the shape of speakers.

hi
I would like to know why the majority of speakes have a vertical
desgin?

thanks.

So they put the drivers at the right level for your ears, while taking
up the least possible floor space.

Because they take up less floor space that way.

Because the tweeters need to be ay ear level, the other units don't
matter so much. So, at least for floor-standers, vertical makes
sense.

In addition, mounted horizontally, the difference in distance of each
driver from the listeners ears is usually greater. That causes the
sound from each driver to arrive at the listeners ears at a small, but
measurably different time, which leads to phase distortion. Mounting
them vertically minimizes (although doesn't entirely eliminate) the
difference and thus the time delays.

Coaxial mounting is one strategy to almost entirely eliminate delays
caused by differences in driver placement.

hi jak,
this answer start to make sense..
can you explain more..

thanks.

The three that come to mind are:

1) they take less floor space
2) the tweeter is at ear level
3) the drivers (woofers, midrange, tweeter, etc...) are all alligned
vertically so that phase problems are reduced

Horzontal phase problems are reduced, and horzontal dispersion
is optimised..

Yes :-)
of course....

Since we do not fly over the speakers...

- To align the drivers in a position where coherence is better in the
horizontal plane, for stereo.

- To raise the drivers off the floor, allowing better radirtion from MF and
HF drivers. Usually to around seated ear-height for domestic speakers, and
higher for PA scenarios where people are likely to be standing.

- Some like to reduce the frontage area (esp width) to do with dispertion
patterns and phase cancellations.

- take us less floorspace

- nicer position for vase

- prolly more...

The drivers in speakers are aligned vertically because our ears
are aligned horizontally. Lay a pair of speakers on their sides,
listen, and you'll soon hear for yourself.

All good fortune,

Phase problems may or may not be reduced by vertical alignment, but
dispersion is often better.

Vertical alignment is common, but not universal. There are reasons for
pulling the tweeter down and moving it as far as possible toward the edge of
the cabinet.

4) The narrower the cabinet, the higher the frequency at which diffraction
effects become significant.

Remember when speakers with stepped front panels were all the rage?

OTOH its good to keep the LF driver close to the floor to minimize the
effects of the dreaded "floor bounce"

Agreed.

Midrange drivers seem to be especially helped by narrow front panels.

Agreed.

While they have some dynamic range problems, on balance my NHT 2.5is have
stood the test of time better than any other speakers I've had in my nearly
50 year bout with audiophilia.

I presume the speakers would be toed in so the front panel always
faces the listening position, whether the drivers are horizontal or
vertical.

Perhaps pertinent is that in a seated position you'll move your
head left-and-right much more than up-and-down. With drivers mounted
vertically, the distance between each of them to the ear will pretty
much stay the same when you move your head left and right. If they're
horizontal, moving left-and-right changes the distance from your ear
to each of the drivers, changing the phase of the the sounds reaching
the ear from each, and changing the resultant sound.

Unfortunately, this doesn't explain all the pics I've seen of
NS-10's mounted horizontally. Or was that only done for looks?

They are so crappy it doesn't really make much difference !

There's no way to mount an NS-10 that will make it sound good. They're
good only for door stops and dumpster ballast.

Not only,
you can take pictures of them in your studio, so people know you're a
professional sound engineer :-)
