Symbio Design Loudspeakers by Jerry Koza: Alpha, Beta & EggO

The Alpha or Alfa (sic):



The design of the Alpha loudspeaker system is based on a baffle made from laminated composite. A bass-reflex tube is made the same way and, after the manufacturing process completion, it becomes an integral part of the baffle.



In addition, the bass-reflex tube orifice shape prevents the turbulence generation with air circulation in the tube, when a higher sound volume is set, which very often adversely affects the systems sound character and brings undesired noises into the performance. The shell is made with laying stress on the standing waves elimination without a single joint, so we eliminated pressure losses. The selected construction provides high shell rigidity with a big inner acoustic attenuation.

The Beta:


Upon customer’s request, it is possible to individually change the standard high-gloss snow-white surface finish, which comes from ALFA, for any other colour of the RAL colour palette. Generally, the model is also supplied in black and silver colour.



The Beta loudspeakers are designed to be put on a table top or any other suitable place, including floor. We are also preparing light in-wall or ceiling installations. The minimalist solution assumes a simple connection to your audio system using the loudspeaker cable, which is the part of delivery.
