The Ultimate Personal Music System

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.

Versatile connectivity

In the spirit of the HD Series, we’ve included features from some of our best-selling products making HD3 an incredibly versatile speaker system. Stream TIDAL, Spotify, Pandora, YouTube - or any other streaming service or media player - wirelessly from your smartphone, tablet or computer. You can also connect your favorite turntable and even connect a subwoofer, so no matter how you listen to music, HD3 has you covered.

All Your Music, Day & Night

HD3 includes a headphone output and volume control on the front panel so you can listen to your favorite headphones without disturbing the neighbors or significant other. HD3’s built in headphone amplifier delivers a high-end sound that is a perfect match with even the most-demanding headphones.

Retro-Forward Design

HD3 was designed first for audio performance, but speakers also need to look great, right? The furniture-grade wood veneers, aluminum trim accents, and detachable magnetic grills give the HD3 a look and feel of old-school elegance that blends with any decor. Available in Satin Black for your stealth system as well as Walnut and Cherry wood finishes at no additional cost if you want to really show them off.

Small Speakers That Pack a Punch

Built-in power amplifiers save space and eliminate the need to connect HD3 to a stereo receiver or external power amp. Simply plug the left speaker into a power outlet and connect the included speaker wire from the left to the right passive speaker. All internal components of the HD3 are designed and tuned together, so you’ll get Audioengine’s Signature Sound and a much more efficient system than traditional separate passive speakers and amplifiers.
