dbx 223xs Stereo 2-Way/Mono 3-Way Crossover with XLR Connectors
Description
dbx 223xs Stereo 2-Way/Mono 3-Way Crossover with XLR Connectors
The dbx 223xs is a precision audio crossover built on four decades of dbx engineering expertise. Its compact 1U-style chassis houses professional-grade components with solid click controls and high-quality XLR connectors, delivering the tactile confidence of a workhorse processor. This dual-channel crossover separates audio signals with surgical precision, directing specific frequency bands to their intended speaker drivers while freeing amplifiers from unnecessary signal content and reducing distortion—essential tools for the demanding gig environment.
Signal Processing & Filtering
The 223xs employs Linkwitz-Riley 24dB per octave filters—the professional standard in crossover design—to cleanly separate frequency ranges without phase shift artifacts. Each output features independent level control, phase inversion capability, and a 40 Hz low-frequency cut filter; the subwoofer output can sum both channels in mono, simplifying low-end management in complex live setups and letting you focus on your performance rather than signal routing.
Live Reliability & Audio Performance
Noise performance is exceptional: 106dB dynamic range unweighted and THD+Noise below 0.004% at +4dBu ensure transparent processing with no audible artifacts that cloud your tone on stage. Interchannel crosstalk measures below -80dB across the audible spectrum, guaranteeing complete channel isolation in stereo applications—the kind of isolation that keeps your signal intact through the longest gigs.

Reviews
At a Glance
The dbx 223xs is a precision stereo 2-way or mono 3-way crossover that splits audio signals across multiple speaker drivers with Linkwitz-Riley 24dB-per-octave filtering—the professional standard for clean, phase-coherent crossovers. Built for live-sound engineers and venue operators, it delivers transparent signal separation with negligible noise and distortion, independent level control per output, and a mono summing option for subwoofer management that simplifies complex PA rigs. Choose it for rock-solid reliability on tour, in installed venues, or monitoring setups where transparent audio and bulletproof operation matter.
Frequently Asked Questions
What is a crossover and when would I need one?
A crossover separates audio into frequency bands and routes them to different speaker drivers (tweeters, woofers, subwoofers) to optimize playback and reduce distortion. You need one in multi-driver speaker systems, PA setups with separate subwoofers, or studio monitoring chains where you're integrating a subwoofer with nearfield monitors.
What's the difference between stereo 2-way and mono 3-way operation?
Stereo 2-way mode processes two independent audio channels, each split into two frequency bands (high and low). Mono 3-way sums both inputs and splits the result into three frequency bands (low, mid, high), useful for full-range PA systems or large monitoring rigs.
Can I use this to add a subwoofer to my studio monitors?
Yes. The 223xs has independent level control, phase inversion, and a low-cut filter on each output, plus the ability to sum both channels to a mono subwoofer output—everything needed to integrate a sub seamlessly into a stereo monitoring setup.
What are Linkwitz-Riley filters and why do they matter?
Linkwitz-Riley 24dB-per-octave filters are the professional standard for crossovers because they provide clean frequency separation without phase shift artifacts that can cause comb filtering or imaging issues. This ensures accurate playback whether you're mixing, monitoring, or running live sound.
What's included in the box and what are the dimensions?
The 223xs arrives ready to mount in a 19-inch rack (1U height, 6.9 inches deep, 1.75 inches tall) with balanced XLR connectors on all inputs and outputs. It requires 15W power from a standard 100–230 VAC outlet and operates at 50 or 60 Hz.
