The NCSS5 speaker of the company Power Dynamics is designed for installation in false ceilings or interior ceilings. The power and impedance of it is 20W RMS and 8Ω respectively, which means it can be connected to an amplifier with the corresponding characteristics. This is a 2-way speaker, meaning the sound frequencies are reproduced by two speakers, a tweeter for the highs and a woofer for the lows. A high-quality ceiling speaker can provide uniform coverage and satisfactory frequency response, so it can be used for speech reinforcement or for low-intensity music applications (background music).
