d&b Audiotechnik Q1 for Sale | Professional 2-Way Line Array Loudspeaker

The d&b Audiotechnik Q1 for sale is a compact passive line-array loudspeaker developed for professional vertical-array applications. With two 10-inch low-frequency drivers, a 1.3-inch high-frequency compression driver and 75° horizontal constant directivity, the Q1 combines substantial output with a cabinet weighing approximately 22 kg. For touring companies, rental businesses and venues maintaining d&b Q-Series inventory, it remains a practical option for expanding or completing an established professional PA system.

Unlike a conventional point-source cabinet, the Q1 was designed specifically to work with multiple matching enclosures. Adjustable splay angles allow engineers to shape an array according to the audience area, while compatible d&b amplification provides dedicated Q1 processing, protection and system modes.

What Makes the d&b Q1 Different?

The Q1 uses a two-way passive acoustic design built around three primary components:

• 2 × 10″ low-frequency drivers
• 1 × 1.3″ high-frequency compression driver
• Toroidal high-frequency waveguide

The two 10-inch drivers operate in a dipole arrangement. Meanwhile, the HF section provides the controlled vertical behavior needed when several Q1 cabinets combine into an array.

This configuration allows a relatively compact enclosure to become part of much larger systems without requiring every cabinet to operate as an independent point source.

d&b Q1 Technical Specifications

*Maximum SPL depends on amplifier platform, loudspeaker configuration and applicable measurement conditions.

75° Horizontal Constant Directivity

Coverage control is one of the defining characteristics of the Q1.

The cabinet provides 75° nominal horizontal dispersion, which remains controlled through a significant portion of its operating range.

For professional system designers, this makes it possible to predict how multiple Q1 cabinets will distribute sound across an audience.

Furthermore, the controlled horizontal pattern can help reduce unnecessary acoustic energy outside the intended coverage area.

15° Vertical Coverage Per Cabinet

Each Q1 provides approximately 15° of vertical dispersion in the high-frequency range.

However, the real advantage appears when multiple cabinets are combined.

The integrated rigging allows splay angles from approximately 0° to 14° between cabinets. Therefore, engineers can create flatter sections for longer projection or progressively increase angles to cover audience areas closer to the array.

This flexibility is fundamental to the Q1’s intended use as an array element.

Build a Q1 Array Around the Venue

A Q1 system does not need to use the same array configuration for every event.

Depending on the venue, coverage requirements and approved rigging configuration, multiple cabinets can form arrays with different vertical profiles.

Smaller configurations may suit venues with modest audience areas, while larger arrays can provide greater vertical coverage and output for more demanding productions.

The supplied system information indicates configurations of up to 20 Q1 cabinets in suitable flown arrays.

Final array design, however, should always follow the applicable d&b documentation and professional system-prediction procedures.

Standard and CUT Operating Modes

Compatible d&b amplification provides dedicated processing modes for the Q1.

In standard operation, the supplied frequency range is approximately:

60 Hz – 17 kHz

When the system operates with dedicated subwoofers, CUT mode reduces the Q1’s low-frequency output. The resulting stated response begins at approximately:

100 Hz – 17 kHz

Therefore, the main cabinets do not need to reproduce as much low-frequency energy when suitable subwoofers handle that part of the spectrum.

Pair the Q1 with Q-SUB

One particularly natural system combination is Q1 with Q-SUB.

The Q-SUB uses an 18-inch low-frequency driver and was developed as part of the same Q-Series ecosystem. Consequently, it can provide dedicated low-frequency reinforcement while the Q1 array handles the main audience coverage.

For rental businesses maintaining complete Q-Series systems, this matching architecture can simplify equipment planning compared with combining unrelated loudspeaker platforms.

Other compatible subwoofer configurations may also be possible depending on the applicable d&b system design.

HFC for Longer Throw Applications

The Q1 also supports High Frequency Compensation (HFC) through compatible d&b amplifier configurations.

High frequencies lose more energy through air absorption as distance increases. Therefore, cabinets covering more distant audience areas may require different compensation from those addressing listeners closer to the array.

HFC provides a manufacturer-designed approach for managing this effect within supported Q1 systems.

This can be particularly valuable in larger venues and outdoor productions.

CPL for Array Coupling Control

Another available function is CPL, or Coupling.

When several loudspeakers operate together, acoustic interaction changes compared with a single cabinet.

CPL processing can help adjust this behavior within supported d&b system configurations.

As a result, technicians have additional control when tuning longer Q1 arrays for different venues and deployment sizes.

d&b Audiotechnik Q1 for Sale for Existing Q-Series Owners

For a professional business already using Q-Series equipment, finding a d&b Audiotechnik Q1 for sale can be particularly useful.

Additional matching cabinets may allow you to:

• Increase the size of existing arrays
• Build additional left/right configurations
• Maintain spare Q1 cabinets
• Replace missing inventory
• Expand a rental package
• Complete an existing Q-Series system
• Maintain consistency across installed systems

Moreover, existing Q-Series users may already own compatible amplifiers, Q-SUBs, cables and rigging equipment.

High Output from a 22 kg Cabinet

The Q1 weighs approximately 22 kg, making it relatively compact for a professional line-array element of its generation.

The supplied specifications state maximum output of up to approximately 139 dB, depending on the compatible amplifier and operating conditions.

However, maximum SPL should not be considered in isolation.

The real performance of a Q1 system depends on cabinet quantity, array geometry, amplification, processing, venue acoustics and system tuning.

Professional Touring Construction

The Q1 enclosure uses robust plywood construction with a durable protective finish.

A rigid metal grille protects the drivers, while acoustically transparent foam sits behind the grille.

Integrated side handles assist with transportation and positioning.

Meanwhile, dedicated front and rear rigging components allow cabinets to connect into appropriate array configurations.

Compact Cabinet Dimensions

The approximate dimensions are:

Height: 308 mm
Width: 580 mm
Depth: 410 mm
Weight: approximately 22 kg

The relatively compact enclosure can benefit rental businesses that need to transport larger quantities of cabinets.

Rigging Designed Around the Q-Series

The Q1 incorporates purpose-designed array hardware rather than relying on generic mounting solutions.

This allows cabinets to connect mechanically while the appropriate splay angle determines their relationship within the array.

Because suspended loudspeaker systems involve significant loads, rigging hardware should always be inspected before deployment.

Furthermore, array size, working-load limits and suspension methods must follow the applicable manufacturer documentation and local safety requirements.

Compatible d&b Amplification

Q1 requires an appropriate d&b amplifier configuration for correct operation.

Over its service life, the Q1 has been supported by different generations of d&b amplification. Therefore, buyers should verify compatibility with the specific amplifier they intend to use.

The correct amplifier setup provides not only power but also the required loudspeaker processing and protection.

For professional applications, this is considerably more important than selecting an amplifier based only on its wattage rating.

NL4 and EP5 Versions

Depending on production version, Q1 cabinets may have different connector configurations.

The supplied information includes NL4 connectivity, while some system inventories may include EP5 configurations.

Consequently, customers adding Q1 cabinets to an existing system should verify the connector type before purchase.

Doing so helps ensure compatibility with existing amplifier racks and cable inventories.

Ideal Environments for Q1

Although the Q1 belongs to an earlier generation of d&b equipment, its professional array architecture makes it relevant to several applications where compatible systems remain in service.

Typical environments include:

• Concert touring
• Music festivals
• Professional PA rental
• Theatre productions
• Corporate events
• Performance venues
• Fixed professional installations
• Live music systems
• Q-Series inventory expansion

The strongest use case is generally for businesses already invested in the d&b Q-Series ecosystem.

Previous-Generation Professional Equipment

Q1 is no longer d&b’s newest line-array technology.

Therefore, buyers should approach used Q1 inventory differently from a current-production loudspeaker.

Cabinet condition, driver originality, rigging condition, connector version and service history are all important considerations.

At the same time, previous-generation equipment can remain commercially useful when a company already owns the surrounding system infrastructure.
