Sonance R1CSUR – Reference In-Ceiling Surround Speaker

Product Overview

The Sonance R1CSUR is the Reference Series in-ceiling surround speaker built to pair with the R1C in-ceiling LCR model. Its dual-driver array is designed to deliver diffuse surround imaging from the ceiling.

Product Description

The R1CSUR uses two 1-inch ferrofluid-cooled ceramic dome tweeters along with two 5.25-inch carbon fiber/Rohacell woofers and two 5.25-inch carbon fiber/Rohacell midrange drivers, handling 5 to 150 watts RMS with a 70Hz-30kHz frequency response and 90dB sensitivity (2.83V/1m). At 13.78 by 13.78 by 7.56 inches with a 12.375-inch round cutout, it needs a deeper ceiling cavity than a standard in-ceiling speaker, so installers should confirm joist and cavity depth before cutting in. As part of the Sonance Reference Series, the R1CSUR is designed to fit standard ceiling cavities and can be mixed and matched with the R1C and other Reference models to complete a surround layout, and it pairs with Sonance DSP amplifiers for custom-tuned performance. Integrators building an in-ceiling speaker theater layout typically pair the R1CSUR with the R1C for front and surround duty.
