Pulz Quartet QM1 is an advanced true Line Source System capable of high SPL and linear frequency response.
Quartet QM1 is designed for easy powering, convenience in deployment and to deliver outstanding sound quality in large cinemas. The system is powered with two high performance 8” Low-Mid drivers, the best in its class in conjunction with a 1.75” voice coil compression driver of superior sonic quality.
A specially designed waveguide loads the HF driver to create a true line source with minimum internal diffraction and associated distortions.
The LF section is loaded both in front and rear for optimum coupling and extended LF response. A minimum loss passive crossover integrates the HF and LF sections further assisted by external advanced digital processing to achieve flat frequency response.
Quartet QM1 is built using 15 mm Marine Grade Birch Plywood finished with abrasion resistant polyurethane paint. The speakers can be ground, stacked or flown with optional rigging accessories. Each box can be tilted individually from 0.5° to 12° with fine increments to achieve desired vertical coverage. Speakon connection on the back plate ensures secure speaker connections. Upto four Quartet QM1 boxes can be powered by a single channel of a high power amplifier, making the system easy to wire and deploy efficiently.
The Quartet QM1 is designed taking into consideration all the practical aspects of line source deployment yet not compromising on the ultimate sonic quality and long term consistent reliable performance.
