About the Funktion One Resolution 4D Downfill
The Funktion One Resolution 4D Downfill is a two-way active horn-loaded enclosure purpose-built to complete Resolution 5 flown arrays. Its unique tapered shape allows cabinets to be coupled closely together, generating a coherent wave-front, while the 50-degree vertical dispersion provides coverage right down to the first row of seats. Funktion One designed neodymium drivers contribute to high efficiency, and the nominal dispersion measures 25 degrees horizontal by 50 degrees vertical across a frequency response of 445Hz to 18kHz. Connections are handled via an EP6 panel and captive lead, and all inter-cabinet flying hardware is included as standard. The enclosure weighs 20kg and an optional scrim is available for a more discrete appearance.
Funktion One Resolution 4D Downfill — buyer FAQs
What is the Funktion One Resolution 4D Downfill and what role does it play in a flown array?
The Funktion One Resolution 4D Downfill is a two-way, active, horn-loaded enclosure built specifically to complete Resolution 5 flown arrays. Its 50-degree vertical dispersion extends coverage down to the first row of seats, and its unique tapered shape allows cabinets to be coupled closely together to generate a coherent wave-front while maintaining the spherical cluster's overall form.
What are the key specifications of the Resolution 4D Downfill?
The Resolution 4D Downfill covers a frequency response of 445Hz to 18kHz (plus or minus 3dB) with a nominal dispersion of 25 degrees horizontal by 50 degrees vertical. It connects via an EP6 panel and a captive lead in the cable recess, weighs 20kg (44lbs), and uses Funktion One designed neodymium drivers for high efficiency. All inter-cabinet flying hardware is included as standard.
Who makes the Resolution 4D Downfill and where does it sit in the Funktion One range?
The Resolution 4D Downfill is made by Funktion One, a British loudspeaker manufacturer founded in 1992 and based in Dorking, Surrey. Within the range it sits as a dedicated downfill component for the Resolution 5 touring system, sharing the same design philosophy of horn loading and high efficiency that runs through Funktion One's professional touring enclosures.
What should I check when buying a used second-hand Resolution 4D Downfill?
Confirm that the built-in flying hardware is intact and undamaged, as the enclosure is designed for flown use with the Resolution 5 system. Check the EP6 connector and captive lead for wear, inspect the horn and drivers for physical damage, and verify the enclosure's weight and tapered shell are undistorted.
