zZounds Gear Experts Say...

Make your speakers sound better than ever with the dbx 234S crossover. Equipped with Linkwitz-Riley 24dB per octave filters and output phase inversion.

Overview

The secret to making speakers sound great lies with the crossover you use. With the dbx 234S Crossover you'll get great performance, low-noise, rugged reliability and four decades of dbx knowledge and expertise in building the world's finest processors. The dbx 234S 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 dbx 234S 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.
