The Sonance Professional Series PS-S43T MKII is a 4-inch two-way surface-mount loudspeaker engineered for indoor and outdoor commercial spaces where in-ceiling or pendant placement isn't possible. A high-excursion 4-inch polypropylene woofer pairs with a chambered 1-inch soft dome tweeter to deliver best-in-class performance in both 8-ohm and 70V/100V applications, with a transformer tap switch on the front-mounted connector panel.

The high-impact ABS enclosure is finished in a clean, unobtrusive industrial design and carries an IP45 rating with an extreme-temperature-resistant cabinet and corrosion-resistant powder-coated aluminum grille for long-term outdoor durability. The patented FastMount bracket system lets the enclosure pivot 180 degrees on the bracket for precise aim, and the front-mounted input connectors enable a close, low-profile mount to walls, beams, and overhangs. The PS-S43T MKII is UL1480A (UEAY) and UL2239 listed. The black finish suits restaurants, retail, fitness venues, and exterior installations.

Order replacement grilles, terminal covers, and optional brackets separately as fleet service stock — exterior installations consume small parts on a regular maintenance cycle.
