Most consumers have frequently experienced and enjoyed surround sound, and yet they generally don't find it compelling enough to be worth putting in their homes.
Not like surround sound kits aren't available easily and cheaply. Consumers simply aren't interested. Huge 4K television despite very little 4K content being available? Yep. Surround sound? Nope. I've seen playback stats for a large streaming service, very few people bother.
or because most consumers dont have surround sound setup in their homes?
