MATERIALS AND CONSTRUCTION

0.7″ (18 mm) thick MDF cabinets with real wood veneer
1″ (26 mm) silk dome tweeters with neodymium magnets
5.5″ (140 mm) aramid fiber woofers with advanced voice coils

CABINETS

To minimize unwanted resonances and distortion, Audioengine cabinets have thick high-resin MDF walls with extensive internal bracing. Heavy internal sound-damping material is used to reduce unwanted sound reflections inside the cabinet. All cabinet edges are rounded which look great and reduce high-frequency diffraction effects on the front baffles. The HD6 cabinet contains tuned, rear-port slots.

FURNITURE GRADE FINISHES

HD6 cabinets are available in several handsome finishes, including walnut and cherry veneers as well as satin black and high-gloss white paint, offering a myriad of options for complementing room furnishings. Also included are detachable grills that add further aesthetic advantages as they are firmly held in place with hidden neodymium magnets for a clean look.

CUSTOM COMPONENTS

Audioengine designs and manufactures our own tweeters, woofers, and other critical components. In other words, these are not “box built” speakers with off-the-shelf parts but custom-designed to our specifications. What we do not fabricate directly in our factory we have made to our designs (parts such as transformers, magnets, and wiring harnesses, for example). The cabinets, drivers, bass port designs, amplifiers, and crossovers are all painstakingly tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires much less power than passive speakers and a separate integrated amplifier or similar A/V components.

BASED ON STUDIO MONITOR DESIGNS

Studio monitor speakers are used by producers and engineers in recording and production studios. They are designed with a theoretical flat frequency response which allows the engineer to create a final mix in such a way that the recorded music will sound good on most other speakers. Although Audioengine speakers are not designed to be up-close “nearfield” studio monitors, we do carry over much of the same higher-end technology, components, and design philosophy for all Audioengine speaker systems.

EFFICIENT INTEGRATED DESIGN

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. We build 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.

HIGH-QUALITY BLUETOOTH AUDIO

The Bluetooth built into the HD6 powered speakers features aptX HD coding which is an advanced Bluetooth audio codec with very impressive sound. And even if your phone or tablet does not have aptX HD, the HD6 Bluetooth solution is backwards-compatible with SBC and AAC codecs, as well as standard aptX, so you can wirelessly stream music from any Bluetooth-enabled device and still enjoy all your music. High-fidelity Bluetooth aptX HD that really works and sounds great. Here is why:

Extended-range wireless.
Most Bluetooth implementations have very limited range, typically within just one room. But with careful signal management circuitry and antenna tuning, we offer a superior solution that has up to 3 times the range of standard Bluetooth for multi-room use, with no degradation in audio quality.

24 bit DAC
The HD6 include an AKM AK4396A DAC, widely known for its low-noise and high-fidelity. The optical input configures the AK4396A as a bit-perfect 24 bit DAC, which will process sample rates up to 192kHz natively. But for Bluetooth the AK4396A is used as an upsampling DAC and will pad all bit depths to 24 bit, achieving a higher signal-to-noise ratio and lower noise floor. Due to the high signal-to-noise specs of the AK4396A, the fact that digital signal is upsampled to 24 bit as well as the added benefit of onboard triple redundancy power source conversion and filtering, the HD6 Bluetooth implementation presents impressive low noise and low distortion characteristics with a noticeable improvement over other Bluetooth devices.

AMPLIFIER 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.

DRIVER DESIGNS

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 the woofer retains its shape when being driven at high levels. The HD6 woofers are housed in cast aluminum frames which provide high rigidity and increased heat dispersion.

POWER TRANSFORMERS

Power transformers are critical to to high-quality audio performance, especially in the low-end and again, no off-the-shelf parts. Audioengine uses gapless core toroidal transformers which have a tighter radiated magnetic field, translating to lower noise. They are lighter than standard, lower-cost transformers and also generate less heat.

SHIELDING

Both drivers are directly video shielded and allow the user to place the speakers within a few inches of a video monitor. This shielding also offers protection for hard-drive digital music players.
