Acoustic Energy AE Active review

Active speakers – speakers with built-in amplification directly powering the drive units – have become more and more popular these days. Their space-saving form negates the need for separate boxes for amplifiers and trailing cables, reducing clutter and making for neater systems.

Most active speakers these days also come with built-in DAC and digital inputs, sometimes a phono stage, and more often than not hi-res network streaming or at least Bluetooth included for ultimate all-in-one convenience. Acoustic Energy bucks this trend by keeping its new AE Active speakers purely analogue.

This new model builds on the five-star, Award-winning AE1 Active speakers we tested back in 2018 and have highly recommended since, and features updated acoustic technology and refined design for a new generation.

Build & design

The Acoustic Energy AE Active are a fully active two-way design, with 50W of Class A/B amplification powering each drive unit. That’s a total power output of 200W, with the amplifiers being refined in this new generation to improve dynamic capability. Each speaker has its own mains plug for power, with the revised amps fed by high-quality linear power supplies to ensure a consistent, low-noise performance throughout the frequency range.

The 40-year-old Acoustic Energy brand continues its tradition of using metal drivers in its new active speakers. The 27mm aluminium dome tweeter has a new rear chamber for reducing distortion at certain frequencies in the crossover region, and is combined with a dedicated waveguide to deliver a wide soundstage.

These speakers use the same 12.5cm mid/bass driver that was developed for the recent AE1 40th Anniversary passive speakers. This is a “pure-piston” ceramic/aluminium cone that is low in mass but very stiff, and has been engineered to minimise cone flex and distortion.

The analogue filters have been improved to minimise any phase disturbances. There is a rear-facing bass slot port that has also been updated, while internally the cabinet has had extensive bracing and internal damping panels to further improve performance.

The cabinets themselves have been subtly refined, with a neater trim around the drivers that overall looks rather smart and subtly elegant. The speakers are available in three finishes: high gloss black or white, and a new natural walnut wood veneer. Our sample’s wood veneer finish feels lovely to the touch, with a smooth texture and high quality finish throughout.

The standmounts have a fairly compact footprint and look most at home on dedicated speaker stands, although they could be placed on a large, sturdy desk if you are using them as nearfield monitors. You’ll just need to make sure both speakers are within reach of a mains power socket.

Features

The AE Active speakers eschew any digital or streaming elements entirely. Acoustic Energy says it experimented with modern features such as wireless streaming, switch mode power supplies, Class D amplification and DSP, but ultimately didn’t want to compromise the pure audio performance. The AE Active have a fully analogue signal path that avoids any digital processing entirely in the quest to preserve the original audio file’s integrity.

As such, you get two analogue inputs: a pair of balanced XLR inputs and a pair of stereo RCA inputs.

On one hand, this purist approach is commendable, but it’s a little old-fashioned and won’t appeal to everyone, particularly those looking for an easy solution. There’s a reason most active speakers these days – such as the KEF Coda W, Fyne Cubitt 5 and Cambridge Audio L/R S – come with Bluetooth and a variety of digital inputs to work with modern sources including TVs and laptops.

On the other hand, this pared-down approach does keep the Acoustic Energy rather flexible and future-proof. The speakers have integrated volume control, which means you can directly plug in a source such as a CD player or hi-res music streamer. You can also plug in a preamp or an external DAC to widen the connectivity, and it allows for a potential upgrade path down the line.

On the back panel on both units, you’ll find bass and treble controls to fine-tune the sound to the room they’re in, especially if dealing with less-than-ideal placements. One new feature is the auto on/off switch that lets you choose between leaving the speakers on permanently or activating standby mode after 15 minutes of inactivity.

That the active speakers come with built-in volume control is great news – this means they don’t require a separate preamp with volume control to function, such as the more premium ATC SCM20ASL active speakers do.

The only real complaint we have is with the placement and design of the volume controls. The dials are placed on the speakers’ back panel – this might be fine if the speakers are within reach on a desk, but it’s not practical if they’re on stands and you’re on your sofa. No, there is no remote control included here.

The bigger issue is that there are independent volume controls for each unit, with no clear markings on the dials. This means there is more chance of the volume not being perfectly level and balanced between the units, as you have to set them individually. We would much prefer it if there was one volume control that controlled both speakers’ levels.

A preamp or source with volume control comes in handy here, such as the Naim Uniti Atom Headphone Edition music streamer we used throughout testing, so you can take the guesswork out of it.

Sound

Placed on stands and with the Naim Uniti Atom HE streamer playing a variety of radio, WAV and hi-res FLAC songs, the AE Active don’t take long to show their talents.

The control they have over every note is astounding at this level. The piano notes in Alicia Keys’ Fallin’ sound tremendously composed and land with solidity and confidence. Each note starts and stops with unerring punctuality, with the rhythm of every song we play being marshalled with a kind of military precision that is hugely impressive.

The amount and quality of bass coming from these not-particularly-large cabinets is also impressive, and we had a blast playing tracks with intense basslines just to hear what these AE Actives can do. There is real muscle and impact to the basslines of Major Lazer’s Pon de Floor, but there’s agility and texture here too. It’s all pulled taut and has the immediacy that is inherent in active speaker designs.

The busy arrangement and high-octane energy of the track are handled with ease by the speakers, too, with every note sounding crisp and positioned accurately in the soundstage – but without ever losing the party vibe.

Dynamically, the AE Actives are fantastic. The snappy transient response of these active speakers means sudden shifts in quiet-to-loud moments are brilliantly and speedily communicated, while slow-burning moments – such as Clint Mansell’s instrumental Moon soundtrack – sound fluid and retain their sense of tension.

Play Kate Bush’s Watching You Without Me and the AE Active reveal high notes with the right mix of clarity, headroom and bite, but without any undue brightness or sharpness. The overall sound from these active speakers is rather clean and with low-distortion throughout the frequencies, which also means we can enjoy listening at high volumes without hardness or woolliness creeping in.

The stereo imaging is similarly focused and composed, with voices showing off just how well integrated the AE Actives' drivers are. The speakers have no problem revealing the different voices, intonations and personalities in Eminem’s Stan. From The Unthanks’ delicate, nuanced vocals on Mount The Air to Eminem’s rapid-fire, ferocious rapping on Godzilla, the AE Actives reveal the character and intensity of every song with a good amount of detail and nuance.

The Acoustic Energy speakers are just about transparent enough that you are aware of the distinct recording qualities of albums from different eras, but they don’t make too much of a fuss over the quality of each track. The overall sound could perhaps be a little more fluid and airy-sounding, and they may struggle to fill very large rooms. When listening in our larger 3m x 7m x 5m (hwd) test room, the AE Actives sound a touch dynamically restrained, but they come to life in our smaller 3m x 4m x 7m room, with a bit of breathing room from the back wall to balance the bass performance.

We swap to a price-equivalent separates amplifier and speaker pairing of the Arcam A5+ and Acoustic Energy AE300 Mk2 (both current Award-winners in their respective categories), and find this offers a more relaxed and wider soundstage. They sound rather soft in the bass, though, and don’t go as deep either. Overall, they can’t match the speed, precision and agility of the AE Active speaker.

Verdict

The Acoustic Energy AE Active are a niche product in today’s audio landscape, but they are a tremendously talented and capable pair of active speakers. They are a viable alternative to a traditional separates pairing at this price, and could well be the last chain in your hi-fi system you’ll have to update. Highly recommended.
