Essence For High Res Audio - because music is the essence of life Ketan Bharadia, What Hi-Fi August 2025 · reviewer · Jul 2025

“These Acoustic Energy AE300 Mk2 are up against some tough competition, but we feel their controlled and detailed presentation serves them well. They don’t try to bite off more than they can chew, and in the process deliver a superbly judged sound that works well across musical genres and with a wide range of electronics.

When listened to against their key rivals, the Acoustic Energy are smoother, more refined than almost anything else at this level, with, to quote from our review, "high-frequency sounds shimmer rather than sizzle". The AE300 Mk2 aren't the sort of speakers that immediately grab your attention. Instead, they steadily charm you, revealing themselves to be a superb pair that, if you invest some time, will reward you endlessly.

Acoustic Energy AE300 Mark II. The best speaker here doesn't demand your attention. It earns it slowly, confidently, completely.

:) A few yers ago I had the pleasure to listen to the AE300's at the Bristol Hifi show and they were absolutely excellent. The demo track was an energetic (no pun intended) acoustic guitar sample and the texture and tone, as well as the scale of the image was really impressive. They were using an AVI Labratory Series S21 M1 amplifier.

And this model, to me, also has a bit of that dark color, it's not that sharp bright sound that you get from Kevlar, or, you know, from high-definition dome tweeters. They are incredibly smooth, right? Very smooth

Happily, we have a new entry in the shape of the Acoustic Energy AE300 Mk2 . We haven't had Acoustic Energy speakers in our test rooms for quite some time, but the AE300 have made such an impression that they've ousted the Bowers & Wilkins 607 S3 – multiple What Hi-Fi? Award winners and longstanding favourites – as our pick as the best mid-priced standmounts.

According to What Hi-Fi, the Acoustic Energy AE300 Mk2 edges out the long-standing favourite. They’re smoother, more refined, and more versatile in real-world systems — all while matching the build quality of the Bowers & Wilkins 606 S3 .

On top of that, based on our experience covering the speaker market since the 1970s, products in the AE300 Mk2's class don’t tend to go on deal often. Smaller companies don’t usually have the luxury as they don’t mass produce products and need to be very careful with pricing if they want to turn a profit.
