00:00:03.280 --> 00:00:09.679
oh hi there i was just testing out my new speaker setup complete with tweeters

00:00:07.120 --> 00:00:12.719
woofers and subwoofers what's that you want to know what those things are well

00:00:10.880 --> 00:00:16.160
then i guess you came to the right place speakers of all kinds convert an

00:00:14.480 --> 00:00:19.439
electrical signal into sound waves allowing us to listen to music and other

00:00:18.000 --> 00:00:24.400
sounds from a recording or a live broadcast now

00:00:22.080 --> 00:00:28.400
sound has an extremely wide frequency range overall much of which is actually

00:00:26.400 --> 00:00:33.360
inaudible to humans so it's not really fair to expect that one type of speaker

00:00:30.880 --> 00:00:37.120
should be able to produce sounds at reasonable listening volumes over the

00:00:35.120 --> 00:00:41.440
entirety of that range that is where tweeters woofers and subwoofers come in

00:00:39.440 --> 00:00:44.480
and yes before you comment down below about how i've noticed those aren't the

00:00:43.040 --> 00:00:48.960
only three types of speakers you completely missed rotary subwoofers and

00:00:46.879 --> 00:00:52.719
speaker type xyz i know that they're not the only three types of speakers

00:00:50.480 --> 00:00:57.039
available but they are three of the most common types and they're what we'll be

00:00:54.399 --> 00:01:02.320
focusing on today smartypants so let's start with the highs tweeters typically

00:00:59.440 --> 00:01:07.439
tweeters cover the 2 000 to 20 000 hertz frequency range with 20 000 being the

00:01:05.040 --> 00:01:10.720
top of the audible range for humans most tweeters use dynamic drivers which we

00:01:09.280 --> 00:01:15.040
actually covered a bit in our video about headphone driver types right here

00:01:12.799 --> 00:01:19.520
which utilize a voice coil suspended in a magnetic field which is attached to a

00:01:16.880 --> 00:01:23.759
cone or diaphragm a thin membrane which actuates and moves air to produce the

00:01:21.759 --> 00:01:27.840
sound that you hear but how do we determine what is and isn't a tweeter

00:01:26.000 --> 00:01:33.119
then the answer is actually pretty simple size to produce a high frequency

00:01:30.640 --> 00:01:37.680
noise the speaker must move extremely quickly and a small speaker is much

00:01:35.439 --> 00:01:41.119
easier to vibrate fast enough to produce those higher frequencies than a large

00:01:39.600 --> 00:01:45.920
speaker and though there isn't a specific size that quantifies a speaker

00:01:43.840 --> 00:01:51.119
as a tweeter tweeters are usually going to be the smallest speaker on a

00:01:47.759 --> 00:01:52.880
particular audio setup but luckily for

00:01:51.119 --> 00:01:58.240
all you base heads out there not every speaker is a tiny little tweeter woofers

00:01:55.600 --> 00:02:03.119
are broad spectrum low-wish frequency speakers with a typical range of 20 to

00:02:00.719 --> 00:02:06.240
2000 hertz interestingly enough they were actually named woofers because

00:02:04.719 --> 00:02:11.360
their deep heavy sounds can be reminiscent of the woof of a barking dog

00:02:09.119 --> 00:02:16.879
like tweeters most woofers use a dynamic driver but unlike tweeters woofers are

00:02:14.080 --> 00:02:21.120
almost always enclosed in an external housing enclosures increase sound

00:02:19.360 --> 00:02:25.200
clarity and reduce distortion by preventing sound waves created at

00:02:22.800 --> 00:02:28.800
different locations from crossing and ensuring that the woofers can always

00:02:26.800 --> 00:02:32.879
receive the right amount of air for all the movement they need to do usually a

00:02:30.720 --> 00:02:36.800
couple of strategically placed holes while woofers can produce sound at a

00:02:35.040 --> 00:02:42.239
fairly wide range of frequencies they are a bit of a jack of all frequencies

00:02:39.519 --> 00:02:46.800
master of none so to speak especially at the maximum and minimum of their range

00:02:44.160 --> 00:02:50.879
so anything at or above 2 000 hertz is best left to the tweeters and the really

00:02:48.800 --> 00:02:56.080
low stuff is best left to our last speaker type the subwoofer the name is

00:02:53.760 --> 00:03:02.159
pretty self-explanatory they are sub or below a woofer and the typical frequency

00:02:58.560 --> 00:03:04.640
range of a subwoofer is 20 to 200 hertz

00:03:02.159 --> 00:03:09.280
making it a perfect organ shaker for a variety of purposes from raging parties

00:03:07.040 --> 00:03:14.720
to casual drives to work in your alpine sponsored 98 civic of course not every

00:03:12.159 --> 00:03:18.000
application of subwoofers is ridiculous when they're not configured to overpower

00:03:16.480 --> 00:03:22.720
everything else they are an essential component of a well-balanced speaker

00:03:20.239 --> 00:03:26.480
system that adds impact and depth to the explosions in your movies and the base

00:03:24.480 --> 00:03:31.040
in your music in a home theater the subwoofer is usually situated in its own

00:03:28.959 --> 00:03:36.239
separate enclosure and because it's designed to move large amounts of air

00:03:32.959 --> 00:03:38.239
with strong slow accurate vibrations it

00:03:36.239 --> 00:03:42.799
usually uses its own power source to maintain a reasonable listening volume

00:03:40.159 --> 00:03:46.239
while doing so so there you have it why do we need different types of speakers

00:03:44.319 --> 00:03:50.480
well because with only one type we would be limiting our ability to represent the

00:03:48.239 --> 00:03:54.319
full range of human hearing accurately making for a much less satisfying

00:03:52.319 --> 00:03:58.000
experience for audio enthusiasts everywhere and speaking of cruel

00:03:56.159 --> 00:04:02.239
sponsors today's episode sponsor is fractal design and instead of having me

00:03:59.680 --> 00:04:06.799
talk about their you know classy scandinavian designed computer cases

00:04:04.959 --> 00:04:11.920
their efficient power supplies their excellent cooling products frackle

00:04:08.879 --> 00:04:15.439
design has instead opted to have me eat

00:04:11.920 --> 00:04:17.120
a ghost pepper on camera so

00:04:15.439 --> 00:04:22.240
this is the package these were ordered from alamo

00:04:19.600 --> 00:04:26.080
peppers alamo city pepper products something along those lines these are

00:04:24.160 --> 00:04:29.919
dried peppers net weight of half an ounce and i'm going to go ahead and assume

00:04:28.160 --> 00:04:33.360
that i'm not supposed to eat all of them in one go so we're going to do just just

00:04:32.400 --> 00:04:37.440
one crack and open the seal

00:04:35.840 --> 00:04:42.639
really not looking forward to this i probably shouldn't have done this to

00:04:40.240 --> 00:04:46.160
whoa even the smell is strong oh i probably shouldn't have watched

00:04:44.720 --> 00:04:49.520
someone else's pepper challenge before starting

00:04:48.639 --> 00:04:51.919
but i did

00:04:52.400 --> 00:04:55.400
okay

00:05:01.680 --> 00:05:04.680
wow

00:05:10.880 --> 00:05:15.759
i get hiccups when i'm something's really spicy

00:05:16.639 --> 00:05:20.759
i don't know if i'm gonna get this down

00:05:28.080 --> 00:05:31.199
i'm sorry there's no way

00:05:34.160 --> 00:05:42.560
so thanks wow i don't know how other people are

00:05:39.919 --> 00:05:42.560
i'm doing this

00:05:44.960 --> 00:05:51.199
thanks for watching like if you liked

00:05:48.080 --> 00:05:52.639
dislike if you disliked

00:05:51.199 --> 00:05:55.360
i only swallowed a small amount of juice and i'm

00:05:54.240 --> 00:06:01.000
on fire don't forget to subscribe comment suggestion future episodes bye
