Things you didn't realize about bass... until now.

Devin and Austin explore bass reflex designs with slow-motion footage, as well as acoustic nozzles, advanced cardioid configurations, V-shaped phase-shifting slotted ports and just have a whole lot of fun. Grab your headphones and strap in!

Thanks to PA of the Day for their support.

Actually I did realize this and more. Your clickbait title is a bit arrogant. Your viewers are smarter than you think.

[SuperChewy]

I’m from an era when it wasn’t as easy as watching a video or perusing the internet for info, what you showed was knowledge that I learned from quite a few years of reading and research. Quite informative and loved every minute of it.

[Daijyobanai]

All clearly explained for us who aren't sound engineers, just an average hi-fi enthusiast here learning something new.
It's impressive just how directional that big bass cabinet is, and the science around making it work is fascinating, same for the 2 cans being moved closer and further apart. Thumbs up!

Hello this content should be taught to all sound technicians! It is very educational

[no_bull]

Bass frequencies are a science subject on their own! Excellent video.

I have been into home theater for 20 years and have built various vented subs, but I never knew about the pressure waves from the port changing direction with relation to the driver. Thank you for sharing this knowledge and taking the time to present it in such a straightforward, yet entertaining way.

I feel like this dude walked to the street and found the first guy and offered him $20 to stand there for 10 minutes. Then I started to watch another video and same with that one. 😂

At around the 6:06 mark that "jet engine" shape is called a "venturi".
Like a naturally aspirated carburator. Helps low pressure rush to high pressure uniformly.

I've designed a lot of speakers, including some with pretty esoteric radiation patterns. This is an incredible demo of large room /outdoor bass management, and the explanation of the vent resonance was incredible. Really impressive.

[loveDRAGONCON]

this is important work. thank you for demonstrating. Its not about how much you understand the graphs and or how to specifically tune them perfectly. But at least opening the public up to how the acoustics, phase and placement matter for sound.

[Rylan-zy]

You did an amazing job teaching a topic so many take for granted! As a rookie going into bass systems and building this really opened my eyes to how bass works, I've watched so much videos about bass but this video? It really takes the cake! Almost feels so illegal to watch a video this good! This is very helpful in understanding how bass works! A very sacred sound! Great video!

[jahn-pierrezietsman]

This is the best reprasentation that I have ever seen about subwoofer tuning. If I could I would give this video a million likes I would!!!

This is the explanation I am looking for not available on any other speaker/audio related channel. Salute.

[colmanbaldwinson]

I really liked how straight cut and well articulated Devin delivered this video. I usually dont click on or expect to learn anything from "things you dont know about X" videos but this one was very good

[guywhite]

Now I understand what John Atkinson (Stereophile) means when he speaks of the driver at minimum motion at the tuning frequency of the enclosure. I could never envision this in my brain, but your demonstration makes it very apparent.

[ucheucheuche]

Thank you thank you thank you for playing the sound from the speakers. So many people drone on and talk about speakers, without demonstrating!! You rock!! 😆

[Trucker-Belly]

Don’t insult my cell phone! It has all the bass!😂😂

[ahsapmumbai]

In my opinion you are the only guy who has uploaded a video for these rare speakers.
You and I are the unique people who purchased them. Anyway
I am an engineer from India, bought this fantastic set of 2.1 with a passive diaphragm sub woofer. Nearly 20 years ago. I have a similar problem.
That thick cable with multiple wires originating from the small satellite speaker and going towards to the sub also develops a loose connection in the connector and starts making weird sounds intermittently, this section too needs to be looked into.
Your video is lucid and helpful thanks for your effort, greetings and best wishes from India

[phillipzx]

This was actually a very cool and informative video. I started working with PA systems in the early 80s and was positive I knew all I needed to know about subs. I learned something here today about subs I didn't know prior.

Thank you.

[EduardoGonzalez-fbjv]

this man so far has been the most knowledgeable and intellectual professor of sound design and engineering ive ever seen over YouTube.
i will learn from you everything there is from you.
