In reality it's not that big a deal. Most content creators
understand this and don't put any significant content above

80 Hz

or so in the LFE track.

So it doesn't do this in DVDA/SACD?


My knowledge of DVDA/SACD is limited. However, I assume they
don't have an LFE channel and wouldn't have this issue.

Oh - one more question:

Let's say you have a 5.1/6/1/etc setup and are listening to
movies.

Given that this low-frequency cutoff effect is in place, what
is
the point where such response is virtually non existant in the
surround channels? This might be nice to put in the FAQ as if
there is virtually nothing below 50hz, for instance, then
buying
large surrounds is a moot point - just shop for 50hz capable
bookshelfs
and ther you go.

I'm not sure I complete understand your question.

There isn't any issues with the surround channels. Surround
output below the crossover frequency is routed to the subwoofer
output.

There are many preferences to the size and types of surrounds
(direct radiating, dipoles, identical speakers all around etc).
For my setup I prefer dipoles. I set surrounds to small so bass
is redirect to the sub. In certain cases you can have issues
with multiple sources of bass. The small setting can also
increase their dynamic range since the speakers don't have to
struggle with the bass.

Right - but you are saying that it falls off rather than a
sharp cutoff. So, say a standard 80hz cutoff - at what point
is more bass moot for surrounds?

Could you eloborate a little more about what you're asking?

A typical preamp/receiver has a 2nd order 12dB per octave high
pass crossover for speakers set to 'small'. The subwoofer output
has a 4th order 24dB per octave low pass filter.

So, if you set your crossover at 80Hz:

the subwoofer output will be attenuated
24dB at 160Hz
48dB at 320Hz
96dB at 640Hz, etc

the 'small' speaker will be attenuated
12dB at 40Hz
24dB at 20Hz
48dB at 10Hz

Note, this is the attenuation of the speaker electrical input not
the speaker output. The speaker may have additional rolloff of
it's own. For example, a typical surround speaker will have
insignificant output below 20-40Hz even when driven by a full
range signal. So the total attenuation is much higher than just
the crossover.
