The Optimal Audio Cuboid 8 White is the white-finish version of the Cuboid 8, a two-way passive loudspeaker pairing an 8-inch LF driver with a 1-inch compression driver on a rotatable horn. It handles 200W (AES) and reaches 115dB continuous, for installs where a black cabinet would stand out against light walls and ceilings.
