At Renkus-Heinz we pride ourselves on innovation, and we invest heavily in our R&D department to ensure we stay ahead.

It is these innovations and discoveries that set Renkus-Heinz apart in what is a very crowded loudspeaker business.

Iconyx IC16-R-II with three beams

Beam Steering
Beam Steering technology allows Iconyx, IC Live and IC2 loudspeakers to tightly control the sound and place it just where it’s needed, on the audience, while keeping it away from other surfaces that may cause echoes and reverberation. Intelligibility is the key, and Renkus-Heinz Iconyx ensures every listener receives the best sound possible.

A simple, intuitive, interface to a complicated mathematical process our RHAON & Beamware software allows the designer to create multiple beams of sound, tailored to the room in question. Powerful FIR coefficients are calculated and downloaded into the loudspeaker's amplifier module turning the designed beams into reality. Inside the loudspeaker amplifier module each driver has it's own amplifier and DSP channel which, when loaded with the FIR filters, EQ and Delay, create the steerable beams.

To find out how it works in more detail here’s our Iconyx Whitepaper explaining the concept, the mathematics and the practical applications of Iconyx Beam Steering technology.

Solid Model of CDT-3 CoEntrant Driver

In our original CoEntrant designs, the output of multiple mid and high frequency transducers were integrated into a single acoustic source, with inherent alignment in both space and time.

In a visionary, yet logical next step, we applied these designs to create an entirely new type of wideband, high output, low distortion, point source transducer. It's no exaggeration to say that the patented CoEntrant Driver is the first truly new approach to converting electrical energy into sound in well over 50 years.

CoEntrant Drivers allow us to deliver maximum acoustic power from minimal enclosure dimensions, without sacrificing effective pattern control.

CDT Drivers are a standard feature in all our three-way cabinets.

Complex Conic Horns eliminate pattern flip

Complex Conic
The natural, transparent sound that has come to define Renkus-Heinz loudspeakers is a result of our unique Complex Conic Horn technology.

Complex Conic horns work with the spherical expansion of the acoustic pressure wave instead of trying to force it through a rectangular funnel like conventional designs. Complex Conic horns provide constant beamwidth, and as pattern control devices, they perform better over a wider frequency band than ordinary horns.

Complex Conic horns are used in all our loudspeakers, and that is why they sound more like studio reference monitors.

One problem conventional horns exhibit occurs at lower frequencies, where the wavelength of the sound waves exceeds any of the horn dimensions. As illustrated below (orange ellipse in the left graphic), conventional horns exhibit a phenomena known as "pattern flip". The coverage pattern rotates 90° or "flips" compared to its dominating (yellow) mid frequency pattern.

A second problem with conventional horns occurs at higher frequencies, where the dimensions of the horn are greater than the wavelength. Obviously, the diagonals of any rectangular shaped horns are longer than its sides. The greater dimensions impose greater control. This problem is illustrated at left by the blue "clover leave" pattern.

By contrast, the ComplexConic horn illustrated at right above, demonstrates much improved uniformity in coverage. Note: Not only do ComplexConic horns improve on the uniformity of coverage over a larger range of frequencies, they also deliver noticeably cleaner sound.

The TRAP TRue Array Principle has long been a cornerstone of Renkus-Heinz array design and optimization. The synergy of horn design, cabinet geometry, acoustic center placement and array processing all combine to give truly incredible results.

First employed in our TRAP series of products this technology was quickly adopted throughout our arrayable products giving rise to the creation of RPA (Reference Point Array) systems. Horizontal clusters that outperform their competition by virtually eliminating comb filtering between adjacent cabinets while also maintaining broad coverage at low-mid frequencies.

The latest incarnation of the TRue Array Principle can be found in the VARIA series where a true modular point source array is realized, in a package that’s incredibly easy to model, specify and install.
