A passive 2-way surface-mount speaker that punches above its footprint. The SL4220 pairs a high-excursion woofer with a smooth HF driver for clear speech and musical detail across hospitality, retail and meeting-room installs. BEHRINGER built it to be invisible in operation and effortless to install — integrated mounting points, paintable enclosure, and a protected crossover for years of daily duty. Honest performance, no compromises. Now obsolete — see our current install range for the successor.
