Features

Two-Way Driver Design: The Boston Classic CS 275 in-wall speaker utilizes a two-way driver design, featuring a 0.75" Mylar soft-dome tweeter for crystal clear highs and a 6.5" laminate film woofer with rubber surround for high-performance bass response. The CS 275 is designed to offer Boston's legendary sound with exceptional quality and value.

Spring-Clip Terminals: The CS 275 in-wall speaker is outfitted with a set of spring clips terminals that will accept up to 12AWG speaker wire.

Paintable Frame & Grille: Both the frame and grille can be painted to match the wall. A plastic paint mask is included to protect the speaker from being painted as well.

Applications: The Boston Classic CS 275 in-wall speaker can be installed in any room or hallway of your home in a distributed audio system, or used in a multichannel home theater system or a stereo-only 2ch music system.

In-Wall Installation: The Boston Classic CS 275 installs in a 7.375" (w) x 10" (h) cutout opening. The required depth to install the in-wall speaker is 3" from the mounting surface. Behind the opening there must be a 1.5" clearance around the top and bottom of the cutout to accommodate the mounting bracket. The mounting bracket secures the speaker in place using four screws. The wall material should be at least 1/4" thick.

Note: The NCB6 new-construction bracket (sold separately) can be used to simplify installation in new construction

IR Sensor Knockout: The CS 275 in-wall speaker has a knockout molded into the speaker baffle that will accommodate standard 0.5" diameter infrared (IR) sensor.
