I been building custom systems and SPL and DB drag stuff for 20 years. And I still enjoy watching your vids.
To be honest I feel the same it's always fun to watch someone having a passion for something and uses basic tools to do it
It’s always nice watching someone else point of view on it.
I want a spl box like this for a seat in an ex cab truck
Sir I hope you Keep bouncing?😎🙏🤝❤️ It never gets boring 😂🎉as a dad to 9years boy I say my kid loves it more than me 😁 we building now nice project together nise sloppy over 8k RMS system
I can't have enough of these projects ❤ it keeps me alive 💥
Blessings to you and your family sir 👋
This box looks ace by design
How to figure out same style box for 2 12inch avatar subs?📝 This type would looks slick with them subs they have beautiful huge motors ❤ I custom paint the basket. 💥
Love watching these box building videos. They are a prime example to show customers how much work actually goes into building a subwoofer box. In my shop people aways ask me "why so much"& "it's just a box why do you charge so much" and my favorite question "does the box even make it sound better" and all of these are great questions to ask a installer. As a installer I bought a eBay special $45 box for a single 12. And I built a box for a single 12. (Rockford fosgate p1) both boxes use that woofer. That way when people tell me it's just a box and it makes no difference on how the speaker(s) sound I show them a example of why you need a custom box built for your exact subwoofer.
Well said , and that's a Great idea ! Way easier to show someone , than trying to explain it . Plus they can hear the difference for themselves 💪😎👌
Hey EXO, When you lay down fiberglass matte... Try spray gluing the matte to the surface first :)
Man almost every thing Subwoofer related I need to know that I search EXO has a video on it. Noice
Look how far you've come!
I'm new to bandpass boxes but I have been researching 4th order enclosures today. Couple questions:
* Why did you do double wall speaker walls?
* Why did you use such a large port diameter? The larger the port diameter the longer the port has to be.
* What is the air space requirement for the front chambers of the speakers? Doesn't look like much.
Man just a young EXO I learned so much from you. I actually bought a soundstream trantula 12 because of one of your builds back then. Thanks for all the great content man.
I plan on a center port with a similar box. I have my pass through the trunk and the armrest is removable but is still functional.
After watching you load that one into the trunk I'm inspired to build it in the trunk. That was a job in itself.
So crazy to see videos from so long ago compared to what videos look like today 😂 I was born in 2004 got my first phone 2013 and still remember how difficult it was going from the first phone I’ve had to a newer one around 2019
Nice build... from a construction standpoint if you want to add rigidity to a box like that rather than drilling into endgrain you can cut a dado in the top and bottom pieces to receive the vertical pieces. You could use biscuits for alignment and a 1x1 firring strip down the side of each panel to screw into from both sides so you avoid endgrain.
Been watching this video over and over again during my 4th order build
Songs name?
2 screws and a board to make a circle thats a great idea cant believe i never thought of it thanks for the great tip
Nice video. I haven't built a sub box in about 13 years. I use to have 3 12's JL Audio W6's and I made a sealed box for them. Each sub had it's own chamber. The one important thing you want to do first is take measurements of the inside of your trunk. This of course is to make sure your box will fit in perfectly. The last thing you want is a box that's too big for your trunk. Take in consideration the trunk lid/door hinges and trunk hatch cylinders. They can get in the way when closing the trunk.
Was thinking about making my own bandpass box again. Been years lol. Like 26 plus years ago. Be for a 2003 Saturn Ion this time. Nothing special, either a 10 or I have 2 different pairs of 12's. Was thinking 10 then work my way up 🤣. Excellent video once again.
bruh, you have too much fun. Awesome video editing skills and music selection as well. Keep going hard.
Hey Exo, getting ready to do a 4th order build in a month or 2. I have 2 questions.
1. Is it better to have the speakers in the same space in the sealed section or have a wall in the center separating the 2. A wall would add support from flexing, and maybe sound/work better?
2. Square or circle port? My first enclosures where square and they where more vibrate, if that makes any sense. where my circle port was more blaaarrrhh! Which from what ive read as long as there tuned the same shouldnt make a difference, the difference between the square and circle ported enclosures i made is the circle was not sectioned, each speaker could see each other, all sharing the same air. Whereas the square ported boxes where like your standard ported boxes each having there own ported compartment. So this kinda plays into the first question, would a wall in the center, separating my 4 12s, add to the vibrating? Ive done a ton of searching and i cant find answers. Thankyou!
I know this is an old video but Baltic Birch is what people want for boxes. It's considered void free for less chance of rattles and buzzing. The stuff you bought is Baltic outer layer with a Fir core. Not a whole lot better than regular plywood. Baltic Birch is currently about $70-80 a sheet.
Thanks for not dragging it out for a month like ***** did with his box lol 😂
lol... ya know....
yeah but you see the difference in a slap and pound job (yes I know you're not finished exo... im totally not raggin) vs soundman taking his time? please shush with that bullshit dude.
***** I was only joking with my comment. :)
How big would you make a square port for this build
@@scotthilliard8406 depends on subs, size of box, amount of wattage, etc.
I suggest building an isobaric 8th order triple reflex bandpass enclosure for an advanced program.
My subs, one so far, it's foam has dry rot, I thought my plywood cabinet was rattling at first, the HE2's are about 10 years old, wish I had inspected them closer before putting them under the bed in my van, I am gonna have a hell of a time getting them out, have to redesign my bed to make it possible to get access to them later. I would love to get another box built, I like that setup.
TROLL TREMENDOSITY
Take the Red Pill
WTF
4th orders are becoming more and more popular!!!
Good going exo
box came out looking good mang! your lucky you have a lady that likes bass, every girl I know hates bass lol take care my man!
martymor69 girls only hate the loud audible bass if you get your thing turned down to where she can feel the bass and rattle that coochie she will have a whole change of tune literally LOL
@@jerichojoe307 damn strait
@@jerichojoe307 what's the resonate frequency of a vagina? Asking for a friend...
My girl is pretty cool, she never had a system and I put a couple 12” ‘s in her car a couple months ago, (just some Kenwood KFC-W3012) and she absolutely loves bumping down the road
@@jerichojoe307 like yung joc says "beats in my trunk, bought it just for the freaks"
Yo EXO got a question. Whats the air space volime for the Meso 12s? Their websight says 1.5 cubic feet after displacement but for some reason in a box built to these specs they sound muddy and not crisp. I'm upgrading from Skar EVL 12s and they sounded way better but also each EVL had 2 cubic feet air volume. I messaged CT Sounds mulitlpe times asking this same thing but they never reply back. Thanks for your time and help bro.
Okay, so the face plate...wouldn't you want to use like a weather stripping round the open to ensure an air tight seal? I know tightening down the bolts in their pattern probably seals it up nice but is it 100% air tight? Not ragging or trying to be a know-it-all just curious as I've never built a 4th order before.
I'm about to build a 4th for two massive GTX 104, hoping this goes well!!
GOING TO GOODWILL TO GET A SHIRT LMAO. dudes got enough money now to buy polo's to work in lol good dude.
I know this is an old video but i wanted you to know you inspired me to keep plugging away at making my 4th order fit with a 8 inch aero port in my 2019 nissan versa sv. The subwoofer is a fi sp4 18 v2.1 dual 2 and im going to be running it on a taramps smart 3k at 1 ohm with a 350 amp alternator and 40 ah lto lithium battery. The chambers are pretty close to 1 to 1 with the sealed chamber being 3.60 cubic feet net and 4.43 net ported to 40 hz. Im hoping for at least a 140 to 142 db at a burp.
7 years later this guy still has the same energy. #BassHead4Life
How can I change the port to a rectangle for a blow thru box on a truck? Looks awesome!
Nice setup, guess that's why you're going to Goodwill for a shirt.
Seems Bandpass is once again slowly making a comeback. It's a lot of work to do just for something you'll probably swap out next year if that long Exo.
Although I don't get the fascination of having a 200 lb+ loaded enclosure that takes up the entire rear space of a vehicle and lower gas mileage just to have more bass. I think the point of subs is to complete the music, not to over accentuate it.
Do you have a video on how you cut your speaker hold dimension for any size speaker?
So how would you calculate the sealed and ported sections...Would it be like having 2 boxes in one? Meaning calculate the ported section like you would normally and then make the sealed section half the cuft?
I need a recommendation,i have 2 JL audio 12wxv2.... im running 1 at the moment (@150w rms)and its not enough. Its sealed. Amp is Fosgate p300.1. It can do 300rms at 2 ohms. These subs are 4 ohm
I am wondering if a single 15" could sound as good or better on the 300 rms?
I kinda feel i should build the box for 2 12s i have before a purchase but dont 2ant to for a let down.
I had a bigger system with 12w6s...
I want loud deep SQ out of 1 15" or 12"...or 13"
Guys?
First get a 1ohm stable amp then find out if your subs are SVC or DVC than if they are 2ohm or 4 ohm if SVC 4 ohm run in parallel and bridge at the amp for a 2ohm load at the amp.
I have a 2003 Lexus LS430 that I need to build a custom enclosure for 12 inch subs I have 2 and built 12 inch 4,000 watts RMS 0.5 ohm can you please look into kind of my trunk and see what kind of box would go best thx I love your videos keep them coming
Just one question I have if you took the time and rounded off any square points made them more easy for air to move couldn't you get more sound with ease
Dayyyyyum. 2 12's be flexin the shit out if that car
That grit in your ashtray was jamming the fack out
Even the clutter wants out ;)
All that drilling and countersinking you've done in just this video alone, you should go to your local Lowes, Home Depot, etc and pick up a set of Dewalt high speed rapid load quick change countersink bits (Dewalt part # DW2535). I also use a Dewalt rapid load quick change chuck in my drill. I payed 25 bucks for that set, seems high for 3 drill bits but they have lasted me 3 years now with out dulling etc. Once you use them 25 is WELL worth the money. I bought them for installing kitchen cabinets but I've used them on box builds, my back porch, rebuilding my house, I mean just about anything that involves putting screws in it lol.
you create a monster!! now i see you are more detaliated than past..congrats..well done!!
that's a sweet box bro. I wanna build one when I get my car up and running. I got a good 7 months for that. I'm gonna stack some bread up and get quality audio. better to wait and get good stuff.
Can you make it from mdf wood?
Hey man I need some help! I have the ct audio meso 12" with a Memphis srx 1.750 amp! I was wondering what was the max amp I would push it to? And also what kind of box I would need for the single ct meso 12" as in dimensions? Please help!
Hi I have a tangband 3 inch and was wondering what type of box I should make for it, so it has good bass for such a little woofer but also having good sound quality? wanna make a cool little boom box thingo, cheers 👍.
Mate your video have always had the best sound PERIOD,the bass notes always came through sweet through the distortion
like these bandpass speakers sound really good
how come in the states it seems you guys all use plywood for boxes north of the boarder we all use mdf
How was you experience with using Birch vs MDF? Was it just as easy to work with, or did it end up picking apart a bit?
i love the box build but im building this for 2 10s not 2 12 so what measurements should I do or what should I cut off from the measurements
if I wanted to build one too, idk if anyone has asked. could I build a 4th order box with both of my 12s in the sealed portion at their combined cu ft, then continue the build as you would for the ported section? or do they have to be in separate sealed off sections. I only ask because I'm running my subs wired together in parallel at a 2 ohm load and want to keep it that way with the amp I'm using. thanks for the help if you have a second!!!
Dude you're a certified BASSFREAK!!!...I'm about to start vuilding my own sub enclosures
Good luck, Nathaniel!!! If you have any questions feel free to hit me up in the comments :)
@@EXOcontralto awesome vid EXO I'm making a fourth order BP for my ride right now and i know it's ages ago but I really need the name of the track that you had on in the car the first one. thanks X oh and what subs did you use um just curious about em but yeh i defo need the name of that firat song you played when you first got the box installed and went for the ride out. thanks man.
Any suggestions for a 4th order box with 2 12 inch rockford fosgate power T1's? Plan on installing in a single cab pick up
Sounds good, would have liked to know the work that went into the calculations for the box though
Glad I got to see this 4th order at the show. Keep the videos coming. It was nice meeting you Exo!
Best vid in ages Man,getting demos is good but we all want to see your shit like this more,great build vid,couple of cool tips and any bird that lets you film her inner thigh bass flexin must be super cool!!!
Any video suggestions for a good box 4 two 10,s that will sound good with both rock and rap ? Thank bud
You left alot of details out of making this box..
Like finishing the faceplate.?.
The measurements from the baffle to the side of box..m
What did you use to make the port?
How did you paint it?
And how did you cut the faceplate?
I'm trying to build a box for my 2, 10inch subs in my ford explorer...I just cannot figure out the dimensions I should use...can you help??
What kind of box would u think 2 MTX 9500,12 s would sound at its best with 2-2000watt amps
First, is the port on the side facing the back of the trunk? And also how far are the baffles from the sides?
Man your idea are amazing,but I want to know, is there a change on the sound,if you use other materials in build a box for speaker.. keep safe
EXO, I know this video is 5 years old. I was just curious what freq. You had that box tuned to? Looks like it jammed!!
Whhhat the heck, this is yur first 4th order. Dang. Ive seen u do some crazy stuff woulda thought u woulda tackled one of these along time ago lol. Im just finishing my first 4th order as well [only like my 5th build] but oyeah mad props on yur jigsaw skills. True backyard build! Lol. I had to get myself a plunge router and a circle jig - screw the crooked lines lol keep it up buddy
so annoying if i click a video on somebody's channel it opens in a play list
great video man looks like a good box
Sounds amazing man. I just got 2 W6 12's. Sure you're not a JL fan but these subs should sound pretty good in my Tacoma. I hope anyway
I have 2 10s in a 2.25cuft:4.5cuft box.
So
I've had the same table saw for about 12 years. It's slow af but it works lol
Very well built bro and that is why you inspired me in the beginning you are the reason why im a bass head thanks bro
EXO how do I know exactly what size port to build my blow through fourth order bandpass
How do these boxes sound in comparison to a regular sealed and ported? Are they mostly intended for spl setups?
Dam I wish I had your skills , I want a band pass box for my car too .
Hey exo i love all ur vids and now i am starting my own shop at home to work on peoples cars steros lighting all of it and its all thanks to ur vidos show me and give me the stranth to do it and yes i cant really spell to well my school sucked lol thanks bro
EXO did you put a flange on that port? I've always seen the cone flange pvc ports. Never thought about using concrete forms.
looking back at this video still a nice one any cut out plan for the box am willing to make one am still a fan i still couldn't beleave to tap out on the newest video with the kicker l7
The fact that you've made a sequel out of this surely means that you're gonna build a nasty 6th order? :D
How should you put your subs in the box should the back of the sub be with the ports or the front of the sub with the ports
Wonder what it sounds like with some bass. ( I mean like some jazzy upright bass )
Does it make a difference which way you mount the speakers
Awesome vid, much respect. If I were to build a 4th order. How do I calculate the the volume of the sealed portion the woofer plays in? In this case u have the woofer firing into the sealed area. If I were to mount the woofer facing each other. Hope I make sense?
Late reply but the sealed portion should be very close to manufacture specs. Example, if the manufacturer recommends a sealed box be 1 cubic foot, then you build a cubic foot sealed chamber for each of your subwoofers. Seems like lots of people go 2:1 ratio for musical, meaning 2 cubic feet ported for 1 cubic foot sealed. Generally, the higher the ported size, the lower the bass will be. Hope this helps.
Thanks for building this, I've been kicking around the idea of doing a 4th order box for my box body suburban.
i like the hundreds spent on audio but goes to goodwill for clothes lol EXO your awsome!!
Can i ask something sir wat would u recommend for me. Those size of box in a 12 inc sub woffer.? I cnat calculate the size for the 12 inc. is it makes sound perfect?
What's the best way to figure out the ported part of the bandpass with a big 8 sub setup?
hey EXO I have a question , would I be able to get the cut out sheet for every piece or would I have to pay for it , I love this design man , I'd really appreciate it , stay awesome man :)
Did u ever replicate this?
Should've used or built an Areoport 6-8"
You make it look easy
I bet this is a long shot but is it possible to get this boxes cut list and other info would be forever in your favor if not no biggie your still one of the best audio youtubers in the game keep it up exo
That was some nice leg flex LOL
Bro good build my guy how does the birch sound compared to mdf I heard mdf sounds better butb I want get more opinion on it kuz im thinking about trying birch bro bro
Beautiful build as always. how did you figure out the size of your port
Ive got some tuning questions for ya... I've got the same box design but for 4 10s and I just cannot get my port tuning right please help...
EXO makes it look easy!
Could you build me a box for my Dodge Challenger I want the base in the cabin not in the truck
It is easy

How to I win a 12" sub's for free
I did everything you told me to do
Exo Hi
I have two ground zero gzca 5k amplifiers at 1 ohm giving 5600 at 14 volts and at 2 ohms giving 2800 my subwoofers are gzhw15 spl dual 1 ohm but I actually tested them are dual 1.4 ohms so final resistance or 0.7 for every two subwoofers or 2.8 ohms these amplifiers are manufactured In Brazil is there a problem running them on 0.7 ohms and what should I do so that no damage happens to the amplifiers and if not who has a method to run the subs on 1 ohms thank you all
I know this video is super old, but Can you tell me the best dimensions on a 4th bandpass for 1 sundown zv.5?
COOL stuff exo! so glad i re subbed to you back a whole while ago!! EXO IS BETTER THAN EVER BEFORE!
great work EXO as usual the Impala build is outstanding its really getting it. good luck and keep up the fantastic work you always do.
looks and sounds awesome brother. i just designed a parallel 6th order for 2 re mt v1 18s going in a tahoe for a fellow team re member out here in texas.
Where did you hear that the subwoofer is at the end, if you can not see them? :D
Only times as a question? :D
hey exo, i'm getting a 4th order built, same specs (2ft sealed 4 ft ported double 3/4 speaker face) tuned to 46 hz, my car is a 02 sentra. would i expect to hit 18-20 hz up to like 60? thanks for your time :D
hey Exo bro would you have the blueprints for that exact box but for 2 15's? I'm wanting to build a bandpass for my two 15's
