Why specify it

A 360 mm sphere covers a terrace, a garden room or a lounge without a listening axis to protect. Two base designs let the same object sit on a floor, a plinth or a planted edge.

System role

Available in full-range and subwoofer configurations. Amplifier channels, DSP and crossover settings are decided per project.

Project imagery

  • A Puglian courtyard at night with a lit pool between stone arches, a cube loudspeaker on a lit open base beside the seating and a spherical loudspeaker on a plinth across the water.
  • A Mediterranean terrace at dusk with an infinity pool over the sea, a stone cube loudspeaker on a lit open base beside a daybed, and a spherical loudspeaker further along the terrace.
  • A coastal villa interior open to a sunset sea, a spherical loudspeaker on a low stand at the left and a marble cube loudspeaker on a lit open base beside the seating.

Installation

Indoor or outdoor systems

This is a designed audio system

Selecting the visible loudspeaker is only one part of the work. Each project requires decisions about acoustic coverage, full-range and subwoofer roles, amplifier channels, DSP, crossover settings, cable routes, mounting, lighting and finish. Nico supports architects and designers from concept and specification through coordination, commissioning and final calibration.
