Audioengine HD6 vs A5+ feature comparison

Let’s take a closer look at the features the Audioengine HD6 and A5+ offer

Audioengine HD6

If you are interested in bookshelf speakers under $1000, Audioengine HD6 may be one of the most obvious options. The brand is known for emphasizing functionality over design, but their HD6 model is both stylish and capable of producing high-fidelity audio.

Audioengine HD6

Unlike most of Audioengine’s speakers, the HD6 will actually fit most living room spaces without drawing too much attention, as their vintage design allows them to blend in seamlessly into different spaces.

These speakers are more powerful than Audioengine’s models like the HD3 or HD4, although their visual appearance is almost identical.

You can use the HD6 model as computer speakers, but their wireless connection and sound playback abilities enable you to use them with Smart TVs to watch movies or any other type of content that requires excellent audio quality.

Key features

  • 150W peak power total (50W RMS and 75W peak per channel)
  • Variable line-out with 2V RMS and 47ohm output impedance
  • Bluetooth 5.0 receiver
  •  AKM AK4396 internal D/A converter
  • 100ft wireless operation range
  • Analog dual-class A/B monolithic amplifier
  • 14W power consumption in sleep mode

Overall design

The first thing that catches the eye when you take a look at the Audioengine’s HD6 speakers is their vintage design that resembles the speakers from the 1960s and 1970s.

The speaker cabinet is made from high-quality wood that is available in Satin Black, Walnut, Cherry Wood, and Hi-Gloss White finishes. The manufacturer also included the front grills that are equipped with magnetic attachments, which enables you to remove them if you prefer a more conventional look.

The HD6 speakers are self-powered, and there is no need to connect them to an amplifier since they come with a 150W amp that supplies 75W to each channel. However, the built-in amp increases the weight of the left speaker that weighs 17.5lbs.

Also, these speakers feature a heat sink that helps disperse the heat that is generated by the amp and prevents the electronics from overheating.

Although they are slightly larger than standard desktop speakers, the HD6 can be used to play music from a computer or a smart TV with the same level of efficiency.

Playback capabilities

You can find a 3.5mm stereo mini-jack, optical input, stereo RCA inputs and outputs, and the output for the passive right speaker, on the back of the left Audioengine’s speaker. The front of the left speaker features a Volume control knob, a power indicator, and a remote receiver.

Moreover, the AC power outlet, the power button, and the voltage selection switch, as well as the Bluetooth antenna can all be found at the back of the left speaker.

If you’re planning on using the optical input you will have to purchase a TOSLINK Plug to Plug adapter as it is not one of the accessories that come with HD6 speakers.

The Bluetooth antenna has a 100ft radius which enables you to connect these speakers to smart devices or computers even if they are not easily approachable.

The connection type doesn’t really affect the quality of the sound these speakers produce, as even heavy-bass tracks sound terrific when played on the HD6 speakers. Besides these speakers are loud enough to be used in medium-sized and larger rooms.

Check out our guide through the best speakers for small rooms, if the volume level of the HD6 speakers exceeds your expectations.

Other noteworthy features

These speakers come with a number of accessories that make everyday use easier. If you decide to purchase the Audioengine HD6 speakers you will get a pair of microfiber bags that provide you with a simple storage solution, 6.5ft. RCA and mini-jack audio cables, 12.3ft of speaker wire.

The setup process is straightforward, and it shouldn’t take more than a couple of minutes, but if at any point you need assistance, you can use the setup guide that comes with the HD6 model. A remote controller is also among the accessories that are bundled with these Audioengine’s speakers.

However, the controller only has basic options that allow you to control the volume level, mute the speakers, or put them into sleep mode. There are no Play, Pause, or Skip options, so you can’t use the remote to change a song or control your playlist in any way.


The manufacturer claims that HD6 speakers need between 50 and 60 hours of playing time to achieve their optimum performance, which indicates their durability. Although the bass playback of these speakers is seamless, you should consider pairing them with a subwoofer to get an even fuller sound.

The Audioengine HD6 speakers come with a three-year warranty that covers most defects of their components.

A long warranty period is an indicator of how reliable these speakers are, as they are built to meet the expectations of music fans who like to turn the volume up while listening to their favorite artists.

Audioengine A5+

The A5+ speakers were released almost ten years ago, and a decade later, they are still among the best computer speakers on the market. Needless to say, their audio playback capabilities are truly remarkable, especially when you consider their size.

Audioengine A5+

Although they may not be the most visually appealing pair of speakers you can lay your eyes on, the A5+ speakers are still functionally designed to fit any desktop computer configuration.

You can use this Audioengine’s model as TV speakers, but they won’t shine in this role unless you connect them to a subwoofer. The A5+ speakers are an upgraded version of the Audioengine’s A2+ speakers that have considerably lower power output capacity.

Like all other Audioengine’s models, the A5+ speakers are self-powered, and there is no need to connect them to an external amp. Also, you can choose the voltage at which the speakers are going to operate, and they come with a replaceable fuse that makes them more durable.

Key features

  • ½-inch thick MDF cabinets
  • 150W peak power or 75W per channel
  • USB and RCA variable line-out outputs
  • 5-inch aramid fiber woofers with advanced voice coils
  • 3.5 mini-jack and RCA L/R inputs
  • Dual-class AB monolithic amplifier
  • -50dB crosstalk

Overall design

Like all Audionegine’s models, the A5+ speakers contain custom-made parts, and their cabinets, bass port, and drivers are built to work together to generate impeccable sound. Despite having the same maximum power output capacity as the HD6 model, the A5+ can’t achieve the same volume levels.

This can largely be contributed to 5-inch aramid fiber woofers and ¾-inch silk dome tweeters that use the available power less efficiently.

The ½-inch thick MDF cabinets are available in Satin Black, Hi-Gloss White, and Natural Bamboo finishes, but keep in mind that models with Natural Bamboo finish cost extra.

The visual appearance of A5+ speakers is somewhat generic as they don’t look much different from most computer speakers. The removable speaker covers are not available for this model as the manufacturer doesn’t include front grills in the offer.

However, they are lighter than the HD6 speakers, as the left speaker of the A5+ model weighs 15.4lbs while the weight of the right speaker is 9.6lbs. These speakers are also smaller than the HD6 speakers which makes it easier to carry them with you.

Playback capabilities 

The front of the left speaker features the Volume Control knob, and power and remote receiver indicators. The conventional 3.5mm stereo mini-jack, the output to the right passive speaker, and Stereo RCA inputs and outputs are located at the backside of the left speaker.

The lower end of the rear panel houses the Power and Voltage switches, a replaceable fuse, and the AC power inlet. It is also worth noting that the A5+ has a USB port you can use to charge Smartphones or similar devices, but you can’t transfer audio data through it.

The gapless core toroidal transformers generate a tight magnetic field that reduces the noise and improves the quality of sound these speakers produce. The A5+ speakers can play any genre of music without distorting the sound, but the clarity of the audio varies from song to song.

audioengine a5+ brown

Even though this Audioengine’s model may struggle to produce clear sound at all times, it is still the most powerful pair of speakers in its price range.

Other noteworthy features

The list of accessories that come with the A5+ speakers is not impressive, since you will only get a detachable power cord, a 6.5ft mini-jack, and 6.5ft RCA to RCA cables.

The remote control is both durable and elegantly designed, but chances are that you won’t find much use for it, as it only allows you to control the volume level. The setup process is intuitive, and you’ll also get a setup guide that’ll provide detailed instructions for each step of the process.

Getting a subwoofer like the Audioengine’s S8 model may help you improve the quality of sound A5+ speakers generates, but it will nearly double their price. Moreover, you cannot upgrade these speakers to support any of the wireless connection features offered by the Audioengine HD6 model.


The components of the A5+ speakers meet the highest industry standards, and you can use these speakers for years without having to worry about replacing them.

Like all other Audioengine’s products, the A5+ model is covered by a 3-year warranty so in case any of the components breaks down during that period, you will be able to replace it.

You shouldn’t expect excellent performance at high volume as A5+ speakers are designed for playback of the media that is commonly played on computers. Read our full Audioengine A5+ review to get more detailed information about these speakers
