Project Description:
The DARS Cube is a portable speaker that’s easy on the eyes and ears.

Design Goals:
The goal was to design a portable Bluetooth speaker with a clean look that will be used mostly at low volume for long listening periods (workday).

Driver Selection:
Dayton Audio RS100-4 4″ Reference Full-Range Driver 4 Ohm
Part# 295-378

Enclosure Design:
6.5″ x 7.5″ x 6.25″
1/2 Pine Enclosure
3/4 Poplar Baffle
Metal Plate for switch, volume and 3.5mm jack
Also as speaker out connector to run additional passive speaker

Enclosure Assembly:
Mitered sides, glued and ran through the router.
Lots of sanding to bring out the wood grain.
Front Baffle was left natural and sealed with wax finish
Top/Sides and a mix gray enamel paint mixed with white stain. Weird, but looks really nice.

Crossover Design:
Full Range with -4db of baffle step compensation.

Tips & Tricks:
Used threated inserts to make removable rear panel. Makes swapping parts and adjusting much easier.

Conclusion:
Overall really like the look of this speaker. I’ve used this mostly listening to music while working. Small enough to fit on a desk and sounds great.

About the Designer:
