Loudspeaker Products


The perfect loudspeaker series for elegant, architectural room integration and for mobile use. Sophisticatedly developed with all-round convincing sound characteristics, even in acoustically difficult environments.



With the K&F SPECTRA 212i, KLING & FREITAG expands the existing SPECTRA 212 line with a versatile installation model. Created specifically for wall and ceiling mounting, accessories further augment K&F SPECTRA 212i’s versatility, allowing it to be precisely aligned to all listening planes, either singly or in cluster.

As with all the models in the SPECTRA series, the K&F SPECTRA 212i includes the patented VariQ unit, enabling easy conversion from point to line source. The two different radiation characteristics N (60° x 30°) and XW (120° x 30°) enable an exact adaptation to the local conditions. K&F SPECTRA 212i lends itself to integration within architecturally demanding environments, or placed more prominently, bringing forward its unique visual profile. Besides the standard black colour, K&F SPECTRA 212i is available in all colors within the RAL palette on request.
