Audioengine HD6 Premium Powered Speakers, 1 pair, with stereo analog, digital and Bluetooth® aptX® inputs.
Audioengine HD6 Premium Powered Speakers
Our flagship HD6 powered speaker system represents a major milestone for Audioengine and shows just how far we’ve come in 10 years. Featuring built-in amplifiers that really pack a punch as well as analog and digital inputs including aptX® Bluetooth® and optical, the HD6 is not just another great-sounding pair of Audioengine powered speakers, but a complete audio system. Easy to set up, simple to use, and designed for the way people listen to music today.
We’ve included features from some of our best-selling products making HD6 quite possibly the most versatile powered speaker available. Stream TIDAL, Spotify, Pandora, YouTube - or any streaming service or media player - wirelessly from your smartphone, tablet or computer. For the highest resolution connect to the optical input, which is perfect for network music players. It can also be used to connect any component with an optical output, including your TV system. You can also connect your favorite turntable or a subwoofer, so no matter how you connect and listen, HD6 has you covered.
The HD6 was designed first for performance, but speakers also need to look great, right? The furniture-grade wood veneers and detachable magnetic grills give the HD6 a look and feel of old-school elegance that blends with any decor. Available in Satin Black for your stealth system as well as Walnut and Cherry wood finishes at no additional cost if you want to really show them off.
Built-in power amplifiers save space and eliminate the need to connect HD6 to a stereo receiver or external power amp. Simply plug the left speaker into a power outlet and connect the included speaker wire from the left to the right passive speaker. All internal components of the HD6 are designed and tuned together, so you’ll get Audioengine’s Signature Sound and a much more efficient system than traditional separate passive speakers and amplifiers.
The HD6 is Audioengine’s latest statement on high-quality and highly-affordable audio. The all-new woofers have diecast aluminum frames allowing the lower-end to really perform. Also new are the silk dome tweeters which have been upgraded for even smoother, more extended highs, superior stereo separation, and incredible imaging. The HD6 speaker cabinets are also a new design that are thicker and more stable which reduces unwanted resonances.

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.

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.
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.
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 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 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.
Why is the HD6 Audioengine’s best speaker yet?
- larger redesigned woofer with die-cast aluminum frame for extended bass response with fast dynamics
- new larger custom 1” tweeter for an open and realistic high end and an extraordinary soundstage
- thicker, low-resonance cabinet
- upgraded crossover components
- Bluetooth aptX and digital optical inputs
- real wood-veneer cabinet finish options
- removable magnetic grills
- solid aluminum remote control
Just how easy is it to set up Audioengine powered speakers?
Unpack and place them where you want and plug in the AC cord. Connect the included speaker wire from the active speaker to the right passive speaker. Then plug in your music (iPod, CD player, computer, etc.) with the supplied cables and you're ready to go. Our powered speakers are an all-in-one solution with no extra amps or components needed!
When I connect a turntable to my HD6, why is the volume is extremely low?
Some turntables may not have a built-in preamp and you would need to add an external phono preamp to bring the instrument level signal of the turntable to line-level. Some turntables may have a built-in preamp but have a switch on the back for either "line" or "phono," such as the Music Hall USB-1 or the Audio Technica AT-LP120; the switch would need to be selected to "line" in order to work directly with the speakers.
Should I use the volume control on the HD6 or can I adjust from system volume on my computer?
If the left speaker ends up in an easy to reach location, you can certainly use the physical knob to set volume. If not though, we generally recommend setting the HD6 at around 50% and adjusting from source.
Why do I have to plug one speaker into the wall?
Audioengine powered speaker models have a built-in power amplifier in the left speaker so you won’t need a stereo receiver or other extra components for power.
What is the difference between powered and active speakers?
Both are basically the same. “Active” and “powered” speakers refer to speakers with power amplifiers built into either one speaker or both. Audioengine speakers were designed with the power amps in the left speaker to make connections easier as they only require 1 power cord and all connections are on the same speaker. It’s time to sell that big old stereo receiver and make the switch!
Will I get buzz from the speakers if I place my iPhone near my Audioengine speakers? I don't see any mention of GSM shielding in the speakers in the setup guide.
All Audioengine speakers are video and magnetically shielded. GSM buzz however cannot be blocked by magnetic shielding. What actually causes "GSM buzz" is the phone being in 2G or "EDGE" instead of 3G. For best results when using your iPhone as a music source, ensure that it's operating on 3G by going to "Settings/General/Network/Enable 3G". If using 3G instead of 2G or "EDGE" is not possible in your service area, your best bet would be to keep it in airplane mode.
It is true that speaker placement really can make a difference in sound quality?
There are different theories but rooms and tastes are different so it's tough to specify a correct placement. We suggest you experiment with different locations to see what works for you. As a general rule of thumb for the best sound stage balance, the speakers should be equi-distant from side walls and a different distance from rear walls. For the best bass response on rear-ported speakers (like Audioengine 5+), we recommend that you keep a minimum distance of 6-12" between the rear of the speakers and the rear wall. Our front-ported speakers (such as the Audioengine 2+ or P4) do not need any rear panel clearance for better bass but recommend keeping them a few inches from the rear wall for adequate ventilation.
Will the sound be affected if I place the left (active) speaker on the right side and the right speaker on the left?
Swapping sides will not have any negative effect on the soundstage or quality/clarity of the speakers. This will simply give you the reverse of what the artist intended for you to hear.
Can I increase the length or change the speaker wire between each speaker?
Sure. For the best audio performance we’ve included 6.5 feet of 16 gauge wire with each powered speaker system but any "stranded" speaker wire will work. The speaker binding posts on the back of each cabinet will accept bare stranded wire, however you can also use wires terminated with spade lugs, banana plugs, or pins.
Is it OK to connect Audioengine active speakers to my stereo receiver or integrated amplifier?
We’ve built amplifiers into our powered speakers but if you wish to use Audioengine speakers with an existing receiver take the “preamp out” from your receiver and connect it to one of the Audioengine inputs (if you need to, use the included RCA stereo “Y” connector to 1/8” mini plug cable). We also make a pair of passive speakers called P4 so check those out as well!
Do higher power output ratings for audio gear mean louder or better sounding speakers?
Not necessarily. Audioengine speakers and amplifiers are very efficient and designed together as a system so therefore we get more volume output than stereo receivers or amplifiers that might higher wattage or power numbers. Due to this tuning we achieve big sound outputs with a fraction of the power required by other systems.
Are two separate speakers really better than one boombox or soundbar?
We are firm believers that two quality speakers will always sound better than one or more speakers together in a single cabinet, regardless of the amplifier or sound enhancing technology used. There are some decent one-piece speaker systems that simulate stereo and surround sound from a single source, but most fall way short as they can’t accurately duplicate a wide sound stage with imaging as complete and rich as Audioengine speakers.
Can I use a subwoofer with Audioengine powered speakers?
Even though Audioengine speakers have big and tight low end which will easily fill a room and rival floor standing speakers many times their size, you can also connect an external sub if you wish (or connect Audioengine speakers to your sub's line-level output). You can even connect our wireless W3 adapter for a wireless subwoofer!
Why do digital music files sound better with Audioengine speakers?
Audioengine speakers were specially designed and tuned to make MP3 and other digital music files sound great. We spent many months tuning each speaker and almost exclusively used various compresses and lossless files types encoded at different bitrates during this process. Even though we are big fans of digital music your turntable or reel-to-reel tape player will sound equally as good.
Can I control Audioengine speakers with my TV remote control?
Although many TVs have only one L/R audio output, which typically defaults to fixed, this setting can be sometimes be changed via the on-screen menu so please check your manual to see which outputs are variable. Also try the headphone output.
If I have 2 inputs plugged in at the same time, how does Audioengine switch between audio sources?
Both inputs are "open" or active, so you can leave 2 audio sources plugged in at the same time with no need to flip any switches!
Are these speakers designed for use only with computers or iPods? I would like to connect them to my Panasonic DVD player or TV or even my Denon stereo. Is this possible?
Yes, absolutely. All your A/V gear with an RCA or mini-jack 1/8" connector (even a headphone jack!) will work great with Audioengine powered speakers.
If I have a subwoofer of my own, how would I use it with the HD6?
Connect the variable output of the HD6 into the input of your sub using RCA cables. Very simple.
What if my TV only has one audio output that cannot be controlled with the TV remote?
Although many TVs have only one L/R audio output, which typically defaults to fixed, this setting can be sometimes be changed via the on-screen menu. Also try your TV's headphone output or the audio outputs from your satellite or cable box.
What if my speakers or subwoofer have a hum or buzzing sound?
Hum or buzz in the speakers is usually caused by something external to the speakers which is coupling noise into the speaker system, either through the AC lines, cordless phone, wireless router, or directly from the source input. A common reason is that the entire system is set up such that a "ground loop" results. Basically, a ground loop occurs when the AC power grounds and the system signal grounds are not at the same electrical potential. Refer to our online Setup Guides for a list of things to try.
What is the AC power cable type for Audioengine powered speakers?
We use non-polarized 2-Pin IEC 320-C7 cables. These are fairly standard cables, and you should be able to find them locally if needed. You can also find them in the Accessories section in our store.
Adding a new component could bring out hum or buzz that may not have existed before. Your first assumption could be that something may be wrong with your new gear but this is generally caused by a “ground-loop” in your system. Consider these tips for possible solutions - Click Here.
