Mo uses POW Audio’s patented WaveBloom technology, which expands to create a passive radiator that supports the speaker’s high-quality drivers with an air-filled chamber. This added air results in better bass resonance, bigger volume, and improved overall sound quality, which cannot be achieved by typical, tightly packed speakers of comparable size that lack this expansive wave chamber. ​Because Mo is also magnetic, it can be mounted to a fridge, car bodies, and more. Mo can also easily be attached to the back of a smartphone (or any other non-magnetic surface) using the included Universal Mount.
