Acoustic Energy’s AE1 Multi-Driver Loudspeakers (Part 2)

Slave to the rhythm

If the AE1 looked like the future, imagine how it sounded. All those big, ponderous boxes with multiple drivers slipping in and out of phase with one another at random points couldn’t hold a candle to this little loudspeaker’s speed and dexterity. With its two, super-stiff drivers set into a small rigid cabinet, it comes over as a model of clarity, insight and resolution. But there’s more – even by today’s standards, it’s still one of the most energetic boxes around. It comes over as fizzing with enthusiasm, it has enormous vigor and brio. No matter what sort of music you feed it, the AE1 makes the music magic. No surprise perhaps that it was designed by Phil Jones, a bass guitar-mad musician.

Unlike so many other mini monitors, they show real grace under pressure

In a sense, this musicality is one of the unintended consequences of the speaker. By designing out all the compromises and imperfections of the big boxes of the seventies, and going for a stripped-back, paired down approach, it showed just how much the complexity of its forebears sucked the life out of recordings. The primary object of the AE1 was, of course, neutrality and transparency – the ability to give an open window on the recording in a way that the BBC LS3/5a tried to, but never quite managed – but it also happened to make it far easier to focus on the rhythmic as well as the textural aspects of the music.

Still, its wonderfully fast attack transients, finely etched low-level detailing and purity of phase can’t make up for its one handicap – size. The larger you make a speaker, the more problems you create for yourself in trying to rein in the cabinet and marry the multiple drivers, but you also give the design a chance to make deep, realistic bass. Being so small, of course, the AE1 deftly sidesteps those size-related pitfalls, but cannot change the law of physics and generate vast tracts of grumbling low frequencies. Acoustic Energy claims the speaker begins to tail off at 70Hz, which isn’t a bad figure for such a small box, but still you’d never confuse this with a large floor stander!

In some respects the AE1 sounds like a physically small speaker – there’s no getting away from this. Feed it some drum and bass from Alex Reece, in the shape of Feel the Sunshine and there are drums, but no bass – well, not much, anyway! The bottom octave that floor standing speaker users take for granted simply isn’t there. But this doesn’t spoil things; because everything else is so right about the AE1, your attention is simply drawn to what you can hear, which is music rendered in an open and engaging way, with fine image placement, excellent depth perspective and the ability to throw the soundstage far beyond the position of the speakers themselves. Connect the AE1s up to a good modern solid-state amplifier with a fair smattering of power – a Naima SuperNait being an ideal example – and you will be amazed by how loud these little boxes go without break up. Unlike so many other mini monitors, they don’t compress things until they’re on the ragged edge; they show real grace under pressure.

Little box of tricks

One of the finest designs of its day, the AE1 harks back to a time when loudspeakers were a little more focused than they are now. It was a design that did many things brilliantly, yet had serious shortcomings in other respects. For that this little box will be fondly remembered and never forgotten. Indeed its manufacturer is so proud of it that, a few years ago, it started remaking the AE1 as the ‘AE1 Classic’, such was the demand. New or secondhand, it’s little audio dynamite!

Buying

Because the AE1 has been around so long, there’s no shortage of them knocking around the secondhand scene. An early pair can be had from under $478.65, if you’re really looking – but expect to pay around $797.75 for an unmarked, boxed set with the optional wood veneer finish, or more if it’s the newish AE1 Classic variant. Because many of them have seen use in studios as near-field monitors, many will be scratched or marked, or indeed hammered! The drive units are still available from Acoustic Energy, so it’s not game over if a tweeter blows, but obviously a ‘one domestic owner pair’ is better than one that’s had to really work for a living! Factor this into the price. Another consideration is where you’re going to put them. The original AE1 speaker stands are no longer available new, but can be had used for under $159.55, and there’s always the Parrington Dreadnought stand if you can’t find the AE version. AE1s demand heavy, mass-loaded stands, affixed to the floor as firmly as possible, between 16in and 24in high – depending on your listening position. A good pair of speakers on the right stands will give a memorable listening experience.
