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!

Step 1: Design Goals and Plans

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.

Great job, Thanks! Really good stuff!
Add a power-saving sleep-mode circuit that will auto-sleep after 10 mins (or ?) of inactivity while using a very small power to listen for audio I/P signal to power-on the sub back to life. Very professional and impressive wood-work too!

Great project. I think I'd look for a more efficient sub, although all the other specs, especially Xmax look great.
Donny Terek (author)  Steve Dallman4 months ago
Thank you! I chose this sub to be able to use it in a small enclosure producing great results.

Hi, what a great looking project with a nice clear set of build instructions.
Can you please explain ,what is the purpose of the ports and the piece of pvc pipe? is it for ventilation? Thanks for a great job!
Donny Terek (author)  Roy L Miller4 months ago
Hi, thank you so much!
The purpose of the ports used in many speakers is to improve the efficiency of the low frequencies produced by the speaker. Generally speaking, it helps most speakers play into lower frequencies. The length and width of the port needs to be calculated according to the speaker used in the enclosure.
I hope that answers your question!
