The Echo Studio is a premium, yet compact and affordable smart speaker. It has a 5.25" woofer, a 1" tweeter and three 2" midrange drivers. It also has a 330W amplifier and a 24-bit DAC. That setup, together with Dolby Atmos and Sony's 360 Reality Audio technology, allows this small device to provide 3D audio. It even has built-in microphones that sense the acoustics of its surroundings, which it uses to automatically calibrate its sound for the best experience. All that, plus Alexa's benefits - voice control, smart home control, and virtual assistant - makes this speaker one to watch out for.
