In this review, we will be comparing HD5 and HD6, two Powered Bookshelf speakers by Audioengine. Being Powered speakers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them.
Let's have a brief look at the main features
of Audioengine HD5 and Audioengine HD6 first before getting into our more
detailed comparison.

HD5 features a 0.75" Silk Soft-Dome Tweeter and 1 x 5" Aramid Woofer. On the other hand, the HD6 features a 1" Silk Soft-Dome Tweeter and 1 x 5.5" Kevlar Woofer.
Frequency Response
HD5 has a frequency range of 55-22k Hz whereas HD6 has a frequency range of 50-22k Hz. With a minimum frequency of 50Hz, the HD6 can go significantly deeper on the low side and provide stronger bass compared to the HD5's min frequency of 55Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Cabinet Type and Port Position
Both HD5 and HD6 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Audioengine HD5's and Audioengine HD6's external dimensions. Audioengine HD5 has external dimensions of 283.0 x 183.0 x 266.0mm (11.125inch x 7.1875inch x 10.4375inch) whereas Audioengine HD6 has external dimensions of 314.3 x 182.6 x 317.5mm (12.375 x 7.1875 x 12.5inch).
Audioengine HD5 is 31.3mm shorter and 51.5mm less deeper than Audioengine HD6 but it is also 0.40000000000001mm wider.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Audioengine HD5 is approximately 486.8cm2 / 75.5inch2 and base area of the Audioengine HD6 is approximately 579.8cm2 / 89.9inch2. The HD5 requires 16% less surface area than the HD6 which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Audioengine HD5 weighs 5.70kg / 12.5lbs and the Audioengine HD6 weighs 5.50kg / 12.1lbs. This makes the HD5 4% heavier than the HD6.
Here is a comparison of how HD5 and HD6's weights compare with the average, max and min weights in Powered Bookshelf class.

Siblings in Audioengine's HD series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | B | Audioengine HD6 digs deeper - 50Hz against 55Hz. A subwoofer would even that out. |
| Built-in power | evenly matched | Similar onboard amplification (100W vs 100W RMS). |
| Connections | evenly matched | The same set of inputs and streaming options. |
| Size | depends | Audioengine HD5 is easier to place; Audioengine HD6 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Audioengine HD5: a sub output; Audioengine HD6: a sub output. |
| Price | A | Audioengine HD5 is cheaper - $549 against $699, about 21% less. |
A Audioengine HD5 B Audioengine HD6
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Audioengine HD6 measures better, Audioengine HD5 costs about about 27% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 55Hz anyway, which makes the cheaper Audioengine HD5 much easier to justify.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
