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.



Details that make a difference

The line array system, K&F SEQUENZA 10, proves convincing not only in its sound, but also in its handling. The fast and safe ‘Snap&Fly’ rigging system saves time and personnel without cutting corners on safety. All angle adjustments of the 3-point rigging system are pre-selected on the ground. When lifting, the units lock automatically and the line array is immediately ready for use. And all that with compact dimensions and a low weight. Sounds too good to be true? Check it out!

Directed power

An array of up to four elements generate a maximum sound pressure of up to 150 dB. Towards the stage, however, the system is extremely quiet. The K&F SEQUENZA 10 B subwoofer also blasts the powerful energy forward in a cardioid array and the rearward low-frequency part is eliminated. This generates a clearer and more distinct sound. On stage, however, it is much quieter and disturbing emissions in the surroundings are absent. More sound – less noise!

Patented Waveformer

The proven K&F patent is called ‘FLC’, which optimises the frequency distribution of both 10” chassis units. In the SEQUENZA 10 N/W line array modules, another innovative technology is used with the patented Waveformer with three 1” high-frequency drivers, which produces a plane wave front of up to over 16 kHz. With the unique tweeter resolution and the long throw, the system is impressive during every use. Or, in the words of the renowned trade journal ‘Production Partner’: “Thanks to the K&F SEQUENZA 10’s all-around perfected design, the system delivers a performance that can, without exaggerating, be considered as the cutting edge of feasibility in today’s state of technology.” In a nutshell!
