Flex Array Concepts

The Flex Array system is a modular flexible array loudspeaker system designed to deliver

extremely high fidelity audio in a range of medium scale fixed and portable sound

reinforcement applications.

Flex Array combines elements of line array theory and virtual point source theory in one

loudspeaker product, and for the first time offers virtually unlimited flexibility in adapting to a

huge variety of venue types and audience areas.

The Polyhorn™ Concept

The patented Polyhorn™ effectively solves several of the problems associated with

conventional exponential horns: namely the tendency to „beam‟ with increasing frequency;

and the undesirable comb filtering effects generated between adjacent devices due to the

variable curvature of the wavefront caused by the horn‟s geometry.

The Polyhorn™ is split into multiple cells, or individual „hornlets‟, which connect the

diaphragm to the horn mouth. Dividing the multi-cellular horn into multiple tapered

waveguides guarantees that the path length of each micro-horn is equal from the surface of

the driver diaphragm to the horn mouth, and ensures that all frequencies from all parts of the

diaphragm arrive at the horn mouth together. This provides the wavefront with uniformity of

phase.

The Polyhorn™ geometry ensures that the sound wave does not suffer from edge-diffraction

effects which have a tendency to confuse the directionality of the sound source.

Each cabinet in an array containing Polyhorn™ devices contributes to the generation of a

single, cohesive, and more or less continuous wavefront without noticeable comb-filtering

effects. In addition, the Polyhorn design offers the possibility of locating the acoustic centre

well behind the motor system and even the enclosure.

The Polyhorn™ devices exhibit a sharp cut-off at the edges of the dispersion pattern, making

it possible to achieve seamless coverage of a venue with minimal destructive interference

between elements, irrespective of how many individual enclosures are deployed in the

cluster. Because of the Polyhorn™ design‟s sharp cut-off, its array angle can in practice be

taken as being the same as the dispersion angle.

The Polyhorn™ design allows the extension of an application central to Turbosound‟s

philosophy –the use of cone drivers to cover mid-range (especially vocal) frequencies and

the freedom to apply relatively high crossover frequencies in order to minimise the distortion

common to metal-diaphragm compression drivers. The Polyhorn™ is employed in the high-

mid section of the Flex Array TFA-600H, loading a custom-designed 6.5” high power

neodymium drive unit.

The Dendritic Horn

The patent-pending Dendritic HF horn utilises the same essential acoustic principle as is

employed in the Polyhorn: namely the application of equal path length hornlets to generate a

phase-coherent wavefront at the horn mouth. An extension of the principle allows the

Dendritic horn to act as the waveguide for a 1” throat compression driver, and key to the

operation of this new approach is the divide-by-two rule. Each section of the Dendritic

waveguide is split exactly two ways, ensuring that the signal in each leg is identical. In this

manner the output from a single compression driver is spread evenly across sixteen small

outputs.

Although adaptable to a range of output configurations, the Dendritic horn lends itself most

naturally to a slot output. By virtue of its tightly contorted pathways, the Dendritic creates a

very compact device, typically cutting 40% off the length of the external envelope.

The Flex Array Mid/High Waveguide

The Flex Array TFA-600 combines both Polyhorn and Dendritic horn technologies in a single,

physically aligned mid/high waveguide with equal path lengths, which produces a phase-

coherent wavefront at the horn mouth. The Dendritic horn‟s compact dimensions allows the

high frequency driver to be located directly in front of, and mounted concentrically with, the

high-mid frequency driver. The horn‟s shallow geometry, comprising the combined horn and

the concentric mounting of the mid frequency and high frequency drivers, results in a very

compact enclosure with a depth of only 560mm (22”). This is beneficial both for keeping

cluster footprint small and is also a convenient dimension for trucking.

The combined waveguide is square in section, allowing it to be rapidly and easily removed

and rotated within the enclosure to suit the intended application. In this way the 75°

horizontal by 16° vertical coverage pattern can be readily transposed relative to the

orientation of the cabinet.

The Loudspeaker Management System (LMS) Concept

Turbosound Loudspeaker Management Systems are more than just electronic crossovers. As

well as steep slope active filters and high performance limiters, they provide full digital

alignment of all components in the loudspeaker enclosures, to ensure coherent acoustic

output. They also incorporates a number of features which contribute to overall system

reliability and ease of setting-up and use.

All system parameters such as crossover frequencies, limiter settings, and equalisation can

be simply called up from a factory-preset menu, making it possible to maintain consistent

and repeatable system performance.

Because the power amplifiers can be included as part of the audio system, the controllers

utilise output limiters which are matched to the system requirements, being preset to prevent

the amplifiers from clipping under normal operating conditions. Inputs and outputs are fully

balanced, providing isolation between the controller and the amplifier inputs. These factors

contribute to high reliability in the adverse circumstances often encountered under arduous

touring conditions.

In addition, LMS-D2X series controllers are equipped with built-in network capability,

allowing maximum control and flexibility over the loudspeaker system‟s performance and

security.

LMS-D2x Loudspeaker Management Systems

Use of Turbosound loudspeaker management systems ensures accurate time-alignment of

the system drive units and also provides a facility for users to select additional delay, either

to compensate for physical displacement of ground-stacked bass enclosures relative to flown

high packs, or to provide full range delay for correct image localisation or use in distributed

systems.

Power Amplifiers

In addition to the Turbosound T-series amplifiers recommended for use with Flex Array

systems, the following other power amplifier brands provide sufficient performance and

mechanical compatibility to perform well with Flex Array loudspeaker systems:

MC2 E series

Lab Gruppen FP series

Crest Pro series

QSC Powerlight II series

Digital Controllers

In addition to the Turbosound LMS-D24 and LMS-D26 loudspeaker management systems, the

following digital crossover has been tested and is recommended for use:

XTA 4 series controllers

Self-Powered Loudspeakers

Flex Array series cabinets are optionally available with integrated networkable Class D

amplifier modules in a self-powered format, taking consistent performance and ease of use

to a new level. Featuring lightweight high-power amplifiers using 96kHz DSP and operating

at better than 90% efficiency, self-powered Flex Array products eliminate the need for

separate amplifier racks and controllers, as well as the attendant cabling.

Due to their extremely high efficiency and modern, high performance power supplies, the

amplifier module only adds a few kilos to the overall net weight of the loudspeaker.

The sophisticated DSP allows multiple internal preset recall either via the rear panel or over a

remote link.

Self-powered loudspeakers can be conveniently controlled and monitored over a network

with a PC running TurboDrive™ software.

Class D amplifier modules can be retrofitted to non-powered enclosures in place of the

Speakon connector panel, providing a quick and effective upgrade path.
