STLA/9 (PowerNet) ▪ STXLA/9 (Non-Powered)
LINE ARRAY LOUDSPEAKERS

OUTSTANDING SOUND QUALITY
UNEQUALLED VERSATILITY


The STLA/9 and STXLA/9 use advanced technology and application-driven engineering to bring vertical arrays closer to the ultimate reference point (reality) in demanding environments. Fully integrated electro-acoustic systems with all elements optimized deliver superior fidelity and coverage. Wherever the venue is appropriate for a highpowered vertical array, a high-power 3-way STLA/9 or STXLA/9 line array is the logical choice for demanding designers, operators and audiences.

STLA/9 and STXLA/9 Line Array Loudspeaker Modules

The self-powered STLA/9 and the non-powered STXLA/9 are the basic building blocks in the Renkus-Heinz STLA and STXLA Series of line arrays. Their unique design allows arrays of all sizes to be simply assembled and quickly installed safely and securely.


Co-Entrant Transducers & Isophasic Plane Wave Generators

STLA and STXLA line array modules are based on the new CDT1.5 high output CoEntrant driver with an advanced 6.5" carbon fiber cone and a unique neodymium HF driver with a 2.5" voice coil and Titanium diaphragm. Two CDT1.5뭩 are arranged vertically on individual Plane Wave Generator lenses with Path Length Equalization Technology, both feeding a common waveguide. This configuration maintains line array source coupling through the mid/high crossover for improved directivity in the vertical plane and a coherent wavefront throughout the mid and high frequencies. The combination of a single mid and high-frequency waveguide with closely spaced woofers creates consistent horizontal coverage from 200 Hz to 18 kHz.
Renkus-Heinz Engineering has developed unique technologies to optimize line array module performance. The CDT1.5 is a co-entrant driver that integrates a 6.5-inch carbon fiber cone and a 2.5 inch voice coil titanium compression driver. The output of this high output wideband point source is shaped by our Isophasic Plane Wave Generator with Path Length Equalization Technology to approximate a plane wave (less than 1/8 wavelength curvature).

Vertical arrays radiate a continuous midrange and high frequency wavefront whose curvature is the same as that of the array. This enables the designer to control dispersion over an extraordinarily wide range ?250 Hz to 20 kHz ?by varying the curvature of the array. Horizontal dispersion is also important: many line array modules produce a narrowing through the mid range transition from the woofers to the high frequency section.
The unique design of the STLA and STXLA modules avoids this by controlling horizontal dispersion from 350 Hz ?20 kHz using a common horn flare. This horn flare can be replaced in the field: 60? 90?and 120?patterns are available to suit different venues or different sections of the vertical array. Because there is no separate midrange section, the horizontal spacing between woofers is reduced so that dispersion is consistent from 200 Hz through crossover.
Applications

▪ Virtually any application where outstanding sonic performance is required and sound level and coverage needs cannot be satisfied with a conventional horizontal loudspeaker array.

▪ Sound reinforcement systems in large Houses of Worship, Performing Arts Centers, Sports Arenas, Theaters and other similiar venues.

▪ Portable "touring" sound systems for both small and large concert venues
