If the cutoff for them is higher than 80hz, if the drop off in
sound pressure above that point is more than 3db, consider something
else. There are too many surround systems out there that have a
noticeable gap between where their surround speakers start to drop
off in response and where their fronts or subs take over the base.

Those specs sound fine. Impressive for surrounds.

Yes, I understand why audio companies do those tiny surround or even
left-right fronts and centres and then use a sub for all the low
frequency stuff; It's a more profitable kind of speaker package than
full-range all round. Plus, Joe Average (for some inexplicable
reason) seems to think the sight of furniture and nicknacks around
a living room is preferable to a nice set of speakers so the smaller
the speakers are the, the more they appeal. You check the specs on
those packages, you'll see a severe dip in response from about
150hz down to the sub frequency. The only way to fill it is to
extend the sub's response, then the sub becomes localizable, which
you don't want. If you measure the response with a sound meter
from the listening position, you can see the weirdness.
