Officina Tron Audio F812A dipole speakers: a wideband speaker and a pair of guitar basses in a modular housing
The F812A dipole acoustics of the Swiss company Officina Tron Audio are made in accordance with the company’s modular concept. Such a column is assembled from three square sections. At the top there is a driver of medium and high frequencies, below-two bass players. In theory, the number of sections can be changed (how exactly-Officina Tron Audio did not report and offered to address such questions personally).
Three square flat screens — one speaker in each-are mounted on an aluminum profile frame. The frame itself was made triangular, rigid and easily disassembled.
The 8-inch wide-band speaker installed in the F812A speaker is a product of the Chinese company Lii audio called Fast-8. On the basis of this driver, as stated in its documentation, you can even make a full-range speaker system.
