How is that so hard - I would expect that with Lowthers?

Try it. Put the mic at the same distance (say 2m) from both, and drive
the pair in antiphase at the same level. Try doing this in your
listening room and if possible compare with doing it outside.

The problems a

A) most 'pairs' of speakers aren't actually that well matched in
sensitivity, frequency response, etc.


How much does that matter in most 'domestic' applications?

Means the two waveforms won't be 'mirro images' so won't null. Also means
that a nominally 'central mono' sound won't actually arrive as such at the
listening location as the contributions from each loudspeaker will vary
with frequency, etc, in a complex way. Thus, as with poor room acoustics,
tends to blur out the stereo image.


B) most chuck the power all over the room with a very poorly
controlled directionality pattern.


Again, what odds to anyone prepared only to pay as little as possible
for 'budget' speakers?

None. Just that the user won't be hearing clear stereo imaging. If they
have never heard this, or don't even know it is possible, then it may not
matter. Similary, if someone has heard this and doesn't wish it, then it
doesn't matter. However TBH I've never found anyone who listens to
classical/jazz/etc where the image is of a nominally 'real' acoustic layout
who didn't like this when they heard it.

The 'horns' can be shoved into almost any postion (provided there's one
on the left and one on the right somewhere) and the 'image' might move
a bit but it's quite academic - the music exists independently of the
speakers, wherever they are - up to a point, obviously! (Like I said
the other day - my 'sweet spot' is all the way from my room out to the
back door!! :-)

That's fine. But isn't the kind of stereo imaging I have been talking
about, and hear from the main system I use. I would not be without this,
but if you don't need it, it will make your life easier. :-)

Slainte,

Jim
