The EdgeMax EM90 speaker of the company Bose is designed for installation in false ceilings or interior ceilings. The impedance of it is 8Ω, which means it can be connected to an amplifier of similar impedance. However, you should also check the power 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).
