Sonance R1SUR – Reference In-Wall Surround Speaker

Product Overview

The Sonance R1SUR is the Reference Series in-wall surround speaker built to pair with the R1 LCR model. Its dual-driver array is designed for diffuse surround imaging in home theaters and media rooms.

Product Description

Unlike the single-coaxial-driver R1 LCR speaker, the R1SUR uses a symmetrical array of two 1-inch ferrofluid-cooled ceramic dome tweeters, two 3-inch carbon fiber/Rohacell midrange drivers, and two 5.25-inch carbon fiber/Rohacell woofers, which is a layout suited to producing diffuse, enveloping surround sound rather than a single point source. It handles 5 to 150 watts RMS, with a frequency response of 70Hz-30kHz and sensitivity of 90dB (2.83V/1m). Dimensions run 8.88 by 21.75 by 3.88 inches, with a 7.5 by 20.5-inch cutout, so the R1SUR needs a wider bay than a standard LCR speaker. As part of the Sonance Reference Series, it is designed to fit standard wall or ceiling cavities and can be mixed and matched with the R1 and other Reference models to complete a full surround layout, and it pairs with Sonance DSP amplifiers for custom-tuned performance. Integrators building a full in-wall speaker theater layout commonly pair the R1SUR with the R1 for front and surround duty.
