The DALI ALTECO C-1 is truly a multi-purpose speaker. The perfect fit for adding height information to a surround setup or taking the role as an out-of-the-way stereo speaker. By designing the crossover for stereo use and by keeping a strict focus on DALI sound design principles, we have created a speaker that delivers believable height information from Atmos, DTS-X and Auro-3D movies.
