With the Caliber CSB2 you listen to a clear sound, while you do not see large holes in your car doors. These speakers are not suitable for installation, but are supplied with mounting brackets. The installation is simple: you make 2 small holes on the spot where you want to place the speakers and screw the brackets. Due to the 3-way design, the sound also sounds clear at a high volume. The built-in drivers produce the low, mid and high tones separately. Put on your favorite dance song, turn up the volume and enjoy a powerful sound with clear melodies.
