The Audioengine HD Series was designed for the way people listen to music today, and HD3 raises the bar and sets a new standard for compact mini music systems. HD3 fits just about anywhere you listen and was designed to play all your music from any device. Easy setup, simple but useful features, and real stereo sound make HD3 the go-to system for all your music.

Today’s music is available from many different sources including computers, tablets, smartphones, and turntables. HD3 is designed with multiple inputs to accommodate all of these digital and analog sources. HD3’s Bluetooth receiver, which supports aptX and AAC codecs, has a range of about 100 feet so you can stream all your music from almost anywhere in your house. Its USB input bypasses your computer’s lower-quality DAC for a high-fidelity listening experience. Lastly, dual analog inputs round out the HD3’s impressive suite of connections.

HD3 cabinets are available in several handsome finishes, including walnut and cherry veneers, as well as satin black paint, offering a wide choice for complementing room furnishings. Also included are detachable grilles that add further aesthetic advantages as they are firmly held in place with hidden neodymium magnets for a clean look.

“Classic speaker design with no plastic, full stereo sound, whole-house wireless and no setup hassles make HD3 the ultimate mini music system.” Brady Bargenquast, Audioengine co-founder.
