1
00:00:00,000 --> 00:00:03,840
Everybody knows that a bigger subwoofer means more bass.

2
00:00:03,840 --> 00:00:06,900
But what about longer subwoofer?

3
00:00:06,900 --> 00:00:11,780
I'm gonna catch a cable. I'm gonna ruin every, we're good. Longer subwoofer.

4
00:00:11,780 --> 00:00:14,780
This is the Bose Acoustic Wave Cannon System

5
00:00:14,780 --> 00:00:18,380
and it's f***ing dumb. It's 12 feet long and it can blast listeners

6
00:00:18,380 --> 00:00:23,980
with super low wubs, it up to an ear-damagingly high 109 decibels.

7
00:00:23,980 --> 00:00:28,500
And all we had to do was extract it from the home of some maniac on Facebook Marketplace.

8
00:00:28,500 --> 00:00:32,620
But just how bassy can this thing get? I mean, it's called a sound cannon.

9
00:00:32,620 --> 00:00:35,780
But as somebody who craves the thunder of the wubs,

10
00:00:35,780 --> 00:00:40,600
I have very high expectations. The only problem is, it's not built yet.

11
00:00:40,600 --> 00:00:45,380
So I've enlisted help of good friend of the channel, DMS, so that we can get this thing online,

12
00:00:45,380 --> 00:00:48,900
figure out why it even exists. And hopefully we can make it sound

13
00:00:48,900 --> 00:00:52,740
like one of those old Maxwell tape ads. Let's do it, let's do it.

14
00:00:52,740 --> 00:00:56,820
Welcome to the latest installment of, we bought this thing, we do not know what we're doing,

15
00:00:56,820 --> 00:00:58,380
but we're gonna use it anyways.

16
00:00:59,820 --> 00:01:05,740
Hey Adam, there's something in here. Huh? Oh hey, it's our segway to our sponsor.

17
00:01:05,740 --> 00:01:10,340
So the script says unbox it, but there's not really a whole lot of unboxing.

18
00:01:10,340 --> 00:01:15,020
Yeah, the box probably isn't around anymore because the instruction manual says copyright 1988.

19
00:01:15,020 --> 00:01:18,620
But what exactly did we get? I see that we have a big tube

20
00:01:18,620 --> 00:01:22,420
and I see the driver for the subwoofer, but we also have a bunch of other stuff.

21
00:01:22,420 --> 00:01:25,580
Yeah, so like many other Bose products,

22
00:01:25,580 --> 00:01:28,740
this requires a sort of proprietary power system

23
00:01:28,740 --> 00:01:32,220
because this uses DSP, digital signal processing

24
00:01:32,220 --> 00:01:36,940
to make it sound a certain way. It's just a fancy way of saying they EQ'd it to make it sound the way they want.

25
00:01:36,940 --> 00:01:40,060
So you couldn't just drop this thing into any system,

26
00:01:40,060 --> 00:01:43,580
you need this. You technically could, however,

27
00:01:43,580 --> 00:01:48,140
you would need to know what they did EQ-wise if you want it to sound the way it should.

28
00:01:48,140 --> 00:01:54,220
But like, I don't think it's really a normal speaker because I have never seen a speaker that is 12 feet long.

29
00:01:54,220 --> 00:01:57,300
It is a normal speaker. You could actually replace this.

30
00:01:57,300 --> 00:02:01,460
It's just got a simple speaker tap on the side and this is just PVC pipe.

31
00:02:01,460 --> 00:02:07,420
Wait, you're saying we spent $1,000 plus however long it took to get this here for PVC pipe?

32
00:02:07,420 --> 00:02:10,660
Yes, but it's a lot less than people would have spent on it in the 80s.

33
00:02:10,660 --> 00:02:16,020
Was PVC expensive in the 80s? No, actually the reason you would build a speaker like this,

34
00:02:16,020 --> 00:02:19,900
specifically a subwoofer is because this is the cheapest way you could possibly build it.

35
00:02:19,900 --> 00:02:24,180
Wow, that's so Bose of them. But that doesn't mean it isn't cool.

36
00:02:24,180 --> 00:02:26,580
I mean, who hasn't wanted to own a cannon?

37
00:02:29,580 --> 00:02:33,540
It's like a freaking bass bazooka. Yeah, my favorite thing about it is how compact it is.

38
00:02:33,540 --> 00:02:36,780
Something you'll notice about this is it's open on both ends.

39
00:02:36,780 --> 00:02:39,780
So there's not really an enclosure, right? Oh yeah.

40
00:02:39,780 --> 00:02:43,140
That's because this is what's called a parallel port.

41
00:02:43,140 --> 00:02:48,380
Now, the way this works is essentially ports, they help make one bass frequency louder than the rest

42
00:02:48,380 --> 00:02:51,660
and we have one big one and one short one so we can kind of combine those

43
00:02:51,660 --> 00:02:56,660
and fill out a bigger range of bass. So it's not just a one note, one trick pony.

44
00:02:56,660 --> 00:03:02,460
Another benefit, or maybe it's a downside, a characteristic of having your bass in a long tube

45
00:03:02,460 --> 00:03:07,100
is that it makes it very directional, which means that the bass only goes

46
00:03:07,100 --> 00:03:10,300
where you want it to go, ideally.

47
00:03:10,300 --> 00:03:15,180
This is why the guy who owned this previously had this actually mounted in his dining room cabinets,

48
00:03:15,180 --> 00:03:18,780
but it blasted all of that sound into his home theater

49
00:03:18,820 --> 00:03:22,580
so it maybe didn't disturb the dinner guests too much

50
00:03:22,580 --> 00:03:26,900
while he was sitting by himself watching The Dark Knight for the 1700th time.

51
00:03:26,900 --> 00:03:31,060
Usually bass is omnidirectional, means it emits in every direction,

52
00:03:31,060 --> 00:03:34,580
pierces through walls, that's why you can hear your neighbors playing loud music.

53
00:03:34,580 --> 00:03:38,540
But the way this thing is canceling sound out is the bass frequencies are so long

54
00:03:38,540 --> 00:03:41,660
you measure them in feet out like this.

55
00:03:41,660 --> 00:03:44,780
So you're saying this cancels out the frequencies?

56
00:03:44,780 --> 00:03:50,300
Yes, the distance from that port to the other one is so big that those frequencies overlap in the air

57
00:03:50,300 --> 00:03:53,780
and cancel each other out. So if you're sitting right in front of it, good bass.

58
00:03:53,780 --> 00:03:57,500
But if you're the guy next door, not so good bass.

59
00:03:57,500 --> 00:04:00,500
Whoa, whoa, whoa, before we do this, I actually wanna hear what this is gonna sound

60
00:04:00,500 --> 00:04:04,180
like without the tube, because that way I'm gonna know what that tube do.

61
00:04:04,180 --> 00:04:07,620
That means we need to figure out what that rat's nest is. Whoa.

62
00:04:07,620 --> 00:04:12,300
Oh, yeah, that is an extra driver. Useful if you blow one up.

63
00:04:12,300 --> 00:04:16,180
Do you think we're gonna do that? I hope not, but it's not outside the scope of possibilities

64
00:04:16,180 --> 00:04:20,820
and I don't wanna make any promises. We're gonna blow it up. So this thing's weird.

65
00:04:20,820 --> 00:04:24,100
Like a lot of things were in the 1980s audio wise,

66
00:04:24,100 --> 00:04:28,580
it takes balanced inputs on these XLRs.

67
00:04:28,580 --> 00:04:32,100
It's just weird seeing it wired for it on binding posts

68
00:04:32,100 --> 00:04:36,780
that then go out to XLRs. Yeah, why not just XLR the whole way?

69
00:04:36,780 --> 00:04:41,820
Why not indeed? I'm gonna take this thing off of here

70
00:04:41,820 --> 00:04:43,820
just because since we're not using it,

71
00:04:44,820 --> 00:04:48,620
I don't wanna leave some bare wires sitting around that might just short out on us.

72
00:04:48,620 --> 00:04:54,180
It's just weird that there's binding posts for everything. I'm not used to seeing binding posts leading out to RCA's.

73
00:04:54,180 --> 00:04:58,820
And why do they have balanced inputs and unbalanced outputs?

74
00:04:59,860 --> 00:05:02,980
What were they thinking here? What was the plan?

75
00:05:02,980 --> 00:05:06,180
It's almost like you could like give a press conference

76
00:05:06,180 --> 00:05:09,900
from here. I'm John Bose, inventor of the Bose headphones

77
00:05:09,900 --> 00:05:13,580
and Soundwave Canon. You wanna overprice the box?

78
00:05:13,620 --> 00:05:17,020
We got you covered. Sweet. So now we should be able to play something on this.

79
00:05:17,020 --> 00:05:21,500
Yes. I'm gonna set this beautiful thing right here on top.

80
00:05:21,500 --> 00:05:25,020
Oh yeah, look at that. Why are you not making sound?

81
00:05:25,020 --> 00:05:27,020
Why have you forsaken me base tube?

82
00:05:31,180 --> 00:05:34,180
Hey. It's doing a little bit. Update.

83
00:05:34,180 --> 00:05:37,980
Turns out that this Bose controller doesn't really work.

84
00:05:37,980 --> 00:05:41,460
So we plugged it into this SVS prime wireless pro sound base

85
00:05:41,460 --> 00:05:45,580
and plugged that directly into the subwoofer. And would you know it?

86
00:05:45,580 --> 00:05:48,020
It works. I'm tired, boss.

87
00:05:52,540 --> 00:05:54,980
That's noise coming from me adjusting the knob here.

88
00:05:58,940 --> 00:06:01,220
Well, they just got some peaks. Yeah.

89
00:06:04,060 --> 00:06:07,420
There's the, that's the frequency of the tube that's sitting right there.

90
00:06:08,420 --> 00:06:12,100
Is it making that thing? It's resonating off this.

91
00:06:12,100 --> 00:06:16,260
So I'll just sit on the couch and see if this makes sense. Do we want to rotate it so that it fits?

92
00:06:16,260 --> 00:06:20,100
Fits where? Directly. So it faces the couch? Oh, you should.

93
00:06:20,100 --> 00:06:23,100
This is actually the correct orientation. What? Yeah.

94
00:06:23,100 --> 00:06:26,100
What? You don't want to be in front of it.

95
00:06:26,100 --> 00:06:29,100
You don't want to. You technically want to be on this side. Why?

96
00:06:29,100 --> 00:06:34,420
If you are on this side, you're going to be farther from one side to the other.

97
00:06:34,420 --> 00:06:37,420
You're going to get more phase cancellation. Oh.

98
00:06:37,420 --> 00:06:41,420
So technically, this is the correct side according to the maths.

99
00:06:41,420 --> 00:06:46,420
Because what you want to do is launch the sound that way it disperses within the room.

100
00:06:46,420 --> 00:06:50,420
It's coming out both sides. Oh, oh, oh.

101
00:06:50,420 --> 00:06:53,420
I get it now. It's the parallel port.

102
00:06:53,420 --> 00:06:58,420
I get what you're saying. Yes. Which means there should be spots when we're walking around on the sides when it should

103
00:06:58,420 --> 00:07:00,420
just cancel out and sound weird.

104
00:07:01,420 --> 00:07:04,420
It's not very bassy. It's not that bassy. What the hell is this?

105
00:07:04,420 --> 00:07:07,420
Let's find the right side of it.

106
00:07:07,420 --> 00:07:11,420
But you just walk around and it disappears. Yeah, it sounds like a Google Home.

107
00:07:11,420 --> 00:07:17,420
You see why these didn't really catch on? But I mean, if you built them into a bespoke environment, what if you could work?

108
00:07:17,420 --> 00:07:21,420
Yes. If you had a space designed specifically where you're trying to only get bass in one spot,

109
00:07:21,420 --> 00:07:28,420
that would work great for it. Which seems like a lot when you have other solutions, like just making a lot of space

110
00:07:28,420 --> 00:07:32,420
of other solutions, like just making a bigger subwoofer.

111
00:07:32,420 --> 00:07:36,420
But a true sign of a good subwoofer is how it integrates into an audio system.

112
00:07:36,420 --> 00:07:41,420
So DMS hooked us up with these amazing SVS Ultra Evolution.

113
00:07:41,420 --> 00:07:46,420
It sounds like a Goku type thing. It's basically the end game for a lot of speakers.

114
00:07:46,420 --> 00:07:51,420
These things are crazy. How we got like, what are these 8-inch drivers?

115
00:07:51,420 --> 00:07:54,420
Subwoofer, subwoofer, subwoofer, subwoofer.

116
00:07:54,420 --> 00:07:57,420
I think this will probably produce more bass than the tube does.

117
00:07:57,420 --> 00:08:01,420
Bro, don't tell me that. Don't tell me that. We spent so much time getting the tube.

118
00:08:03,420 --> 00:08:06,420
Okay, let's try it. We got the tower setup.

119
00:08:06,420 --> 00:08:10,420
We got the Bose acoustic wave cannon setup. Let's see how good it sounds.

120
00:08:14,420 --> 00:08:15,420
Okay, so...

121
00:08:19,420 --> 00:08:24,420
Yeah. What happens if we take out the bass cannon?

122
00:08:25,420 --> 00:08:27,420
My guess, not much.

123
00:08:29,420 --> 00:08:34,420
It's honestly just cleaner. Yeah. It's just cleaner. It's a little bit less boominess.

124
00:08:34,420 --> 00:08:37,420
Maybe... No, it's just better. Yeah, it's just better.

125
00:08:37,420 --> 00:08:40,420
It just sounds better. I feel like a f***ing idiot.

126
00:08:42,420 --> 00:08:47,420
Our suffering is other people's. I was so excited about this bass cannon.

127
00:08:47,420 --> 00:08:51,420
And it's garbage. Honestly, the tube is still a little bit better than I thought it would be.

128
00:08:51,420 --> 00:08:53,420
Really? Yeah.

129
00:08:54,420 --> 00:08:57,420
Speakers weren't that good in the 80s. I feel like everyone's talking about like,

130
00:08:57,420 --> 00:09:00,420
oh, my dad's like 70s hi-fi speakers are so good. Yeah.

131
00:09:00,420 --> 00:09:08,420
But 70s hi-fi, in most cases, the vast majority of cases is not nearly as good as like $100 modern speakers on Amazon.

132
00:09:08,420 --> 00:09:12,420
But generally speaking, things were not very progressed acoustically in the 80s.

133
00:09:12,420 --> 00:09:16,420
Dad, don't watch this. They're not that good.

134
00:09:16,420 --> 00:09:21,420
You haven't written it yet, but I heard your comments. You're saying, why would they test that subwoofer in a big warehouse?

135
00:09:21,420 --> 00:09:25,420
It's not even like a good use case for it. So we decided to bring it to the lounge,

136
00:09:25,420 --> 00:09:30,420
where it's a more normal sized space

137
00:09:30,420 --> 00:09:33,420
and probably something that's kind of relevant to this actual use case.

138
00:09:33,420 --> 00:09:38,420
Probably a pretty big room for a house, but a reasonable size for a community space.

139
00:09:38,420 --> 00:09:41,420
So we think that this is a more fair representation.

140
00:09:41,420 --> 00:09:44,420
This is a 88 inch TV. It's a lot of TV.

141
00:09:44,420 --> 00:09:49,420
And look at how big the tube is. It looks like almost two of that TV.

142
00:09:49,420 --> 00:09:53,420
It's so stupid. Okay, but let's hear how it sounds. Let's play.

143
00:09:53,420 --> 00:09:56,420
All right, we're not here for the TV. I have no idea how loud this is.

144
00:10:01,420 --> 00:10:03,420
Can I give it more juice?

145
00:10:06,420 --> 00:10:10,420
It sounds a lot better in here. Yeah, significantly so.

146
00:10:10,420 --> 00:10:15,420
I don't think that it can pressurize that warehouse, but in a room of this size, I mean, it works.

147
00:10:15,420 --> 00:10:20,420
But it doesn't really have like a lot of like rumble. Like it felt like I could hear bass,

148
00:10:20,420 --> 00:10:24,420
but I wasn't feeling it. It sounds more like a woofer than a subwoofer.

149
00:10:24,420 --> 00:10:29,420
I would say even in a room this size, it's a bit cumbersome still.

150
00:10:29,420 --> 00:10:32,420
Do you want to compare it to like a normal sub?

151
00:10:32,420 --> 00:10:35,420
We're now listening on the 10 inch Mackie sub.

152
00:10:39,420 --> 00:10:43,420
So funny enough, the wave cannon actually did sound a little bit deeper.

153
00:10:43,420 --> 00:10:48,420
Yeah, I was thinking that. I think the Mackie sounded tighter.

154
00:10:48,420 --> 00:10:54,420
I do think as a whole, the Mackie sounds better to me. Yeah, but I felt like I got more of the bass experience from the cannon here.

155
00:10:54,420 --> 00:10:59,420
Yeah, surprising. I mean, again, this is a 12 inch woofer.

156
00:10:59,420 --> 00:11:07,420
That's a 10 inch woofer. A 10 inch woofer in like a one foot box versus a 12 inch woofer in a 14 foot tube.

157
00:11:07,420 --> 00:11:14,420
So like they both have their strengths. Would I say that it would make sense to implement this 12 inch 15 or 12 foot long

158
00:11:14,420 --> 00:11:17,420
12 inch subwoofer versus that tiny compact 10 inch?

159
00:11:17,420 --> 00:11:20,420
Absolutely not. There's no deployment where I would be like,

160
00:11:20,420 --> 00:11:23,420
like if you really needed to just get another one of those. Yeah.

161
00:11:23,420 --> 00:11:27,420
And the situations where these were manufactured for where you would like stack them,

162
00:11:27,420 --> 00:11:30,420
that might actually do some cool stuff. Yeah.

163
00:11:30,420 --> 00:11:35,420
But for the amount of space it takes up and how much it would have cost at the time.

164
00:11:35,420 --> 00:11:41,420
Let's go back to Labs and compare this against another subwoofer.

165
00:11:41,420 --> 00:11:46,420
This is the SVS PB17 Ultra Evolution.

166
00:11:46,420 --> 00:11:49,420
Holy s***. It's insane.

167
00:11:49,420 --> 00:11:52,420
It is. It's like even tapping on it. Listen.

168
00:11:54,420 --> 00:11:57,420
It's like the size of a mini fridge. Yes.

169
00:11:57,420 --> 00:12:00,420
These are about 165 pounds a piece and 6,000 watts.

170
00:12:00,420 --> 00:12:06,420
And we have two of them. So these have a 17 inch woofer whereas this thing only had a 12 inch woofer.

171
00:12:06,420 --> 00:12:10,420
Yes. And the magnets on these things go back to like here.

172
00:12:10,420 --> 00:12:15,420
That's... It doesn't. It's hard to do justice to the scale of this thing.

173
00:12:15,420 --> 00:12:20,420
Here's a 10 inch subwoofer for scale. And this is what we would call like a pretty good subwoofer.

174
00:12:20,420 --> 00:12:23,420
Yeah, that's pretty beefy. You want enough bass to fight God.

175
00:12:23,420 --> 00:12:25,420
I want to hear this. We got to hear it.

176
00:12:32,420 --> 00:12:35,420
It sounds terrible.

177
00:12:35,420 --> 00:12:37,420
It's so much bass.

178
00:12:38,420 --> 00:12:40,420
It's at half. Yeah.

179
00:12:42,420 --> 00:12:48,420
It's at half. For reference, the speakers are all the way over there pointing in a different direction.

180
00:12:48,420 --> 00:12:54,420
And this is causing the robotic ARM to sense force.

181
00:12:56,420 --> 00:12:58,420
Holy crap.

182
00:12:59,420 --> 00:13:02,420
Oh my God.

183
00:13:10,420 --> 00:13:11,420
Yeah.

184
00:13:14,420 --> 00:13:22,420
Holy s***. That was like the whole building like the AC and the LED wall.

185
00:13:23,420 --> 00:13:26,420
Yes. Come into those two things.

186
00:13:26,420 --> 00:13:30,420
I've seen people put four of these in their houses before.

187
00:13:30,420 --> 00:13:33,420
This is crazy. It's so much.

188
00:13:33,420 --> 00:13:35,420
It feels like a theater. Yeah.

189
00:13:38,420 --> 00:13:41,420
I like how this video was supposed to be about this Bose acoustic wave cannon,

190
00:13:41,420 --> 00:13:44,420
but it ended up just being like, wow, look at these SVS subs. Yeah.

191
00:13:44,420 --> 00:13:48,420
And realistically, again, I don't think anybody needs this specifically.

192
00:13:48,420 --> 00:13:53,420
I feel like someone could get by just fine with like a $400 SVS sub and that would be insane.

193
00:13:53,420 --> 00:13:59,420
Yeah. They probably need these SVS subs about as badly as they need the acoustic wave cannon system.

194
00:13:59,420 --> 00:14:02,420
Yes. So in that sense, this is almost the perfect comparison.

195
00:14:02,420 --> 00:14:09,420
It really is. They're both needless and you can probably satisfy anything that you need with a very,

196
00:14:09,420 --> 00:14:13,420
very affordable and effective option.

197
00:14:13,420 --> 00:14:17,420
Actually, we'll have some good subwoofer recommendations from DMS himself down linked below.

198
00:14:17,420 --> 00:14:20,420
But if you wanted to go absolutely insane with it.

199
00:14:20,420 --> 00:14:23,420
No better way. This is the way. Yeah.

200
00:14:23,420 --> 00:14:26,420
Skip the tube, get the 17 inch subs. Yep.

201
00:14:26,420 --> 00:14:31,420
Slap these in a home theater, run them at a very low volume to protect what little hearing

202
00:14:31,420 --> 00:14:37,420
you're going to have left after like one movie. I wonder how much productivity we've destroyed today in Labs since they're like,

203
00:14:37,420 --> 00:14:40,420
Listen. Right there. I warned them.

204
00:14:40,420 --> 00:14:43,420
Just to give the candidate a fair of a chance as I possibly could, I set up a low pass filter

205
00:14:43,420 --> 00:14:49,420
and then did some DSP tuning by ear to try and match what they're doing with this guy.

206
00:14:49,420 --> 00:14:53,420
It's not going to be perfect, but honestly, it's a big improvement of where we were at.

207
00:14:53,420 --> 00:14:58,420
I don't know exactly what sort of DSP curve they're applying here, but if I had to guess,

208
00:14:58,420 --> 00:15:02,420
it's probably close to what I just did digitally. Yeah, I can like feel the pressure in my ears.

209
00:15:02,420 --> 00:15:08,420
I don't like feel it though. That's a base tube.

210
00:15:08,420 --> 00:15:11,420
That's base tube.

211
00:15:11,420 --> 00:15:15,420
That's all I got. Thanks for watching this video. Thanks to DMS for coming out and helping us out.

212
00:15:15,420 --> 00:15:22,420
And thanks to SVS for sending over those speakers. And if you liked this video, why don't you check out the fire truck that we put some crazy subs in there,

213
00:15:22,420 --> 00:15:26,420
give it a whole sound system upgrade. Now that truck is fire.

214
00:15:26,420 --> 00:15:30,420
That joke was probably made in the video. I probably am not the first one to make that.

215
00:15:30,420 --> 00:15:33,420
That's pretty good though. I know it is good. Joke's so nice we made it twice.
