Turbosound TFM-420 Monitor System for Sale | 8 Speakers + Lab Gruppen Amp Rack | €4,000

The Turbosound TFM-420 system for sale is a complete professional stage-monitor package featuring 8 × Turbosound TFM-420 bi-amped floor monitors, supplied in flightcases, together with a dedicated amplifier rack containing 2 × Lab Gruppen FP2400Q amplifiers and 1 × dbx DriveRack processor. The complete package is offered for €4,000.

The TFM-420 was designed as Turbosound’s high-performance bi-amped professional floor monitor, using neodymium components, a 12″ low-frequency driver and high-frequency compression driver in a compact touring enclosure.

Complete Turbosound TFM-420 Package

This is particularly attractive for professional buyers because the sale combines the monitor wedges, transportation cases, amplification and loudspeaker processing within one package.

8 × Turbosound TFM-420 Professional Stage Monitors

The package contains:

8 Turbosound TFM-420

The TFM-420 is a professional bi-amped two-way floor monitor developed for demanding stage-monitoring applications.

Each cabinet uses a custom 12″ neodymium LF driver alongside a high-power neodymium HF compression driver. Turbosound designed the drivers side-by-side on an angled baffle, producing a relatively low-profile monitor enclosure while maintaining high output and controlled coverage.

TFM-420 Technical Specifications

These figures come from Turbosound’s TFM-420 engineering documentation.

Professional Bi-Amp Operation

An important feature of the TFM-420 is its:

Active bi-amped configuration

Rather than relying on a simple internal passive crossover, the LF and HF sections are driven separately with appropriate external processing and amplification.

Turbosound specified an active crossover point around 1.3 kHz with a 24 dB/octave Linkwitz-Riley slope for the TFM-420.

That architecture makes the included amplifier rack and DriveRack particularly useful as part of this package.

High-Output Stage Monitoring

The TFM-420 was designed for situations where performers require strong monitor output while maintaining intelligibility.

Published output reaches approximately:

130 dB continuous

and

136 dB peak

per cabinet under the manufacturer’s stated test conditions.

Typical applications include:

• Vocal monitoring
• Live bands
• Concert stages
• Festival monitoring
• Drum fills
• Professional touring
• Theatre productions
• Front-of-house applications

40° × 60° Controlled Coverage

Each monitor provides approximately:

40° horizontal × 60° vertical dispersion

The enclosure was also designed symmetrically so that multiple TFM-420 monitors can be arranged as mirror-image left/right pairs.

This is particularly useful on professional stages where several performers require separate monitor positions.

Flightcases Included

All 8 Turbosound TFM-420 monitors are supplied with flightcases.

For touring and rental companies, this adds significant practical value because the monitors can be transported and stored with additional protection.

Flightcases are particularly useful for equipment that is regularly moved between:

Warehouses → Trucks → Venues → Stages

and back again.

2 × Lab Gruppen FP2400Q Amplifiers

The amplifier rack contains:

2 Lab Gruppen FP2400Q

The FP2400Q is a professional four-channel power amplifier, giving the two included units a total of:

8 amplifier channels

The FP2400Q uses a compact 2U chassis and was designed for professional multi-channel sound reinforcement. Published specifications vary according to load and MLS configuration, so amplifier settings should be matched carefully to the TFM-420 system configuration.

dbx DriveRack Processor Included

The rack also contains:

1 × dbx DriveRack

This provides loudspeaker-management functionality for configuring the monitor system.

Depending on the exact DriveRack model installed in the rack, processing can include functions such as:

• Crossover management
• Equalization
• Output limiting
• Delay
• Routing
• Loudspeaker protection

The exact DriveRack model should be shown in the product photographs or final inventory because different DriveRack generations have different input/output and processing capabilities.

Complete Touring Monitor Package

The combination of eight monitors and a dedicated rack makes this much more than a collection of individual speakers.

The buyer receives:

8 × Turbosound TFM-420

Flightcases

2 × Lab Gruppen FP2400Q

1 × dbx DriveRack

Amplifier rack

for:

€4,000 Complete

That works out to an attractive package price when considering the loudspeakers, cases, amplification and processing together.

Ideal for Professional Touring

The TFM-420 was specifically designed around demanding professional monitoring requirements.

Turbosound used neodymium components to keep each cabinet’s published weight to approximately 25.2 kg, while the low-profile wedge design helps preserve stage sightlines.

For touring companies, the supplied flightcases make the complete eight-monitor package considerably easier to transport and protect.

Suitable for PA Rental Companies

A set of eight matching monitors can be especially useful for rental inventory.

Rather than mixing different monitor models across a stage, a rental company can deploy matching TFM-420 cabinets for multiple performers.

The package can be considered for:

Concerts

Festivals

Touring productions

Live bands

Corporate events

Theatres

and other professional productions.

That makes it particularly relevant for a touring company, venue or professional rental provider looking for a ready-to-integrate monitor inventory.
