The F121 provides outstanding bass performance from a moderately sized enclosure making it the bass of choice for many diverse applications. Similar in output power to an F218, this single 21” version of the F221 can be used with virtually all Funktion One mid-high loudspeakers to great effect. The advanced loading and driver design of this high-efficiency product provides audiences and crowds around the world with stimulating and satisfying experiences. The F121 comprises a horn-loaded and very robust Funktion One designed 21” driver with 6” voicecoil and Neodymium magnet. Available in 4 Ohm or 8 Ohm versions with optional wheels, throat grill and pole mount.

The F218 Mk2 is the latest iteration of Funktion One’s long established and highly respected dual 18” bass enclosure. This is the result of a holistic approach over many years of research and development into bass loading techniques. The evolved product is highly regarded for its extreme robustness and delivery of tight, punchy, well defined clean bass from a relatively small and very manageable package. It has often been emulated but never equalled. The F218 brings refined loading, improved heat dissipation and an updated driver specification.

The Resolution 5 Touring enclosure is a high intensity three-way, mid-high loudspeaker used to create accurate point-source arrays. The unique and patented midrange Axhead loading device not only gives incredible efficiency and dispersion control, but also increases high frequency output from the 8" cone driver. This means that the crossover point to the compression driver can be raised to around 6kHz for dramatically reduced distortion compared to the compression driver based midrange so prevalent in the industry. Its highly controlled and focused dispersion enables precise tailoring of overall system coverage, simply through the geometry of the array. Unwanted room reflections are thereby substantially reduced, maintaining the enclosure's high intelligibility. The system's flexibility in application makes it suitable for any event size from 500 people to the largest festival, thereby maximising use of rental inventory. Its innovative and simple integrated flying system, combined with minimal size and weight, allow for easy and effective flying or ground stacking. The Resolution 5 is economic in terms of system cost, production budget and truck space. Above all, the accuracy and sonic quality it delivers are exceptional for all genres of music.

The Resolution 2 is an entirely horn-loaded, surprisingly compact, full range loudspeaker enclosure. The driver complement comprises a 15” for bass, an 8” for midrange and a 1” for high frequencies. Funktion One’s waveguide and driver technology produces clear, involving and powerful sound. The R2’s unique combination of size, high efficiency and sonic excellence make it ideally suited to a wide range of uses. This loudspeaker resolves the requirement for quality, response and level from a small source. Resolution 2 systems can be supplemented with additional Funktion One bass including Infrabass, BR Series or F Series enclosures. A slightly larger horizontal version (R2U) is available for installation in venues with low ceiling heights.

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. The Funktion-One designed drivers are incredibly robust and have 6” voice coils for maximising power input. The powerful Neodymium magnet provides very high magnetic flux density whilst significantly reducing the weight compared to ceramic. The resulting F221 is an exceptionally efficient high-intensity bass enclosure providing fast, accurate, physical bass of the highest calibre.

The F88 comprises two Funktion One designed wide bandwidth 8” loudspeakers with a passive slot tweeter delivering frequencies above 6kHz. Particular attention has been paid to the arrangement of the drive units to optimise coherency. The F88’s 110° dispersion and 99dB sensitivity from 70Hz to 18kHz allow it to be used in numerous applications including under-balcony, theatre, bar/club, cinema surround and AV. The F88 delivers full-range sound in its own right and can be given more authority with the addition of Funktion-One bass enclosures including MB212 and F or BR118.

Extend your low-end with this portable powerhouse. Whether used on its own or with a sub, the ZLX-15P provides crisp, clean highs and tight, deep lows for larger spaces – all with enough amplifier headroom to make sure you’re heard both loudly and clearly.

The R2SH skeletal loudspeaker is the mid-high section of a Resolution 2 producing high output for its compact size. Operating upwards from 250Hz it can either be used in conjunction with Funktion One bass enclosures such as the F118, F215 or BR118 as a main system in its own right, or used effectively as in-fill or delays in larger systems.

The Resolution 1 is a radical, 2-way loudspeaker enclosure, resulting from Tony Andrews’ 40 years pioneering research and development of high efficiency cone mid-range. A unique Funktion-One 5” loudspeaker eliminates the need for compression drivers with their associated harshness and distortion. This device, when used in conjunction with the dedicated Axhead-loaded waveguide, smoothly reproduces both mid-range and high frequencies with exceptional coherency and detail. Further, this 5" device seamlessly connects with the 12" ported low frequency driver at 520Hz. This is in contrast to conventional 2-way systems where compromised compression drivers are stretched to (almost) meet equally stretched and indistinct 12" or 15" low frequency drivers at between 1 and 2kHz. The accuracy, projection and imaging detail of the R1 make it ideally suited to high intelligibility applications including theatrical use.
