The D&B Audiotechnik Ci90 full - range two - way passive loudspeaker pair offers great audio performance. However, please note that the grille cloth is missing.

To use these D&B Audiotechnik Ci90 loudspeakers, first find a stable and flat place to put them. Connect the audio source to the speakers using appropriate cables. Turn on the audio device and adjust the volume to your preference. When using, avoid placing the speakers in a very humid or hot environment. For maintenance, keep the speakers clean by gently wiping them with a dry cloth. Since the grille cloth is missing, be extra careful not to let dust or small objects get inside the speakers.
