You know DO 44: High-performance acoustic speakers for indoor and outdoor events

The DO speaker 44 Joins Vieta's DO Line line of passive acoustic enclosures to provide high projection of music and voice in both closed and open environments.

Vita Pro, whose products it distributes in Spain and Portugal Commercial Acson, has incorporated DO Line into its line of high-performance passive acoustic enclosures, the DO model 44, Designed with acoustic features that make them ideal for use in both outdoor and indoor settings..

The rotating logo of the DO 44 allows its use both horizontally and vertically and the membrane design implemented in its four loudspeakers 4 inches offers a linear response between 90 Hz – 17 Khz.

Its assembly in MLC form (Multiunit Lineal Clusters) provides high projection of music and voice. This system allows increasing horizontal coverage to 100º, beyond the frequency of 5 Khz, as well as the acoustic pressure, and reduce the compression factor that occurs in the speakers.

The aluminum grille, stainless steel hardware, An ABS enclosure treated against UV rays and tropicalized speakers guarantee its use outdoors. The LT-54 toroidal transformer (optional) allows its use in 70-100V lines, respecting the frequency response between 40 Hz – 18 Khz with just 1,5 dB drop in 18 Khz.

The transformer core has been sized for greater performance at low frequencies at maximum power, thus avoiding distortions at low frequencies that occur due to core saturation.

The DO Line is made up of ten high-performance passive acoustic enclosures that have been specifically designed to meet the multiple sound requirements imposed by the diversity of existing spaces.. Vieta recommends VDC-48 processors in order to optimize their frequency and dynamic response., controlling the maximum power applied to the system.
