Transmission line nonsense, was Bose 901
Dick Pierce wrote:
And to talks about something that's shorter than a wavelength
as a transmission line itself is bordering on absurd. Consider
the fact that at those frequencies, you're actually looking at
the system as a Helmholtz resonator with a whopping large
acoustic inertance, a tinu effective acoustic cimpliance, and
a pretty high absorbtion loss, and then calculate what happens
to the effective pahse shift as you move through that overdamped
resonance.
So what you say is that a "transmission line speaker" is a bass reflex box
with a very small box volume and a very large port volume?
Kind regards

Bud Fried (of, among other things, IMF fame) did more to set back
the amateur's grasp of physical acoustics then damned near anyone
else: he, regretfuylly, was a very persuasive, charming personality
who was otherwise clueless about acoustics.
