PS-C41RT 4" In-Ceiling Speaker

Sonance Professional Series PS-C41RT 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.

The PS-C41RT features a 4” polypropylene cone, butyl rubber surround woofer combined with a coaxially mounted .75” cloth dome, ferrofluid cooled high tweeter.

The PS-C41RT features extremely flat response for natural musically and intelligibility for voice, making it perfect for shopping malls, airports, schools, corporate, government, or anywhere an affordably-priced, aesthetically pleasing, and excellent sounding loudspeaker is required.

A full-fidelity transformer delivers uncompromised sonic performance in either high (70V, 100V) or low (8 Ohm) impedance.

Additionally, the Sonance PS-C41RT is certified for UL2043, UL1480, as well as EN54-24.
