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.

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:
Been wood working and messing with electronics / audio since a kid.
