reviews
Manufacturer details

- Mains voltage: 100 – 240 V
- Drivers: 5" woofer-midrange, 1 x 1" dome tweeter
- Output power (RMS/Max.): 2 x 35 / 2 x 75 W
- Frequency Response: 38 - 40,000 Hz
- Crossover Frequencies: 3500 Hz
- Dimensions (WxHxD): 175 x 290 x 205 mm
- Weight: Active Speaker: 4.4 kg, Passive speaker: 3.8 kg

Compact, but with a sound of a much larger model While it shares the 25 mm tweeter dome with its siblings, it claims the compact, but powerful, 125 mm bass-midrange driver for itself. This delves down to a frequency of 38 Hz, which should be more than ample in many cases. At the other end of the frequency band it reaches 40,000 Hz. As a result, the Reference 2A can definitely be used for high-res material.
The amplifier that is integrated in the active speaker delivers 2 x 35 watts of continuous power (RMS) or 2 x 75 watts of peak power. The elaborately equipped crossover sorts the music signal at 3,500 Hz. Since both amplifiers are located in one speaker, you only need one socket for the power supply; the passive speaker is simply connected to the active unit using the supplied cable.
Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- The brand's THX Ultra2 certified speaker sets are known for their compact design, achieving stringent THX requirements while maintaining smaller dimensions than many competitors, sometimes using only one subwoofer where others need two.
- The AEH-400-ATM auxiliary loudspeakers offer a unique two-in-one design, functioning as both Dolby Atmos enabled speakers and direct radiators via a simple toggle switch, providing flexibility for different immersive audio setups.
