The Edifier R990BT bookshelf speakers are designed to deliver high-quality audio performance with a combination of advanced features. Each speaker cabinet contains a 1" silk dome tweeter and a 4" long-throw mid-low driver, ensuring clear and accurate sound reproduction while minimizing resonance and distortion thanks to the MDF cabinet construction.

Equipped with a digital amplifier capable of delivering 15W to each speaker, these bookshelf speakers offer a total output power of 24W (RMS), making them suitable for filling medium-sized rooms with rich, immersive sound. The dynamic range control (DRC) feature further enhances the audio experience by optimizing the sound output.

Additionally, the speakers feature dual RCA input ports to simultaneous connect two devices via audio cables, providing flexibility in connectivity options.
