The WAM7500 and WAM6500 are part of Samsung's new line of Curved Soundbars, and are set to be released at CES 2015. These speakers do not project sound in a single direction as is the case with a conventional stereo setup, but are rather designed to pump out audio in all directions using Samsung's proprietary 'Ring Radiator' technology.
The WAM7500 is a stand version while the WAM6500 is moveable, with the latter fitted with a built-in battery to enhance its portablility experience. However, both speakers are claimed by Samsung to provide an excellent balance between the bass and treble frequencies.
Samsung hasn't yet revealed pricing details for the Curved Soundbars; more details on pricing as well as availability are expected to be released at CES 2015 in the coming days.
