The AD-P4T speaker of the company QSC is designed for installation in false ceilings or interior ceilings. The power of it is 30W RMS, which means it can be connected to an amplifier of similar power. However, you should also check the impedance of the speaker and the amplifier to ensure compatibility between them. 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).
