A passive 2-way surface-mount loudspeaker for installations that demand more output. The SL4230 brings serious headroom and full-range articulation to retail floors, restaurants and worship spaces — anywhere coverage matters as much as clarity. BEHRINGER engineered it for set-and-forget reliability: robust transducers, protected crossover, and mounting hardware that takes the guesswork out of integration. Voiced to translate music and speech with equal honesty. Now obsolete — see our current install range.
