So unrelated to this awsome video. You had my wife running around the whole house checking our smoke detectors thinking the beep in the video was a dieing battery.... 😆 🤣
U shot out man lol ur lucky to have a wife like that with u every step of the way God bless u both I hope my box looks that good when u finish it 😉 can’t wait to hear it ….
4th orders and 6th orders don’t have more output than ported boxes , they just provide that output in a different bandwidth. In my opinion 6th orders have the best bandwidth but it’s not worth the size unless you run small subs, the rear chamber couples with the front chamber and extends tuning on rear and front so that’s why they play a lot lower and “windier”. I’ve found some good results from building a regular low tuned ported box and adding a small front chamber in front of it , usually boosts output up high and helps it load a little better but again just makes the box bigger
They do have more output tho if you compare 2 12s in a ported box and the same in a 4th order, they will get louder because the box is bigger which increases the efficiency
@@justinatmidi not always, remember you’re eliminating the back wave with a 4th order so you’re cutting the output almost in half, and saving some of it with the big front chamber. Ive seen people lose a few decibels with a 4th order direct swap from a ported, but they definetly gained sound quality and bandwidth
@@modernbassheads5051 it's probably not correctly designed, or maybe a 1:1 ratio which is less efficient than the 3:1.....there's a reason most spl builds are either 4th or 6th order, they want the loudest possible setup
Yeah...great explanation...also I like that you call box types as "laymen" ("4th order" and "ported"), because they can understand things more easily what you're talking about...I just want to make clean few things for those who dont know about this: "4th order" is an enclosure which have 4 acoustic orders - as the name says, but there are more types of 4th order enclosures, because given number of an acoustic order is not limited to a single loading arrangement - especially when the number is 4 or more. So, actually the box you called "4th order" it is a 4th order "bandpass" box, and the "ported" or "vented" box is a 4th order enclosure too: 4th order "bassreflex". How to count orders in this case: start with a sealed (closed) box - which is a 2nd order box, then add an another chamber to it - +1 order, then add a port to this added chamber - another +1 order = 4th order bandpass. For ported: add to 2nd order sealed box a port - +1 order, but now, the driver's cone is outside the box, so the sound what makes the driver's cone interacts with the sound what makes the port, which is an another +1 order = 4th order bassreflex. And yeah, because of different types of loading arrangements they are working as you explained them in the vid. Also Hexibase have a vid how to count acoustic orders, it is on Audio Dynamics yt channel, and he shows several variations of loading arrangements too, which are basically the most known subwoofer boxes that even all laymen should know about.
The 4th order also protects the sub. The sealed portion helps the cone from moving too much if you will….. so you can abuse the subs with little effect.
Appreciate you bro I’ve been in the profession for over 30 years and I was a slave to box programs and recommend specs but you really inspire me to be more personal with my builds thank you may God continue to bless you and keep you in Jesus name
Would give these boxes the title "special use case". Argument could be made for use in an application where minimal power draw is a necessary component of the system; the efficiency of a 4th order nets a ~3 dB gain when properly tuned. This efficiency compensates for lack of power (watts RMS). The downside of all this is the stringent requirement for proper tuning - with the listener understanding this type of enclosure may be built to suit musical preferences in some cases; and it takes considerable extra work to construct a box that looks like a blank slate, in addition to all of the properties listed in the video (larger size, long port). Also, if amplifier gain is improperly adjusted this box has a propensity to cook woofers; these boxes have a tendency to mask signs of driver damage - as once learned by a young man and a track called "woofer wrecker". Very good content, thanks!
My brother... BossDawg.... Sir... I 🫡 salute you sir for hands down the best informational, simplified explaining of such a complex topic I've ever experienced... Thank you, because so many people try to sound as smart as possible so much that they still ain't said anything at all or answered any questions so again.. thank you for being a master of your craft
I know this video is a couple years old but just wanted to say brilliant explanation by using your hands for demonstrating how 4th order works. Simple and effective teaching method.
Thank you brother for clarifing the difference between a regular ported box and a 4th order box. I wanted a 4th order for my toyota, but after listening to you, I will stick with a regular ported box.
My go to for smaller efficient systems (single sub wanna pound have huge range and you have the room to make a correct parallel 6th's needed volume) enclosures is the parallel 6th order. Can't get better range and like you preach it's allllll about the enclosure. I have 2 parallel 6th single sub 12's 1 in a GMC Envoy and it not only utterly pounds it has massive range for a huge array of music which is totally me.
Good video..folks don't understand the importance of the correct enclosure....they just wanna fit in and have what billy and Tommy have .not knowing it won't work for them..
The smoke detector needs a battery. Got walking around my house trying to figure out which one of my needs batteries. Good info. I have a question is which box ported or horn, sealed for a truck bed like for a old school. blazer , bronco.
So after watching your videos and countless others, about speaker design. I have to say I am probably wrong, but it seems that the best enclosure to get loud, deep, and accurate bass. Would be a horn loaded isobaric, or a 4th or 6th order isobaric. The isobaric configuration to keep the size within reason, for car audio. Plus the enclosure design which offers the output over a certain bandwidth. I don't know but I've watched many videos on TH-cam. Which has me wondering "is this a question within reason?"
Good explanation 👏 👍. I build Bandpass enclosures and they can be very unforgiving. I built one for dj purposes. I decided to keep in my basement and it is a monster. Deep club like bass but it is very heavy. Dual 15 with a 18x8x7 inch port @ 8cu ft.
It's fun but overwhelming learning about car audio. I just wanted some bass and now I'm doing physics and fancy math. Now I'm determined to make my one JL audio 12 sound good. My first box was a fail. I try to sealed enclosure but it was about a half a cubic foot too small and I got to get more wood to try again but I think I need a bigger box for my trunk so I'm thinking about a fourth order or something that has the bandpass mode engaged 🤔. I'm just curious to how all of the different enclosures actually sound but I'm also on a budget and probably need to get a better head unit first
I have 2 HE2 12's in a ported box in the rear of my van, facing the back doors, under the bed, the bed is 6" away from the doors, giving space for the bass to come up, so this is like a 4th order if I understand you, since that gap is operating as the port. I used to have my speakers facing forward until I found the bass increased when I turned them to bounce off the rear doors, the van is huge, its a 15 passenger extended Ford. My other van has a Skar 10" in one of their ported boxes, I had it facing the rear, but seemed to have muffled it, its under the bed, the mattress is against the rear doors, so the space under the bed seems to be too much, there is a lot of stuff stored under there, so air can't pass through very well, I had to move it, its facing forward, I think it could use a better designed box. I try not to compare both vans as its not fair due to the sub volume.
YOOOOO preciate that again big bro. lol guess i made an impression wit that subject. thats koo you brung it to all who are uneducated in 4th orders like me. when i saw the heading and started listen to you im like yea this class is for me. i started this, lol. preciate the information big bruh and helpin me understand car audio a lil bit more. now do you think a horned box fuh those ELE's will do in my lincoln? get at me when you get a chance.
THIS ! this is the reason I subscribed to your channel ! To gain knowledge! You've gotten away from this here in the past while man , keep it educational and leave the drama b.s and everything else to Facebook Regardless ima still keep u A1 on my Playlist... still by far my fave channel !
After rockford rtti back in 1990 there's some freaky boxes I built back then making 6's hit like 10's, and 8's like 12's! Skies the limit if you tune it right!!
Great knowledge as always MBE if the sub or subs are caged in the inclosure I think it will be hard to dissipate heat if so then that's the con of a 4th order less play time own know am I wrong I'm a 40 year old bass head peace & bass
I wish all teachers would teach like this because I would know everything. I have read so much and watch so many videos trying to understand and it just did not make any sense until now.
MBE, ya need a webpage bud..I know ya business would blow up for sure! You got a ported prefab for 2 audiopipe TXX-BD2-10 going into a 04 grand cherokee? I bought a Qbomb for 10's the one with 4 triangle ports supposed to be 1.2 cubes per side and it aint it sure as hell aint after i got the subs in it. Pretty sure the box way to small and the chuffing is bad enough i had to back off the gain. I need a real box! I thought right off the jump i should just bought a box for 12s and stacked a 10 baffle on the front. why all these prefabs come out so damn small.
I never understood 4ths until this video thanks man. My question was gonna be would a 4th work as a center console build in a f150 but the whole ported area explanation answered that so now my question is would building a blow through even be worth it as I'm only running 2 sa 10s? (06 extended cab f150)
I can see with out a doubt your a beast when it comes to enclosures. Around 8.05 to 8.30min you talk about the air that actually being moved and where it comes from but you mention quickly and briefly that the port needs to be curved? Can you elaborate and touch more on that and what you meant
Bro I have 2 kicker 15 competition woofers on a 4000 watt American bass amp in a 87 Lincoln town car at 1ohm but my woofers are 2 ohm capable and I learned from you that 2 ohm is better than 1 ohm because at 2 ohm your amp can control the woofers on demand my box is ported I appreciate your knowledge because it helped me to understand so I want to know how to run them in parallel at 2 ohm
I'd take a ported box over a 4th order any day. 4th orders can be louder but definitely less accurate than a port or sealed box. If you really know the music or song, you'll notice that the lower bass hits are a beat behind what they should be.
How do feel about firing a 4th order up through the rear deck firing a rectangular port against the glass in a sedan ? Obviously seal everything off adequately….
I'm confused. So the reason it would not work is because the armrest hole wouldn't be big enough for the application? Are you familiar with the Deathbox designed by Steve Deckert? It bangs, I just have no idea how or why It's a strange box for several reason but I haven't heard any negative feedback from folks using it. Its apparently a one-size-fits-all enclosure that doubles power handling and generally solves all the problems associated with bandpass enclosures and uses a duct instead of a port. The only driver I have used with it is a Helix Blue10 rated for 200 RMS and had no problem pushing 350W. I am a beginner and I know that all sounds ridiculous but I'd be glad send you one if you could make a video commenting on it.
So. Need bigger hole than ski hole, because need bigger port for 4th order to be effective. So, if have a truck with a blow thru, 4th order more effective than a sedan with ski hole. But what if running 4th order with seat down or just out completely? With big port ofc.
You do know the enclosures that you build are technically a fourth order bass reflects? You probably already know that though but yeah that's what a standard ported enclosure is it's pretty cool most people that ask for a fourth order though are talking about a band pass fourth order
I always knew that there were subs who didn’t have a good application for a bandpass because of the size of the port. I always thought that meant the length of the port, but in actually it could be the length and the physical opening size that make it not worth it. Aka the box would be too big and not possible to do
what do you think about Labyrinth Vent Sub Box? I want one for a 12 inch Meso 1500 watt rms. I just don't know anything about them. Can you shed some light on this. Thank you.
Hey I have a challenger with the cheap audio system I only want upgrade I’m gonna change the speakers but what sub do I put under seat kicker type or small 8 skar sub. Again I only want modest sound for me no truck rattling etc. Also I want it light as possible ro keep weight of car down bc sports car
Looking at a 4th order it seems un fathomable it's loud, just looking it would say na just sound muddy n quiet...well my first experience almost 20 years ago gave me that opinion, from cheap small bandpass loaded enclosures a 10" visonik band pass many .5cf per chamber. Sounded like mud and no thump. It was just a cheap combo that was flashy and had cool window but was just junk, I didn't know better it was in late 90s?, but it gave me such a bad opinion of bandpass for years until TH-cam enlightened me. I've never built one but a proper built common configuration 6th order seems like it would be ideal, no sealed section and 2 tuning frequency's how can you go wrong other than botching the box...?
I thought people use 4th order boxes to reduced rattling and other things in that nature for cars with trunks. i see alot of the ppl out here in the east coast using these type of boxes...
So unrelated to this awsome video. You had my wife running around the whole house checking our smoke detectors thinking the beep in the video was a dieing battery.... 😆 🤣
That is the best and most simple description I have ever heard for a band pass box. Well done! Great video!
Agreed
And the worst, more misinformed thing I've ever heard.
I greatly appreciate these education videos. I'd love to learn the math behind designing all types of enclosures.
Thank you for all your videos and the information you share!
Side note. As a carpenter, my OCD kills me when your smoke detector chirps 😂😂.

Wow I never really understood the concept until NOW. THANK Major BASS
The 4th order also protects the sub. The sealed portion helps the cone from moving too much if you will….. so you can abuse the subs with little effect.
I've build a 4th order enclosure. It plays low and extremely loud for a 275wRms Subwoofer(JBL GT512D4). Im able to achieve 120db @ 45-75hz.
Right...i blew so many subs wit the ported boxes
Appreciate you bro I’ve been in the profession for over 30 years and I was a slave to box programs and recommend specs but you really inspire me to be more personal with my builds thank you may God continue to bless you and keep you in Jesus name

Looking at a 4th order it seems un fathomable it's loud, just looking it would say na just sound muddy n quiet...well my first experience almost 20 years ago gave me that opinion, from cheap small bandpass loaded enclosures a 10" visonik band pass many .5cf per chamber. Sounded like mud and no thump. It was just a cheap combo that was flashy and had cool window but was just junk, I didn't know better it was in late 90s?, but it gave me such a bad opinion of bandpass for years until TH-cam enlightened me. I've never built one but a proper built common configuration 6th order seems like it would be ideal, no sealed section and 2 tuning frequency's how can you go wrong other than botching the box...?
the phase relationship will be all over the place. if you just want spl numbers sure. if you want some decent sounding music it maybe a problem.
I have a 4th order one sundown x 12 in a 16 charger tuned to 35hz I love it but what do u recommend for one sundown x12 v2 d2
Whatever you want to run. Fuck what I recommend
A single 8 in a transmission line 😍
FACTS!!!! I hate when I have to explain to a customer when they really don't know
fantastic😮
So most of the time go ported cuz its more applicable to most applications cuz i have a limited trunk space so for me a 4th is not an option
I thought people use 4th order boxes to reduced rattling and other things in that nature for cars with trunks. i see alot of the ppl out here in the east coast using these type of boxes...
Preach

How can we learn to figure out the right relation with port area to cone area/box volume/ sub specs?
What type of wood did u use for the box in this video?
Can’t focus on what you are saying with the low battery beep of the smoke alarm in the background. 🤷🏻♂️
