The l30bc 95/15 is a suspended spherical speaker that can be suspended from the ceiling by connecting cables. The stylish shape and natural color make this suspended spherical speaker with distinctive structural features. The basic function of the suspended spherical loudspeaker is to prevent liquid from splashing in, which is very suitable for outdoor applications and high humidity environment, such as swimming pool. They have an excellent range of sound transmission and are therefore ideal for high-ceilinged buildings such as shopping malls and stores. The speaker housing is made of beige white high strength ABS flame retardant material (in accordance with UL 94 V0 standard). In addition, speakers can also be hoisted using color-matching connecting cables (which can be conveniently shortened to the required height). The speakers are attached with cable clips and ceiling caps. We do not recommend the use of these speakers in windy conditions. 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 of the speaker under extreme conditions, improves customer satisfaction, extends service life, and significantly reduces the probability of failure or performance degradation. All plastic parts are made of high strength ABS flame retardant material (in accordance with UL 94V0 standard). Like all Bosch products, they are carefully designed to ensure strict safety standards are met. These speakers meet all safety and installation requirements in the EN 60065 standard. Waterproof conform to EN 60529 and IP 63 standard certification European CE installation/configuration all device attached color four core connecting cable, and each color of cable core even pick up to 100 V different joint matching transformer. This allows the user to choose between a full radiation rating, a semi-radiant power, or a quarter of a radiant power (increment 3 dB). Dimensions (mm)
