Rio42, Rio62, Rio82 are high-performance ceiling speakers designed for fixed installation applications. Its white frame (color can be customized according to customer needs) can be easily integrated with many installation environments, such as: hotels, shopping centers, discrete requirements Various venues for sound reinforcement. Rio42, Rio62, Rio82 use two-way design to ensure that the best performance can be maintained in important mid-frequency segments. The rear cover is made of metal, which has a solid structure and can ensure an extended low frequency response even when the sound pressure level is uneven. The metal back cover also increases the fire protection level and improves the safety level. The coaxially mounted high-frequency driver provides a very consistent time domain response, and a special synthetic rubber is used around the driver to ensure high definition and smooth frequency response. The integrated transformer can be used for high impedance line connection operation, simplifying system wiring. The transformer is a high-quality insulated E.I core design, which can perfectly match the 16Ω woofer and tweeter. The front power switch can be easily adjusted after the speaker is installed. All plastics inside the loudspeaker are UL-94V-0 grade, ensuring stable and reliable system installation. The speaker installation is very simple and can be firmly fixed on the ceiling with only a few screws.
