Sonance SA4-66 Complete Speaker Kit – 4-Inch In-Wall Speaker

Product Overview

The Sonance SA4-66 Complete Speaker Kit is a Small Aperture Series in-wall speaker built around a 6.5-inch woofer and a 2-inch aluminum wide-band module, housed in a rigid wood enclosure, and finished with a micro trim grille. It is designed for integrators who need full-range performance from a compact 4-inch wall opening, whether the aperture is limited by existing framing or by a client's aesthetic preference. The kit includes the enclosure, module, and grille as a complete, ready-to-install package.

Product Description

A 4-inch opening is one of the smallest apertures used for a serious in-wall speaker, and the SA4-66 is engineered specifically to get full-range sound out of that constraint by combining a 6.5-inch aluminum-cone woofer with a 2-inch aluminum wide-band module in a rigid wood cabinet. That combination produces a measured frequency response of 45Hz to 22kHz within +/-3dB, extending to 35Hz to 25kHz within +/-10dB, which is a wide range for a speaker that fits behind a 4-inch cutout. The module handles up to 125W maximum power with an 8-ohm impedance and 82dB sensitivity (2.83V/1m), giving integrators enough headroom for background and foreground music applications alike. Because the tweeter and midrange module is designed separately from the woofer and enclosure, Sonance offers modified cabinet options in shallow, narrow, or offset configurations for tight wall cavities, along with multiple trim accessories to change the finished look. This complete kit ships with the micro trim grille installed, so it is ready to specify wherever a discreet in-wall speaker is needed without sourcing the enclosure, module, and grille separately. The 22.95-inch by 10.2-inch by 6.38-inch enclosure footprint should be confirmed against wall cavity depth and stud spacing before rough-in.
