These Clair Bros 15CX loudspeakers come in a pair. They feature a 15 - inch LF driver and a 3 - inch HF driver, delivering high - quality sound. One minor issue: on one speaker, the head of one of the back plate screws has broken off.

Using these Clair Bros 15CX loudspeakers is easy. Just connect them to your audio system following the standard procedures. When setting up, make sure they are placed in a stable position for the best sound projection. For the speaker with the broken screw head on the back plate, be careful not to apply too much pressure on that area to avoid further damage. To maintain them, keep them clean by using a soft, dry cloth to wipe the exterior regularly. Don't expose them to extreme temperatures or moisture, as this can affect their performance. If you notice any other problems, it's best to consult a professional audio technician.
