Another important and unique feature of Funktion One products is the use of paper cone drivers right across the vocal range up to around 6KHZ. This results in vocal range without crossover points. There is no use at all of harsh metallic 2" compression drivers in any of our products. Instead we are able to use 1" compression drivers crossed over above 6KHZ which at this frequency have more top end than 2" drivers anyway. Nearly all other systems use 2" compression drivers from as low as 650 HZ to 1K6 to reproduce the vocal range but this has a number of problems:-
1. The sound path through the typical phase plug is very torturous and introduces a great deal of distortion.
2. Dynamically and therefore perceptually 2" drivers have a very strong peak between 2KHZ and 3.5KHZ which is very aggravating as this is in the speech recognition frequency band to which the human ear is most sensitive. The end result is further exacerbated by the masking of the lower voice frequencies removing the richness and warmth of the human voice.
3. The reliance on delicate compression driver diaphragms for this frequency range renders the system vulnerable to unreliability as voice coils are easily burnt and diaphragms are prone to shatter. Paper cone drivers are far more robust but require specialised knowledge to employ successfully.
The sum result of all these considerations in Funktion One products is an unmatched smoothness across the entire frequency range without any loss of efficiency and much improved accuracy and intelligibility. Our efficiency stems from the use of Funktion One's specialised patented Axhead horn loading techniques that overcome the usual resonant peaks and uncontrolled high frequency problems of normal horns. Highly efficient loudspeakers mean fewer loudspeakers are needed giving improved economy and there is less stress on the rest of the electronic components in the whole sound system with consequent improvement in dynamic range. All these sonic improvements have been achieved whilst simultaneously reducing the size and weight of our enclosures. In fact I believe that our products are the smallest and lightest in the world.
