• Dual 5″ Polypropelene woofer
  • Kapton ribbon tweeter
  • Wide horizontal dispersion
  • Designed to be installed in semi acoustically treated living rooms
  • High gloss piano finish
  • Close coupling wall mounting arrangement


The compact Alto has a 180° dispersion to create homogeneous room reflections, thus increasing the spatial effect without damaging the localization of the source by achieving a linear spatial energy pattern.

The semi-circular cross section allows the Alto to be fixed on the walls creating a virtual unique source without any destructive mirror effect in mid-high frequencies.

The Alto cabinets are equipped with rear spikes for wall mounting. These rear spikes create a cross-coupling with the wall.

The ultra-light ribbons used in the tweeters are capable of very high acceleration and extended high frequency response.

The Alto comes in a very high gloss piano finish or a natural wood finish which blends elegantly with most living room interiors.
