I have noticed in some recent magazines that "video stereo" speakers are
becoming more popular. I have also noticed that speaker manufacturers such
as Infinity and Polk are making such models. A quick once over of the specs
shows that in most cases they are almost identical to the "audio"
counterparts (i.e. drivers, frequency range, cabinet size...). Others
offer differences such as on boards power supplies and extra shielding or a
crossover at a different frequency.
Is it better to get the video stereo version for the TV or not? Why or why
not?

I have heard that when a reputable speaker manufacturer builds a speaker intended for video use, they take extra trouble to shield the magnets in the drivers so that you can put the speakers next to your video monitor without the magnetic field distorting the picture.

The theory behind so called "video speakers" is that they are
magnetically shielded and so will not perturb the electron beam
in your TV picture tube, which would produce reallly neat visual
garbage if and when it were to happen.
And the fact is that most magnetic speakers can visibly bend the
beam if waved in the right spots and close proximity to the tube.
However, the truth is that practically no good loudspeaker will have
a visible effect on the picture at any reasonable distance - like
right alongside (outside) the case. Maybe if you put the speaker
on top of th set you could have a problem, but why would you want to
do that?
In the unlikely event that there is a problem, simply move the
speakers farther away from the set. A few inches is usually plenty.
Last saturday I heard a video hi-fi tape played on an expensive (i
guess, they are all expensive) Sony stereo tv with real neat looking
stereo video speakers. It sounded awful compared to my rig at home
where I use a 30 year old Harmon kardon Citation amp with practically
dead tubes and either a pair of AR-4 (el cheapo for AR) speakers or,
more recently, a set of AR-1W/Janszen 65 speakers about 32 years old.
Either of these rigs blew the doors off the Sony with its video
speakers. And they don't look too bad either. The AR/Janszens are
kinda big, but they are newly painted white and look real purty.
The AR-4s were fairly small. I have even used Radio Shack Minimus
0.7's with good results.

The magnetic fields from speakers distort the picture.

I believe the difference between "Audio" and "Video" speakers is that
the Video speakers are shielded to keep the speaker magnets from interfering
with the magnetic deflection of the TV tube. This allows the speakers to be
placed next to the TV without bothering the picture.
