Know before you buy
Most in-ceiling speakers fire sound straight down, which can create a disjointed listening experience. The RCS II is engineered to project audio at an angle directly toward your listening position, resulting in a more accurate, immersive soundstage that mimics traditional bookshelf speakers.
Yes, the grille is designed to be paintable. This allows you to blend the speaker seamlessly into your ceiling for a clean, flush-mount aesthetic that hides the hardware.
Absolutely. Because it is built with reference-grade components and focuses on precise imaging, it is well-suited for use as a front or surround channel in a high-performance home theater system.
Yes, these are passive, wired speakers. You will need to connect them to an external AV receiver or amplifier to provide the necessary power and signal.
The dual 5.25-inch woofers deliver a rich, detailed low-end response that is impressive for an in-ceiling unit. However, for deep, cinematic bass in a large home theater, we recommend pairing them with a dedicated subwoofer.
They are designed for straightforward installation, but because they are flush-mount, you will need to cut a precise hole in your ceiling and run speaker wire through your walls or ceiling joists. If you aren't comfortable with basic carpentry and wiring, professional installation is recommended.
