Infrabass 218

Funktion One infrabass 218


The patented Infrabass 218 is a bass loudspeaker enclosure covering the octave from 30 to 60Hz.  It delivers smooth, deep bass for a powerful sonic experience.  Its proficiency through the lowest bass octave can be used to extend the bass delivery of any Funktion One system.  Due to the very large current requirements of extreme low frequencies, only amplifiers with high calibre power supplies will realise the full potential of this product.  The optional Double Infrahorn, shown overleaf, can provide significant additional loading for a pair of Infrabass 218s in applications with extreme bass requirements.
