Using your Bogen ACD2X2 ceiling speakers is easy. First, choose the right ceiling size (either 2ft x 2ft or 2ft x 4ft). If you're using a 2ft x 4ft ceiling, use the included support rail crossbar. Install the speaker in the ceiling as per the instructions. You can adjust the volume with the front - mounted, recessed volume control. For safety, make sure the speakers comply with UL - 2043 regulations. When it comes to maintenance, keep the speakers clean. You can gently wipe the non - reflective bright white grille with a soft cloth. Avoid using harsh chemicals as they may damage the finish.
