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 A2+ Wireless's and Audioengine A1-MR's external dimensions. Audioengine A2+ Wireless has external dimensions of 158.8 x 106.4 x 168.3mm (6.25 x 4.1875 x 6.625inch) whereas Audioengine A1-MR has external dimensions of 158.8 x 106.4 x 181.0mm (6.25 x 4.1875 x 7.125inch).
Audioengine A2+ Wireless has the same height and width with Audioengine A1-MR. On the other hand, with a thickness of 168.3mm, it is 12.7mm less deeper.
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 A2+ Wireless is approximately 179.1cm2 / 27.8inch2 and base area of the Audioengine A1-MR is approximately 192.6cm2 / 29.9inch2. The A2+ Wireless requires 7% less surface area than the A1-MR 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 A2+ Wireless weighs 1.40kg / 3.1lbs and the Audioengine A1-MR weighs 1.10kg / 2.4lbs. This makes the A2+ Wireless 27% heavier than the A1-MR.

Siblings in Audioengine's A series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (65Hz vs 65Hz). |
| Built-in power | evenly matched | Similar onboard amplification (30W vs 30W RMS). |
| Connections | B | Audioengine A1-MR adds Wi-Fi and streaming. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Audioengine A2+ Wireless: a sub output; Audioengine A1-MR: a sub output. |
| Price | B | Audioengine A1-MR is cheaper - $229 against $269, about 15% less. |
A Audioengine A2+ Wireless B Audioengine A1-MR
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?
Audioengine A1-MR has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does.
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.
