See the build article for more details on the design of this sub woofer: ibuildit.ca/projects/making-a-powered-sub-woofer/ The soundbar build: th-cam.com/video/25rjfeoKhW4/w-d-xo.html
Port area is too small if you are going to power it over 20W below 40Hz. The port will cause chuffing, especualll in dynamic movie scenes. Ive recently built a portable bluetooth speaker with 2 6.5inch woofers (xmax of only 9mm), I used a 110mm (little over 4 inch)port tuned to 36Hz and below 40hz and over 80W of power you can hear the port slightly. (Which is ok, since the portable amp will only be 100W) Small narrow ports also make the port more prone to port noise. I would go over a 5 to 1 ratio (width to height), unless the port is at least 25% larger then necessary. WinIsd is a great free program for modeling drivers under power.
@@epiphonesg007 I agree, the port is too narrow. That's why most ports you see are circles or squares. You can even make triangular shaped dual ports in each of the bottom corners. In most speaker design programs, you can play around with the size of the port, and the length of the port, and the number of ports, to find something that works well.
I'm 67, and watching this makes my blood pressure go down (I suffer from hypertension). I've done many things in my lifetime, but building a set of speakers or a subwoofer is something I've always wanted to do. I really enjoyed your video and soon plan to make an attempt at building something I can be proud of. Well Done John.
After working with wood for a year at work in pattern shop, Some people will never have any idea how much skill and patience this man must have to build all of the things he does. Much respect my friend. Keep making cool vids for me to watch and never do. Lol
Not that I'm surprised with you building a speaker, but it's cool you've incorporated other things into your 'woodworking'. Your soundbar was great and this sub is a great compliment to it. I know you've done a PC case, but I'd watch other wooden PC builds if you're so inclined.
Very cool. Your speaker building videos are some of my favorites. I even read the build article this time because I was curious about the enclosure design.
This came out awesome. The osb was a great choice I think. I also think the towel texture complimented it well, but understand if you want it smooth. Awesome project.
Nice job. You're pretty good with that table saw. Heck with the people that thumbs down. I think it's great that you're able to do something like that and that you put it on a video. Keep up the good work. Boom
I used OSB years ago for a set of 3-way large bookshelf speakers finished them with polyurethane. Loved the look and only parted with them after being offered way more than I had in them.
The speaker is awesome , but please remove the fiberglass insulation and vacuum clean the inside. That insulation throws small glass particles in the air impossible to see in most lightings conditions , people can breath that in, and it is dangerous. Sudwoofers move a lot of air in and out of ported enclosures , that's why is not a good idea to put that type insulation in there.
I don't think anyone has any delusions about John being an authority for safety. Hell, watching the clip at 3:12 I'm amazed that this guy still has all of his digits.
That’s pretty awesome, I found out the hard way about paint marking while it’s still soft. Takes about 3 weeks for it to properly toughen, until then polycell foam is the only safe contact material.
Very cool. Nice use of old material. Not very many people consider options such as that. I've been wanting to get some Baltic Birch and cut it into 1" straps then glue them back together face to face so the edges now become the grain pattern. Then shoot them with clear only. Down side...I currently have no use for such an idea.
Another great build😊 Mine I cheated by scavenging an old Grundig bass unit modding it and renovating the main exterior and now matches in with the surround sound bar next to the Samsung 55inc tv 😊 sounds awesome with real growl 👀 For those not in the know, make sure your inputs are correct 👍ALSO a lot of surround sound speakers are 6 OHM - connection to an amp with 8 ohm outputs may damage the speakers OR the amp unit! IF the outputs are 4 ohm connecting 6 or 8 ohm speakers is usually OK 🆗 Love your vids and awesome workshop

Is the new poly urethane construction adhesive a different flavor than the old one?

I love it! Grandpa builds a large subwoofer and gets revenge on the young bass-heads driving by every day!
You really dont have to mider all the edges no one will ever see. He is just showing off. Lol
@@Ericdawg420 If you really want to create something beautiful, sometimes you just have to put that finishing touch on it to make it special.
Wow 67, and want to build your on speakers. Do it! I'm really impressed by your mentality.
Can really recommend it, i built a subwoffer system for my living room, inclosed is the easiest version if you are a beginner.

Dont use fiberglass to stuff the subwoofer. The fibers will be blown out and airborne into the air you breathe.
Wrapping the fiberglass in t-shirt material will stop this from happening. Or you could just use polyester fiberfill instead.
@@Grommet2007 surely polyester fiberfill
Snag a few old pillows, wash em and rip the stuffing out. Or buy new.
Everyone who did this that read the comment just died inside
I'm allergic to fiberglass, I stay the fuck away from that stuff.
I really like your comments during the movie John -- They are well composed and with a certain "calmness." . You´ve got a new fan in Denmark.
I would have never thought OSB could look so good. But then, you seem to make it work over and over again.
The contrast in color and materials is a nice touch.
With OSB, you either love it or hate it. I love it. I made a gift for a friend and their response was, "This is great. I will paint it right away!"
Greetings from the South Coast of England. Love your videos John. Thank you.
The precision of your builds is just a joy to watch and admire.
Great editing John. I dig the machine gun brad nailing. Kudos.
I love your home made bar clamps!
Like your channel because it's kinda non traditional wood working. Interesting to see the engineering behind what you do.
This was a lot of fun to watch. Never seen a port like that, really interesting!
This is nice. I just built a 21" subwoofer. Super fun stuff.
Not that I'm surprised with you building a speaker, but it's cool you've incorporated other things into your 'woodworking'. Your soundbar was great and this sub is a great compliment to it. I know you've done a PC case, but I'd watch other wooden PC builds if you're so inclined.
I do indeed admire this build here, the OSB makes it kinda unique.
The OSB looks really tidy in this application!!
One hell of a craftsman at work here.
You might have got used to it by now, but I absolutely love that table saw John. Looks like a real pleasure to use.
I was going to say the same thing! I wish I could buy his table saw over the vast majority of the ones for sale today.
Same same.. it looks so easy to use... I came here for the saw :D
@@vgullotta he has plans that you can buy to build it
Subwoofer in action is one of the beautiful things to hear !
Nice description of the procedure, easy to follow and understand. Great woodworking skills!
The magnet on the speaker is disproportionately enormous!
Somehow you made OSB beautiful
Very cool. Your speaker building videos are some of my favorites. I even read the build article this time because I was curious about the enclosure design.
Nice contrast between the osb and the black front panel! Nice design and build. Great work John!
Whoa I Love It! The front black and textured wood sides look really unique, but still professional together. Great Video!!
Great woodworking skills. I do not like the way OSB looks but, it makes for a "dead" cabinet along with liquid nails type adhesives.
Nice little sub.
Beautiful sub woofer build John!. Are the neighbours satisfied aswell?
John, your creativity and knowledge/experience in both design and execution always expands my own thinking box.
Thank you Sir.
Nice box
The table saw is a beauty.
I got exhausted just watching this. No wonder I'm putting off my upcoming monster build.
This came out awesome. The osb was a great choice I think. I also think the towel texture complimented it well, but understand if you want it smooth. Awesome project.
Your skills with timber are quite something
I LOVE IT!!!
The lack of a push stick gives me an anxiety attack 😂
Skills to pay the bills! Fascinating watching you work.. informative narration too. Great work 👍
Watching you glue those perfectly mitered panels together was cathartic.
I love this speaker so much 🥰🥰
wish I had a workshop like this damn nice job
Thank you for the tips for making Speakers and Subwoofer yourself.
What a beatifull work!!The result it’s amazing!Congrats
Beautiful work John!!!!!!!!!!!
I really like tasteful use of OSB in modern builds like this - Super nice final product, thank you :D
nice build John looks like your going to rock your house out with that sub also I really like how your table saw came out so clean
I really like the industrial look of that construction panels.
Nice Job John 👍❤️
We use poly fill in subwoofer boxes in car audio. Its cheap an does a great job.
Except in sealed enclosures where fiberglass is SIGNIFICANTLY better.
Nice craftsmanship. Well done.
Nice job. You're pretty good with that table saw. Heck with the people that thumbs down. I think it's great that you're able to do something like that and that you put it on a video. Keep up the good work. Boom
Love that Boston shirt. I’m 12 and I love that kind of music great build!
“Heisz” sounds like cool brand name for hifi speaker company :)
Totally maaan! 😂🔥

Your seriously talanted bro!!!
CLEVER use of forbidden osb! NICE
Looks and sounds great John

@@F3Ibane haha... I noticed that too...
Love the concept. Just wish you woulda used a 15" woofer or if you're feeling crazy an 18-incher woulda been killer!!
Thanks for uploading.
I like the look of the OSB. Great looking box
Turned out great. Fun project to watch. More off that plz
Looks good John. Nice work.
That’s pretty awesome, I found out the hard way about paint marking while it’s still soft. Takes about 3 weeks for it to properly toughen, until then polycell foam is the only safe contact material.
I have a feeling this guy got a A+ in woodshop.
amazing work. looks great
That saw sounds so smooth!
Pretty nicely done, and nice you have reused materials!
Very skillfully made, with a lot of passion.
I actually like how the towel made the paint look it looks kind of similar to what barefoot does to their pro speakers
Looks great 👍
This is masterclass.
I appreciate that we get to see like every single nail go in at high speed
Awesome work...👍
Thats a really good looking speaker, wish i could make one at home
Gym floor sealant on OSB seems to work well to provide a very scratch and flake resistant surface. But can take some time to dry.
Impressive build Sir! 👍
I am so jealous of that beautiful table saw
Mitered osb looks cool!
Thanks John great videos
Awesome work John! 😃👍🏻👊🏻
I'm really digging the smooth black front and OSB sides. Nice combination!
sounds awesome
Very instructive, thanks John !
Very Nice work!
Great build ! Love it ! Nice Tools !
Nice subwoofer box ...but those table saw handle's 🤤 they made me subscribe. 😆
wow good wood job very nice.!
another german is impressed
Professional!!! Goooood!!!!
Very professional
Thanks from Fontana Ca 👍🏽
Nice build John. I really like the use of OSB for the outside cabinet.
great article John. well done.
Looking good!
Appreciate all the precise, beautiful joinery. Great looking subwoofer.
Nice build John! I like the OSB and black combo.
Very cool. Nice use of old material. Not very many people consider options such as that.

one of the best speaker i saw youtube, very professional and complete detail
Very nice build, and as always, high quality videoproduction.
