$100-$500

Project Description:

 The subwoofer for a 3D printed 2.1 audio system.

Design Goals:
The audio system was designed to be placed in a bedroom, with the least intrusive bookshelf speakers, a subwoofer whose design is appealing and functions for audio listening, and a shelf to display items.

Driver Selection:

 The subwoofer feature a Dayton Audio RSS210HF-4 8″ Reference Series HF Subwoofer. The choice was made based on the maximum dimension of my 3D printer bed, and the overall drive performance.

Enclosure Design:

The enclosure for both the bookshelf speakers and the subwoofer was designed to be 3D printed in a filament based on PLA and Carbon Fiber, a stiff material. Both speakers are sealed. A seal for the baffle was also 3D printed in TPU, as well as 2mm feet to isolate the abrasive carbon fiber feet from the floor.
The cost of filament for the Subwoofer is about $35.

Crossover Design:

The project does not have a crossover at the moment. I’m relying on the full-range drives used on the bookshelf, and the amplifier that includes subwoofer volume and filter.

Tips & Tricks:

N/A

Conclusion:
 
3D printing is a good alternative for people that do want to go beyond a cubic design.

About the Designer:
I built some speakers in my teens in the 80s. As I was renovating my home theater, I rediscover how fun is to build your own audio system.
