Funktion One are English inventors and manufacturers of professional loudspeaker systems. Achieving the best possible audio quality is the principle motivating factor at Funktion One. Intent on sonic accuracy, their technological approach avoids the use of both system use of both system EQ (with its inherent phase and headroom problems) and compression driver mid-range (with its inherent harshness and distortion). Their loudspeaker systems also have excellent directional control allowing sound to be focused where it’s needed and minimising out-of-venue environmental impact. Their designs also focus on maximising efficiency (conversion of amplifier power into acoustic energy) as this tends to produce alive and responsive sound. It also means that less electrical power is required for a given acoustic output making F1 Resolution systems more energy efficient compared to alternatives.
