The Perfect Harmony of Modern Design and Dynamic Sound

Designed for smaller spaces, the Audioengine HD4 provides rich and vibrant audio reproduction that smaller systems often lack. The HD4 combines the power of the larger HD6 with the convenience of the smaller HD3. The system is housed in hand-built, real-wood-veneer cabinets for a modern and stylish look. You could call the HD4 eye and ear candy.

Everything You Want in a Music System, Without the Cords

The HD4 gives you the choice of connecting via USB, analog, or Bluetooth aptX-HD from your phone, tablet or computer. Bluetooth aptX-HD gives you CD-like quality sound and extended-range wireless that connects quickly and easily. Enjoy all of your music services, tune into your favorite podcast, or listen to anything and everything from your personal music library.

The HD4 Leaves You Plenty of Room to Groove

Good news! You don’t have to sacrifice sound quality when you’ve got limited space. Designed to take on space limitations, the HD4 is the perfect choice when your surface area is minimal and exceptional performance is a priority. As stylish as they are compact, the HD4 will easily fit in any small space and fit in with any style of decor. But the HD4 is more than just a pretty face. This system provides brilliant highs and thumping lows. It’s the difference between listening to your music and experiencing it.
