PQ15

PQ15

The 2-way, full range PQ15 is a processed passive 2,000-Watt 15" loudspeaker system ideally suited for a wide range of speech and music sound reinforcement applications. Engineered to work in conjunction with Lab Gruppen powered loudspeaker management systems, the PQ15 provides optimal performance for FOH, side-fill, stage monitor and delay line applications.

The PQ15 features a 15" ferrite low frequency driver with a low mass voice coil for improved transient response, and a polyimide dome 1" neodymium high frequency compression driver mounted onto an 80° horizontal by 50° vertical rotatable exponential Catenary horn. All drivers are matched with an internal passive crossover network in a reflex-loaded enclosure. The rear panel connector plate carries 2 industry-standard twist-locking speaker connectors for input and link connections to additional enclosures.

Finished in a highly durable PU semi-matt black paint, the cabinet is constructed from 15 mm (5/8") plywood – and includes a rugged powder coated cloth wrapped perforated steel mesh grille. Multiple threaded rigging points are provided for suspension in any orientation, or for mounting. Optional flying yoke, swivel brackets, each available separately. The PQ15 also features a dual 35 mm socket for standard pole mounting – plus an integrated handle for convenient transport.

Custom-Engineered Drivers, Waveguides and Horns

Turbosound is recognised the world over for designing and building some of the most iconic loudspeakers and subwoofers. We take meticulous care and pride in maintaining that reputation by utilising only drivers, waveguides and horns designed and specified by ourselves to our exacting standards. Our new Catenary horn design gives an 80° x 50° dispersion for the bandwidth of the high frequency device.

Integration with Lab Gruppen IPX 4800 and PLM+

With the ever-increasing complexity of modern-day sound systems. Seamless integration with the Lab Gruppen IPX 4800 and PLM+ is a prerequisite for the PQ series from Turbosound. Our engineers have prepared and meticulously designed a series of presets that will allow the user to achieve the maximum system performance and consistency possible. These can be found within the download section. Future FIR capable platforms from Lab Gruppen will be supported.

Acoustic Simulation Tools

EASE GLL files are provided for the EASE Focus 3 Acoustics Simulation Software, which is available for free download. This allows accurate calculation of both acoustic coverage and selection of suspension pick point for tilting and aiming the cabinet at the desired angle.

Architecture and Engineering Specifications
