This is the “big brother” of the Emberton II model: instead of two speakers, there are already four with 360-degree sound (two 10 W each and two 20 W each), the frequency range is from 50 Hz to 20 kHz.
The case is protected according to the IP67 standard: it is not afraid of dust and can withstand immersion to a depth of up to 1 meter for up to 30 minutes. The column will withstand drops from a small height.
On the case there are controls for adjusting bass and treble. In a proprietary application, you can adjust the equalizer and combine multiple speakers for synchronous playback.
Battery life is up to 20 hours. The column can also be used to charge other devices.
Middleton is a large speaker that weighs 1.8 kg. The kit even has a strap for easy transportation, although this is more of a home option. The novelty was priced at $299.
