@@SoundBlab I used a ceramic sewer pipe for a 25cm diameter woofer, 70ish cm high, 40cm total diameter. They need not be too large if you can make the material dead. Sewer pipes can be had here and there for bargains, unused, maybe where you are too? You could also optimise by floor size, I have another sewer pipe, but plastic (other materials too heavy), it is cheap, only 25cm total diameter, and comes in standard length of 5,5m. So, I cut it down to 2,40m exactly to me ceiling, now I need a way to put it upright and be stable enough. IIRC 90cm or so of 10cm reflex pipe will put me at up to 18Hz flat. Big pipes are easy and good. For subs anyway.
@@OlavAlexanderMjelde Using a ceramic sewer pipe? Unlikely. Plastic sewerpipe? Probably if you have the connector pieces but no idea how that will affect the sound, sharp corners, and 25cm across still means a rather high couch. I optimized for least amount of floorspace, to just take in vertical space instead, not tiny size in general because it really is not.
i really do appreciate those tang band subs, i used to have a z2300 but the amp died and then a few days ago i decided to build a new enclosure for it and it bangs. The sub that was used in the Z2300 is the Tang Band W8-670Q which is now fitted into a ~100Liter enclosure tuned to 30Hz which gives me a F3 of around 27Hz and a relatively flat respone
would have been great to maybe use a di-pole driver to see how much audio spectrum you could cover with just that enclosure. Great build BTW, always enjoy watching your creative new projects.
I should know better to watch how I say things. I understand what you're saying, and I understand the complexity of tuning transmission lines. Thank you for highlighting my failure in the english language.
@@SoundBlab you can also take a cut sheet to your timber merchant and they will pre-cut stock to size for you to an accuracy of plus minus a couple of mm, which can then be flush trimmed to final size with a router and a metal guide rail if you need absolutely hair-splitting accuracy.
nice build, just a tip for a box transmission, the port needs 45 degree angles at each turn (use wood), to guide the pressure wave used to prevent pressure bounce back into the t-line.
Thanks. I would not go so far as to say that it needs it, but it will surely help the flow of air. There are many highly regarded commercial designs out there that do not always implement this, and they seem to still function as intended. I get what you say though 🙂
Actually, the corner pieces are usually cut to the size to make the bend the same surface area as the line. An ideal corner piece would therefor me concave to keep the perfect surface area. :)
Made my first with some old tear down parts of old stuff, not as small, due to needed to be at least 12”x14”x and went with x 10 sidewall which placed ext. wall and act as side ports for surround acoustic with additional top ported tube. I have very minor knowledge on boxes or properly distributing sound. The 4” micro sub is in its own separate box within the box as sorta of a double boxed concept acting as a double semi compressed bass -air-per-cubic ft. Which i was iffy about. And only using 2 smaller 3inch full range audio speakers in front of box and i only designed 2 split sound walls to control the acoustic to ported sidewalls , which front to rear go 7 inches to back- once again i have no clue what i am doing , to know whats best. Lol just and idea of how i thought i wanted it to work with lil to no knowledge . Let me tell you something though. The quality of 300deg. Sound shocked more than just i ! They bass shakes whatever you did not know was loose in the house or area. The neighbor from 3rd floor , i do not even know , as i walked out to put into car before work to get some paint on it , asked if that was playing on and off last couple days? I replied yes as i was checking to see sub hertz range for 6-7 min. Each time. He replied -wth ! That is one bad*** loud box , it can shake somethings in here and i thought it was someones subs in a car. Lol -note these are very newly built solid and very quite apartments and that was the 3rd floor. My wife won’t even let me play it in the house . But i did noticed the 2” x1” side ports built in sidewalls were not enough and i thought would be too much or plenty for the small pre-boxes sub at base of box , but they were actually not enough i found out later on accident . So i ended up putting a flush port tube at the rear top of box and that increased bass and the bass quality of surround as the speakers were already. I think the reason for this was , that on the sidewalls i decided to close the side ported areas off box with audio mesh for a nice, clean look and it cut down on the air to be able to exit box as much as did before and compresses against self. So the ported tub on top helped not only get that back , but made it even better in all aspects. Never expected that lil sub to need so much air . Given its pre-box size is 12x14x3.75
It's really flat in the responce, smooth and tight.... is there a video on small battery powered amps as I'm thinking of a portable system with a extra amp to power this when there space and time for the exta subwoofer... Intresting for live song making in the woods or on a mountain
Nice video if u can plan a slim hideaway sub so that the home minister doesn’t complain. Would be great. Also slim line array using Tang band sound modules
That looks and sounds great! I love TangBand subs, i have 2 Tang Band W6-1139SIF 6-1/2 subs in my car and they sound good but i know they could sound better with the proper box. I know nothing of subwoofer box design, i just tried different box sizes and different slotted port lengths until i thought it sounded good. It would be nice if someone would design a box that i could make.
PDRIFT86 I just put those same speakers in a box in my truck. Somewhere around .35-.50 cubic feet per driver is sufficient and a 2" port that's 10" long will tune it to about 35 hz. I used a 2" PVC elbow for the opening and 2" pipe connected to it for an additional 6" to get the 10" line. I stuffed it moderately, with about 6oz of polyfill. Sounds 3x better than just having them in my doors.
You can check out WinISD From what I hear it's what most use for box building All you need is the specs of the speaker and the desired frequency, then input it into the program.

@@jimcatx3090 you would be surprised at the bass extension of some small woofers. Go on parts express and look, Dayton audio makes a 4 inch neo woofer with 5mm x-max. This won't compare to a 10 or a 12 inch sub, but for a desktop setup it's pretty good.

Hi there. I like all of your videos since you explain things in very easy terms to understand, particularly, for a newbie, like myself, and which has led me to start building my system from scratch. One of the things I'm planning to build is a Transmission Line enclosure. Got a question - let's say my target frequency were 35Hz using a driver with a frequency response of 44Hz - 22000Hz. So, 35Hz is below 44Hz. Will my T-Line enclosure be able to hit the target? Or I do I need to set a new target at a point no lower than the one part of the driver's frequency response? Is there any restriction aside from the length of the tunnel and its cross-sectional area? Can it be tuned for any given frequency regardless of the speakers frequency response? Regards and, please, never stop making videos.
Thanks man! It's difficult to say. It all depends on the driver specifications. You can go lower than the FS of the driver, but would not push it beyond 5 or 10 dB. The driver will run out of steam and you will get what we call a shelved response in the lower part of the frequency response. This transmission line calculator will help you to determine the ideal response: www.mh-audio.nl/Calculators/TML.html
Hey soundblab! Your driver fs is 35hz. So the lenght of the port should be 96 inches to produce 35hz and the port should be continuous. But in your design the port length looks less than 50inch and is also not continuous.. can you please explain this?
Can't remember exactly what the line length ended up being, but often by playing around with the line length and placement of the driver, you can smooth out the response and get a similar result to a longer line.
That is not entirely true tho... Transmission line enclosures rely heavily on stuffing to absorb the 'higher' frenquencies. An unstuffed transmission line sounds quite rubbish tbh. Very undefined and unbalanced. I've tinkered quite a lot with these types of enclosures, and this is what I was able to conclude.
amazing bass for the size. my first DIY sub 15 years ago is a Sony 12inch, around 380wrms. It was too much and unwieldy, I'd be happy with this 4inch. 🥹
Very well done, I listened with a nice pair of headphones and it has an impressive range. Thank you for sharing!

Forgive my ignorance, I'm new to the music sound quality scene. What is the purpose of the white matting?
Jeremy Knight to reproduce bass frequencies clearer as the bass won’t echo as much and over all will just sound better 😀
Sound dampening. Is causes sound waves to travel more slowly in the enclosure which simulates having a larger enclosure.

Can't remember exactly what the line length ended up being, but often by playing around with the line length and placement of the driver, you can smooth out the response and get a similar result to a longer line.
blocking air hole with this fiber foam is a mistake. try passive radiator or just free up the air way to make bass more punchy at low end.
