About the AE309²
The Acoustic Energy AE309² is a compact floorstanding loudspeaker designed for medium to large rooms. Acoustic Energy describes it as a significantly reworked model with new cabinet design and new drivers, while maintaining the same competitive positioning as the previous AE309. It uses paper/coconut-fibre bass-mid drivers and a new soft dome tweeter in a slim 18mm constrained-layer RSC MDF/bitumen cabinet with a rear slot port for controlled bass output. The speaker is offered in walnut, silk-touch matte black, or matte white finishes, and includes aluminium feet and spike covers.
