It is not so much a matter of quality (though I don't think anyone
questions Klipsch quality) as it is design parameters. You can't
just stick any old woofer, no matter how fancy-looking, in a K-horn
and expect it to work.

Modern woofers, especially those designed for subwoofer duty,
typically have long-throw designs, soft suspensions, and very low
resonant frequencies. Such a speaker would sound _HORRIBLE_ in a
K-horn. Modern speakers, often used in acoustic suspension boxes,
are made the way they are because the air trapped in the box adds
to the effective stiffness of the cone, raising the resonant
frequency.

A horn does exactly the opposite. The column of air in the horn
acts like extra mass on the cone, _LOWERING_ the resonant frequency.
And, incidentally, loading the speaker so that it doesn't need much
excursion. A long-throw, low Fs speaker in a K-horn would flop
around like a bird with two broken wings. The K-horn speaker has
a high resonant frequency and short throw, because it doesn't _NEED_
long throw.
