This is a fever project for me.. would much rather watch this than 99% of what's on Netflix

I absolutely love this series, I really hope it builds the channel 😊

Numbers don't lie when everything is the same, but the box. Keep up the good work, Sam. Everyone that is suggesting at improving this submitted box. Submit your design.. thats the whole point of this series.

I’ve been sharing the series on Facebook bass pages. I get so excited when new uploads come up! Keep ‘em coming

I don't know if the rules of your project allow but I suspect that that box would sound better if you oriented it so that the ports are firing into the corner and space the box back from the wall about the width of the port. I think this would have pretty much the same effect as the larger mouth. I built a similar box in 1990 using two 12" subs in a face to face isobaric. If my memory serves it was tuned to 25 and 65. I wired it at one ohm and ran it off of an HCCA 225 bridged. It literally knocked the suspended ceiling out of the demo room, but that also got the subs sold! We rewired it for 4 ohms and used a less expensive but more powerful amp and put it in the back of a Suburban. It absolutely slammed in that Suburban. We found that it sounded best with the ports facing towards the back door and spacing it about 3" from the back door.

You should print this box with flat sides to see if the diffusion pattern actually does anything

Best car audio content on KZfaq for last 2 months. I would add some strictly traditional box types. Your small sealed, big sealed, small ported, big ported, 2/1 4th order, basically any prefab box to compare to some of these one of a kind designs? I believe that the simple design is going to be better then complicated design.

What a great way to start the week with a Boom or Bust video!

I love this series, I'm in love with 6th orders as well! Love that somebody did this, awesome. I think clickbait is fine with me by the way, I was going to watch anyway! Edit: after watching, it's a pitty this box suffered that much from the harmonics and chuffing. Honestly, he needs better airflow, rounded ports would most likely help. Nevertheless, still fun to watch!

I want to see the 6th order series on lows seams to do good on demo vehicles

Dude, I have said it before but BRO this is the BEST KZfaq series ever!! Thank you, thank you, thank you!

May actually purchase the plans for the wicked one box. It’s holding its ground. I have 2 FU-300 10s that need a home.

Neat to see how it performed. 👍 complex also. Agree the woofer makes a huge difference... glad to see B.O.B. back!

This guy he could be perfect audio school teacher 🤜😁. attention to detail is mega 💎 and everything layd down for as so so simple way that 8 years old would understand ❤️ I love his work 💎 mega

My thoughts is when the air moves in a parallel port the pressure remains equal. But when it’s opened the pressure increase or decrease depending on travel. This then causes the air flow to either speed up (in) or slow down (out). With this giving a greater pressure out then the wave should be amplified further naturally.

He missed out to make chamfered edges but that really helps sound flow so for Spl it is very desirable

You should try a mini martin wsx sub, still one of the best hitting subs compared to other "industry stardard" pro audio subs on the market today.. plenty of accurate designs on the net, prob will be finding a driver with the right bl

This is an awesome show

Series is awesome you should definitely do a video recap with each box in order from loudest to quietest

I wonder if some of the distortion you see on the graph is from the material the box is made of. Would be a interesting experiment to lay some sound deadening material on the panels to see if it changes the wave form. IE cleans it up. This one had the better looking graphs out of them all

Low end monster 👿 enclosure 12:20

Now try an passive radiator enclosure 😁

I'm watching this using my JBL Flip 5 with the DSP turned off on it, so I can see the passives reacting with the video in my hotel room. I think the low side might need more port area and a slight decrease in enclosure volume. The high side looks good, but could use more port area for more output. From looking at the graph, that's what i get from it. (I could be wrong....Acoustic loading matters.) Could also be the tuning of the high chamber needs adjusting to widen the peak.

Nice! I wonder if doing a larger chamber for the low end hurt the score. Its good to see the testing. I am thinking the quarter wave tuning might be having the higher benefits for the cabin being used. I like the new setup. Thank you again for this series.

DOH! My boy... What did you do to my boy??!? Ha! Nice job. Really enjoying all of this.

Thank you Sir Barevids definitely the best content on YT by far Thanks for sharing your knowledge

Great video as always!👍

I'm curious on how it would perform when positioned as a c-pillar wall with ports firing forward

I'm curious about if a cone port vs a tube tuned the same. Witch one would be better.

I want to see a double horn loaded box.

Maybe this is why kerf style ported enclosures are so popular these days even though some argue that it does nothing & is just for looks.

Epic series!!!!!!

My slot ported enclosure I built fires to the side rear corner opposite the driver, and is significantly louder than rear firing the port.

Best Series on KZfaq

I did a whole lot of messing around on paper with 6th orders some years ago. I found a set of values that seemed to make everything fall into place. 0.5 - 1 - 2 - 4. Driver Qts = 0.5, port sizes 1:1, tuning frequencies 2:1, chamber volumes 4:1. Pretty sure that's how it went. Worked okay for me anyway. I called it the Badass Bandpass.

This looks like the Bose 302 pa base cabinet design.They called it the Tandem

I say a 6th order 1:1 ratio ported enclosure with both internal chambers tuned to the exact same frequency will end up being a good competitor to get the maximum SPL out of that little 2" Driver.

My favourite project so far ❤️😁 I would choose this over Netflix 😂💎🤜

I mean bro in SPL, similar to what we are doing it's all about moving the enclosure around to see were the score is the loudest so yes move it into an odd position thx.

Interesting. How much does driver selection effect the performance? I assume if the driver prefers a sealed side, like the mentioned 4th order, would there be a different result with one that is better suited to ported? I have no experience deal with this small of a scale and am just curious.

propper droppers .. havent seen that in a while!!

Cool !! I love 6th orders.

X3 the total port area and build a series tuned 6th next!!!

Sick video as always 🙌

Hmm.... the first dip in the impedance curve suggests that there might have been an air leak or something in the larger vented chamber, as it's higher than I'd expect it to be. Both dips should reach approximately the same impedance. And if there was an issue with the larger vented chamber, SPL at low frequencies would also be impacted. Looks like the box-modeling tool used to design that box also over-estimated the vent lengths required to achieve the target resonance frequencies. What are the sized of the chambers and the vents? Perhaps I can run it through Hornresp to see what it suggests the resonance frequencies should be.

Would it be possible to add a spl sweep into the testing just to see the actual peak spl on each enclosure?

I'm waiting to see if a p-flex gets printed to see how it stacks to the wicked one :)

8th order next!

Thanks bro good job

boxes with 1 port play louder than boxes with mulitple ports i think. like i imagine it'd be hard for an 8th order to play loud, tho it would play very even i assume

I'm all about horns. They rule

Currently building same enclosure design for 6 15" EMF LOWBALLERs Duel 2 OHMS 1 chamber 18 cu ft tuned to 30 hertz 300 square in port area 1 chamber 18 cu ft tuned to 55 hertz 300 square in port area Saving for Sundown Salt 8 or Teampie 7500 Goal musical with wide band width

This question of a 6th vs a ported enclosure makes me wonder if you are right I designed a ported enclosure with a huge port with a small enclosure.. so I can play lows. Should of tried it ports forward.

How did I go from watching videos of 6 18" subs pounding away to this?

IDK if anyone's tried it yet, but what about an expanding labyrinth design with the enclosure at 1.2-1.3 of optimal? Knowing that each solid surface a sound wave hits amplifies its output by 2-3db, why not take advantage of this phenomenon?

I'm with you on the wide port. I can't stand port noise. I've been thinking about a 4th order with the port blowing through my rear deck but whenever I model a 4th or 6th order, it's never great, and doesn't seem at all musical.

This is fantastic content, I would love to print these designs myself to test out, is there a way to get links to the designs? Looking forward to future content!

Sam what's the speaker that is used I wanna design a box and see how it does on your testing

Nice entry!

hey mate ive just sent in a W-Bin Sub with ported chamber and large mouth area

Great content.

I think you may need to do a pretest for best box position before you record the test. Still have a lot to learn about enclosure designs, but my goal is to use my 3D printer to build a hybrid ported/sealed box that is narrow for my Tundra Crewmax. Currently running Two 12" NVX 124V3 each on a their own APMI2000 watt Amp.

I have a box you might be interested in then. Its sort of horn, sort of ported. I can send it in after work

You need a real horn box .

I love your content! if I get time here ill probably try to make a series 6th order box for you to test out because I was planning to put my custom x12v2 in one. And I got one question for you aswell if you don't mind giving me a suggestion. So I was starting to plan my wiring and amp rack out in my car and I wanted to test everything out to just make sure it was working properly, my amps are the soundqubed u1 - 8000 and u4-500 and I hate the spark that happens when you wire an amp so I decided I was going to slowly charge up the amp with my variable dc supply however didn't realize the last project I was working on was at 24V and when I started applying current it jumped up to 24v and the U1-8k is in protect now. I have a good understanding of basic electronics basic electronics (finished school for electronic engineering at a community college) but we never played around with class D amps and the soundqubed amp doesn't have any labeled components other than stuff labeled like C5, C3 and stuff like that. I'm assuming its the preamp? but any advice on where to start with repairing this thing would be awesome!

Try Nicola's box!

Can i get the gcode to print this?

Yea, the average freq of the 2 is going to be the loudest, not just one side at it's peak.

18:49 hi Sam it is likely yours did better because it is a round port so less resistance on the air movement. Btw I have a design but don’t know how to use 3 printers or their software as of yet although it is something I am interested in pursuing.

❤❤❤

at initial glance it looks like they used nearly the same size chambers as I did on my initial test 6ths. I used round ports though

Hope we get acryl for demo

I've found that 8 ish hz higher then the tuning seems to be the loudest

Is there any chance of getting YT/spotify/soundcloud links to the demo tunes? Been trying to find The Bakery but all the slowed ones on here sound wrong and it'd be cool to have the official barevids test playlist :)

Woops.not quite a Bose 302 as that one has two drivers.sorry

Paraflex all day..

Is there such a thing as active ports? Ones that have a valve or plunger to control air volume of a port. Like a valve closes off the small chamber port at lower frequencies and vice versa with other chamber. In order to limit cancellation of frequencies. Or even combining ports together for lower frequencies.

Can I get some advice or tips on my amp? I have a CTsounds Atv.2 3000.1d and I’ve had to warranty it twice already. Everytime it’s gone into protect and “blown” it was the same issue. It doesn’t blow while I’m using it, what happens is the amp gets pretty hot to the touch. I’ll be playing music perfectly fine, turn down my radio then turn the car off and leave. When I get back into my car the amp is in protect mode

Do a collab with hexibase

Lol nasa t shirt, I assumed you must know?

Shoulda chamfered the edges. A series tuned 6th would be just as good if not better.

11:40 do you have a version of visions of the future in anything higher than 128kbps mp3?

Xocontralto van will be a sixth order

im building a 6th for my home theater sub. 38 cubic feet 21" 6ohm 2500W sub

Test it without the texturing on the inside also!!!

It's less "farty" than some of the others.

👀

Death box! Death box! Death box! ;)

MBE enclosures is a master a building horn enclosures u should reach out for one of his designs

i need to learn cad lol

NASA. haha

the 6th order series wins

My man, that is a TERRIBLE neckline on that beard. You literally have NO neck hair, and it looks wrong.

🙌🙌🙌🙌💎🤜😁 my guy 👍

This series is great on many levels. It’s scientific. Interactive. Competitive. And it’s bass. What more could you ask for from an audio channel? If you start interrupting the series with videos of you working on your kid’s cars, I’m gonna be pissed! Fido gimme a noise! (Totally kidding. It’s just an inside joke reference to Soundman, another KZfaqr)
