Getting Started

Getting into DIY audio can be complicated and daunting. Here at Polymate3D, it is my task to empower you with a platform where you can get your legs, and then pursue whatever routes you desire!

With this in mind, here is my advice to help you start

Step 1) Stick to a pre done design

Yes it may sound dull but it is the best advice to get going. Many of the speaker drivers have various cabinet designs

Step 2) Decide what size speaker you want

Do you want something small for a laptop, a full blown bookshelf speaker, or even a full blown floor standing arrangement? Here are the rough sizes depending on the application:

A Portable Bluetooth speaker will usually be between 0.3L to 2L per speaker driver

Laptop speakers will typically be around 0.2L to 1L per speaker driver. Desktop speakers will be around 1<4L.

Soundbars typically will be around 0.5L to 2L per speaker driver, and will run 4 or more

A proper bookshelf speaker will be around 3L at the smallest, and will go all the way up to 15L

Looking at going all out with a floor standing speaker. These can vary wildly from 20L all the way up to 60L and beyond for just the single speaker driver.

Step 3) Are you 3D Printing, or woodworking?

3D Printing for the novice will be the simplest as the cabinet can be made to a exact standard without any help. If you are new and not worked with wood but wish to do this, please seek many places online which can help with this

If 3D Printing your own speaker drivers and cabinets, please see the ‘Print Settings’ page through the button below

Step 4) Does your target size fit with Micro or Macro?

Micro is small full range driver, built to work with designs between 0.15L and 1.5L per speaker driver.

It has a easier assembly process, a expanding variety of cabinet designs, and whatever motor is chosen can be reused later with a more complex speaker driver!

Macro is a slightly larger full range driver which will come late 2022, and will work with designs from 0.5L to 3.0L

If Micro does not match your needs, you can check out the main series of speaker drivers from Polymate3D

Step 5) Picking the magnet motor

Unless your looking at building a speaker for a cabinet 15L or more, the driver of choice will support all Entry & Mainstream motor designs:

Entry Motors

Entry motors will give you a reasonable performance level below a DIY audio build, but matching your typical off the shelf desktop and hifi speakers. They will work in sealed speaker cabinets along with aperiodic (Leaky) cabinets.

The 4 motors are split into 2 categories. 1 being best value for money, and the other for low weight where this is important.

Prices for entry kits start at £8 before shipping and makes a pair of speakers.

Mainstream Motors

Mainstream motors enable the designs to match industry standard DIY audio drivers in frequency response and distortion. These motors enable the speaker drivers to work in sealed, aperiodic, ported & passive radiator cabinet designs.

The 3 mainstream motors follow an upgrade path with increasing power output and handling.

Prices for mainstream kits start at £20 before shipping, and makes a pair of speakers.

Kits are available for all magnet motor designs to make sure you get the correct parts first time, and helps support the project with its ongoing development.

Step 6) Verify your choice and go!

Last stage before committing is to verify you have picked a speaker driver you like and a cabinet design which goes with it. Any questions or concerns, feel free to reach out to me on Twitter, Facebook or via email which can all be found at the top of this page.

I wish you the very best on your venture, and hope this guide was of help to get you there. Hope to see your build soon!
