Funktion One F55

Funktion One F55


The F55 ultra-compact loudspeaker is the perfect choice for applications requiring wide-dispersion near-field coverage including bars, theatre front-fill, under-balcony and domestic use. This high sensitivity enclo-sure delivers good vocal intelligibility with excellent clarity and imaging detail; attributes rarely present in compact loudspeakers. Dual 5” drivers manufactured to Funktion One specification have been carefully optimised with the enclosure tuning for use without processor or system equalisation for natural simplicity and high performance. In common with the F81, out of operating band low frequency protection is incorporated. If additional bass reinforcement is required our smaller bass enclosures including the MB112 and MB210LP make the perfect complement.

Funktion One F215

Funktion One F215


The F215 is a double 15'' bass enclosure which utilises the same bass loading technology as Funktion One's highly regarded F218 with similar performance characteristics. It is pitched higher giving slightly less low end extension but even tighter and punchier upper bass. The F215 can be used to great effect as mid-bass in systems with Infrabass low end extension.



Funktion One F118 Mk2

Funktion One F118 Mk2


The F118 is the single 18” version of the F218 for those who require a compact horn-loaded enclosure. In common with the F218, the Mark 2 version brings refined loading, improved heat dissipation and an updated driver specification. It provides strong, well-defined, clean bass from a small and manageable package. The F118 can be supplied with an optional pole mount for use with a wide range of mid-high products including the F101, F88, R1 and R2SH. An installation version of this enclosure with flying points is also available; which can be effectively used to provide bass extension to products such as the AX88.



Funktion One F221

Funktion One F221


Funktion One are renowned for the controlled energy of our loudspeaker systems – this is nowhere more evident than in our bass enclosures which deliver physicality with accuracy for truly involving musical experiences. In the 1980s Funktion One’s Tony Andrews pioneered work on the development of the first 21” loudspeaker ever made. 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. More recently, with F1's access to advanced materials and Andrews’ heightened understanding of loudspeaker and enclosure tuning, his original 21” concept was due for a revisit. By using Neodymium instead of Ceramic, the magnet weight has been reduced from 28.5kg to 11.5kg which opened the possibility for a dual 21”. The Funktion-One designed drivers are incredibly robust and have 6” voice coils for maximising power input. The resulting F221 is an exceptionally efficient high-intensity bass enclosure providing fast, accurate, physical bass of the highest calibre.

The product is supplied with a choice of 4 Ohm or 8 Ohm drivers and optional wheels and throat grills.


Funktion One Resolution 1

Funktion One Resolution 1


The Resolution 1 is a radical 2-way loudspeaker enclosure resulting from Tony Andrews' 30 years pioneering research and development of high efficiency cone mid-range. This has resulted in a completely new 5 inch loudspeaker which eliminates the need for compression drivers with their inherent harshness and distortion. This device, when used in conjunction with a miniaturised, dedicated Axhead-loaded waveguide, smoothly reproduces both the vital mid range and high frequencies with exceptional coherency and detail. Further, instead of stretching the response of a compromised compression driver to (almost) meet an equally stretched and indistinct 12'' or 15'' low frequency driver at 1 to 2 kHz as in traditional 2-way systems, Funktion One's new 5'' device smoothly connects with the (outstanding) 12'' ported bass driver at 520Hz. The resulting bass is lively and very well defined.The high efficiency , projection and imaging of the R1 make it hard to imagine that it comes in such a compact and lightweight package.



Funktion One Resolution 1.5

Funktion One Resolution 1.5


The R1.5 builds on the success of the R1, we have created a 2-way enclosure with 90 degree dispersion, super high-fidelity and incredible low frequency output for its small size. It is perfect for applications needing a single enclosure per side including club, theatrical and live sound use. For the first time we have combined our unique 5'' cone loudspeaker with a new 90 degree axhead-loaded waveguide and substantial 18'' bass to offer an extremely capable two way enclosure.In common with the Resolution 1, the 5'' eliminates the need for compression drivers with their inherent harshness and distortion. The 5'' driver's ability to operate cleanly down to a low crossover point of 520 Hz allows the transition to the bass driver to be of exceptional smoothness.



Funktion One Resolution 2

Funktion One Resolution 2


This portable 'full-range' system is probably the smallest fully horn loaded enclosure available. Its unique combination of compact size, weight and sonic excellence, make it equally suited for use by discerning musicians as well as by sound consultants in demanding projects. From small to medium club venues to critical AV and pro sound reinforcement applications, this loudspeaker system resolves the requirement for quality, response and level from a small source. The Resolution 2 is increasingly acclaimed as the dj monitor of choice. If even more bass 'weight' is required, a pair of Resolution 2s can be used with additional Funktion One bass including Infrabass and F121s.The Resolution 2 is a full range, 3-way bi-amplified horn loaded enclosure with a passive high frequency crossover.
