Hi everyone! Thanks for tuning in to this project of mine, I hope you'll like it and perhaps try to build it yourself! As always I have included a detailed list of modified plans, a wiring diagram, product links and much more for your information on the build. I encourage you to check my video first before diving in to the build. Let's get started!
The main goal for this project was to build a subwoofer that would play pretty low and would have an integrated amplifier capable of powering two other speakers all cramped inside a relatively compact enclosure. Fiddling around with various woofers in winISD I have decided to go with a Tang Band woofer and a 2.1 amplifier for best results. As you can see by the graph, the enclosure is tuned to 43Hz and has an F3 of around 37Hz which is pretty amazing considering the price of the woofer and the compact enclosure that it needs. Of course it will not play that low cleanly due to port noise and possible chuffing but will still perform great.
As you can see below, I have attached a set of plans, metric and imperial for all needs. You will also find the template for the control panel in the end of the plans which you can print out and glue to a piece of wood to have an accurately made control panel. Feel free to download the plans and the wiring diagram for your personal use. I would love to see how your project turned out!
Note that I have modified the plans therefore the speaker may look different than in the video. I have modified the plans to use less components and be easier to build with an overall better design.
You may have noticed that there are less components in the wiring diagram compared to the video. I did so to reduce the number of the components used and simplify the overall build process of the subwoofer. I have also used a similar amplifier that has the Bluetooth built in so that you don't need a separate module for that. Here you will find the complete list of parts and tools used for the build. Note that the parts can be ordered internationally.
I am more than happy this subwoofer turned out. It packs a punch and is definitely powerful enough for home use. It can also output plenty of power to various different speakers for the best listening experience.
I hope you liked this project and perhaps learned something new! My hopes are that you will give this build a try yourself and post it at the end of the Instructable so that me and others can admire your work! Feel free to post any questions or comments down below, I will try my best to answer them.
Thank you for tuning in to this project of mine and I will see you on the next one!

Millwork is nicely done, virtually the same as i would have done. Try using shellac as a sealer as it will not cause any swelling of particle board or MDF. Just a handy hint.😉 Dry & ready to handle in 10 to 15 minutes or less.

Holy mackerel Brother. Awesome job, I felt like I was watching how its made. How To...Anyone with all your equipment already knows how to build it. Im looking to do a stand alone but i was going to tart up some old car speaker stuff and using no jigs or fancy equipment. Dont get me wrong I build systems for homes and cars and in order to be productive we build boxes sand edges and cover with material, your build is geared more for master tinker guys. With your skills make a box with old parts and minimal time and public would not get discouraged

[@slepix]

One of the rare builds on YT I actually like. Kudos. TIPS: Add some Sonofil (or something similar) in the box. It will "increase" the box size and make the woofer play a bit lower and softer(but not muddy). Additionally, it also helps with standing wave dissipation and tends to help with some potential port noise. Also, make sure that the intake of the port (one inside the box) has at least the diameter of the port of distance between the wall facing the port input. That greatly reduces port noise(if you have any). So, if your port diameter is 8 cm, make sure that the intake is at least 8 cm away from the box wall facing the port input.

Dude thats a very loving job you've done building that Sub but I would've put the power supply on the floor of the unit because heat will over time melt the tape and I suspect the weight of the power supply will cause damage and you grief having to undo your excellent work. And I would use 8 gauge cable for the signal wires to your other speakers. Its a wonderful thing seeing someone taking pride in their work and sharing the results.

You did a lot of work here but there is a lot going on that is not so great. Maybe you could watch some threads on audio forums. Not trying to be an a-hole, but seeing a lot of work and a not so great outcome. Things that could be better is the diameter of the port and internal placement, it is too close to a wall and the air velocity is too high. You should always place the amplifier and power source on the bottom and mounted with screws. It also looks like you pushed the power cable socket in without an adhesive. It is so close to being really good, just for a few details. I do hope you will continue because you have talent enough 👍

[@suzesiviter6083]

The distortion figures for TPA3116D are around about 0.2%, which is perfectly acceptable below 100Hz as hearing is less sensitive to distortion there, BUT the IC is only capable of 50W into 4R, which means you need an optimum box size for the driver you are using, otherwise you will get massive amounts of excursion and little actual bass output. In other words you cannot use a small box with such an underpowered amplifier. Is your box size calculated on the Thiele Small Parameters for optimum ported? Does it shake the room?

I have set of 1x600W subwoofer , 1X 800W subwoofer , 3X 60W mid-range speakers only for mid ( loud asf ), 2X 40W and 4X 20 tweeters.
