Tonnara High-End Audio System


Tonnara consists in five modules per channel :
- Two bass units, that is four 13’ (33cm) loudspeakers, in double parallel push-pull, equivalent to a single huge 26’ (66cm) driver. The speed of the moving coils is controlled by the servo processor.
- Two low-midrange units, that is six 6’ (16,5cm) loudspeakers, with very high acceleration factor.
- A coaxial horn high-midrange-treble unit, low diffraction, constant directivity, compression midrange 4’ (100mm) titanium dome, compression 0,63’ (16mm) ring tweeter. 88lbs (40Kg) of fine sand from Tonnara beach damps the midrange horn.


For each channel, a 7 ways strand, that is a 2x25mm2 global cross-section + symmetric connection for feedback processing.
