About Bluetooth® and aptX®
Our Bluetooth products easily connect to any of your devices that have Bluetooth, but to get the best sound possible we recommend using a device that supports Bluetooth aptX. Find out more about aptX here: csr.com/products/aptx

And if you’re looking for a new smartphone, tablet, or computer with aptX or want to look up your device and see if it supports aptX, go here to check out what’s available: aptx.com/products/browse/categories

And for iPad or iPhone users that don’t have aptX, don’t despair! MacOS (MacBook, iMac, Mac mini) include Bluetooth aptX, however if you use an iPhone or iPad, Apple generally uses the AAC codec and doesn’t support aptX. AAC sounds really good as well and you'll also get the extra benefit of our upsampling 24-bit DAC, so you won’t be disappointed by the sound quality if you use an iOS device with any of our Bluetooth products.

Custom components
Audioengine designs and manufactures our own speaker drivers and other critical components. In other words, the HD6 is not a “box-built" system with off-the-shelf parts, but includes custom-designed components constructed to our specifications. What we do not fabricate directly inside our factories we have made to our specific designs - parts such as circuit boards, transformers, magnets, and wiring harnesses, for example.
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.
Built-in B1 and D1
We’ve taken features from two of our best-selling products, the B1 aptX® Bluetooth® Receiver and the D1 24-bit DAC, and combined some of this circuitry with advanced speaker components to achieve a complete high-end analog and digital audio system.
High-quality Bluetooth audio
The Bluetooth built into the HD6 powered speakers features aptX coding which is an advanced Bluetooth audio codec with very impressive sound. And even if your phone or tablet doesn’t have aptX, the HD6 Bluetooth solution is backwards-compatible with SBC and AAC codecs, so you can wirelessly stream music from any Bluetooth-enabled device and still enjoy all your music. High-fidelity Bluetooth aptX that really works and sounds great. Here’s why:

Extended wireless range - 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 Bluetooth receiver and optical input both utilize the 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-bits, 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-bits - 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.
Furniture-grade finishes
The HD6 cabinets are available in several handsome finishes, including walnut and cherry veneers as well as satin black paint, offering a wide choice 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.
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 Kevlar woven glass aramid composite with rubber surrounds. Kevlar 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 "EI" transformers and also generate less heat.
