Explore the project
The speaker you’ll build, its requirements and the original project guides.
Build a center speaker that punches well above its weight.
Designed to slot neatly under your telly and lock in with the rest of the Illuminate family, the Illuminate 4c gives dialogue razor-sharp clarity and smooth dynamics—all from a low-profile 3D-printed enclosure you build yourself.
Great Sound
A premium 28 mm soft-dome tweeter handles the highs with surgical detail, while dual low-distortion 4-inch woofers keep mids rich and voices lifelike. The result? Seamless, cinema-grade sound that’s fully timbre-matched to every speaker in the Illuminate line-up.
Low-Profile
At just 109 × 255 × 320 mm (H × D × W), the 4c slips under most TVs, inside media cabinets, or across a desktop without blocking the screen—or looking like an afterthought.
Limitless Customisation
Pick any filament you like—glossy, matte, wood-filled, glow-in-the-dark—then print the 4c in colours that match your room (or clash on purpose, we won’t judge).
Easy to Print and Build
From sourcing components to final assembly, our detailed guides and validated STLs make the process straightforward and enjoyable.
Exceptional Value
Enjoy sound quality that rivals premium off-the-shelf speakers at a fraction of the cost. Build it yourself and own a speaker that truly stands apart.
Printable Crossover Board makes positioning components effortless.
Labels and guides help eliminate wiring mistakes.
Filament required per speaker: ~1900g
Minimum printer build volume: H250xD175xW110mm
A few things to know
How do I receive the plans?
Your digital files are emailed after checkout. Download the files and read the project guides before starting your build.
Are any physical parts included?
No. This is a digital plan. You source the components, filament and hardware separately, then print and assemble the speaker yourself.
Will this work with my printer and parts?
Check the printer build volume and component list for this specific project. Requirements vary between designs, so confirm that your printer fits the parts and that you can source the listed components before buying.
