These high-performance music speakers with integrated amplifier and Bluetooth feature a 2-way bass reflex speaker system with a 5.25" woofer and a silk dome tweeter. You can easily adjust the speaker volume using your smartphone, tablet, or any other Bluetooth-enabled device. The DS50 series is also equipped with a unique standby/auto power on system. It puts the amplifier into standby mode when no audio signal is detected for a certain period and turns it back on when you start playing music. Suitable for freestanding or wall mounting with the included adjustable mounting brackets. The trapezoidal design allows for clean installation in corners, making it ideal for background music, hi-fi, and surround sound applications. This active speaker offers a combination of speaker and integrated amplifier that are optimized for optimal sound reproduction. Issues such as tweeter overload due to strong distortion from bass signals or damage from mismatched or overloaded components are effectively prevented. Additionally, you no longer need an external power amplifier.
