Using this Lowell speaker is easy. First, find a suitable location for mounting. Make sure the mounting surface can support the speaker's weight and the mounting bolt circle fits properly. Connect the speaker to your audio system according to the power requirements, using the taps on the 70V transformer (1, 2, 4, 8W) as needed. When in use, avoid exposing the speaker to extreme temperatures, moisture, or direct sunlight. For maintenance, keep the speaker clean by gently wiping it with a soft, dry cloth. Check the connections regularly to ensure they are secure. If you notice any problems, refer to the user manual or contact customer support.
