The Cortex 11W was developed as the optimum active speaker solution for home cinema and presentation systems. It is a 2 1/2-way speaker with a D\'Appolito look that has integrated screw fittings on the back for various brackets from the K&M range. This allows it to be mounted flexibly on the wall or suspended from the ceiling. But the 11W also cuts a slender figure when standing on its own feet.
Its slim shape and versatile suspension options make it the ideal speaker for high-quality home cinema systems:
- Speaker for high-quality home theater systems
- Replacement for ELA (100V) line speakers
- Speakers for churches and similar speech transmission systems
- Audio front end for presentation rooms
- Speakers to the left and right of flat screens on the wall
- Monitoring monitor with limited installation options
- Speakers for restaurants and business premises with high sound requirements
- Loudspeakers for compact hi-fi systems for simply listening to really nice music
AMT Tweeter
The Air Motion Transformer (not to be confused with the visually similar \"ribbon\") is a special sound transducer whose basic principle was developed by Dr. Oskar Heil. Unlike conventional cone or dome tweeters, which in principle use a piston-like back and forth movement to displace or suck in air, here an accordion-like folded foil is moved in the magnetic field, which pushes air out of its gaps or sucks it in. This principle means that less mechanical material movement is required to generate the same sound pressure and acoustic distortions are reduced. Due to their geometric design, the sound of AMTs is somewhat more focused vertically as the frequency increases. This can have sonic advantages because reflections from the floor and ceiling are reduced.
DSP
With ABACUS active loudspeakers and subwoofers, the crossover, i.e. the division of the signals according to the frequency range, and the optimization of the loudspeaker characteristics are always carried out actively, i.e. before the power amplification (unlike with passive loudspeakers, where the already power-amplified signal is separated and influenced by coils and capacitors). Depending on the loudspeaker series and the associated complexity and price-performance ratio, ABACUS does this with analog filter circuits (e.g. C-Box, Trifon, Oscara) or, as here, with a digital signal processor.
The built-in digital signal processor (DSP) performs a wide range of different tasks without increasing the complexity of the components immeasurably. The DSP used in ABACUS provides countless filters, takes over the function of the active crossover, linearization of the frequency response, phase and delay corrections and, on top of that, switching and control functions. Once the signal has been digitized, it can be processed as required without any loss of sound quality, because every filter and every control function is then just a computing task that is processed at a high clock frequency. The time delay caused by the processor is only approx. 0.3 ms.
