F218 mk2

Funktion F218 mk2


The F218 Mk2 is the latest iteration of Funktion One’s long established and highly respected dual 18” bass enclosure. This is the result of a holistic approach over many years of research and development into bass loading techniques. The evolved product is highly regarded for its extreme robustness and delivery of tight, punchy, well defined clean bass from a relatively small and very manageable package. It has often been emulated but never equalled.  The F218 brings refined loading, improved heat dissipation and an updated driver specification.
