We turn to the new FREKVENS combo and see, like on the Eneby 8”, removable front covers that reveal some speaker and a reflex vent on the smaller one.

Both parts of the combo can be run by AC or by a separately available IKEA-made battery pack.

The bigger one features a srewed-on cover plate on the bottom revealing a bay that fits the same energy source as the ENEBY 8”.

The compartment of the smaller companion can be opened with a coin and has room for another type of IKEA battery pack named BRAUNIT.

Strangely this battery is also suitable for IKEA’s automatic blind FYRTUR as part of their Smart Home series.

This interchangeability of batteries between devices is what we’d like to see more often in electronic devices.
