Main and Surround Speakers...Same Make and Model?

I have a question regarding main and surround speakers. Usually rear
surrounds are smaller, bookshelf kinds of speakers, while front left
and rights are generally larger, more powerful units. Why shouldn't
front and rears be the same? Wouldn't that ensure that the quality of
sound from playback be equal? A/V receivers send equal power to all
channels, so shouldn't make and model of all speakers for home theater
use be equal? Can someone smarten me up on this matter?

Please do!! That's just the way the director / producer / mixer would
like you to hear it.

In like 99% of households, there's the money and the space issue.
Since the rear channels are of "less importance", they can be smaller
(as long as the mids and highs can be compared to that of the fronts).
LF audio (and you probably know the joke about signals with those
wavelenghts) is then "managed" by the LFE channel.

There's also the issue about how diffuse the rears should sound.
Dipole speakers for instance, can make the sound source less
detectable, which is a pre for surround channels. Don't know much
about that subject though...

When using better speakers (if you had the money) for surround is ideal, you
don't have to get the same kind if a less expensive alternative could be
found. Just my $0.02.
