Manufacturers Description

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.

Product Rating

“By far the best service I’ve ever experienced. I was importing a product to Canada and the whole experience was quick, easy and seamless. These guys really care about running a good business. Not to mention the price was cheaper than the stores here even after importing. Definitely will do more business in the future.”
