A tapped horn enclosure has to be my all time favorite designs for subwoofers. It just makes the most sense.
Also with the driver inverted so close to the port. You could wire directly to the driver. No need for a terminal cup. It actually provides more quality to the signal path.
MOST UNDERRATED CHANNEL ON YT, LITERALLY EVERY PROJECT YOU COME UP WITH IS INSANELY PRECISE AND EASY TO FOLLOW ALONG WITH, AND I MEAN THE EDITING IS ON A WHOLE DIFFERENT LEVEL! KEEP THESE PROJECTS COMING MAN I CAN'T GET ENOUGH OF EM
he is literally, a genius.
That is a perfect sized sub for most home applications. I could incorporate tactical toddler-proof chicken wire into the mouth of the horn & actually have A SPEAKER in my living room again! When aforementioned baby boy tippy-toed & touched the lower edge of the Fostex's surround, my Hexibase-designed main horns were whisked away at a frightening velocity; citing Space-X metrics. I believe the next mains will be twin 18" MTM dipoles, NATO-grade chicken wire defended, 30mm granite baffles & feet, built to withstand 9/11 grade, self-inflicted, insurance-claimed explosives; or an 18 month old.
Oh, Pete, I have a design request for a set of 80w LaVoce FSN041.00's.
That aside, we just got a new waverunner and a house almost 2 yrs ago. It's time yall took a vacation this spring or summer & visit for a break & some great food. Chat soon, hit me up on messenger or 3344006144.
Miss you both.
He’s the best
Seconded, you, project farm and big clive are some of my faves 👍
Even waaaaay back in his PWK box design days where he was in the desert with a little shack making boxes he was a genius and had awesome vids!
So amazed how a little subwoofer with the right box has such a huge output! I would absolutely love one of your boxes!😊
Cinematic camera shots like a Hollywood movie. Following your channel is super inspiring.
Low-end comes across just fine on the youtube, as long as I have my IEM's they can reproduce the low end, my computer speakers can not. Thank you for the demo.
@@HexiBase You are welcome, I think you really up your game with this production.
Nice work! Note that on a bass “horn” or waveguide, it’s not necessary to have smooth radiused turns. In fact, you want the turns to have sharp corners so that they act as low pass filters for the mid range and high frequencies from escaping the mouth of the horn. Smooth corners on waveguides only needed for mid range and up horns. So building with traditional flat sheets/panel construction will yield sharp corners and save on material waste. Assuming you want the sub to work below 100Hz, the characteristic wavelength of 100Hz sound waves is 3.4m long. So a sharp corner or a round corner of a few inches isn’t “seen” by the wave - it’s acoustically transparent at that frequency.
You won't get a response, but you can rest assured all that you mentioned was 3rd grade material for him. If it's there, it's been calculated, it may even be for esthetics alone, but it has been accounted for.
I would love to see him tackle a quarter wave theory inspired 4 inch sub, or paraflex. He is definitely far from conventional with any actual pro PA approach, however the videos are too fun and the results are neat
@@stevemilton3499 lol, sorry to dredge this reply back up. I guess you must be a fanboi? XRKAudio is 100% correct. I'm familiar with his posts and projects on DIYAUDIO; all of which are far in advance of hexibases skill level. Hexibase does OK and his projects get a fair bit of attention on youtube, but they are pretty gimmicky and cheap when it comes down to it, just as this one is.
@jeremyglover5541 reads a lot like it's coming from a fanboi.
@@stevemilton3499 nope. Just familiar with his work. Havent built any of his projects. I design my own amps/dacs/speakers. I dont build a lot of class A amps these days and mostly dsp driven active designs. Im a fan of science though and thats all he is talking. The features hes rounding over/smoothing etc are dealing with wavelengths that are larger physically, so they are effectively invisible.
Absolutely mind blowing amount of quality and patience!
Impressive output from a 4 inch driver. Thank you for pointing out the relevance of tapped Horn. I am in the process of building one. Cheers !!
You'll enjoy it. I built one with the Tang Band W6-1139SIF and it's money! You don't have to blast stuff to get great low bass.
@@androiduberalles great 👍
I always love eating breakfast to these videos from you. I have an idea for the worst enclosure material idea ever (or is it?...) Legos!All the parents have them laying around. Building a box on a true budget!
Vintage audio tech here. Great video. Beautiful construction. Just one observation, if I may. It's not a horn. It's a folded transmission line. That doesn't mean it's not a good bass cabinet, it's just not a horn. Horns are acoustic transformers that must follow a specific "flare rate" to work, and they tend to be quite large when called upon to work below a few hundred hertz. A true horn that is good to 30 Hz or so would be too big for one person to move.
There are those who argue that the cabin of a car works as a horn for bass, but that's not true. It does provide considerable "cabin gain" because it is a mostly-sealed box with dimensions smaller than the wavelengths of bass notes, so it acts as a constant-pressure environment. But that doesn't make it a horn.
Pete, you just simplified the Bose Acoustimass into a 1 driver, higher performance sub. I'm sitting her laughing, because not only did you do it simpler and better, but did it with 1 small driver!
Bose has some theories that could work, but they fail miserably in the execution..
Been a while! I literally just re-checked your channel yesterday for 3D printing speaker inspirations. Good to have you back with new ideas and video demos!
Same here man, there's something almost therapeutic about his content.
I was wondering where you'd gone too, but 24 days of cutting AFTER figuring out what the machine can do, plus assembly, finishing, testing, editing...
Also, thanks for the track names in the testing sequence!

@@HexiBase really looking forward to your videos and 💡
I could not push the 👍fast enough i really missed you content keep up the great work
Nice project, practical way to make big sound from a small speaker
Thank God. I was hoping you'd do a tapped horn video. Please consider doing an in-depth video on horn loading vs bass reflex and driver suitability to either. Your Yoda knowledge is much appreciated from 🇰🇪
Countryman. What shipping method do you use to get equipment like drivers? I got some things from parts express through kentex cargo and its taking too long. Thanks.
@@balladbuster5109 I haven't gotten stuff from parts express before but if it's from the US then kentex is my best bet so far. There are some somali shipping companies in Eastleigh that I want to try next. I think they're best for bulky shipping to make it worth it. Which I guess works well for multiple drivers. How long has it taken for shipping?
You got me at Tapped Horn. I’ve built several tapped horns for the Tang Band W6-1139SIF 6-1/2". In another life I built competition car audio systems and those systems seem sloppy and inefficient compared to what we can achieve with small drivers and tapped horns. The demos really conveyed how well that enclosure performs.
the low end on that thing is amazing
You have a great sense of humor.
Yooooooo. I get butterflies every time I see that you posted man.
The in-car response was very satisfying.
I built a tapped-horn sub using an Infinity Kappa Perfect 10". That driver/enclosure combo did more with 150 watts than I would have expected with 600 watts! Amazing. Thanks for sharing.
@@HexiBase many fortunes made and spent on that first watt!
Glad you’re still posting projects.
I think I finally figured out why I like your videos so much. You are exactly where I was supposed to be. Somewhere along the way I got lost, and I could never find my way to get to where I wanted to be. Didn't know how I didn't have the tools I didn't have the support. But it is what it is I'm happy for you and happy to watch your videos.
Man, I wish you still lived in AZ! After all these years your projects never cease to amaze me!
PS
Sound check was YES!!
Outstanding!
Impressive multipurpose enclosure
Water jet is what you want for plywood. No requirement for abrasive means the sapphire nozzles last basically forever.
lol, Dante and Randall, "you never go ass to mouth!"
Woah! Good thinking with the Harbor freight table!
I was just rewatching your 3D printed boxes and this came up! Good surprise
Sony WH-1000XM4 over Bluetooth on Galaxy Fold3. Absolutely incredible. The deepest base I can remember hearing over a RUclips video. Not an audiophile tho, so I don't know the terminology of the finer details to point out.
This is the sign of great installer/box builder/designer. When I first got into car audio back in the 80's I met an old audiophile who showed me that proper box design and build quality matters more than the amount of money you spend on subs. He could make cheap subs from Radio Shack sound just as good if not better than the name brands.
this was really job for an cnc mill, but appreciate the effort. Mind blowing results as always.
If this man put out a payed instructional course to learn how to do what he does I would pay for it.
Again, I like your tracks... super weird and ambient. Dig it.
From a car audio shop owner, it sounds great through my headphones!
love these projects, though i want to see another 3d printeds fancy t-line
Same here. An enclosure with either a larger single driver or multiple small drivers.
I know that enclosure size is dictated largely by the size of the printer. Wondering whether it’d be possible to print an enclosure in sections and well as the layers, and then combine the sections?
@@ScramTek not with rigidity
Long time, no see! Glad to see a video from you. They are always good.
Waiting isn't a problem - your videos always deliver!
Have thoroughly enjoyed these video and your channel. Your expertise spans across so many different disciplines thanks for sharing with us.
Always grab my Sony MX-1000XM3 headphones to watch your videos so I can appreciate the details. Incredible as always, thank you for sharing!
I'm listening with the AKG earbuds that come with the Samsung note 9, they still work amazing!! I can feel all the subfrequency nuances of that 4" driver enclosure in my jaw bone. Sounds/feels amazing, as always. Have been watching ya since the beginning!!
The production value in these videos is impeccable. Not to mention the impressive lessons I learn from watching. Kudos to your creativity, and thank you so much for sharing your experiments with the world!
I have a suggestion for a potential future project. Something that I've been looking for, but have been unable to find anywhere on RUclips or commercially available. A powerful subwoofer system designed for an electric vehicle; incredible focus on amplification, woofer, and enclosure efficiency. I have been a lifelong basshead, who has transitioned to an electric car. I miss the 25Hz "feel" of my last 12" 1ohm, large volume, ported enclosure... But I just can't see installing a system like this which I am sure will rapidly drain my battery. Anyway, just food for thought. I believe this is an incredibly overlooked market segment at this time and in the near future!!
Always enjoy your ideas with these builds. No need to apologize for the time it takes to get it right. You're pushing the limits of the drivers and your machines. Awesome video.
Thumbs up to this. I'd much rather quality over quantity. Release schedule of "When it's ready" yields much more polished content :)
Awesome little laser! Thanks for the vid!
does same or better than my under seat 10" sealed sub, design is everything
Just started working on a speaker project where a friend and I are repurposing an 11 inch bass amp speaker to play music out of.
After trying to do all the design and speaker magic this guy does by myself I have much more respect for him
Hidden Gem. Thanks for sharing. Creativity and Knowledge shared, we are blessed 🙏
Hi Pete, i know that your Hexibase vlog is no longer available, I would like to ask you to consider making it available once if i would glady watch it again, there were some audio projects in there that i enjoyed watching
Listening on some Sony WH-XB900N headphones, because I came online to check out some new release (D&B) .
All I can say is, high quality video as always, I appreciate the effort you put into these uploads!
Cool build!
I used a Tang Band W6-1139SIF 6-1/2" driver for my tapped horn build. It's really nice addition to my modest home theater. It plays nicely down to 25hz.
Did you build the one from volvotreter or another one?
@@androiduberalles It was inspired by the Insubnia, designed by lilmike over at avsforums. I'm in europe, so the anarchy drivers were not available to me easily.
The driver isn't a great replacement for the Insubnia, so I recalculated the horn in hornresp and made some adjustements to the build
Spring time is upon us. Time to make stuff! Your channel is fantastic; for ideas, and debunking old-school paradigms.
Cheers from Texas!
🤘😎🤘
That bass...if I had one word to describe it,it would be "visceral".
I used my Moondrop SSP IEMs to listen to the test tracks in this video
@@HexiBase Thank you!
They certainly aren't the best,but they're one of the nicer IEMs I've listened to imo within its price bracket (50 USD and under).
What's the title of the first test track??
I moved to the other side of the earth so it'll take me some time before I get back to audio crafts. However, I think a pair of something similar to Cyburg Needles with some Hexibase twist would be fun. Would be for me, atleast.
Anyways, keep up the good work, mate!
Cool horn design. I have two 38 hz "volvotreter" tapped horns in my main listening space.
I built a couple of those too. It really got me hooked on the tapped horn sound. It’s just so clean!
A sub that makes tons of bass with out the annoying boom!
I guess 4 inch's is enough depending on listening positions.
Nice to have you back. Enjoy your vids.
Dont know if anyone has typed it lately but your the MAN !
crazy a 4" woofer can have such long arms to reach deep like that.
Awesome video! Great extension from a 4 inch driver.
This is absolutely up my street. well done youtube algorithm! I'll be devouring the back catalogue soon!
Watching this in my house, with Infinity Interlude IL-40 towers and a Dayton Sub. This thing sounds very solid. Well done.
Aesthetically pleasing build to watch! Definitely an A for effort! We've come a long way since crafting an automotive sub enclosure ports with polyester and MDF back in the day!
Love what you come up with! That's impressive for a little 4"! I've printed your bookshelf design with the dual subwoofer box for a cool little 2.1 system.
So much good stuff in this video!
Great video with lots going on thanks for sharing.
LOVE the harbor freight benches for project spaces. Been using them for a few years!
Super cool as always
@@HexiBase Your musical tracks are great as well where could I find those
@@HexiBase OK thank you very much
You are seriously a huge inspiration. Your knowledge and capabilities in every field is just astonishing.
Very amazed by how you made this small sub sounded big. Tapped horn design is definitely the most efficient in terms of output. Watching here from Philippines.
The amount of work you put in these videos is amazing. But how about a CNC router next? Would be interesting and a lot faster. Or just more 3d printing, even better :)
But honestly, I would even watch you do some boiled eggs, bet you can make that look awesome, too.
@@HexiBase One for all, hope you incorporate every function in a design!
Shoutout to @William Osman. Miss you bro. Thanks HexiBase! Another great vid.
Prusa FTW! Love my MK3S+!
I love Base. I am happy that i have stumbled over your Channel.
Love your work. My grandfather built a bass transmission speaker system that had 12 inch paper cone woofers on a transmission line, it was way ahead of its time. I have always loved my sound and especially the science behind it. With subwoofers and bass and ever since seeing the Bose wave Radio alarm clock do its thing with its transmission line keep up with floor standing speakers I was set to do the same and now have a split level house where i have a massive area behind the back wall of my loungeroom to run a horn / transmission line woofer or subwoofer .. not just on a paper cone 12 inch which shook half the street, and btw your box and speaker sounds great, and well done getting that sound to play for us. My Horn / Transmission line will be based of a Paradigm Sub 25 Driver with an estimated transmission line length of 20 - 40 meters that transmission line is going to be a Basshorn style ontop (from memory 30hz needs 20+ meters before the wave completes, then 20hz 30 meters + i think?, people forget that bass needs to travel a good distance to complete the wave and to be able to "hear it" not "feel it" > it will be about 2 - 3 years till its done with this project but have the equipment ready expect all the MDF. Currently have a Paradigm SUB25 and got a spare SUB 25 driver only and fitted it in a ported comp box also. so 2 SUB 25's one with origional box and amp 3000 watts / 7000 watt peak Sealed and the one I put together, the SUB 25 Driver, in a massive Comp Ported box with a Velodyne SC1250 2500 watts / 5000 watt peak , the ported system is what I am going to do that project with. Your Video and the knowlegde you have was refreshing as alot of channels know how to make a SUB move and sure they get good kits to show off, but unlike yourself they don't understand some of the science and whats really important for good bass, your video makes me want to get th MDF and kick it off. 3000 watt 7000 watt Transmission Horn Bass Box, but the 5500 watts or 12000 watt peak of bass gets us by now. But your little Bass horn impresses me more, hats off.
This is just insane. Has insane response and output from a 4". One day id love to be this good!
Tom Danley is in fact the one who deserves credit for that.
@@PoloABD you should see the list of proprietary alignments he's designed, simply as a byproduct of a specific response request, using already purchased subs in less than desirable vehicle topologies. The great thing about his method is that alignment is not preconsidered, it's just a name or byproduct of what must happen to produce the target response.
I missed your videos so much bro. I would love to see you make a 12" 3d printed sub box and go to town with your ingenious brain. Because there are ton of great 12" drivers but not that many 10" ones. I really loved that 10" down firing one you did but I am planning on a home theater/music sub for home.
I watched this on my uconnect 5.0 in dash radio 7watts per channel. The speakers are kicker CSC693 92db sensitive. I have sound treated the doors installed acoustic foam wave guides and installed the same foam over dynamat to eliminate back waves.
I had the speakers running without amplification and without any crossover. I had my volume set at 18 out of 42 because at volume 20 there is bass roll off.
At volume 18 the kicker CSC693 3 way speakers were creating significant SPL reproducing your audio. My interior panels were moving in tune with your tapped horn. I could feel it in my chest. I believe I was feeding my speakers between 4 and 5 watts RMS each full range signal.
Impressive bass from that little speaker, thumbs up!
For Listening I used my Headphones from Bayerdynamics DT880pro (250Ohm)
That's impressive.! A 4 inch in a horn enclosure can do that.? Imagine something as big as a 10.
new mic setup seems a little... hollow? the laser looks pretty good but 7 HOURS per layer... you are a patient man.
@@HexiBase Next you will have to design some acoustic room treatment, thanks for the demo.
The effort show's the result... I know it takes time to plan, print, assemble/build, shoot and edit all these but mannnn.... Worth every second of waiting ❤️
Nice to see another video! I'll take quality over quantity any day. Hope you took some time away from work & videos over the course of the new year.
I'm constantly impressed by how much you can squeeze out of such tiny speakers! Thanks for educating and fun that you bring, it's always nice seeing you again ;)
It looks like you built a mini Jericho Horn👍 but tuned for bass. You should try building one.😉
wow your videos are simply AMAZING! all the time and effort put on these makes almost everything else in youtube just look lazy or cheap.
congrats!
and i do imagine how can you afford making videos like this one
Would this sub pair well with the design from your "Acoustic Puzzle" video? I need computer speakers, and I have a CNC router... (I would carve both designs from MDF, in two halves. Well, maybe 3 sections for this sub.)
Excellent project!! Bass was deep through my JBL earbuds.
I suggest using the laser to maker a template for cutting the pieces with a router next time. Much quicker for sure. Great vid:)
Using some JVC wireless earbuds. HA-A7T and the tapped horn sounds very nice. balanced smooth bass is what I got.
Your reviews are very thorough and instructive!
Great video as usual. To get a real appreciation, I usually listen to the sound clips through Bose headphones, and the sound quality is shockingly good, from these builds...
14:25 and 17:43 my favorite test track you have. Sooo good!
So much fun stuff around your house :D
Thank you Sir! My current setup is a denon x250bt paired to a set of psb alpha lr1 + subzero subzero i powered sub. Not the sharpest tool in the shed but it keeps a simple man like me more than satisfied.
And it managed to expose the weak points around my window and door frames while playing the audio from your 4" sub. Love your content because of your scientific approach, modern techniques and easy to follow narration. Thanks again!
Love te projects but, here in Brazil little subwoofer are impossible to find on the market and the rates make it crazy to bring them from there. What I'm getting at with this is: you could make a 3d printed or laser cut DIY neodimium subwoofer. I'm sure you have absurd knowledge about it that would make building simple.
Greetings, success!
Paul Ellis of Polymate3D has an open-source, entirely 3D printed driver design, including a passive-radiator enclosure to boot. It's obviously pretty inconsistent as mentioned above, as the cone is printed from TPU, not anything exact about the manufacturing yet, but it's still really impressive what you can do with only a 3D printer!
Only thing that isn't printed is the magnets and wiring. Thomas Sanladerer has a video about it. Always wondered if there was a way to apply some of the concepts HexiBase explores in terms of enclosure design, to that driver design. Pull the most power and accuracy possible out of a 3D printed driver.
Absolutely worth the wait 👍🏼
Towards the end of the tests I had completely forgotten it was a 4 inch driver. Very impressive stuff. I always enjoy subwoofer challenges like this. Anyone can slap 4 12's in a
massive box with a port big enough birth an elephant and rattle the neighbors medicine cabinet (not to say I don't enjoy crazy builds), but not everyone can pull this kind of response out a singular 4". There's just so much more for me to learn!
ive been wanting to make a tapped/folded horn for a while now. maybe one day ill finally get around to it... this was awesome looking!
He designed one for the demo/display unit Audio Dynamics builds & has available to their dealers, incorporating their 250w base model 8" sub. It was modeled in a huge number of different size & shaped showrooms & locations within. For it to perform so well, on such low power in so many applications is very impressive. If there is a dealer near you, take some time to visit & sample for yourself.
