Overview Yorkville Sound's Paraline Series Active full range loudspeaker system delivers the clarity and precision of a complex line array system in a compact, user friendly format. Innovative cabinet design uses Yorkville Sound's proven Paraline high frequency lens technology pioneered in our flagship VTC Elevation Series line array cabinets. Two BMS 1.75-inch compression drivers mounted to the patented Paraline lens delivers a focused 15-dvertical dispersion and wide 110 degree horizontal coverage. The 6-inch woofers provide a tight and ultra responsive low frequency program. Ideal for mobile PA applications in venues where access to complex trussing or roof hangs isn't practical, the Yorkville PSA1 cabinet mounts quickly and securely on a typical speaker stand. Innovative dual position stand mount offers two potential cabinet angles for expanded setup options. Up to two PSA1 cabinets can be stacked safely and securely on a single traditional stand.
