oh hi there i was just testing out my new speaker setup complete with tweeters
woofers and subwoofers what's that you want to know what those things are well
then i guess you came to the right place speakers of all kinds convert an
electrical signal into sound waves allowing us to listen to music and other
sounds from a recording or a live broadcast now
sound has an extremely wide frequency range overall much of which is actually
inaudible to humans so it's not really fair to expect that one type of speaker
should be able to produce sounds at reasonable listening volumes over the
entirety of that range that is where tweeters woofers and subwoofers come in
and yes before you comment down below about how i've noticed those aren't the
only three types of speakers you completely missed rotary subwoofers and
speaker type xyz i know that they're not the only three types of speakers
available but they are three of the most common types and they're what we'll be
focusing on today smartypants so let's start with the highs tweeters typically
tweeters cover the 2 000 to 20 000 hertz frequency range with 20 000 being the
top of the audible range for humans most tweeters use dynamic drivers which we
actually covered a bit in our video about headphone driver types right here
which utilize a voice coil suspended in a magnetic field which is attached to a
cone or diaphragm a thin membrane which actuates and moves air to produce the
sound that you hear but how do we determine what is and isn't a tweeter
then the answer is actually pretty simple size to produce a high frequency
noise the speaker must move extremely quickly and a small speaker is much
easier to vibrate fast enough to produce those higher frequencies than a large
speaker and though there isn't a specific size that quantifies a speaker
as a tweeter tweeters are usually going to be the smallest speaker on a
particular audio setup but luckily for
all you base heads out there not every speaker is a tiny little tweeter woofers
are broad spectrum low-wish frequency speakers with a typical range of 20 to
2000 hertz interestingly enough they were actually named woofers because
their deep heavy sounds can be reminiscent of the woof of a barking dog
like tweeters most woofers use a dynamic driver but unlike tweeters woofers are
almost always enclosed in an external housing enclosures increase sound
clarity and reduce distortion by preventing sound waves created at
different locations from crossing and ensuring that the woofers can always
receive the right amount of air for all the movement they need to do usually a
couple of strategically placed holes while woofers can produce sound at a
fairly wide range of frequencies they are a bit of a jack of all frequencies
master of none so to speak especially at the maximum and minimum of their range
so anything at or above 2 000 hertz is best left to the tweeters and the really
low stuff is best left to our last speaker type the subwoofer the name is
pretty self-explanatory they are sub or below a woofer and the typical frequency
range of a subwoofer is 20 to 200 hertz
making it a perfect organ shaker for a variety of purposes from raging parties
to casual drives to work in your alpine sponsored 98 civic of course not every
application of subwoofers is ridiculous when they're not configured to overpower
everything else they are an essential component of a well-balanced speaker
system that adds impact and depth to the explosions in your movies and the base
in your music in a home theater the subwoofer is usually situated in its own
separate enclosure and because it's designed to move large amounts of air
with strong slow accurate vibrations it
usually uses its own power source to maintain a reasonable listening volume
while doing so so there you have it why do we need different types of speakers
well because with only one type we would be limiting our ability to represent the
full range of human hearing accurately making for a much less satisfying
experience for audio enthusiasts everywhere and speaking of cruel
sponsors today's episode sponsor is fractal design and instead of having me
talk about their you know classy scandinavian designed computer cases
their efficient power supplies their excellent cooling products frackle
design has instead opted to have me eat
a ghost pepper on camera so
this is the package these were ordered from alamo
peppers alamo city pepper products something along those lines these are
dried peppers net weight of half an ounce and i'm going to go ahead and assume
that i'm not supposed to eat all of them in one go so we're going to do just just
one crack and open the seal
really not looking forward to this i probably shouldn't have done this to
whoa even the smell is strong oh i probably shouldn't have watched
someone else's pepper challenge before starting
but i did
okay
wow
i get hiccups when i'm something's really spicy
i don't know if i'm gonna get this down
i'm sorry there's no way
so thanks wow i don't know how other people are
i'm doing this
thanks for watching like if you liked
dislike if you disliked
i only swallowed a small amount of juice and i'm
on fire don't forget to subscribe comment suggestion future episodes bye
