The AE22 is a low distortion, closed box speaker with an exceptional time domain performance (better than 40dB down within 5ms) and good horizontal off-axis consistency. It doesn’t have the flattest anechoic amplitude response you’ll ever see, nor the widest bandwidth, but from 60Hz to 25kHz it is about as musically accurate as moving-coil driver technology can achieve at the price.

The AE22 bass/mid driver is unusual in a number of respects. Its use of a metal cone ensures a linear amplitude response and minimal time-domain errors up to frequencies well above the crossover point. The metal cone also acts as a heat-sink that increases thermal power handling and reduces thermal compression. The driver also has an ‘underhung’ magnet/voice-coil system . An under-hung system — a short voice-coil in a long gap — is inherently more stable and linear than the more usual, and far cheaper, over-hung arrangement. The voice-coil is 50mm in diameter (25-38mm is typical at this price point) and has a black anodised aluminium former — again to increase thermal power handling and reduce thermal compression. The AE22 tweeter is a proprietary unit chosen for its good linearity, low compression, high power handling and ability to operate with a relatively low crossover frequency. It is often seen in high-end hifi speakers and is characterised by a clean and detailed sound with better than average high frequency dispersion.

Design philosophy
The art of designing a good nearfield monitor is to stay out of the way of the music. The monitor marks the point at which recorded music becomes real. It also often marks the point at which many musically significant distortions occur. Staying out of the way of the music means applying the best engineering practice to make sure, as far as the laws of physics allow, that any distortions are innocuous and that the music, not the monitor, is heard.

As much as the AE22 marks a return to roots for Acoustic Energy, it also marks a return to some fundamental engineering principles for nearfield monitors. In a market increasingly populated by monitors that deploy sophisticated digital electronics to provide peripheral functions, the AE22 deploys high value electronic and acoustic engineering to reproduce music more accurately and consistently in the studio environment. The AE22 is designed from the ground up to excel in the parameters that influence how accurately it presents what recording engineers need to hear, and how well it stays out of the way of the music.

Nearfield monitor specifications are traditionally all about low frequency extension and a flat axial frequency response. The AE22 is different. It has a frequency response specifically tailored to suit studio environments, applications and working practices, and low frequency extension limited by what can be accurately reproduced by a speaker of its size. It is far better to reproduce bass accurately down to 70Hz than inaccurately down to 40Hz. A typical contemporary monitor of similar size to the AE22 is likely to display a low frequency time delay of 20mS or more. The AE22’s low frequency time delay is 4mS. So if the kick drum sounds soft and the bass guitar’s lost its punch you can trust the monitor.

Every recording engineer knows how compression can affect the sound of a mix or an instrument. Not many however perhaps realize that audible compression mechanisms are present in all moving-coil speakers. And the smaller the speaker and the wider its bandwidth, the more significant compression is likely to become. By using closed box bass loading and a bass/mid driver with a 50mm voice-coil thermally bonded to an aluminium cone, the AE22’s thermal compression is reduced to insignificance, and it is immune from reflex port compression. So that eq you’re applying will work whatever the listening level.

Like compression, there’s a creative side to distortion – ask any guitarist. But creativity with distortion should be for the artist, not the monitor. And again, as with compression, as a speaker is required to reproduce a wider bandwidth its distortion levels will increase. Through heavy-weight engineering techniques usually unheard of at the price, such as an under-hung bass/mid driver voice-coil, the AE22 is designed to minimize distortion. So if you hear too much fuzz you can be sure it’s thanks to the guitarist.

We never imagined we’d want to write this about an Acoustic Energy product but we’ll have succeeded in our aims with the AE22 if it is taken for granted. Because the mark of a good nearfield monitor, apart from staying out of the way of the music, is that it sits there, session after session, consistently doing its job without anybody really noticing.

"We have found the AE22s trustworthy and mix friendly. With such an accurate, tight response time they provide a reliable reference point for mixes that don't disappoint! The AE22s have consistently won over visiting engineers and producers who love the familiar NS10 like response and feel at home mixing with these as nearfields."
