In the 1980s Funktion-One's Tony Andrews had also pioneered work on the development of the first widely used 21'' (6'' voice-coil) loudspeaker. This provided the low end for his highly regarded system design of the time, which was used on world tours by groups including Pink Floyd and Dire Straits. In 2006, with Funktion One's access to advanced materials and Andrews' heightened understanding of loudspeaker and enclosure tuning, his original 21'' concept was due for a revisit. This work has resulted in the F221 with dramatically increased performance including a double voice coil for maximising power input.
The F121 single 21'' bass enclosure is a highly attractive proposition for applications desiring access to Funktion One's incredible 21'' bass technology but in a smaller form than its double 21'' counterpart. The enclosure and Funktion One driver have been beautifully tuned and matched to deliver a highly accurate (and even addictive) bass experience which not only gives the listener the anticipated depth and physicality of bass but combines this with unprecedented upper bass speed and precision. The F121 can be used singly or in multiples with Resolution systems or Dance Stacks. A self powered version (F121A) is available fitted with the excellent A6 amplifier module which has enough power to drive an un-powered slave - all enclosures can be retro fitted with the amplifier modules if required.
