If you have money to burn ... set up a nice little experiment with the best
speakers you deem fit.
Produce a 1 Hz sine wave and play it through your amplifier to your speaker.
Watch the pretty woofer cone move in and out in once per second. Then turn
it up to the loud volumes that most people listen their favourite song to
and keep your nose active. Why? Because you'll smell the friggin' coil
burning!!!! Fact is, you're getting damn close to DC and that's a speaker
coil's major killer. That's why distortion kills speakers ... because the
amplifier is reaching its maximum output and is clipping and therefore
pumping DC rather than AC to your speaker at those peaks.
So let's all think realistically here. The bass you "feel" is usually at
around 80Hz for the kick off a kick drum. Anything lower than that may give
you a nice rumbling feeling, but even then, you don't really need to go any
lower than 20Hz and yes, even those super duper subwoofers can go subsonic,
but not ridiculously low either. Usually, 30Hz is the norm for a good
subbie, as experienced by my Soundstream Exact 12" in the car. I could
always port it to extend the bottom end to around 25Hz but there really is
nothing to be gained from that, personally. Furthermore, subbies that are
just made to kick and to wake up the whole neighbourhood, while sacrificing
a little bit of accuracy, don't go any lower than 20Hz as Magic previously
mentioned.
So while we can still reproduce frequencies below 20Hz, it is truly
pointless from an auditory sense, but also from a technical perspective. No
speaker coil would survive that unless it was a massive coil, with massive
power handling and massive amounts of cooling! If you want infrasonic
frequencies, then get a sofa that rumbles with the movie you're watching.
But if you want that kind of thing out of a musical piece, get a life.
Adios,

Correct, but somewhat misleading. Ordinary speakers, even the best, don't
go that low, because below about 20Hz it is more a matter of feeling than
hearing.
That is why we have self-amplified super subwoofers.
