As a 35year mechanical engineer, I approve this explanation. Just the right amount of technical details. 👍🏼✌🏼

Knowledge not shared is wasted. Thank you for sharing your skills and knowledge. I could listen all day 😁

I didn't understand a single thing, yet I'm amazed and loved the video

Wow, that is easily the best and most informative audio video I've seen on here. From the top quality info to the well made graphics. This man knows his trade.

Holy shit. I feel like I just had a 1 hour lecture in 7 minutes. Lots of great information. Looking forward more of these informative videos. Thanks for sharing & keep it up. To take things a step further, some math formulas or guiding principles to help out with designing enclosures would be greatly appreciated.

Was waiting for him to either open his eyes or play the keyboard the whole time. Just had an idea for a speaker box design though so I thank you very much.

Your knowledge and experience is priceless 👍. And you explain everything in a professional manner 🤘

I have commented before and I will again, this is the guy to listen to and watch. I am also a guy who knows this subject matter for many years oh, so I can tell you for a fact that this guy is good. The level and execution in which he explains things is superb. He doesn't just recycle and regenerate the same generic stuff over and over as do most of the videos on audio. I also respect that he said that he is still learning, because that shows intelligence instead of arrogance. I have over 20 years experience myself, including a MECP, and I'm also always learning new things. I like watching his videos for these reasons and or even just to touch up on a few things. Then again when I'm out in the shop, I'd rather watch this type of thing then Keeping Up with the Kardashians or some nonsense.

That was a pure masterclass. Full respect and thank you.

Simply AWSOME!! Yes finally a guy that explain very well in deep the accoustic theory!!! A big thanks from Doctorbass, Canada

Awesome, glad you're still making videos Pete!

Your gonna go a long way my friend, keep doing your thing. knowledge is key

This is some gold right here. Thank you for sharing! Now I understand why I personally like round ports better than a slot port

Fabulous! I read up on all this stuff 30 years ago and I'm very rusty, this is getting my brain back up to speed fast - thank you!

I have been researching this for weeks and this has tied everything together into one neat explanation that I finally understand. Thanks.

This is an excellent example of how to produce a quality educational video which is extremely time efficient & to the point yet still entertaining. Top marks.

Such technical info with a dash of comic relief is always welcome and/or gives me something to comment upon. So, thanks for that and keep it up! 😊

Why did I just find you now. It is so nice to see videos on these subject with people who have real knowledge. I would like to start building speakers as a hobby and you answered allot of questions I had. But made me aware of allot of thing I didn’t know existed. Thank.

I am so grateful that I stumbled on to your channel. I first got interested in speaker enclosures back in the 80's. It soon become a passion. I lost that passion in the 90's but since hearing you it's been resparked. Keep the information coming.

I think I never subscribed to someone this fast! The knowledge you have and the way you present it is really nice.

I missed your videos for a while now. Glad I found your channel again!

You just made something that so many people dont understand so simple, ive tried so many ways to explain why some ports need to be there and they still dont understand. Thankyou for make it so much simpler.

Usually, when I see the name of video "The BEST Video EVER" immediately I change the channel, but this time it was a good video. The really good one Thanks

I like high info density videos like this, no drawn out introductions and repeating over and over or product placements. Greatly appreciated! 7 minutes well spent!

Watched this 3 years ago when I first started making boxes and kinda understood it but bow I feel this the only man I can listen too to reassure myself I’m doing everything right 😂😂

Please never stop talking! and thank you for these lectures!

Learned more about vents from this one video than in the last 20 vent-related videos! I'm building my 'first' set of speakers from the ground up, this video has helped my progress immensely. Thank you! 👍

Thank you so much for your insight!

Very informative as usual Pete. I have learned alot over the years from your videos. Keep them coming.

Hell iv been in this for over 40yrs. And i still learn something all the time!!

I’ve never commented on any video on UKposts... I felt you deserved to know that this video and several other videos you’ve made are providing information that I have spent months searching for. Thank you, extremely impressive video, and awesome teaching method. I’m currently building boxes for 2 Fischer midrange home audio speakers... almost have all the info I need..

your videos are the best! Glad you're making them still

Thanks again for another great guide to more info to figure out for my own builds.

I love your explanations, you cover horn theory so well.

i saw this video 4 yrs ago. good to see it come back across my page.

Fascinating stuff! I would really appreciate if you made some more videos like this explaining the fundamental operation of enclosures and speakers. I'm interested in acoustic design and your content so far has been very helpful. Cheers!

Love that studio. So neat and tidy.

Wow. Finally someone that knows what they’re talking about. That was awesome. Thank you.

Good job as always sir. Clean and to the point- killer graphics.

I love seeing someone who knows what they are doing. Cheers.

Thanks for all the knowledge!!

i agree it was well conducted he said what we wanted and done. no drawn out talk until we fall asleep kind of video

Your presentation was short and concise. Brilliant explanation! Loved it!!! = )

no idea how this ended up in my top recommended but I've never learned so much about something in 7 minutes.

Man you have the most informative channel on speakers in all of UKposts. Bar none! Thanks for doing what you do.

Wow ... your fantastic at presenting , editing , explaining , etc etc and your knowledge is just . Wow .

Finally, someone that can translate knowledge very very well into a concise and informative video. Well done Sir, and thanks.

Stumbled upon your channel, finally i can learn something new after decades of loudspeaker building/interest! Thanks for your effort in making these videos! +1sub

Wow, awesome stuff here. I definitely subscribed. Would you be able to make a video on the basics of how to build a subwoofer enclosure? :) For example: A driver with these specifications + These expectations in terms of frequency response and application = This is how to design the best enclosure. Because when i look around, i can find tutorials or guides but it's just like, you have these specifications, run it through this program and there it is. But i want to know why we choose a port width, length, box size, ... So i can take that knowledge to the next project. I think i understand the basics, however it's sometimes very confusing. But for some reason i immediately understand everything you explain.

And this is why you’re the ONLY person I hire to design my enclosures! These other so called designers can’t even go into depth of why they send out what they sale to people!

I'm glad you said this, I've been trying to explain this to people for years. I even use the example of car exhaust systems. There is a reason that they are round. Regardless, you are one of the very few people that I have seen say this about round ports versus Square or rectangular.

great amount of knowledge, definitely enjoy, please don't stop

Love this!!! So MUCH knowledge dropped!

I love your video's great job at explaining your knowledge in different areas of audio. Great work looking forward to watching future vids.

It was a little funny the second time... Haha! Great content. I've also been in the hobby for 15-20 years and I'm still learning. Love it.

Awesome video as always,, looking forward to more explanation about this subject. I learn a lot every time I watch one of the vids - Love it

This was very helpful thanks for making this video.

Man, thank you! I know absolutely nothing about audio, but I'm trying to learn and you help a lot.

Fantastic concise info! Thank you!

Man you are very knowledgeable sir. I'm still in the beginning stages but trying to lessen and your videos are very informative and most importantly accurate info. I really wish I could get a box designed and built by you lol!

Thanks! Concise and compact for thought!

Videos I watch for information I'll typically play at 1.5 to 2x just because of general inefficiency in presentation). Your pace and script is perfect! Its obvious you're teaching something you know very well. Subd!

I look forward to your videos. Very informative

appreciate so much sharing the info there is so.much to learn

Flared round vent/ports are the best way to go. Just common sense in a way. Here is another way to look at it, for the most part, car exhaust pipes are round for the same reason. Most may not know this but a cars exhaust, length & diameter, also play apart in tuning the engine. And just like looking for a specific tuning frequency of a speaker box, you are essentially doing the same with an engine. This is also why sticking the largest diameter or shortest length pipe MAY NOT always be optimal for a specific build. Regardless this is why I follow this guy, because I am experienced in this field, got my MECP, & other certifications in the mid 90's, not to mention as much experience in building high performance engines & high end fabrications, & so I can confirm that this guy knows what he is talking about. One of the best actually, so pay attention to what he says, because he is on point

Thank you for your knowledge, mush appreciated...

Cheers for sharing boss

Very informative and quite intense. I would like to hear more about shape selection for a build. Because the box design programs only give you a port length based on the selected radius entered (therefore a round port is assumed).

i love your vids dude . thank you

Excellent video.

The most informative 3 minutes ever. Thank you very much

Superb explanation. Thanks!

Why are you so smart. I mean, I know basics of car audio, and some things that even installers don't know, but this is over the top. Your good.

Your videos are awesome! Thanks for sharing this knowledge.

Thanks bro

I absolutely love your content because I can tell you truly are an expert on the matter. I got into your channel because of the 3D printed enclosure for the 3" sub, and it got me hooked on it. But as a complete casual in sound engineering, your videos seem to be curated towards other sound engineers. I have watched the breakdowns and tried to absorb and research as much as I can, but that only gets me so far, since I already have very limited knowledge on the subject. One thing your videos really could use is ELI5 sections, where you dumb down what the subject means and how the variations of the subject affect the end user. Maybe a beginner series in sound engineering could do well? Either way I'm eager to learn more about this, and will definitely watch in the future. Thanks for the hard work!

Great stuff.

This dude does not fuck around. Instant sub. I'll agree with what someone else said, I also feel like I just got a highly condensed lecture with no bullshit filler. Amazing video.

Awesome bro. Another gem

Came here by "accident" but was captured by Your clear and knowledgeable presentation of a subject I didn't even think could interest me. Once again confirming my hypothesis that anything can be made understandable and interesting if it´s presented and explained "the right way". Thanks a million for taking the time and effort of sharing Your knowledge in such an excellent way. Best regards.

this was awesome

Thankyou for this vid I wish I was more knowledgeable on the subject keep up the great work God bless😊👍👍👌👌👌👌

That moment when you know more than anyone you have ever met..then feel like a complete noob hearing someone else explain something..20 years of audio engineering and while I understand all this, I could never explain it to someone else this well. Awesome.

Best video on this topic in a long time!

Brother, Youre the fucking man. Not a single youtuber has gone into this topic as in depth as you have. Thanks you so much

Thank you for sharing your knowledge and skills keep up.

Well done

Give this man a proper round of applause - he clearly is an expert on ports.

Liked and subbed, I can't wait to go through more of your vids.

thanks man

Thanks for some awesome content. I also noticed a few interesting questions in the comments, so I hope some of those will be answered in future videos. Nevertheless, awesome content so far. Subscribed after seeing the 1st video. Please keep it up. 👍👍👍

Liked and subbed. This is very useful. Thank you.

Thanks a lot mate !!!!

"Took me 20yrs & I'm still learning." Thats a true audiophile. If actively seeking out new knowledge, insight, & data ISN'T where the bulk of your time 'doing audio' is spent then you're not an audiophile. Sorry but it's tru.

Just came across this video and I enjoyed it. I will have to look for some more recent ones. A lot of information touched on here. It is apparent from your comments that you know a lot about ports and wave guides. I am hoping you have more videos that expand upon this topic. I have been designing and building speakers off and on for at least 30 years now and the last one was my first attempt at a transmission line. I think I’m in love! It was a difficult design and build that involved a fair bit of tweaking but it turned out great (in my opinion). That was the last speakers I built (about 15 years ago). Still enjoying them but now that I am retired I want to built a larger pair. I am worried that I may has just gotten lucky last time and may not be as successful this time. Thanks for your entertaining video.

Wow, exact and concise and easy to understand! Please do a video on transmission line enclosures for the mobile environment

This is awesome! thank you for sharing your knowledge and experience. Could you do a vid that explains how these variations affect how a speaker sounds (with different types of music, etc.)?

Great video, well presented and illustrated. Had to watch it twice as I’m new to this game. But feel I’ve learnt a lot.

Youre a god damn legend, thank you

great and solid base to build upon...
