I have build speakers and amps for about 25 years, and after I got into 3D printing, I decided to make the enclosure as a 3D print.

After a lot of testing to get the right shape and thickness of the walls, I was sold and haven’t built any speakers since in anything other then 3D print.

The egg shape has always been one of the holy grail’s of speaker cabinets, and with 3D printing this is much easier to produce then in wood.
