THE STLA’S COENTRANT DRIVER
The patented CoEntrant Driver integrates the output of a cone transducer and a compression driver into a single
high output, wideband point source. Coupling these devices with Complex Conic horns has generated a number of
highly effective horizontal array modules – the ST Series of products.
The new CDT 1.5 CoEntrant driver has been developed for use in high output line array modules. It integrates a
6.5 inch carbon fiber cone transducer with a 2.5 inch voice coil compression driver. The CDT1.5 can be crossed
over as low as 350 Hz, allowing a properly designed waveguide to control dispersion over a frequency range of
almost six octaves.
CDT (COENTRANT DRIVER TECHNOLOGY) & PWGT: (PLANE WAVE GENERATOR
TECHNOLOGY): AN IDEAL COMBINATION
Because of its ability to function as a diffraction slot array at lower frequencies and as a path length refractor at
higher frequencies, the Plane Wave Generator is able to control vertical dispersion over the entire operating
bandwidth of the CDT1.5. A vertical array of these devices will produce a coherent wavefront from 350 Hz to
19 kHz. The sound system design can shape the vertical dispersion of this wavefront by altering the splay angle
between modules. This is the key to adapting the line array’s output to a particular venue in order to deliver
consistent SPL from front to rear.

Tie Bars and Quick-Release Pins are included with each Renkus-Heinz Line Array module. They provide simple
selection of inter-module splay angles within a metal-to-metal load bearing system that is independent of the
enclosure structure.
Please devote your time and attention to reading this manual. A comprehensive understanding of line array theory,
curved vertical arrays and specific features of your Renkus-Heinz Line Array System will help you to operate these
products safely and obtain optimal performance.
The RHANGSTLA Tie Bar has 3 angle setting positions.
To set adjacent modules at 0° splay, align the bottom hole on the Tie Bar with the bottom hole in the lower module’s
receiving tube.
For medium splay (3° in “uptilt” position or 2° in the “downtilt” position) align the top hole in the Tie Bar with the top hole
in the receiving tube.
