Do you want to listen to a clear sound in the car, but do not see large holes in your doors? Then choose the Caliber CSB3. With the included mounting brackets you can place them in any desired location, such as on your parcel shelf. The sound is clear and powerful from any position. Due to the 2-way design, the low and high tones are separated. For example, the melodies and vocal lines of a song also sound pure at a high volume.
