Funktion-One Speakers for Sale | RES 4T & AX88 Professional Packages

The Funktion-One speakers for sale in this listing include two distinct professional loudspeaker packages: a sequentially numbered pair of Resolution 4T (RES 4T) speakers for €5,200 and a pair of AX88 speakers for €2,600. All speakers are stated to be perfectly working with their original components. The RES 4T package includes wheelboards, covers and external crossovers for bi-amp operation, while the AX88 pair comes with a flight case and hanging hardware. Buyers can therefore choose between two different Funktion-One configurations according to their professional sound-system requirements.

Rather than treating these as identical speaker packages, each pair has its own advantages. The RES 4T package focuses on Resolution Series performance and bi-amp flexibility, while the AX88 package combines a compact professional loudspeaker format with useful transport and installation accessories.

Two Funktion-One Speaker Packages Available

The available inventory is:

All four loudspeakers are stated to have original working components.

The two RES 4T cabinets also carry sequential serial numbers, which adds another useful detail for buyers specifically looking for a matched pair.

Funktion-One RES 4T Pair – €5,200

The first package consists of:

• 2 × Funktion-One RES 4T
• Sequential serial numbers
• Original components
• Perfectly working
• Wheelboards included
• Covers included
• External crossovers included
• Bi-amp operation capability
• €5,200 for the pair

This is the more comprehensive of the two packages, particularly for buyers who want a matching Resolution Series pair with transport accessories and the external crossover equipment already supplied.

Sequential RES 4T Serial Numbers

The two RES 4T cabinets have sequential numbers.

That can be an attractive detail when purchasing used professional loudspeakers as a pair because the units originate from the same closely matched production sequence.

For venues and professional system operators who want matching left and right cabinets, sequential numbering gives this pair an additional selling point beyond simply having two speakers of the same model.

Original Components and Perfect Working Condition

These Funktion-One speakers for sale are stated to retain their original components and to be perfectly working.

For established professional audio equipment, component originality can be important.

Loudspeakers can receive replacement drivers and other repairs during their working lives. Consequently, buyers often want to know whether the cabinets still retain their original internal equipment.

For this listing, originality and working condition should remain two of the most prominent product details.

External Crossovers for RES 4T Bi-Amp Mode

The RES 4T package also includes external crossovers for bi-amp operation.

Bi-amplification allows different sections of an appropriately configured loudspeaker system to use separate amplifier channels.

Therefore, the supplied crossover equipment is a meaningful part of this package rather than a minor accessory.

Professional buyers should still match the cabinets with suitable amplification and configure the system according to the appropriate Funktion-One requirements.

RES 4T Wheelboards Included

Wheelboards are supplied with the RES 4T pair.

This is especially useful for:

• Touring companies
• Rental businesses
• Mobile event systems
• Warehouse handling
• Venue production teams

Professional cabinets can be moved repeatedly throughout their working lives. Therefore, suitable wheelboards can make routine loading and positioning considerably more convenient.

Protective Covers Included

The RES 4T package also comes with covers.

Covers help protect the loudspeaker enclosures during storage and transportation, particularly against routine cosmetic wear.

Combined with the wheelboards, they make this package better prepared for professional transportation than a pair of bare cabinets.

For rental companies in particular, both accessories provide practical value.

Funktion-One AX88 Pair – €2,600

The second package provides a different approach.

For €2,600, the buyer receives:

• 2 × Funktion-One AX88
• Original components
• Perfectly working
• Flight case included
• Hanging hardware included
• €2,600 for the pair

This package may appeal more strongly to buyers looking for a professional Funktion-One solution with installation flexibility and dedicated transport protection.

AX88 Flight Case Included

A flight case is included with the AX88 pair.

For professional audio buyers, this can be valuable because the case provides a dedicated solution for storing and transporting the speakers.

Rental companies can move the pair between productions while keeping the cabinets better protected from routine handling.

Likewise, venues can use the case for safe storage whenever the speakers are not permanently deployed.

Hanging Hardware Included with the AX88 Pair

The AX88 speakers also come with hanging hardware.

That makes the package especially interesting for suitable installation applications where the cabinets need to be suspended rather than floor positioned.

However, any flown loudspeaker installation is safety-critical. The supplied hardware should therefore be inspected, correctly identified and used according to applicable manufacturer documentation and local regulations.

Professional rigging should always be carried out by appropriately qualified personnel.

Two Packages for Different Professional Applications

Although both pairs carry the Funktion-One name, they do not need to target exactly the same buyer.

The RES 4T package may be particularly attractive for:

• Resolution Series owners
• Touring PA companies
• Rental businesses
• Live music systems
• Professional club systems
• Buyers wanting bi-amp flexibility

Meanwhile, the AX88 pair can be particularly interesting for:

• Fixed installations
• Clubs and bars
• Fill applications
• Distributed systems
• Event spaces
• Venues requiring flexible mounting

This distinction helps make the product page more useful than simply presenting four speakers under one generic listing.

Funktion-One Speakers for Club and Venue Systems

Professional venues are an important market for these Funktion-One speakers for sale.

Funktion-One systems are widely associated with music-led entertainment environments, particularly where system design and sound quality receive serious attention.

However, loudspeaker performance depends on the complete system.

Amplification, processing, low-frequency reinforcement, speaker placement and room acoustics should all be considered when designing a professional installation.

Professional Amplification Required

Amplifiers are not listed as included with either package.

Therefore, buyers should plan for appropriate professional amplification.

For the RES 4T package, this becomes particularly important because the supplied external crossovers support its bi-amp configuration.

Before operation, professional users should confirm:

• Amplifier requirements
• Loudspeaker impedance
• Crossover configuration
• Limiter settings
• Gain structure
• Polarity
• Cable configuration
• Correct system processing

These details should be configured according to the intended system rather than estimated from amplifier wattage alone.

Useful for Existing Funktion-One System Owners

These packages may be especially valuable for businesses already operating Funktion-One equipment.

Existing owners may already have compatible:

• Amplifiers
• System processors
• Bass enclosures
• Cabling
• Rigging equipment
• Technical staff familiar with Funktion-One systems

Consequently, adding another RES 4T or AX88 pair may be more practical than introducing a completely different loudspeaker platform.

Which Funktion-One Package Should You Choose?

The better option depends on the intended application.

Choose the RES 4T pair at €5,200 if your priority is a matched sequential Resolution Series pair with wheelboards, covers and external crossovers for bi-amp operation.

Choose the AX88 pair at €2,600 if you need a different professional Funktion-One format supplied with a flight case and hanging hardware.

For some professional operators, both packages may also complement different parts of a larger sound inventory.
