Pierwszy pasywny, kompaktowy system kardioidalny d&b CCL na ISE 2025

Line array systems that offer dispersion control down to the lowest frequencies are quite complicated devices that, in addition to having a larger number of speakers than in "ordinary" systems, must also have an appropriate algorithm implemented for these transducers. Signals reaching them must not only be appropriately filtered in terms of frequency, but also delayed/phase-matched to the others. In systems with a cardioid dispersion characteristic, this has so far been solved by processing signals in DSP, which also involved the appropriate number of amplifier channels that had to be "dedicated" to powering a single module. Finally, ON appeared, i.e. the CCL system from d&b audiotechnik, which is not only cardioid and compact in size, but also requires only one amplifier channel per module to "drive" it. The CCL system presented at ISE 2025 is the first member of the CL family. It is designed to handle small and medium-sized events - which should come as no surprise, considering the size and transducers used. It currently consists of three members - two wideband line-array modules (CCL8 and CCL12), differing mainly in the horizontal dispersion angle (80 and 120 degrees, respectively) and the compact CCL SUB subwoofer. The latter is of course also a speaker set with a cardioid dispersion characteristic, in which two drivers work - 15 and 10-inch - which allows it to "produce" a maximum SPL of 132 dB. The larger driver, playing forward, works in a bass-reflex configuration, while the "rear" 10 is placed in a two-chamber bandpass part of the housing. 🎛 Key Features of the New d&b CCL System ✅ The first fully passive cardioid system – effectively reducing sound to the rear while maintaining full power to the front. ✅ Inspired by the SL series – a smaller version of the legendary GSL/KSL/XSL system. ✅ Cost optimization – all sound elements are powered from a single channel, which reduces installation costs. ✅ Perfect for festivals and closed spaces – eliminates noise outside the audience zone, improving sound comfort. ✅ Advanced acoustic engineering – unique resonance chambers and bass reflex system ensure precise sound direction. The new d&b audiotechnik system is a breakthrough in sound directionality management and reduction of unwanted acoustic reflections. Both the CCL8 and CCL12 full-range modules are two-way passive designs housing two forward-firing 7" neodymium LF drivers, two side-firing 5" neodymium LF drivers and two 1.75" compression drivers mounted on a dedicated waveform shaping device. The cylindrical wave segments emitted by each module sum coherently into a single coherent waveform. The angles between adjacent modules can be set from 0° to 14° in 1° increments. The housing of the modules is injection molded (ABS polycarbonate), with a 2K impact and weather resistant finish. The front and sides of the housing (speaker outlets) are protected by a rigid metal mesh, backed with an acoustically transparent and waterproof fabric. The full-band modules cover the range 58 Hz -18 kHz (-10 dB), and are capable of producing a maximum SPL of 137/136 dB (CCL8/CCL12), when powered by D40/D80/D90 amplifiers. The weight of a single module is less than 18 kg. 00:00 Introduction – the new d&b cardioid system 00:35 How does the cardioid technology work in the new model? 01:45 Advantages over traditional sound systems 03:00 Ideal applications – festivals and enclosed spaces 04:35 Advanced acoustic engineering and precise directivity 06:00 Summary and market availability 🔹 More information about d&b audiotechnik news: https://www.infomusic.pl 🔹 Subscribe to InfoMusicFilms to stay up to date with ISE 2025 news: https://www.youtube.com/user/InfoMusi... 🔹 Leave a comment: Do you see any applications for cardioid systems in your work? #dbaudiotechnik #ISE2025 #Sound System #Cardioid #EventAudio
