Tight, Punchy, Well-Defined Bass


F218 MkII is the latest iteration of Funktion-One’s long established and highly respected dual 18” bass enclosure.

It is the result of many years of research and development into bass loading techniques. The evolved F218 MkII is highly regarded for its extreme robustness and delivery of tight, punchy, well defined clean bass from a relatively small and very manageable package. F218 MkII brings refined loading, improved heat dissipation and an updated driver specification.
