All the speakers in the Cuboid range are full-range, 2-way loudspeakers. This
means that they have a high frequency tweeter loaded onto a waveguide, giving
increased efciency and directivity, and a low-frequency cone driver.
The loudspeaker is fed with a full-range output from an amplier and an internal
electronic cross-over network divides the signal between the high and low
frequency drivers.
