Build plans for the pipe speakers

Are these pipe speakers a meme build? Maybe. But that doesn’t mean we can’t make them sound as best they can. Not going to lie, I’m quite impressed with the bass response of these tiny speakers. I’m not going to give too much details because I’m assuming you watched the YouTube video. The design assumes the speaker box with just the dual full-range drivers. However, I’m also going to include the MTM design, so, with the added tweeter and crossover. Depending how much effort you want to put into this speaker, you can choose your difficulty level.

Pipe fittings

Let’s start with the pipes. We’re building some pipe speakers after all. Here is what fittings you will need:

  • 3 Tees (Diameter 3″)
  • Two 90-degree elbows (3″)
  • A 3” connection tube
  • One 3″ Tee with a 2” reduction
  • A straight 2” pipe. The smallest one you can get, because you are going to cut it very small anyway.
  • A 2″ 90-degree elbow
  • Five 3” caps

If you are doing the MTM build. You will also need an extra 2″ straight pipe, because we need a small bit of it. I’m not going to link any stores because every country has their own “home depot”. Pipe fitting may vary in dimensions from manufacturer to manufacturer so bear in mind that your speaker may look slightly different.

Audio Components

There are only a few audio components in this project. Here is the list of audio components with the respective links. The links are affiliate paid links, and I do get a small comission if you make the purchase without any additional cost to you:

If I haven’t mentioned it in the video, the bass speakers are wired in parallel.

Crossover components

If you do decide to build the MTM pipe speakers, you need to implement the crossover. Here are the crossover components. The links are affiliate paid links, and I do get a small comission if you make the purchase without any additional cost to you:

Here is the crossover diagram:

S1 is the tweeter and S2 are the 2 mid-bass drivers wired in parallel.

Pipe speakers frequency response

Let’s take a look at the response of the pipe speakers with and without the crossover.

Pipe speakers without crossover

Just above we have the response without the crossover and below we got the response with the crossover and tweeter in place.

Response with crossover

The crossover flattens the response in the top octaves quite a bit. As a result, the cone break-up at 7 kHz and 12 kHz are no longer there and the response stays flat till 20 kHz. This may or may not be important to you. In conclusion, you be the judge if you want the tweeter in this pipe speakers or not.
