2023 Vizio M215AW-K6 Soundbar System

Following up on our reports on the Vizio TVs, M-Series, and V-Series soundbars announced for 2023, Vizio introduced yet another M-Series soundbar with little fanfare, the M215aw-K6. This middle-of-the-range soundbar provides affordable access to Dolby Atmos via virtual surround sound in an easy-to-set-up 2.1 channel system for under $300.

Product Description: The M215aw-K6 is 36-inches wide and just over 2-inches high. The bar houses five speaker drivers within a 2.1 channel configuration. The woofer and tweeter for each of the left and right channels, plus the subwoofer driver equal 5 speakers. 

Wireless Subwoofer: An external wireless subwoofer is included that features a Bass Reflex ported design with one downward-firing 5-inch Driver.

Surround Sound Format Support: Although this sound bar can decode Dolby Atmos, DTS:X, Dolby Digital, and DTS 5.1 it uses DTS Virtual:X processing to approximate those formats within a 2.1 channel environment.

Tip: The M215aw-K6 does not have upfiring speakers specifically for Dolby Atmos, so DTS Virtual:X is used to produce height effects without the need for vertically firing speakers based on cues embedded in Dolby Atmos and DTS:X signals.

DTS TruVolume: This feature provides even volume levels and dialog presence. 

Sound Modes: Additional preset sound modes include Movie, Music, Gaming, Direct

System Frequency Response: 50 to 20kHz 

SPL (Sound Pressure Level): 100dB

Bluetooth ver 5.0: You can use Bluetooth to play music from compatible devices, such as smartphones, or connect an Amazon Echo device to access Alexa voice assistant features or play music from the echo device through the soundbar. 

Tip: Ethernet and Wi-Fi connectivity are not provided, thus there are no built-in smart features.
