Building a Tapped Horn with a NEJE Laser 

A tapped horn enclosure has to be my all time favorite designs for subwoofers. It just makes the most sense.

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

Yooooooo. I get butterflies every time I see that you posted man.

Cinematic camera shots like a Hollywood movie. Following your channel is super inspiring.

I could not push the 👍fast enough i really missed you content keep up the great work

Absolutely mind blowing amount of quality and patience!

Glad you’re still posting projects.

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.

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!

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 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.

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!

Nice project, practical way to make big sound from a small speaker

You have a great sense of humor.

Long time, no see! Glad to see a video from you. They are always good.

The in-car response was very satisfying.

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.

Awesome little laser! Thanks for the vid!

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!

the low end on that thing is amazing

Waiting isn't a problem - your videos always deliver!

Man, I wish you still lived in AZ! After all these years your projects never cease to amaze me!

So much good stuff in this video!

Again, I like your tracks... super weird and ambient. Dig it.

this was really job for an cnc mill, but appreciate the effort. Mind blowing results as always.

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!!

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.

Woah! Good thinking with the Harbor freight table!

I was just rewatching your 3D printed boxes and this came up! Good surprise

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.

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.

If this man put out a payed instructional course to learn how to do what he does I would pay for it.

From a car audio shop owner, it sounds great through my headphones!

Always grab my Sony MX-1000XM3 headphones to watch your videos so I can appreciate the details. Incredible as always, thank you for sharing!

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 🇰🇪

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!

Super cool as always

PS Sound check was YES!! Outstanding! Impressive multipurpose enclosure

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

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!

Hidden Gem. Thanks for sharing. Creativity and Knowledge shared, we are blessed 🙏

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!

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.

Nice to have you back. Enjoy your vids.

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

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.

does same or better than my under seat 10" sealed sub, design is everything

This is absolutely up my street. well done youtube algorithm! I'll be devouring the back catalogue soon!

Great video with lots going on thanks for sharing.

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 ;)

Sony WH-1000XM4 over Bluetooth on Galaxy Fold3. Absolutely incredible. The deepest base I can remember hearing over a RU-vid video. Not an audiophile tho, so I don't know the terminology of the finer details to point out.

Absolutely worth the wait 👍🏼

So amazed how a little subwoofer with the right box has such a huge output! I would absolutely love one of your boxes!😊

I have a suggestion for a potential future project. Something that I've been looking for, but have been unable to find anywhere on RU-vid 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!!

Awesome video! Great extension from a 4 inch driver.

You are seriously a huge inspiration. Your knowledge and capabilities in every field is just astonishing.

Water jet is what you want for plywood. No requirement for abrasive means the sapphire nozzles last basically forever.

Welcome Back Pete!!!!

Dont know if anyone has typed it lately but your the MAN !

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.

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!

Spring time is upon us. Time to make stuff! Your channel is fantastic; for ideas, and debunking old-school paradigms. Cheers from Texas! 🤘😎🤘

Have thoroughly enjoyed these video and your channel. Your expertise spans across so many different disciplines thanks for sharing with us.

lol, Dante and Randall, "you never go ass to mouth!"

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 ❤️

Cool horn design. I have two 38 hz "volvotreter" tapped horns in my main listening space.

Your reviews are very thorough and instructive!

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.

love these projects, though i want to see another 3d printeds fancy t-line

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.)

This, but with a 6.5" sub driver, in a horn enclosure and most guys in the car meet won't know what hit them, mostly because you could easily hide this completely.

Good to see ya PWK!

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

Watching this in my house, with Infinity Interlude IL-40 towers and a Dayton Sub. This thing sounds very solid. Well done.

I love Base. I am happy that i have stumbled over your Channel.

So glad to see another video. Absolutely great work.

incredible engineering and results!

crazy a 4" woofer can have such long arms to reach deep like that.

That's impressive.! A 4 inch in a horn enclosure can do that.? Imagine something as big as a 10.

So much fun stuff around your house :D

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...

LOVE the harbor freight benches for project spaces. Been using them for a few years!

new mic setup seems a little... hollow? the laser looks pretty good but 7 HOURS per layer... you are a patient man.

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.

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.

Excellent project!! Bass was deep through my JBL earbuds.

Always enjoy your unique and inspiring designs!

HE GOT THEM ELITES

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.

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!

Been following your work ever since the Realm of Excursion days. Glad to see your work getting more and more impressive. Keep up the amazing work

Welcome back!!!!!

A sub that makes tons of bass with out the annoying boom! I guess 4 inch's is enough depending on listening positions.

Man, if the sound coming out of my Klipsch with an 8" is any kind of an accurate representation of what your box is putting out, that shit is impressive!

Really well put together man so well thought out

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

Shoutout to @William Osman. Miss you bro. Thanks HexiBase! Another great vid.

Absolute 💯 Pete omg 😲 dude I love everything you did you really take things to a hole nother level!!!!! Fantastic job!!

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.

I suggest using the laser to maker a template for cutting the pieces with a router next time. Much quicker for sure. Great vid:)
