While little is known about the full range as yet, the company had previously announced two of the models. The HW-Q70R offers Dolby Atmos and DTS:X compatibility, and even though the speaker is only 2.3 inches high, Samsung has (again) clarified it does include up-firing speakers. 

Both sound bars include wireless subwoofers and Acoustic Beam technology that "uses an array of holes in the speaker to create a more dynamic, panoramic soundscape." The models also include Adaptive Sound technology, which is designed to tailor the sound to the content playing on your TV.
