Renkus Heinz CT7215-44AS Passive Speaker
Integrating Innovations for Breakthrough Performance
CT Series systems integrate Ralph Heinz's latest breakthroughs to achieve unprecedented performance. Because acoustics is a physical phenomenon, these advanced systems incorporate physical solutions to longstanding acoustical problems. TRue Array Principle (TRAP) enclosures ensure optimum coverage in tight-packed arrays. Complex Conic horns provide superior pattern control and more natural reproduction than conventional horns. Patented CoEntrant topology creates a new type of wideband, low distortion point source transducer. Doublet design provides exceptional low frequency control in the vertical plane, reducing spillover beneath the loudspeaker. The result of integrating these new ideas is a system that redefines reference quality in medium- to large-scale
sound reinforcement.
Advanced Complex Conic Horn Design
Designed around the spherical expansion of the acoustic pressure wave, Complex Conic horns combine constant beamwidth/directivity without the problems of conventional
rectangular horns. These unique waveguides eliminate low frequency “pattern flip.” The circular mouth has no corners to cause high frequency “feathering” and the resulting distortion. With extended pattern bandwidth, lower distortion, and minimal coloration, Complex Conic horns work better and sound far more natural than ordinary horns. Because they have no large planar surfaces, Complex Conic horns are less prone to in-band resonances than ordinary horns. To eliminate resonance-induced coloration, CT Series horns are molded from UHMW Polyurethane.
Patented CoEntrant Topology
Integrates the acoustic output of a 10" cone and a 2" compression driver into a wideband, high-power true point source. The result is a revolutionary new type of transducer that outperforms ordinary compression drivers in every dimension: power handling, frequency response, distortion, reliability, etc.
TRAP (TRue Array Principle) Operation
The Complex Conic waveguides used in these loudspeakers can also be easily rotated 90o within the cabinet. This converts the /64 and /94 loudspeakers into true TRAP modules that combine smoothly in arrays to drastically reduce comb filtering effects. The /44 and /44ASYM models are TRAP-able without rotation
