Sonance Professional Series PS-C63RT is a 70V/100V/8 Ohm selectable In-Ceiling Speaker that features a one-piece bezel-less grille that is magnetically secured and allows for a one-step painting process to simplify installation and minimize visual distraction.
The optional Square Grille Adapter allows speakers to match the aesthetic of square downlights and HVAC grilles to achieve continual sight lines.
A high-excursion 6” polypropylene woofer delivers effortless low bass extension, that exceeds most 8″ competitive products, while the pivoting chambered 1” soft dome tweeter can be directed to ensure accurate coverage, when speaker positioning is compromised.
A full-fidelity transformer delivers uncompromised sonic performance in either high (70V, 100V) or low (8 Ohm) impedance.
The PS-C63RT features a sealed metal enclosure, integrated cable and conduit clamping, removable Euroblock connector with loop-through, swing-open connecter cover and seismic attachment.
Additionally, the Sonance PS-C63RT is certified for UL 1480 and UL 2043.
