DOPPIA II 9075

Doppia II 9075 is a professional full range 3-way loudspeaker system, in version “A” for tri-amping or version “P” for bi-amping with passive low-loss crossover built in for the mid/high frequency section. It comprises a low frequency section using two 12” loudspeakers in hybrid reflex/band-pass configuration, a mid section with a high efficiency 10” loudspeaker loaded by a symmetric wave guide with a square mouth and low compression ratio and low distortion and a high frequency section using a compression driver with a 2” throat and 3” titanium diaphragm with overload protection, loaded by an asymmetric controlled directivity horn which also has a square mouth and can be turned through 90° on its axis inside the cabinet in order to change the horizontal/vertical dispersion. The acoustic reproduced bandwidth is 60.5 Hz – 19.7 kHz at -10 dB, with a great linearity of within ±3 dB from 77 Hz to 18.9 kHz, for the reproduction of many types of applications.

When tri-amplified, the system has high sensitivity for the low section 102 dB SPL at 1 m, 107 dB SPL at 1 m for the mid section and over 109 dB SPL at 1 m for the HF section. Driven at maximum peak power, each section is able to produce a maximum peak of 138 dB SPL (low), 142 dB SPL (mid) and 141 dB SPL (high) at 1 m. The overall short-term peak SPL is 145.5 dB SPL.

The maximum allowed power for each section is 400 Watt AES (1,600 peak) for basses, 300 Watt AES (1,200 peak) for midrange and 150 Watt AES (600 peak) for high. Average dispersion from 500 Hz to 4 kHz is 100° horizontal and 100° vertical, from 500 Hz to 10,000 Hz is 100° horizontal and 90° vertical for short and medium throw applications. The trapezoidal cabinet is built in high quality 15 mm baltic plywood, strengthened by the complex internal structure and suitably positioned internal bracing to eliminate any resonance of the cabinet’s sides. The black outer finish is in high quality scratch-resistant paint. The cabinet has 6 fast flying points, that makes vertical or horizontal hanging extremely easy and reliable, by using the appropriate optional accessories. The front of the enclosure has recessed sockets for fitting an optional trolley, for handling and protecting the fibreglass wave guides during transport. Six recessed integrated handles in the side panels of the cabinet are used for a positive grip during handling.
