supplying more better sound quality:  however other speaker  focus only on raising the sound loudly which overloads the output power wattage on the loud speaker, so  the volume gets to a higher level ear piercing distortion (ie broken noises) becomes apparent.  and some Other units also has a default volume setting on its highest level that leads to led dimming when working .
