About the Audioengine HD6

Ralph Graves

Audioengine's flagship powered speakers

Audioengine HD6

Simple setup

The HD6 speaker system can be set up in minutes. Plug the left channel speaker speaker, which contains the system's amplification, into an AC outlet. Then run the provided connector cable to the right channel speaker. Then connect your sound sources.

The HD6 has optical digital input for TV sound. It also has an RCA stereo input for your turntable with built-in preamp or other audio component. A stereo minijack lets you connect virtually any portable device. Or you can go wireless with Bluetooth.

Bluetooth 5.0 with aptX-HD®

The HD6 uses aptX-HD, an advanced type of Bluetooth wireless streaming. It allows compatible devices to stream audio signals at near-CD quality. The system also works with earlier forms of Bluetooth. So you can play your music wirelessly from almost any portable device. You get an effective wireless range of up to 100 feet.

High-quality drivers and amplification

Each HD6 speaker features two custom drivers: a 1” silk dome tweeter for clear, accurate highs, and a 5-1/2” Kevlar woofer for clean, detailed midrange and solid bass. An RCA line-level output lets you connect a powered subwoofer — such as the Audioengine S8 — for even deeper lows. The left and right speakers are each driven by a 50-watt Class A/B monoblock amplifier, for sound that's clean, punchy, and immediate. The amps are supplied with steady current by a toroidal transformer for optimum performance.

Product Research


Two-Way Speaker Design: Each of the Audioengine HD6 speakers has two drivers; a 1" silk dome tweeter & a 5.5" Kevlar woofer. The HD6 provides a real, natural sound the way the artist intended. The HD6 has a frequency response of 50Hz to 22,000Hz (+/-1.5dB)

  • Silk Dome Tweeters: Audioengine uses audiophile-quality, ferro-fluid cooled silk dome tweeters with neodymium magnets. Silk tweeters hold up well under high power & the edge-driven design gives very smooth response.
  • Kevlar Woofers: The woofers are made of Kevlar woven glass aramid composite with rubber surrounds. Kevlar is very strong, which means that the woofer retains its shape when being driven at high levels. The woofers are housed in cast aluminum frames which provide high rigidity and increased heat dispersion.

Built-in Amplifier: The 50W x 2ch amplifier in the Audioengine HD6 is located in the left speaker and is 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. The built-in power amplifier saves space & eliminates the need to connect Audioengine HD6 to a stereo receiver or external power amp. Simply plug the left speaker into an AC outlet & connect the included 13' speaker wire from the left speaker's binding-post terminal to right speaker's binding post terminals. All internal components of the HD6 are tuned together, providing a more efficient system requiring less power than passive speakers & external amplifiers.

Bass Reflex MDF Cabinet: One of the reasons the Audioengine HD6 has such great bass response for a compact speaker is its slot-ported cabinet. Each cabinet features a rear-firing slot-port that has been specifically tuned for accurate bass down to 50Hz. The result is incredible low end with minimal audible air turbulence, so you can use the Audioengine HD6 speakers with or without a separate subwoofer. The cabinets are built using thick MDF with internal bracing. Internal sound-damping material reduces unwanted reflections inside the cabinet. The cabinet edges are rounded to reduce high-frequency diffraction effects on the front baffles. The speakers are hand finished, then tuned and tested together to be sold in matching pairs. Also included are detachable grilles that add further aesthetic advantages as they are firmly held in place with hidden neodymium magnets for a clean look.

24-Bit/192kHz DAC: The HD6 employs a 24-bit DAC that is widely known for its low-noise and high-fidelity. The optical input of the HD6 utilizes it as a bit-perfect 24-bit DAC, which will process sample rates up to 192kHz natively. For Bluetooth, it 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.

Bluetooth Music Streaming The Audioengine HD6 incorporates built-in Bluetooth 5.0 for wireless music streaming of stored music and music apps on your Bluetooth-enabled Apple iPod/iPhone/iPad, Android smartphone/tablet, Windows PC/Phone, Mac computer/laptop, and more to the powered speaker system. You will continue to control your music and view song/artist information from your Bluetooth-enabled device.

  • In addition to support for Bluetooth's standard SBC audio codec, the Audioengine speaker supports AAC for higher quality playback from Apple iOS devices, as well as support of aptX HD for 24-bit/48kHz audio playback from compatible devices. aptX HD supports 48kHz/24-bit LPCM audio over a Bluetooth wireless connection for a "better-than-CD" listening experience.
  • Upsampling DAC: Due to the high signal-to-noise specs of the HD6's DAC, 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 receiver presents impressive low noise and low distortion characteristics with a noticeable improvement over many other Bluetooth devices.
  • 100' Wireless Range: Most Bluetooth products have very limited range (only up to 30'), typically within just one room. But with careful signal management circuitry and antenna tuning, the HD6 offers a superior solution that has up to 3x the range (up to 100') of standard Bluetooth for multiroom use, with no degradation in audio quality.
Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Audioengine HD6.

Optical Digital Input: The Audioengine HD6 is fitted with a optical (toslink) digital input for connection of a digital audio device, like your Blu-ray player, gaming system, or TV. The optical digital input supports up to 24-bit/192 kHz PCM stereo.

Dual Aux Inputs: The HD6 is equipped with two analog Aux inputs. There is a stereo minijack (3.5mm) input and a stereo RCA input for connecting analog audio devices.

Variable Audio Output: The Audioengine HD6 includes a variable stereo preamp audio output so you can connect a powered subwoofer (such as the Audioengine S8; sold separately), other Audioengine powered speakers, or an Audioengine wireless adapter (772W3; sold separately) to daisy-chaining music to other systems around the house. This output is variable (adjustable) so the volume level can be controlled from the HD6 or remote control.

Simple Controls: The HD6 features a front-mounted volume control and a rear-mounted power on/off switch. It also comes with an IR remote for wireless operation of the powered speaker system. Remote control functions include Power on/off, Volume up/down, and Mute.

Toroidal Transformers: Power transformers are a large contributor to the overall audio performance, especially in the low end (bass response). Audioengine uses gapless core toroidal transformers which have a tighter radiated magnetic field, directly translating to lower noise. They are lighter than standard, lower-cost "EI" transformers and also generate less heat.

Placement: For the best soundstage & imaging, the speaker should be equidistant from the side walls & and a different distance from rear walls. Both speakers should also be equidistant from your primary listening position and at least 6' apart. Tweeters should be at approximately eye-level in your most frequent listening locations. For the best bass response, Audioengine recommend at least 6" of clearance between the rear of the speakers and the wall behind them.

Break-in Period: The speaker will sound great out of the box & will get better over time. No need to do anything else, but listen to them. Do give them at least 30-50 hours of break-in time before doing any critical listening.

When using bluetooth can i change volume by using phone or do i have to use remote control?
robert  Oct 08, 2022
1 answer
You may change the volume from your smartphone while connected via Bluetooth. Technically the volume control for the speakers is still active, so it would be ideal to set the speaker volume and smartphone volume in such a way that they work well together.
zachary  Oct 09, 2022 (Staff)
I am trying to add two speakers to my current set up. I currently have a Sony str-dn1080 receiver, Bic America F-12 powered subwoofer, Polk Audio FXI A6 Surround Speaker x 2, and a Polk Audio Signature Series S35 Center Channel Speaker. Can these speakers work with my current set up?
jencathen  Apr 30, 2020

These speakers can work with the receiver through its Zone 2 preamp output interface for playing audio in a different zone. They cannot work as part of the main theater speaker setup. We have advisors that you can reach by calling 1-800-324-9695 who can discuss your goals for the theater system to give a recommendation on speakers that can work.

Can I connect my Klipsch 10 in 300 w subwoofer so these speakers audio engine 6 because the way I have mine connected as one cable only because the speakers have a subwoofer Alpha it's only one single cable what do I have to get an adapter?
armando  Jul 28, 2019
1 answer
Hi Armando, thank you for your question. Since the AudioEngine 6 speakers have an active audio output, you can connect your Klipsch powered subwoofer. As long as your subwoofer has standard red and white RCA jacks, it will easily connect up to your speakers. Feel free to chat with an Advisor online or by phone at 1-800-324-9695.

thomas  Aug 03, 2021 (Staff)
I have two separate built-in bookshelves on either side of a doorway. I'd like to put a speaker in each built-in. Do the speakers have to be connected to each other? If so, this set-up obviously won't work.
caitlin  Nov 24, 2020

Yes they do. Only one of the two speakers connects to an outlet and a speaker wire must run from that speaker to the other one.
michael  Nov 25, 2020
The speakers have to be connected . A 12 foot speaker wire is included
gary  Nov 25, 2020
Yes. The powered left speaker must be plugged into an electrical outlet and wired to the right speaker.
robert  Nov 25, 2020
