Different kinds of product: one is active with its amplifier built in, the other passive and needs one. Judge them on how you want to own the system, not just the specs.
| Area | Better | Why |
|---|
| Bass | B | Audioengine A2+ Wireless digs deeper - 65Hz against 95Hz. |
| What you buy | depends | Audioengine A2+ Wireless is a complete system - just add a source. Q Acoustics 7000LRi also needs an amplifier: more money and another box, but you choose it. |
| Connections | depends | Audioengine A2+ Wireless has Bluetooth built in. With Q Acoustics 7000LRi that all comes from the amplifier you pair it with. |
| Upgrade path | depends | Q Acoustics 7000LRi can be re-amped later and outlive several amplifiers; Audioengine A2+ Wireless ages as one unit. |
| Size | depends | Audioengine A2+ Wireless is easier to place; Q Acoustics 7000LRi is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Sealed vs Ported. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability | B | Audioengine A2+ Wireless: a sub output. Audioengine A2+ Wireless sits in a wider range (7 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($269 vs $269 a pair) - though the passive pair still needs an amplifier. |
A Q Acoustics 7000LRi B Audioengine A2+ Wireless
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 A2+ Wireless suits you if you want one box, ready to play, with nothing else to buy. Q Acoustics 7000LRi suits you if you already have an amplifier, want to choose the electronics, or expect to upgrade in stages. Neither is the better speaker in the abstract. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 95Hz anyway, so judge these on the other rows instead.
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.
