Turbosound TQ15 

The TQ15 is a processed passive 2,200-watt 15″ loudspeaker system for speech and music reinforcement applications.

This 2-way full range speaker is engineered for use with Lab Gruppen-powered loudspeaker management systems.

It delivers strong performance for FOH, sidefill and delay line loudspeakers in demanding setups.

The enclosure features a 15″ neodymium low-frequency driver with a low mass voice coil for improved transient response.

It also uses a titanium dome 1.4″ neodymium high-frequency compression driver.

The driver is mounted on an 80° horizontal by 30° vertical rotatable exponential horn.

That horn is paired with a dendritic plane wave transformer (DPWT) waveguide.

All drivers are matched with an internal passive crossover network in a reflex-loaded enclosure.

The rear connector plate carries 2 x Neutrik speakON * NL4 connectors for input and link connections.

This neodymium speaker is finished in a highly durable semi-matt black paint.

The cabinet is constructed from 15 mm (5/8″) plywood and includes a powder-coated cloth-wrapped perforated steel mesh grille.

Multiple threaded rigging points allow suspension in any orientation, or mounting where required.

Optional flying yoke, and swivel brackets, are each available separately.

The cabinet also features a dual 35 mm socket for standard pole mounting and an integrated handle for transport.

Custom-Engineered Drivers, Waveguides and Horns

Turbosound is recognised worldwide for designing iconic loudspeakers and subwoofers.

This turbosound professional loudspeaker uses drivers, waveguides, and horns designed to exact standards.

The refined curved exit dendritic is matched with a new 80° x 30° rotatable horn.

That design supports accurate dispersion through the bandwidth of the high-frequency device.

Integration with Lab Gruppen PLM+ for TQ15

With the complexity of modern-day sound systems, seamless integration with Lab Gruppen PLM+ is essential.

Engineers have prepared presets to help achieve maximum system performance and consistency.

These can be found in the download section.

Future FIR-capable platforms from Lab Gruppen will also be supported.

Acoustic Simulation Tools

EASE GLL files are provided for the EASE Focus 3 Acoustics Simulation Software.

This free download allows accurate calculation of acoustic coverage and suspension pick point selection.

It also helps with tilting and aiming the cabinet at the desired angle.
