Just curious why you think it is "inherant that any speaker system rolls off
at the top or the bottom" ?
Tweeters are available which claim to be flat out to *well* past the limits
of human hearing (30Khz or more) and bass response flat down to below 30Hz
is readily obtainable, and going lower is simply a matter of how much
trouble you're willing to go to in regards to room size, and size, design,
and efficiency (or lack of) of the speakers. (Once you get down to 20Hz
you've basically reached the limits of human hearing - it now sounds like
pulses instead of a tone, and you feel it rather than hear it)
There is no inherant characteristics that you can ascribe to "all"
loudspeakers in such a way.
Anyway, say that a speaker rolls off at 40Hz instead of 30Hz, and 16Khz
instead of 20Khz(+) then cutting a bit of midrange around 600Hz is *not*
going to balance the sound... :)
Perhaps most of the speakers you've listened to just have a prominence
around the midrange - some people actually prefer that...or perhaps you
don't like the sound of midrange and reduce it a bit...(some other people
are like that)
