223 (discontinued)
More sound to your amps and speakers
The secret to making speakers sound great lies with the crossover you
 use. With the dbx® 223s Crossover you'll get great performance, ultra 
low-noise, rugged reliability and four decades of dbx knowledge and 
expertise in building the world's finest processors. The 223s uses 
precision filters to separate the audio signal and direct the correct 
frequencies to your loudspeaker drivers. By directing only the specific 
frequency bands to each speaker driver the 223s leaves your amplifiers 
free to use their full power on the usable signal eliminating distortion
 and giving your PA system a cleaner and better sound.
The dbx 223s is a dual channel crossover with all the features you 
would expect from a professional product. It features Linkwitz-Riley 
24dB per octave filters, independent output gain controls for level 
matching, output phase inversion, 40 Hz low cut filter, and optional 
mono summing of the low frequency (subwoofer) output. Everything in the 
design exudes great precision from the solid "click" controls to the 
high quality 1/4" TRS inputs and outputs.
