Bookshelf Speakers — Acoustic Energy AE100

The Acoustic Energy AE100 is the small stand-mount model of the 100 Series, the British brand's entry-level loudspeaker range. This is the second-generation AE100², in which Acoustic Energy fitted a larger mid/bass driver, a new cabinet, a new crossover and a new tweeter-to-woofer transition compared with the original AE100. It was designed to reach high sound pressure levels from a small enclosure that fits on stands or bookshelves.

Key specs that matter

The AE100² is a ported two-way with a 25mm fabric dome tweeter and a 130mm doped-paper-cone mid/bass unit, crossing over at 2.9kHz. Frequency range is 51Hz to 26kHz, sensitivity is 87dB, nominal impedance is 6 ohms and power handling is 120W, with a peak output of 112dB. Each speaker measures 290 x 165 x 250mm, and the pair weighs 9.2kg. The finishes are black, satin white and walnut vinyl veneer, and the slim cloth grilles attach magnetically.

Engineering and use context

A high-power, long-excursion motor lets the small mid/bass cone move enough air for useful volume and bass from a compact box. Doping the paper cone adds internal damping and stiffness, so the driver works cleanly up to a higher crossover point, and the step from a 110mm cone in the first-generation AE100 to 130mm in the AE100² adds radiating area for more output and extension. The tweeter sits in Acoustic Energy's Wide Dispersion Technology waveguide, which matches its dispersion to that of the mid/bass driver through the crossover region and keeps the off-axis response more consistent. The cabinet is made from 15mm high-density fibreboard (HDF) with tuned internal bracing against panel resonances, and its styling follows the 500 Series. Bass is vented through a rear slot port, whose large cross-section reduces air turbulence and port noise compared with a small round port, and this tuning limits the effect of nearby walls on the bass. For the second generation the crossover was redesigned, from its components to its layout.

Pairing

Thanks to its moderate impedance and sensitivity, the AE100² pairs with most integrated amps and AV receivers that stay within its power handling. In small to medium rooms the speaker can go on a shelf or on stands with some space behind for the rear port, and in larger rooms or home cinema systems a subwoofer adds the lowest octave below its bass limit.

Alternatives

Acoustic Energy's AE500 is the stand-mount of the higher 500 Series, with a larger cabinet and upgraded drivers.
