I started the self-construction of a low-cost acoustic speaker to be used with T-AMP + DAC-USB + PC, I ended up patenting a new type of ultralight loudspeaker “665g”. Robin srl has filed the patents of a new technology for audio speakers. The first prototype “665g” in a desk configuration is visible on the website robinsrl.it. Replication for personal use is allowed for DIY.
The main technical characteristics of the 665g loudspeakers are:
- emission of coherent and delayed secondary sound waves without the use of electronic circuits and / or multiple loudspeakers,
- single driver with Faital Pro 3FE25 wide band speaker,
- omnidirectional in the horizontal plane,
- no internal sound reflection.
The project is still evolving. The part that generates the sound is well defined, for over a year the waveguide (the tube) is not modified. The space location is still changing, the current form of the desk-fixing bracket was first tested in November. Anyone who wants to hear the sound reproduced by the 665g speakers must do so with the spirit of the experimenter. A DIY can assemble the couple with a total cost of some tens of euro. Who is willing to finance Robin srl can order a prototype for 200 euros. Who is in the area of Sassari can get in touch for a demo.
