I just bought another inexpensive flat screen for the MH. It has virtual surround sound. I.E. fake surround sound!
It is THE most eeriest thing to be sitting at the dinette, TV in front and every now and then depending on what is being played the sound comes from behind me or off to the other side of the MH. Actually its down right creepy.
HOW do they do it without additional speakers?
"We must be willing to get rid of the life we've planned,
so as to have the life that is waiting for us".
It actually has to do with phasing the time the sound leaves the speakers. By properly setting the phase and timeing of a sound, the sound "appears" to come from a different location.
Now this actually only works when you are sitting in the right place, like in front of the TV. If you were off to one side, the effect would not happen.
It's actually the same technology I used to use in setting up sonar counter-measures (back before I retired).
Note: several years ago we were at a group campout, and there was a rather spectacular display of the Aurora. One of my friends walked up to me and asked what was causing them.
I started to explain.
The DW realized that he was, well, too drunk to understand so she interrupted me and said "Gnomes with Flashlights"
So that became my standard "non-technical answer" for technical questions, where people did not actually want the technical answer
2008 F350SD V10 with an 2012 Arctic Fox 29-5E When someone tells you to buy the same rig they own, listen, they might be right. When they tell you to buy a different rig then they own, really pay attention, they probably know something you don't.
A couple of other names for this is "simulated stereo" or "phantom" stereo. The explanation above is excellent and basically it happens so rapidly it "tricks" your ears into hearing something differently than what you think it should. Pretty neat huh?

Thanks.
"Gnomes with Flashlights", going to have to use that one!
It comes down to how one perceives sound or psychoacoustics. There several companies that offer virtual surround technology, but among those in the forefront is Dolby Laboratories. Been fortunate to personally work with their factory techs and engineers on an ongoing basis, some of whom have been responsible for designing their digital and cinema processors currently used by movie theaters and studios. All I can say is that they're really out there, and just possess a fundamental understanding of sound far beyond the vast majority of people. Pretty sure none of them will ever read this so as not to swell already enlarged heads. Take a look at their Dolby Virtual Speaker.
Having also worked and personally setup 3D motion picture systems worldwide, I've been equally impressed with Dolby's 3D digital cinema systems. It doesn't require a special silver screen as polarizing or shutter based systems typically do, and able to achieve an even field of vision while avoiding the typical hotspots, and dark edges of other 3D systems.
