Thanks for testing my submission ! I did not do any calculations on it, as i dont know how :p My music preference is low and slow bass, so it works out :) But test the other "similar" enclosure for sure.
Nice design without doing any calculations... good job! No disrespect ! these(snail) box designs r difficult to build in the real world not interested in another design similar in design. Thanks u 4 submitting neat to see...
I'd like to see this same box with a consistent port width tuned around 30hz. I think how that port gets smaller at the opening is probably messing with the potential of it.
I think what Pete said about the frequencies is correct because low frequencies tend to move more air and chuff more through the ports than the high frequencies do so the overall performance in the end is not to scale.
Remember that hexibase was replying to a question as to whether or not a subwoofer enclosure can scale up in size. The answer is no, unless you also scale the size of the sound frequencies. If you scale both of them, then it works just fine.
Dude, you have GOT to update your Playlist page on here. I can only find the first 4 episodes of S1 for the boom or bust videos. The rest are only showing in the "videos" category/filter, and it's just individual uploads that are peppered in with everything else. Thanks for the content, well done.
Lol. I made that design 2 years ago for a 3” grs speaker. Was not impressed though since it sounded just as loud as the square conventional box. At least my version did.
@barevids Thanks for replying... doing what we love (dreams/visions) are not for everyone. Wish you the best... Never give up... 1 day everyone that doubted u will tell everyone when they met you. Good luck in the future. Joyfully looking forward to seeing where you go from here? 👍
NExt episode you should revisit all the other boxes, finding out if they improve their scores with moving them around like you did this one. Cheers brotha. PS - Check out the numbers of the fibi box, and if they are good (which I have a huge hunch they will be) let us see em!
i submitted a ported W-bin sub i think the peeps would like!!! needs few supports for bracing but not hard to remove and probs less print time than most still!
Ohmygosh, thank you!! I wanted to submit that a lot but I have no CAD Skills!!! :D I would also love to see it with the ports blocked, so please try that Sam if you are reading this!! :D You might be able to use foam to block the ports! The reason I want to see this so badly is that I have a pair of sealed W-bin's, and for outdoor music they perform amazingly down to around 40hz :D
@@tigerelectronics5966 oooo good idea id love to see the difference too, Niceeeee, i dont own any but the original design (Klipsch la scala) and experiencing them at outdoor events has me curious in the same way! and maybe given large mouth area horns have done well in the past, maybe the W-bin will be the winner in an enclosed space!
@@keatonjones6115 hehe the efficiency is also brutal, I just run my two from a 75 watt per channel amp and it's plenty, and I've just got some cheapo 15" drivers in them! :) if I use the amplifiers full potential, it hurts my internal organs to stand Infront of them C: Yes, I definitely think they'll Win! But they will suffer on the really deep low end, since they can't really reproduce anything below 40hz with any decent efficiency. But I still think the average will be so extremely high that they'll win! :D You're a lifesaver, now I finally get to see impedance curves and everything of a W-bin! I've always wondered how they look like, my amplifier runs extremely hot when driving them, so I suspect the impedance is very low all the time which is honestly perfect:) Gosh I hope Sam takes the submission, I really want to see this!
I should have a enclosure for you in a week or two. Going to tackle the test print this week end. I think you will like it😉. I see you are using cura as your slicer what printer are you using?
This enclosure is sick! Personally I love the lows. In that 20-30 range. Noone makes boxes tuned low enough though. Im trying to get a box for 2 12s tuned to like 28 Hz but they are always tuned 32 or even 35. Anyone know of any quality boxes out there tuned to even 30? Even Gately only tunes down to 32.
Remember that Pete is responding to the question as to whether or not a subwoofer enclosure can be scaled up. He answered correctly in saying no. A more correct answer would be no, unless the frequencies were also scaled which is exactly what Sam is doing. He's scaling both the enclosures and the frequencies together.
Since we are scaling the frequencies as well, and the results are falling in line with common knowledge of their full-size counterparts, I am going to assume Pete did not actually watch a full introduction to this test before making his assessment. It's a fun series and I enjoy your analysis of the impedance curve and harmonics. It's all stuff DIYers/Hobbyists spend a lot of time "modeling" but very little time actually building and testing in a controlled environment.
Just.wonder 🤔? Could the amp/source be playing a bigger factor than we think? 🤔 the tests have been the same however...distortion or gain or who knows from the amp or source? Just a thought....
have you thought about using an electric motor with a rotational converter (like an engine piston) that way you can put huge power into the motor and for cheaaaaap! unlike regular high power woofers
It would certainly improve efficiency since normal speakers are only about 1% efficient. The downside is how would you be able to quickly transition between different frequencies? Like if you had a bass tone that was alternating between 20 40 60 20... Most electric motors are not able to speed up and slow down very quickly.
@@JasonWW2000 it would use a 3 phase brushless motor optimally, it would be limited to some non complex bass lines though but I'm sure it would be worth it
@@KClO3 Also, how would you control the volume? Sometimes the cone needs to move very little and sometimes a lot. Motor speed would control the frequency, but you need an adjustable stroke for the volume. I remember a sub that used an electric motor. Look up the Phoenix Gold Cyclone. Its a rotary sub. There's also the Thigpen Rotary Woofer which is like a fan. Neither design could better the conventional subwoofer. As inefficient as current subs are, they are affordable, can deliver low distortion bass and play a wide frequency range.
How are you taking the average? Are you just doing the mean of the decibel number or are you converting to powers of 10 and taking the logarithm of the mean log(mean(10^dB/10))? (E.g. mean of 60 dB and 0 dB is 30 dB, but power based mean is around 57 dB.)
Interesting design, but tuned too low. Take a Dremel to it and cut back the outside wall from the mouth back until lowest Fb rises to about 150 Hz. Then test it again :-).
Because that's what this whole series and community is about, car audio. No one cares what a speaker is doing at 150hz but they want to know if a certain design will be worth building for 25hz in their car. The pilot episode explains all this.
@@barevids Gotcha, I missed the pilot description, will take a look at it. Enjoyed the series, especially getting into the impedance graph and box loading. Good stuff!!
you need a 25hz scaled chart aswell. the loudest box is cool. Aswell as averaging the scores for the leaderboard. But it would be awesome to see a specific 25hz leaderboard.

He probably said 16 and overlayed the audio. 😁
@@Bassotronics nice to see the bass OG watching these videos
@@antreaskonstantinou8585
I love this series!
😂😂😂
The enclosure is too large for the driver.
BTW I was the guy that asked Hexi to be on boom or bust. That episode of his q&a is still there for anybody to listen.
Definitely do the Fibonacci spiral. Would be great to demonstrate how guesswork compares to calculation
I'd like to see this same box with a consistent port width tuned around 30hz. I think how that port gets smaller at the opening is probably messing with the potential of it.
Great episode! Enjoyed it! Please do the second fibonacci enclosure also!

The scaling works perfectly buddy.
@@barevids
Ok cool. 👍🏻
That’s good.
Remember that hexibase was replying to a question as to whether or not a subwoofer enclosure can scale up in size. The answer is no, unless you also scale the size of the sound frequencies. If you scale both of them, then it works just fine.
If Hexibase makes one it's all over.
You should go up in size to a 3 inch with each design. I love these little episodes

That 7th order design Hexi did is crazy but did you see his IG? He just made a HUGE one like that 😲😲
Yes do the fibonacci.
Also, do over ALLL enclosures in the csbin, find their BEST frequencies and see how loud do they get at tgeir best.
GET THE CUT OUT RIGHT!!!!!!🤣🤣🤣love the series sam keep up the good work!!
Or he just put the speaker on backwards lol
@@atticchopshop8180 duh lol I was joking about his post on Facebook and the short he posted😂😂
@@Abowe3404 Lol yeah, I saw the short here on YT.
Waiting patiently for episode 16 lol. I miss these series
I would love to see Pete design an enclosure he doesn’t have to print it !! Do a Colab !!
Sam addressed this before, he goes it’s not worth his time / effort. Maybe if enough people say it to him he might just do it
Imperial box anyone? Or a simetrical loaded Design?
Best Series on TH-cam
Lol. I made that design 2 years ago for a 3” grs speaker. Was not impressed though since it sounded just as loud as the square conventional box. At least my version did.
Brilliant, kid.
Keep it up.
Very humble, Sam...hexibase needs to get to work!
Any update u can share with us whats happening? Not negative 100%, just invested in seeing this/you succeed? Its been silent for quite a while...
Interest in this series was way lower than expected and was costing more than it was making so I'm unsure right now
@barevids Thanks for replying... doing what we love (dreams/visions) are not for everyone. Wish you the best... Never give up... 1 day everyone that doubted u will tell everyone when they met you. Good luck in the future. Joyfully looking forward to seeing where you go from here? 👍
That was a interesting build good thing it was a scaled-down and 3d printed that would be an extensive build.
Make that port a little narrower or longer and that box would be a beast on the lows. Its a shame its not tuned appropriately.

Make your port longer by a bit >> th-cam.com/video/dU0qirh3Ut8/w-d-xo.html
if you allow us to do isobaric designs we could get even crazier with box designs with the general enclosure size reduction that isobaric allows
I have have watched every one and I agree with pete , I think there’s something going on with your scaling model, but I still love watching this 👍🏻

A more correct answer would be no, unless the frequencies were also scaled which is exactly what Sam is doing. He's scaling both the enclosures and the frequencies together.
I promise you buddy that this all scales perfectly. I made sure to do plenty of research before starting this.

Any update on this series pls?
Please do a pickup on this
Is this series dead? 😢
what about adding an enclosed section on the back of the speaker
Seems like a compound tappedhorn with higher tuned front and low tuned rear facing ports would take the podium
That enclosure should be called the Nautilus.
Put it on its side, use clay as a prop. Rotate port on enclosure in the y axis
Just.wonder 🤔? Could the amp/source be playing a bigger factor than we think? 🤔 the tests have been the same however...distortion or gain or who knows from the amp or source? Just a thought....
Genelec has similar design sub. Barrel like subwoofer and the port is spiraled
Is boom or bust.. over???
No
i made a 12"" sub enclosure like this out of MDF
Is this the last episode in season 1? Haven't noticed any uploads in this series lately.
Planning a wrap-up episode
Was this the last episode of season one for Boom or Bust?
Nah just been busy
@@barevids cool, I was getting worried
Hi.
Anything else coming?
No more boom or bust for now, not enough interest
this needs running on a crossover with another speaker design box for the other higher frequencies seperate
They build the box the the speaker listed if it doesn’t work well that a design issue.

Its clearly not tuned for the higher frequencies. It does damn good for the size of the woofer.
A 147 is a STRONG score at 25 scaled hz!!!!
What is that first bass track 😩🙏
song name on 7:10?
When be some new video?
What happened to episode 16
Not enough interest
Any interest in repairing a Bass 30K?

Just the average buddy
@@barevids I was just curious because 150 dB is 10 x the magnitude of 140, thus the average of 145 is actually less than the mean sound level.
@@TimpBizkit you raise a good point!
maybe a bit too late, but what song at 8 min?
Damn 16 hz is crazy😂
Interesting design, but tuned too low. Take a Dremel to it and cut back the outside wall from the mouth back until lowest Fb rises to about 150 Hz. Then test it again :-).

9:09- Said your mom
It doesn't scale tho 😢
Those numbers are not correct.
25 Hz not sounded like an 80-100 hz note. Not sure what scaling is.
Watch the pilot episode to understand this series
Horn not designed to load the cone... Floppy loose cone slapping around
It's tuned way to low!
Never!
I don't understand why u call it scaled. Why not just call it the frequency you are testing instead of relating it to sub usage.
