QXOVER23 is a professional-grade stereo 2-way or mono 3-way active crossover with an independent subwoofer output, designed to enhance the performance and control of multi-amplifier passive speaker systems. By separating bass and high frequencies before amplification, the QXOVER23 significantly improves system clarity, headroom, and speaker protection.

This 1U 19" rack-mountable unit fits seamlessly between your mixer and amplifiers, splitting the incoming signal via precision Linkwitz-Riley 24dB/octave filters. The crossover points are user-adjustable, and each output band includes individual gain controls, mute switches, and phase reversal switches—providing detailed system tuning and simplifying setup or troubleshooting.

An independent subwoofer output with a wide frequency control range from 10Hz to 235Hz further extends the crossover’s functionality, allowing it to operate as a 3-way stereo or 4-way mono system. A built-in 25Hz low cut filter protects your speakers from low-frequency distortion caused by inaudible energy spikes.

Unlike complex digital loudspeaker management systems, the QXOVER23 offers simple, hands-on control and pure analogue audio fidelity, with an impressive 20dB of signal headroom. It's ideal for live venues, clubs, performance halls, and installed sound systems requiring powerful, transparent frequency management and full-range control.
