Lb1-uw06-fx is an affordable 6 W universal speaker for indoor applications. The rear panel is equipped with two mounting brackets that can be easily and quickly mounted on walls or ceilings. The speakers are available in black or white. The sturdy MDF (medium density fiberboard) housing features a durable and easy-to-clean vinyl film for both white and black designs. The front panel is made of ABS material and is covered with a beautifully colored speaker cloth. All Bosch speakers are certified to meet IEC 268-5 power handling capacity (PHC) standards and can operate continuously for 100 hours at rated power. Bosch has also conducted simulated acoustic feedback exposure tests to ensure they can withstand twice the rated power in a short period of time. This ensures high reliability in extreme conditions, improves customer satisfaction, extends service life, and significantly reduces the chance of failure or performance degradation. Two mounting brackets are provided on the panel after installation/configuration in accordance with EN 60065 standard. Speakers can be easily and quickly installed on the wall or ceiling. If these supports are not needed, they can be removed, but three key holes in the back panel can still be installed on the wall. The rear panel is equipped with convenient and easy to use four-way pole push - in junction box, suitable for field connection. The junction box provides a power tap connection for the 100 V matching transformer in the sound column. This allows the user to select the rated full power, half power, or quarter power radiation (increase by 3 dB).
