What are they?
KOTKA panels are next-generation sound absorbers with a unique and innovative design that allows to be used as standard sound absorbers or as bass traps; they have three mounting options: two flat positions and one angular position. Their studied shape creates different air cavities, plotted to obtain an extraordinary acoustic performance. When mounted in the angular position, the variable air cavity formed converts the Kotka panels into spectacular bass-trap absorbers.
They are manufactured with our special ZHFR acoustic foam, with an improved porosity coefficient to obtain the best acoustic performance in the market.

... inspiration
Its design is inspired by the flight profile of the Iberian golden eagle, in homage to this endemic bird which inhabits the peninsula.
What is the application used for?
It is used as versatile soundproofing treatment for rooms that require both acoustic and aesthetic results.
They offer the option of using a single product as an absorbing panel, to control early reflections and reverberation time at medium - high frequency, or as a bass trap for controlling low frequencies.
Absorption treatment for: control rooms, recording rooms, rehearsal rooms, radio/TV broadcasting studios, home cinema...
