The VIZIO Elevate soundbar with Dolby Atmos and DTS:X has an auto-rotating driver design that adjusts the position of the front height drivers to project the sound either forward or upward. The left, middle and right multiway speakers comprise two woofers, a tweeter and a passive radiator. They offer a frequency range of 30 Hz to 20 kHz, which delivers deep bass and clear high tones without neglecting the mid range.
