DVA T4
High Efficiency
The 6.5“ Neodymium-Midrange speaker has a sealed basket to provide an optimized
volume capacity including high sensitivity and superb sound reproduction. It also
has a horn exit including phase plug for defined and linear sound emission.

Constant Directivity
The DVA T4 Top is equipped with a constant directivity horn for the High and Mid
section and offers a nominal coverage angle of 100°x15°. The CD-Horn provides
high flexibility and a good natured attitude if for instance the Array is not aligned
correctly.
The DVA uses apart from the formation of cylindrical waves (very much depending
on the number of T4 elements) the vector summing of the individual horns. This
means that with growing distance to the source (if set up correctly) the listener
perceives more and more vector sums of the single elements.
However it has to be considered, that the fewer elements are used to spread the
sound to a specific area, the stronger must be the curving of them. That’s how the
effect of optimised SPL distribution is managed.
State-of-the-Art Drivers
The build in 1”Neodymium- Drivers are equipped with a 1.4” Mylar- Membrane
which allow a very quick response and provide a linear frequency range at a
surprisingly low weight. This driver was specially designed for the use with Line-
Arrays. Its compact measurements allow very close proximity which is a main factor
for minimum interference.
