Effortlessly fill any living space with the power of incredible, true stereo sound that brings your listening experience to life.
An all-access pass to ALL of your music on any app or device, the HD4 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.
The perfect tabletop or desktop speaker. The HD4 active powered Wireless Speakers are constructed with custom Audioengine components: Aramid fiber woofers, silk tweeters, Premium Bluetooth aptX-HD, and built-in analog power amps wrapped in precision-tuned, hand-built and finished wood-veneer cabinets. A perfect blend of cool retro looks with modern functionality.
No network to setup and all inputs are always ready to go. Connect a TV or turntable via the mini-jack or RCA inputs, use the onboard DAC and connect via USB to a computer, stream high res wireless with aptX HD Bluetooth, or just plug in headphones at your desk! The HD4 is an incredibly high performance, high value system for almost any application.
Audioengine speakers are special. Their built-in analog power amplifiers sound incredible compared to digital amps found in other mass-produced brands at comparable price points.
The HD4 wireless speakers offer versatile, high-fidelity audio ideal for smaller spaces. This is a premium-powered, two-speaker setup that offers excellent music reproduction and surrounds you with a sense of presence that most compact systems often miss. Bringing home the high-performance technology inside our HD6 along with the convenience of our modestly-sized HD3, the HD4 is a perfect blend of the power you love to feel and the modern functionality you depend on. Thoughtfully wrapped in precision-tuned, hand-built wood-veneer cabinets.
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.
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.
