Sound
Why the design works
The drivers, cabinet and crossover are designed to work together, then checked with measurements.
1
2
4
1
Custom waveguide
Helps the tweeter spread sound smoothly into the room.
2
4-inch woofer
Keeps the cabinet compact while still giving useful bass.
3
Passive crossover
Blends the woofer and tweeter for a coherent speaker.
4
Ported cabinet
Adds low-end weight from a small enclosure.
Measurements
Measured so you're not guessing
The response, impedance and directivity graphs show how the finished speaker behaves.
A compact speaker kit that measures properly, builds cleanly and works with normal hi-fi gear.
- Response checked
- Amp-friendly load
- Off-axis checked
For full measurement details, see the spec sheet. See the full spec sheet.

Questions
Before you start printing
Quick answers before you commit to the build.
Question Is this a good first speaker build?
Yes. It is designed for people who are comfortable with 3D printing and want a guided first speaker build.
Question Do I need to know how to solder?
You do need to solder, but prior experience is not required. The crossover and wiring are shown step by step.
Question Do I need a subwoofer?
No. Use them on their own for desktop, bookshelf and small-room listening. Add a subwoofer if you want deeper bass.
Question Do I need woodworking tools?
No. The cabinets are 3D printed and assembled with common tools.
Question What amplifier should I use?
Use a standard stereo amplifier or AV receiver with speaker-level outputs. The amplifier is not included.
