The MSG Sphere is inching closer to opening.

The Las Vegas Strip’s newest event and entertainment venue, which is located behind the Venetian and slated to open this fall, has unveiled Sphere Immersive Sound, powered by HOLOPLOT — an ultra-advanced audio system uniquely conducive to its round shape.

“Sound, as part of the human experience, is very, very important,” Jim Dolan, executive chairman and CEO of Madison Square Entertainment, told members of the media at the Sphere on Thursday, adding that the venue will ultimately engage four out of the five senses, and “sound is key.”

The custom sound system, developed by Sphere Studios and Berlin-based HOLOPLOT, includes about 1,600 and 300 mobile loudspeaker modules.
