i saw that dual 6th order bypass and he said tuned for 40,50,60 hz. My Heart feel in love with the idea!
So did mine, but that idea could lead to Phasing and cancelation issues.
Yes, I wonder what the real world performance of such a tri-ported enclosure would be. The other bandpass designs can be peaky or smooth depending on the specific size of the chamber vs the port area. Frequency cancelation is typically a bigger problem on 4th orders, but i have no idea. Why not do 2 drivers with 4 port sizes? Would that still be a 6th order?
i don't know what he is saying my RTTI binder shows typical 6th order is only ported to 2 frequencies 1 octave apart / 30-60 or 40/80 35/70
This video is exactly what I was after; a basic rundown with diagrams of bandpass enclosures. Thanks man, appreciate it.
This is dope!!! I’m bout to build a bandpass box and needed this info to help me decide which order to build.
Great analogy on the series connection you seriously explained that better than any of the other 5 million videos I have watched thank you
Your very welcome 😊
My 6th order bandpass 12in subwoofer box that I had in an extended cab S10 was the best setup I ever had. It was a down fire setup with a ported 1.2 cubic foot box that had a tuned 3in diameter PVC port, box was filled with poly fiber fill pillow stuffing, with the face of the subwoofer pointing downward and also in a somewhat ported enclosure. I had one Alpine Type S subwoofer on 500 to 600watts, two 6 1/2, two 3 and 3/4, and two 1 and 1/2 inch tweeters that would out beat just about any other system that I had heard at the time in person. Loved it. Traded the truck with the box in it not thinking about it till after the fact.
Stay tuned. I'm working on some new content for you guys.
Finally someone could break it down to a science Great video
That 8th order damn that's some mathematical stuff going on there never seen one b4 👍 good stuff
Thank you for knockin that out in under 10 min. Appreciate it.
Just found your channel today. Best of luck man!!
Thank u bruh. I learned something today. Thank u for the knowledge!
Another great video, but was wondering if you could explain the winisd portion of the build, specifically the plot wave peaks and how to adjust the parameters of the box in winisd. Thanks so much again for the very informative videos
Stumbled onto this video. Thanks for sharing.
Subbed!!
Love your channel! I'm ballin on a budget and this really helps! How do you calculate internal box volume and how do you go about tuning your ports in these?
Very informative. Answered all my questions. Much appreciated
Thanks for the compliment, stay tuned. I'm working on some new content for you guys.
i took a decent after market 6x9 and i put it in a 4th order box . it was hooked up to my home theater stereo receiver which was hoooked to my laptop. it bumped for sure. made a nice difference ... i could hear really low bass
Great Video Man! I want to learn more about design this bandpass boxes. Thank you
Very good videos I love all your videos very informative thank for the information
Good shit man, love the visuals
Glad you enjoyed it.
Do the chambers right in front or back of the speaker itself have any influence in tuning or only the ports from the chamber to the exit of the box have? thanks
Video was badass thanks Boss!!!!!
So the dual driver 6th order can function as a 8th order?
Great video! Thanks!
What are your thoughts on a dual chamber 4th order but instead of the port being in the chamber that is shared the it would be a separate ported enclosure for the basket side of each sub but then the face of the subs share one sealed chamber? I having figured out the port tuning yet but chamber size would be 1-1 so all 3 will be the same volume
Very, very good analogy!
Excellent explanation. Thank you.
Great video!!! I am a bit noob at this so I am interested in 8th order bandpass. Is there any program how to calculate box or how to make one?
Great Video Man! Do You Plan On Making A Video Where You Design A Bandpass Enclosure From Scratch? That Would Be Awesome!
Great video. Thanks for sharing.
New to speaker design. Is the order referring to a different equation? Like 3rd order would be dx^3/d^3y ?
Super! Thanks for posting.
very informative!
Great video & tutorials.
Layman's terms 👍
Simplified 👍
Sir which design would you suggest for optimal performance?
Just subscribed you are very thorough on explaining 👍
Thanks for the compliment, stay tuned. I'm working on some new content for you guys.
Great explanations. 👌
Can you recommend 6th or 8th order websites or software to design box?
Can you close off the Middle Chamber and make it to where both speakers back waves don't interact?
What would that make it?
Fantastic Thank You.
The energy from the band pass that is ported in a series would for example... the rear energy given off of the subwoofer would go into the front energy of the subwoofer and since they are of polar waves wooden that cancel each other out.
This video earned my subscription 😁
Thanks for the compliment, stay tuned. I'm working on some new content for you guys.
Great video as always. I'd like to build a 4th order bandpass for a sundown x12. Where can I get a program to allow me to build such a box?
A favorite design I love, dual 6 order. 8” and 10” woofers excel in this configuration
I'm wanting to see what 2 18s would do.
@@bradykay9322 sort of unnecessary for large drivers that have a low Fs. Dual 3rd or 5th order horns that share a single mouth, that's what you want.
Fs = Free air resonance, the frequency it plays easiest due to the design/mass/suspension, and part of the reason big subs do lower lows is mass, more mass (and bigger air columns) resonate lower. And bigger surface areas displaces more air which has more impact (chest kick).
It's doubtful you'd get much chest kick off a pair of 8"s. Not saying you wouldn't get any, but it won't feel like it is suffocating you.
(edited typos)
@@iterminator309 my ported box does that now with one 18 in it. With both 18s In it you can't stay in it.
I enjoy your content have a few questions about how to place for p3s and a bandpass box . 1how would the setup look, 2 what would it like it like .3 how to tune it to play Lowe's.4 how thick would I be able to make the walls or baffles.5 the size of the drivers..... I have four p3s 12 in I also have two Sundown v3 10 ..... interested in a bandpass what are your suggestion
I love ur videos very informative thanks for taking the time to make them by any chance u related to Steve Harvey i swear you sound just like him (✌🏼💪🏼🔈💪🏼🔉💪🏼🔊)
On your classic 6th order bandpass box or any one of them for that matter how do you make it to where you can get the subwoofer in and out for service
You can actually leave the top detachable by using wood inserts in screws or what you could do is have a plexiglass window that's big enough for removing the driver and again use wood inserts and screws to remove the plexiglass
i have a 6th order isobaric sub from jbl called controll sb5
it sounds quite good to my ears
was wondering if it would work good or not even, I've never seen it or heard of one yet.
two 10" drivers in a duel chamber 6th order duel 15" PR in the center to handle lower fq and ported sides for mid / higher fq
Good video definitely informative enough to give people the idea of how to go about building a enclosure.
I'm working on some new content for you guys.
Do you have plans available for these designs? Thank you
What about isobaric 6th order to help with enclosure size only, and sound quality.
So what's the relation between the interchamber port and the exterior port on a series 6th? All I can find is that each port affects the tuning of the other port but nothing specific and certainly no formula's on the subject. The best I've gotten so far is that the front port lowers the interchamber port or vise-versa, nothing solid or demonstrable.
What is the best kind of bandpass box to get for a Rockford Fosgate 15-inch T1 inside my trunk to get the lowest bass possible
An Inverted transmission line...hope you have a huge trunk...lol
Which is sol bandpass can u send me blue prints for single and dual 12
Thanks, I didn't know there were different orders.
Best bass player
So could I put any kind of sub in a bandpass enclosure? I have a Hertz HX300 woofer but in the specsheat the only recommended enclosures are ported and sealed. But since a bandpass is basically both ported and sealed could I just put that sub into a bandpass enclosure? Or would that just sound crappy or possibly damage the sub?
48884BB it sounds like you 're referring to a 4th order. In that case, there is both sealed and ported sections. The sub you mentioned has the ability to move a decent amount of air. I'd say go for it. It would be right at hone in a 6th order.
cool, thanks :D
I've made a 6th order bandpass box 20 years ago and I did not calculate anything, so it sounded very bad ,I had to make it into a 4th order , that worked a bit better
They both work with beefy subs...so what are you talking about bro?
I think back in the days i didn't work with calculations ,I just built a 6th order yesterday and it works just after using the sub box calculator
@@225maine We fucked up a box with a friend. It had barely any sound with a 1200w sub. It was kinda surreal how stupidly little sound came out of it. Driver size doesn't mean shit
@@whatevernamegoeshere3644 of course only the driver alone doesn't matter, everything has to work and be balanced...but even with a perfectly built box,certain driver won't work with it no matter what.
@whatinthefuck shitniggadawg i gotcha.
I'm not a computer savy dude but I'm building a 6th order and I'm using a DC level 4 18" sub I'm making the box huge so I can tune it later could you please help me on what the chamber sizes should be please sir my box dimensions are 2'/2''/4' I listen to rap and slot of Rock love that kick drum
I have wondered if a sealed woofer (not a sub) with muddy midbass could be cleaned up by putting a partition in the box with a port so that at midbass frequencies it acted like a smaller box without compromising low bass (or maybe even improving low bass)? Any thoughts?
For the dual chambered 6th order how would you be able to measure for all three ports? Would you do two separate designs one for the large port and the other for the two smaller ports? Or is there an option in win isd to do create a triple chamber band pass enclosure
Thanks for the question, stay tuned. I'm working on some new content for you guys.
I was wondering the same thing
Imagine the enclosure cut in half lengthwise thru the baffle. What you have left helps you see what order you have. One sealed, one ported= 4th order. Two ported=6th order. From there it’s down to specific pathways of airflow and whether they work together or produce Outputs of their own.
QUESTION i have built tons of enclosures,but no bandpasses I've been wanting to but heres the deal,my computer is a mac mini out dated,its a mac O S X 10.7.5 so you might say well update it,i tried to el capitan and it went so slow i couldn't do anything,i googled and several people are saying the same thing,so i have zero patience and went back to original mac o s x,so i CAN NOT download box calculators,my QUESTION is how else can i get plans for a build.i want to try two SA 8 v3 d4's in a either single reflex or a dual 4th any tips dude ? thanks
A 4th will give you the flattest response and the broadest frequency range
Is there a difference between having the magnet/motor on the port side verses having the cone on the port side?
Good question!!
Do a isobaric box! Good vídeo
Is there any way we can get a video specifically on tuning series 6th and different types of 8th order bandpasses?
Stay tuned.
Yes please!🙏
The classic 6th order bandpass seems like a dual port enclosure. Is there an exposure that seems like a dual port but instead of two port they use two bass radiator?
This is actually a great question. The design that you just inquired has probably already been done by some company. yet not to my knowledge, but highly doable, and has me curious to try 😀
thankyou
hello, wanted to ask for your opinion as it will be my first build ever. Had a spare klipsch k27k woofer with BIC subwoofer amp plate rated at 240 watt rms lying around so thought of giving it a build. i could not find any parameters for this woofer. if you dont have any parameters how to design a ported box? thanks
In your case, simply focus on the running of the box. There are free tools to do this. Just Google "port length calculator" and that should get you going. Good luck🤟
@@BudgetBassHead will it work without any ts parameters of the woofer?
When I came along to learn audio, I felt the bandpass box was cheating spl and not true audiophiles box- due to steep drop offs with frequency- can you elaborate??
Regardless of the application, quality sound is, just that; quality sound. Excluding a particular type of enclosure, would be like excluding a certain family of instruments. Could you imaging a band playing with only horned instruments? but when you mix the drums, pipes, strings etc.. you get an optimal result. sort of like mixing sealed with ported enclosures. Or higher frequencies with lower frequency ports.
Very informative
@@BudgetBassHead Not really. Bandpass boxes is like this, trading a little bit of SQL for SPL. If you want tight bass and you also want it to go loud, then go for horn sub. You wouldn't be disappointed, I assure you.
.
When you go sealed or horn, there's no going back.
Thanks...
i just love sub with most dominan & super loud in 15-25 Hz . So what kind or what sub box that you prefer for ??
Any one of these would do.
i hate sub freq more than 40 hz box
@@AnunakiAtlantis in that case, you would definitely have to build a 6th order or better. 😆
@@BudgetBassHead thanks i will try it
What if ur using ur trunk for a box with ur sub firing inverted into a ported box that's ported directly into the rear deck plate into my car but the port is fired against my back window in my 98 Merc and it's only 1 12"K9 Rockville and it's supposed to be rated at 1000 rms I got a 1200.1 rolling on it with my gains properly so it's getting down betcha lol and it's clean as hell I was experimenting with it because anytime ur working with a trunk ur trying to push that bass note throw ur trunk throw a seat but my way not the problem in getting everything and mine is in the truck it freaks ppl out how I made everything work cause all I really used was pvc pipe and a prefab box from Walmart fr fr it's still got me scratching my head to be honest how it's working fr lol
In your 4th order box would it make a difference if you flipped the subwoofer around?
in most theories or explanations of how to build a 4th order it is the back wave that is traditionally, enclosed. though I have seen people flip their subs around for better thermal observation of the subwoofer. I typically keep the magnet enclosed. Good question, by the way.
I was wondering they same thing. Thinking the speaker part closed off is less bass. All I wanna know is which one is best to shut down the Block party when I ride thu 🤷🏾♂️
Great videos bro! based on ur experience which kind of box would be better to put on a side by side vehicle that out in the cargo area???
It really depends on how much real estate you're willing to sacrifice. If you want to use the entire cargo area, go with a sixth order. If you want to use only a portion of the cargo area you could do a smaller driver with a traditional ported or t-line. Or you could go with a larger driver with a sealed enclosure.
BudgetBassHead thanks a lot bro! Looking forward to seeing your builds
Thanks Sir,..for the great explanation, but which the best one to used ?
I think that it really depends on where you're going to use it, the amount of space that you have to fit it and if it's going to be inside a room, inside a car or outside your house.
@@JohnHMercer Thank you Sir, for detailed answer.
Hola , me gustaría saber qué medida puedo usar para fabricar un cajón 6to orden tengo dos Pionner ts-300D4 quisiera montarlo en un honda crv 2002 , tengo un espacio disponible de 14x13x41-1/2 de pulgada , crees que podría funcionar ??
Descargue el software WinISD Pro. Esta herramienta le dará las medidas correctas para su Hunda CVR.
What you didn't talk about in this video are the tuning frequencies. 6th order bandpass boxes can be tuned to fill certain octaves in the frequency spectrum. You can tune a 6th order to cover only half an octave or a full octave or however many you want. Bose uses the 6th order bandpass for their Acoustimass 5 series 2 bass module. In fact, Bose patented the 6th order bandpass design and are the only ones who make them and market them for home audio. Next time you should go more in depth.
Then there’s the 20khz cd and mp3 ceiling. But I’m ranting now
I was taught that the tuning frequencies of the two ports on a sixth order need to be at least an octave apart. Is that not true?
It's a good rule of thumb. One that I actually follow these days.
Which one of these is used in pro Audio?
All of them; but 6th orders more so.
Which one is the best/loudest?
Damn great vids bro I would like to see you grab a popular sub and make a 4 order using 2 of them!
I've heard that Bose has a patent on 6th order bandpass and they cannot be used by anyone for commercial products. Is that true?
Yes. Many companies have patent designs. Keep in mind, there are many ways to design a 6th order.
@@BudgetBassHead Thanks for the quick reply on that. I can't seem to find consistent information on just what they might still have patented. Do you know? The patent extract for 6th orders from them that I've seen is dated 1988, which would have now expired, but I see references in forums that say they still have patents and others that say their patents have expired. The last thing I want to do is wind up in a legal fight with Bose. And yes, I'm designing a salable product.
@@StonefieldMusic check with U.S. patent office. You need to give them
the patent number.
@@Dauntless.steadfast.fortitude Thanks. In the we used a 4th order design, which performs great for the application and doesn't come with the potential patent issues.

His channel is very informative &
very articulated 👍👍
Is a bandpass cabinet best for the Eminence Killomax?
That a pro sub isn't it? To be honest, any subwoofer could go in a bandpass. If it optimal sealed, build a 4th order. If its optimal ported, build a 6th order.
@@BudgetBassHead thanx
I have a bandpass box that has 3 chambers for 2 10" woofers. The woofers are facing each other. The middle chamber is sealed. The 2 outer chambers are vented. What order is it? Thanks much, great video.
It sounds like a 4th order. Sealed coupled with ported is classically a 4th. This one simply dual chambered. You could also do a reverse of this build and seal the left and right chambers and port the middle chamber.
@@BudgetBassHead thank-you. What makes me wonder is, do the woofers share that middle chamber? It doesn't look like a lot of air to share.
@@jackdaniels2905 if it's sealed, it doesn't have to be a lot. Typically 12 inches are 1 to 1.5 cu.ft. sealed.
Will bandpass hit harder then a vented box? Trying to sound like king Kong when I am coming up the block 🙈
With equal volume and capacity? no.
So an 8th order is basicly a 6th in a ported box?
In short, yes. It's an additional acoustic chamber.
Budget bassheads unite
💯
Okay but which order gives you the most SPL rating on average....
If you are looking for SPL, then a simple ported box will do you great. Remember, bandpass builds are more for broadening the frequency response, whereas, SPL typically focuses around one particular frequency.
Imagine a beat behind this video.
Makes a nice rap song about bandpass.
Can use this indoors with house amplifiers
Yes
Seen some guy try explain 6th and 4th order bandpass box in same enclosure wtaf this even possible
What box program is that
Which program?
My systems never had enough power .How did I not know dam some incredible speakers and boxes I would build back in the day wired to a crappy amp tisc tisc maybe time to go back and relive my youth a little and finally get it right .
@Jacob Person Sounds cool ,my biggest mistake back in the day was Rollin through my hood boomin everyone knew where the car with the boom was parked at night had 2. punch 12s and a 600watt redline amp running mono in series it boomed just not like it should have ,scumbags broke out my back window snatched my subs and amp had a new Sony CD player they couldn't get it out so they stuck a screwdriver in it and jacked up along with all my CDs ,so yah that kinda slowed me down threw me off the boom game game for a good minute .Now my house booms and my neighbors hate me lol.Good luck with system sounds like a real knocker ✌️
@@fishfire_2999 never blast your system in your neighborhood even

ghetto !!
But why????
Do you have a fridge next to your entertainment system?
You know there are some people that don't know what a 6th or 8th order bandpass is.
The 8th is the loudest desogn all czn be manipulated but too much gain and group delay starts to sound bad. Its a balancing act. And the filtering hides driver distress so be careful.
Yep. I just blew a sub doing this exact thing!
I'm into car audio for 25+ years.That being said, I would like more information on how to the proper air space for a given driver. is Consulting the manufacturer the only way. I ask because an associates ask me about build a box for two 15 Memphis Audio Mojo. The thing is they are custom I came to this fact due to wiring them in parallel they came to a dual one ohm load.He informed me that he got them from a friend and they only made six of these. any information on finding the airspace of a unspecified driver (Subwoofer) or a way of finding it would be helpful. I thank you in advance.
N.T.Z. Claw
if Port tuning is what you're looking for then there are plenty of Port tuning calculator on the internet that will give you an estimated volume for your internal space. However, without having the t s parameters it will be hard to properly build an enclosure for SQ or SPL purposes without a whole lot of trial-and-error.
BudgetBassHead thank you for taking the time to reply
I am sorry but I have to ask, you say that "you are into car audio for 25+ years and you don't know about TS parameters? That is literally the first thing you need to know when determining an enclosure, not by how it looks, I have also been building enclosures for 25+ years, alot of screw turning, cuts, blood, cutting with an oldschool handset, siliconing mistakes etc... if a customer would say, "I want a whatever order box" I would ask, "what kind of music do you listen to? What kind of mids am I working with? Sometimes the person would have kick ass mids and only needed a box that complimented the low end, not a monstrous sub lurking in their trunk.
Yes there are some subs that are awesome ..... if your only concern is spl, then that is easy, but if you actually want great sounding efficient sound vs "what it is going to look like in your trunk, or how cool it will be to tell your friends, "I designed this box vs that box" if you have the right ts parameters, you never know, it might just be that a simple sealed box handles the job quite well
@@gen-x_dude thank you for your input, I am not a professional installer I am a enthusiastic.
