How to Build a T-Line Subwoofer Box
ฝัง
- เผยแพร่เมื่อ 26 ก.ย. 2017
- A T-Line or Transmission Line subwoofer enclosure is a box style that allows us to get low end extension out of our subwoofer along with a flat response. Different than a ported or sealed subwoofer enclosure this type of box design appears to be all port. How do we build a T Line box? Let’s make this subwoofer box step by step in this DIY video!

What is your favorite box design style? What else would you like to see me build in future videos?
What is ur best sugestion for a 2005 chevy truck single cab subwoofer box you think is better.
@omar - Not a T-Line. They get huge quickly. Take a look at someting like a sealed or ported enclosure. To determine if you have enough room for ported check out this video: th-cam.com/video/oKdAHZS1LP4/w-d-xo.html
Thanks brother i will ck all ur info, thanks for ur videos i am super pumped to customize my truck.
I like parallel 6th orders because you have full control over your pile of dog food. Ported boxes only let you move the left side of your dog food pile.
Triple chamber bandpass
Bought a router table 5 years ago. used it once. Since i'm subscribed to your channel, I learn more and more how to use it. Having the tools is one thing but knowing how to use them is a whole other story!
A routing table is a great tool for someone who is always fabricating things but how often are you out in the shop/garage fabricating?
My last project was a big elaborate 300g saltwater fishtank stand and canopy made out of Poplar with crown molding at the ceiling etc etc.. It came out beautiful but that was years ago.
Actively walking around the house looking for things to rout...lol. all good though, no upgrades needed.
I can't say enough about how much I like your channel. You're a master at this and the little details you add show. Thank you for the time and information you give to everyone.
Awesome video. I've been doing this, installing stereo's for 40 years, and it never gets old.
Woodworking is obviously your primary passion. It's great to have two hobbies that compliment each other. Two thumbs up!
So satisfying to watch
scghost that’s not what your profile picture shows
You are the best box builder i have ever seen. I am impressed with your attention to detail and craftsmanship. Well done!
What's up cuz !!!! You have a nice system yourself rolling in town!!!! Smooth Like Butter!!!!
Man you are a master at this. I could watch these all day. If I ever need a system and I got the money- I'm coming to you.
Nice work! Almost done with mine but used screws with smooth shank. Help cinch boards alot better than Spax full threaded.
Great project... I've built hundreds of custom car subs... loved it for many.many years... I used routers extensively, as well as routers to flare large PVC port tubes-from the inside at the speaker baffle board and both inside and outside the PVC port on the inside thereby eliminating the air from breakingoff/separating from the port just like in an airfoil.
This allowed the bass to smoothly and with much less noise extend the bottom end in a way that was awesome. Loved shaping what iz would pull vinyl or grill cloth over like sculpturing.
Boat seats are sculptured in a very similar manner and are dubbed 'sculptured foam'
BTW... I always found using the poly based professional liquid nails from a caulk gun and 1.75 inch narrow crown staples (still have that gun to this day) was the best way to fasten any MDF or particle board product. It work quickly and solidly and you never, ever have a joint to leak, break or even give in any way. the material will break somewhere other than the joint even if ran over by something like a dump truck. I always used a DuoFast gun.
Awesome build and video ! Thanks
This guy knows what he's doing. True craftsmanship!
You make the nicest sub boxes I've ever seen. Very professional! I love that T line sub box.
I like the part when you glue it with mayonnaise. Yummy! Tasty sound!
ah, i love the perfection in everything, brother! i'd also REALLY love to see a video on an Aperiodic Bi-Chamber box. we used to build them all the time at my last job!
Congratulations mannnn!!!Great job!!!God bless your hands!!!
I literally had just decided that I`m going to get rid of all the trunk space in my E36 sedan by building a T-line for an Alpine swr12d4 and then I saw this video come up as recommended, very helpful.

+Kristjan Tarkmeel Glad to have you here! Thanks!
THE "TAY-LAY DOG FOOD" BOX!!! 🙌🙌🙌🙌
The dog food explains all! th-cam.com/video/Q2VL_FHu9AY/w-d-xo.html
SoundmanCA It doesn't matter what you did Doug!!!!!
do you build custom boxes for people?
Another brilliant video Mark! Beautiful work
Wow extremely impressive!
Fried H sub woofer. Now they’re cool sounding, maybe a tad simple for someone of your talent though just two folded boxes!
Awsome build. I used to design these ban pass boxes. The length and cross sectional area are extremely dependent on the driver you're using. What driver is going into this box, also what frequency is it intended for? You may have gotten me back into this again.
Art and Design is so subjective that I'm not sure I would worry about those little design elements that took so much time and effort. That is for you, the beholder with the eyes.
However, the BOOM is objective and cannot be denied...
Great work!
Thanks!
Come wanting to learn about speakers. Leave learning a lot about woodworking. Awesome video! 🔊
Great video-tutorial, very professional looking speakers, looks like they’d sound awesome, if you know what I mean.
You are hands down the best on TH-cam, Well done Buddy!!!
I have a small request, could you show us normal folk how to design & build a horn type of enclosure for a car.
Keep up the excellent work!!!!
Love me a t-line. Mine plays down to 10hz and yes you can hear it. Ive lost track of the jaws that hit the deck when they hear 10hz and see that it is indeed 10hz clean and clear.
10hz. What a grest joke. What kind of ears do you have elefant?
@@thomasschafer7268 what the hell are you trying to type? Like damn I feel like I had a stoke reading that
I see where you have a customer build gallery on your sight. You should put a gallery of all the awesome boxes you have designed as well.
congratulations my brother!!!
I really like your videos, it's always very interesting. The only problem I have, I don't have a space to work in, otherwise I would build speaker all day! 😀
Incredible and beautiful
It would be perfect to add a tweeter to that. Just gotta diy a decent crossover.
Another vote for shallow sub, sealed box. I'd love to do this in a spare tire well
Sir please answers this. Really appreciate it. Please tell which sub and what box dimension will give deepest and loudest bass.
hey. i really like the way your vids are done. i have a punch hx2 10". and i think this exact box will be good. looking for low bass.
Looks very suitable for home audio too
you absolutely earned my subscription, great looking box.
+Matt Demko appreciate that! Glad to have you here
u r brilliant work
Awesome work!👍
Can you tell me what kind of tool at 5min and 9.32min is?
...I need that, too!
Question: Is MDF wood the only wood you use and or should it be the only type used, when building a Sub Box?
YOU ARE AWESOME!
You should use thick plexiglass for the last panel! Throw a few color changing l.e.d’s in it. If you make one, I’d like to buy it!!!
Man, I wish we had the nice LED's we have today back when I built hundreds of enclosures....I got out about the time Plexiglas was making a debut. All we had were some neon tubes which were always electrically noisy
Mantap, pasti alatnya bagus dan mahal
Could you clarify or comment on one aspect of T-line enclosures? As with any enclosure which uses a port, isn't the enclosure "tuned" to one specific frequency? This creates a bump in the frequency response curve around the port's designed frequency. So how do you keep it from sounding boomy at the tuned frequency? Is the roll-off from the tuned frequency in this enclosure smooth or sharp?
Got it ,thanks.
I have to admit, the first of your vids I watched I thought you kinda goofy. As I watched more my respect for you has grown. I am impressed by everything... not only your expertise and professionalism, but also your ability to communicate it through your videos. Good on ya man. Keep up the good work. 👍
You thought he was 🤓?
Even spacing is absolutely not obsessive. Everything.....in it's right place.
How do you keep the mdf from splitting even with predrilled he’s so close to the edge? I have never had luck with screws that close using a 7/64 bit
Really nice box
Absolutely amazing work! Very inspiring. Would you please do a shallow woofer sealed enclosure, How to get the best performance and lower range frequency outta these shallow woofers in the smallest possible box design. Preferably for a 10 inch woofer. Thank you and keep up the excellent work you do!
Wish o have thoes tools. But i ll try with the basics hahahahah Nice video
OK, that does it. I’m subscribing.
Nice work! What are all the kinds of box wood you use? Any exotic or weirdly cheap that work?
Can you make a video on how to create a fiberglass box with a unique structure as in a speaker popping out at with a slope? Like a unique box? Let me know what you think. Thank you!
Check out some of my older videos for fiberglass ideas. :)
Dayummmmm!!
9:28 Ingenious \o/
I have a 2013 Cadillac XTS which has a very deep trunk but maybe not too wide...This type of enclosure sounds perfect for me but could I get an enclosure to fit snuggly in my trunk?
Hi Mark. Please tell me what the adjustable jig is that you use at 3:24.
Wow. You do some incredible work. Very talented. Where are you located?
I have a 99 Chevy Silverado 1500 standard cab. what kind of box would you design for maximum bass out of 2, 6 by 9 speakers? I was looking at putting two of them back there behind the seat.
I’m thinking about a t-line box for 2 HDS201.8’s.. Would they work well in one ?
I purchased 2 15" skar vxf subs. The manufacturer says they are great for hitting low frequency sounds. I would like to build the perfect box for bass you can feel. What are your recommendations. I have heard that building the box with a slightly larger net volume will give you deeper bass?
So can you make a video explaining different sizes of subwoofer box and different
Si many tools, cool
Nice made
@caraudiofabrication who made your rectangle router template? you mentioned linking it in the notes but I do not see it listed.
You have some great skills ☺
+Dave Taylor thanks
He's a Genius. Awesome Work.
@caraudiofabrication Question - say I have a 6 inch driver of SN 139cm sq.... if I use 3 in one line do I use 139 as SN or 3x 139 as the SN?
Amazing work as always!!!Where do u buy the templates for the speakers?
Question? What would happen if you adjusted for a thinner line.
could u please make a list of router bits I need . my router is a combo crastman plunge and fix . I need a table to
Ooo! Where did you get those equal spacing dividers?!
Do you keep any of the wood patterns from your builds after you are done? Seems like they would take a lot of space, but also let you build copies of the same thing.
+silentbravo I have a cabinet dedicated to my master pieces.
in t-lines i've noticed the port is usually on the same plane as the driver. is that a design requirement? i would prefer to have the port rear or down-firing.
hi , if y have 2 woofers do I have to double the box or just ad the second sub displacement to the box volume ???
HI would it be possible to build a tline box using aeroports? can the same principles be applied?
That’s awesome. I wish I had a spare week and $10,000 worth of tools to be able to do that.
Hello mark, i just got a 18 inch sub for cheap, (50 dollars) can you make a video about making a 18 inch subwoofer box? :)
It would be the same video as making a subwoofer enclosure for a smaller sub, the only difference would be the enclosure size and cutout holes would be larger.
Hi there, you got some sweet skills there mate. I like how clean you keep your shop, its spotless, and I also like that COD you got everything just has to be perfect. I am like that to, with doing mods to cars. I was hoping we could have a chat on facebook or something. I saw this video were this guy had like 2 6inch subs in this big ass box and he was doing close to 150db with it. sins then, I have been thinking, about doing a single 8 inch doing 140 plus db. Do you have plans for one of your killer boxes for a 8 inch able to do 140 or better db.
Why can't us the regular humans find guys like you to build stuff and install systems for us? Instead it's dudes that be like. "Yeah bro we got pre fab boxes ready to go, nah we ain't got no table saw in our shop."

There are plenty of great shops out there, you just have to do the research and find one in your local area. Yes it can be a pain in the butt to spend hours calling to different shops and visiting them to see what they can offer, and their level of work. I figured if you are going to spend a thousand or so dollars on a Subwoffer enclosure, you might as well make sure it is done by someone who knows what they are doing. A shop that can produce top tier work is going to cost some serious money, you figure about $100 to $150 and hour plus materials. I don't know what your budget it like or what your end goal is, but I can promise you one thing, if you are trying to find the cheapest installer, then the work you get from it is going to reflect the money you invest in the shop. SO the adage still stands, you get what you pay for. :)
I built an enclosure 4 layers fiberglass to hold a vented 12" L7 up in the quarter window of my 99 Yukon. I tracked my materials and hours, it would cost a customer round $1500 for this enclosure.
For real dude
I want to use a high end 15 '' woofer. In a t line. Can you give specs and data's ?
I wanna use 6.5 inch car speakers in my,i will make a ported box for midbass, in which frequency should i set the port?
A folded horn design that would fit inside a car would be cool to see done if it can be done! :-)
Big box . Best have a good speaker
Amazing work!!!Where do u buy the round templates for speaakers
Can T lines be use for any single sub? And whats the best thing about T lines?
A "T" line is easiest to design build and install in to the vehicle with only one subwoofer. The overall size of a "T" line is pretty massive vs other box designs. The best thing about a "T" line box is the ability to flatten out the bass curve and allow a subwoofer to play more accurately with fewer spikes in the frequency range.
As comparison a "bandpass" designed enclosure will be "tuned" to create a spike at a certain frequency. This allows the precised volume of the box to "louder" and have more punch.
A "T" line works best in a open are space like a SUV, Station Wagon, etc, due to its ability to reproduce a very accurate level of bass... The bandpass box for comparison works best in a sealed trunk. Since the back seat of a vehicle tends to block a lot of frequencies, the bandpass box has the ability to punch hard at a given range at the sacrifice of overall sound quality and accuracy.
SO T line is best for open air vehicles, not saying you can not use them in any other application, it just would be a waste of time effort and space to use this style of box in an enclosed space. Since the benefits of a "T" Line are robbed by the materials the sound is trying to push through.
Hope this information was helpful :)

It is all about port tuning. You can tune the port to a given frequency response ranget. Allowing you to flatten out any spikes in the low end. It takes trial and error and experience to get one right. When you do the results are nothing short of spectacular. It is not like setting up a system in a large room, the interior of a vehicle plays havoc on the sound quality of your system, so box "tuning" can play an important role in sound quality for automotive applications. In a perfect world you could stick all your speakers in the proper sealed enclosure and be done with things.
+Din Tjommi
You are correct, not all subwoofers work well in T line boxes. I have had some amazing results with Sundown Audios SA-8" and X-6.5 SW V.2, the excursion and overall design plays well with a T line and allows for a wide range of tuning. For real world example, my 2001 Golf GTI has an issue of a 54-55 Hz resonance. This causes a peek at the drivers location that gets "boomy" and it is so bad that it will drown out everything else when that tone is achieved. I have found that any sealed, ported, or bandpass box I have installed as not gotten rid of that over amplified 54-55 Hz hit. Just the cars design causes that spike in sound pressure levels at the 54-55 Hz. I have found that a single Sundown Audio SA-8 in a "T" line box tuned to 30 Hz facing backwards removes that spike in the sound from the drivers position in the vehicle. This has vastly improved the overall sound quality of the system overall. I no longer have to deal with ear bleeding spikes in the sub sounds. The added benefit I have found with the T line box is the lack of port "chuff", even at very high Hz levels the port "chuff" is near silent. The smaller overall size of the 8" subwoofer allows the speaker to reach higher in to the mid bass range then larger subwoofers. I have more head room to adjust my crossover points, allowing me to tune out some of the sub bass from the midbass speakers. Preventing any sort of low end distortions, and reducing the over all strain on the amplifier driving the midbass, mids, vocal and high speakers. Giving me a much fuller range of sound with far fewer peeks and dips in the audio range. Under white/pink noise testing I have been able to achieve near flat levels of sound sitting in the drivers seat. All while doing so with less then 2000 watt class. I have won a few competitions for sound quality in the 2k class, so I am pretty happy with the overall results.
COMPASBASSCLUB CHICALI try to use a sub with a QTS of .4 or lower. That's what helps give t lines the flatter response and shallow rolloff and tune it to the FS of sub. So try to find a sub that has an FS of the tuning you want
Jive Ass Turkey 👍
Doesn't the transmission line have to continually flare wider as it approaches the port opening? That what I learned anyway from the Loudspeaker Design Cookbook...
thats more like a horn enclosure, some t lines taper in some taper out
Hello there sir, how about with smartphone dock design....
Thats a bad ass box. Good job man. Do you have a store?
Thats an amazing box my friend! You should do a giveaway and choose me ;)
Hi, I bought a edifier s350db speaker system. I intend to remove the 8 inchs driver from the ported box and build a transmission line enclosure for it instead. But I'm worry that this driver might not be suited for transmission line if he don't have the correct fs, qts, qtc, vas, re, so on. Do you know of an ideal 8 inchs driver for transmission line available for purchase online that I can buy. I want to listen to my entire collection of rock from the seventees with low distortion tight bass coming from a single dedicated t-line subwoofer. As for the digital amplification of the edifier it is very well build. Keep on rocking till you drop as def leppard said in their pyromania album.
Hi. Quick question(s).
Is a subwoofer horn, basically, a T-Line with a larger neck and even larger mouth?
If not, then, what's the difference?
Hi mister, very nice video! very interesting.
this box designs recommended for sundown audio X-8?
Really thinking of building a t-line enclosure for one maybe 2 skar 6.5” subwoofers.
Fun little project for sure.
brian hilligoss let know how that goes
Kindly give me measurements for building a Kenwood woofer 3310 Cabinet.
Another nice video Mark.
+Robert Driesen thank you sir!
Would like to see you build a multi speaker - speaker box holding 4 12s. I've got one but would like to better my sound output and nobody has anything on 4 12s. I've search the Internet and it doesn't give you any guide lines on how to set this up except by speaker info, please help!
+Randy Hobbs I can do a design blueprint for you for this project. An easy to follow guide. Message me and see what else I have to offer at www.caraudiofabrication.com
Do you sell boxes? I'm very interested in a transmission box for a single 12
