Explore the project
The speaker you’ll build, its requirements and the original project guides.
Heads-up: this is a big build with multi-day print times, so clear your queue and stock up on filament before you hit “Start”.
Build a center speaker that makes movie dialogue pop and explosions hit like thunder.
Designed to crown the front stage of any serious home theatre rig, the Illuminate 7c is a true three-way beast: silky highs, hyper-detailed mids and dual 7-inch woofers that dig deep—all wrapped in a 3D-printed cabinet you craft yourself.
Great Sound
- 28 mm soft-dome tweeter for razor-sharp top end
- 52 mm fabric dome midrange that keeps voices lifelike and locked to the screen
- 7-inch low-distortion woofer delivering muscular, room-filling bass
Crossed over for seamless hand-offs, every driver plays in its sweet spot, so action scenes, whispered secrets and orchestral swells all land exactly as the mix engineer intended.
Large Format Center Channel
At 250 × 265 × 494 mm (H × D × W) the 7c is unapologetically substantial—big enough to go toe-to-toe with tower mains
Limitless Customisation
Choose from thousands of 3D printer filaments to design a speaker that’s uniquely yours. Whether it’s bold, subtle, or somewhere in between, the Illuminate 7c adapts to your style.

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.
