Dali Alteco C-1
Compact Dali speaker dedicated to Atmos, DTS-X and Auro-3D height effects, to enhance an existing home cinema system.
Description
The Alteco C-1 is a compact speaker from Dali, designed specifically to reproduce the vertical dimension of sound in Atmos, DTS-X and Auro-3D formats within a home cinema installation. It does not replace a main speaker but complements an existing system by providing height effects, whether through ceiling reflection or downward diffusion depending on the chosen installation.
The filter of this speaker has been designed for classic stereo use rather than for the non-linear equalisation specific to Atmos-certified speakers using HRTF (Head Related Transfer Function) technology. This design choice allows the Alteco C-1 to be installed in several different ways, without being limited to a single upward-firing role, with height processing being handled by the amplifier when required.
With dimensions of 160 x 190 x 225 mm and a weight of 2.8 kg, the Alteco C-1 is aimed at home cinema enthusiasts wishing to incorporate height effects without adding excessive bulk, in a room where space for additional speakers is limited. Its mounting versatility makes it a sensible choice for complementing an existing setup rather than forming the core of a system.

What to check before buying used
When buying used, it is worth checking the condition of the driver surround(s), which can stiffen or crack over time and affect low-frequency reproduction. Checking the connectors and terminals also helps ensure a reliable contact, while a listening test across the entire stated frequency range helps detect any distortion or imbalance between the two speakers of a pair.
