Connect to your music no matter where it lives.

An all-access pass to ALL of your music on any app or device, the HD4 system offers wired or wireless connections including USB input from your computer, Bluetooth aptX-HD from your phone, or good old analog from that vintage turntable or prized tape deck.

Featuring Bluetooth aptX-HD for premium, extended-range wireless that allows for quick and easy connection to stream your existing music services, tune into your favourite podcast or listen to those carefully curated playlists from your personal music library.

Your music, your way. Anywhere you want to listen. It’s that simple.

Bold Design That Fits In

Versatile, size-defying sound.

Designed to take on space limitations, the HD4 is the perfect upgrade where surfaces are minimal but performance and convenience can’t be compromised. As handsome as they are compact, the HD4 will easily fit in any small living space and blend in with any decor.

Purpose-built for versatility, the HD4’s modest design does little to prepare listeners for such expansive soundstage and crystal-clear imaging. The difference between listening to your music and hearing ALL of it...with more room for dancing.

Extended Wireless Range

Most Bluetooth implementations have a very limited range, typically within just one room. But with careful signal management circuitry and antenna tuning, Audioengine offers a superior solution that has up to 3 times the range of standard Bluetooth for multi-room use, with no degradation in audio quality. Audioengine Bluetooth products have very low latency when compared to most Bluetooth receivers, around 30ms.

Unique, Bespoke Design

Audioengine's built-in analogue power amplifiers sound incredible compared to lower-cost digital amps found in mass-produced brands.

Audioengine designs and manufactures their own speaker drivers and other critical components. In other words, the HD4 is not a box-built system with off-the-shelf parts, but includes custom-designed components constructed to their specifications. What they do not fabricate directly inside their factories they have made to their specific designs. Parts such as circuit boards, transformers, magnets, and wiring harnesses, for example.

The speaker cabinets, drivers, innovative bass port designs, amplifiers, and passive crossovers are all critically tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires less power than passive speakers and a separate integrated amplifier or similar A/V components. Audioengine builds all this goodness into the left speaker cabinet to make it super-easy to connect your smartphone, tablet, computer, TV, network player or any other audio product.

Unlike most smaller computer speakers, Audioengine HD4 cabinets are constructed of 18mm-thick high-density fiberboard, rather than plastic. The HD4 system offers a whole new audio experience, guaranteed.

Amplifier & Driver Design

The amplifiers in powered Audioengine speakers are located in the left speaker and are a conservatively-rated class A/B analog monoblock design. This is a more traditional speaker/amplifier marriage which provides excellent quality audio and greater flexibility. All circuit boards for the power and preamp sections are vertically mounted for maximum mechanical shock protection.

Audioengine uses audiophile-quality, ferrofluid-cooled silk dome tweeters with neodymium magnets. Silk tweeters hold up well under high power and the edge-driven design gives very smooth response. The woofers are aramid fiber woven glass composite with rubber surrounds. Aramid fiber is obviously very strong, which means that the woofer retains its shape when being driven at high levels. The speaker materials and construction are robust enough to stand up to some serious thrashing, so speaker grills are not needed and they will sound and look great after many years of use.

About Audioengine

Audioengine has been changing the way people listen to music since 2005. We believe in the power of music and our passion is to inspire you to listen every day. Great sound, beautiful design and useful features.
