Estimated Retail Value and Resale Margin

Sequential serial numbers on a matched pair of Funktion-One loudspeakers in perfect ex-install condition is an uncommon combination on the secondary market. Most used Funktion-One units available for sale come from touring or rental environments with corresponding cosmetic wear. These units have spent their life in a fixed installation, which is the lowest-stress operational environment for a loudspeaker cabinet.

Real Profit Example for AV Resellers and Rental Companies

A rental company purchasing one pair at €4,000 and deploying the pair at boutique events, club residencies, or hospitality installations at €200 to €350 per event day would recover the purchase cost in 12 to 20 event days. A reseller purchasing both pairs and listing them individually on the secondary market at current secondary market prices for perfect-condition Funktion-One Resolution 2 units would find strong buyer demand, particularly in Europe where the Funktion-One brand commands a premium among nightclub operators and high-end venue owners.

These figures are illustrative. Actual returns depend on your market, pricing, and deployment frequency.

What Is the Funktion-One RES 2U MK2

The Funktion-One Resolution 2 is an entirely horn-loaded, surprisingly compact, full range loudspeaker enclosure. The driver complement comprises a 15-inch driver for bass, an 8-inch for midrange, and a 1-inch for high frequencies. Funktion-One’s waveguide and driver technology produces clear, involving and powerful sound. The RES 2’s unique combination of size, high efficiency and sonic excellence make it ideally suited to a wide range of uses.

The RES 2U is the horizontal version of the Resolution 2, available for installation in venues with low ceiling heights. The MK2 designation indicates the second generation of the cabinet, which includes updated driver and crossover specifications relative to the original. The Resolution 2 features a full range standalone enclosure, fully horn loaded for high efficiency, three-way bi-amplified configuration with passive HF, Funktion-One designed drivers, a complete range of flying and mounting options, and M10 fly points.

The RES 2U MK2 in this listing supports both horizontal and vertical orientation, which gives installation engineers and rental operators deployment flexibility that standard single-orientation cabinets do not provide.

What Is a PA System and Where Does the RES 2U MK2 Fit

A PA system is the complete audio reproduction chain that delivers amplified sound to an audience at the required coverage and output level. In professional club, venue, and event sound, the full-range loudspeaker is the most critical component for audience experience. It defines the tonal character, clarity, and projection of everything the audience hears.

Funktion-One occupies a specific and well-defined position in this market. Their loudspeakers are chosen by venue owners, club operators, and event designers for whom audio quality is a non-negotiable requirement rather than a variable. The RES 2U MK2 is suited for nightclubs, boutique venues, corporate event installations, high-end hospitality sound systems, and rental inventories targeting clients who specify Funktion-One by name.

For PA system design guidance and amplifier pairing references for the RES 2U MK2, sasphonik.com and Boston Pro Sounds are practical resources used by professionals building systems at this level.
