Hypercube Speaker Enclosure

Invented in the 1970s, the original inventors believed that regular speaker enclosures had several fundamental flaws that resulted in losses and inefficiencies to speaker drivers.
They believed that a enclosure in the shape of a rhombic dodecahedron acted as a form of resonating chamber, resulting in attaining high fidelity sound.

After taking a look at the expired patent and several other documents written, we just had to try make one for ourselves!

It was said that the best material overall to use was Rynite 545 and was injection molded to shape. This material is a glass fibre reinforced PET. We figured why not try 3D print instead!

To make it more compatible to most 3D printers, we tried in PETG, as well as PLA.

After pinching a generic 2.75inch driver from a cheap 5.1 sound system satellite speaker, we were blown away with how this speaker sounds. We compared them to some higher quality speakers and honestly, it would be very hard to tell the difference between them.

So give them a try!

We have included 3 enclosure designs.

• enclosure for the generic 2.75 inch Speaker (hexagon styled frame speaker)
• enclosure to suit a 3 inch dayton ds90
• stock hypercube enclosure (with STEP file)

All have 2 holes in one side for brass terminals to fit through, otherwise they can be drilled out to suit.
Uses 15mm speaker enclosure screws, or 6G Countersunk 10mm screws
