The award-winning Audioengine A2+ Powered Speaker is a perfect example of the extension of this mission. With music streaming services and digital music players becoming the centre of the modern music system, consumers have had to accept a loss of the premium components resulting in the loss of sound quality. With a built-in digital-to-analog converter (DAC), the Audioengine 2+ allows you to send high-quality digital audio direct from your computer or other listening device's USB or AUX port. We've also added a variable RCA output to connect a subwoofer and you can even go wireless with the optional Audioengine B1 Bluetooth adapter. The Audioengine 2+ is a great introduction to high-quality audio and the perfect upgrade for your computer, turntable, TV, or favorite streaming device.
