Floorstanding loudspeakers — Acoustic Energy AE309

The AE309 is a floorstanding loudspeaker from Acoustic Energy, built with notably high sensitivity and a comparatively benign impedance. The AE309 brings Acoustic Energy's considered engineering to an accessible floorstanding format.

Key specs that matter

Rated response is 38Hz to 30,000Hz within plus-or-minus 3dB. Sensitivity is notably high at 89dB into a comparatively benign 6 ohm load, with recommended amplifier power specified at 175W. At 90.0 x 17.5 x 28.0cm and 22kg, the AE309 maintains a manageable floorstanding footprint.

Sound and use context

Expect explosive dynamic headroom reflecting the notably high 89dB sensitivity, meaning this speaker reaches satisfying volumes readily from a wide range of amplifiers.

Pairing

The comparatively benign 6 ohm impedance and specified 175W power suit a broad selection of amplifiers.

Alternatives

Acoustic Energy's own AE320² sits above this model within the same broader floorstanding catalogue, worth comparing directly to find the right Acoustic Energy floorstanding tier.
