Unique worldwide: symmetrical crossovers with ultrasteep slopes
The human ear can detect 10 octaves reaching from 16 Hz to 16.000 Hz. As there are totally different requirements for bass and highs response it makes total sense to divide the audible spectrum into several parts and use several specialized drive-units to reproduce the whole audible spectrum. To coordinate the interaction between the different drivers a frequency crossover is needed which allocates each frequency range to its corresponding drive-unit. The problem is that the separation between the single frequency ranges is not infinitely steep but very flat! This results in a big frequency overlap of the single units.
As all standard crossovers work with a slope of 6 dB/octave only it appears that there is an overlap region where the different drive-units radiate simultaneously even though they are totally different in size and on different geometrical places at the speaker baffle. It is quite obvious that this overlap leads to distortions in amplitude and phase and thus changes the impulse and frequency response of the whole loudspeaker to the worse!
Within the last years we have developed a new analogue crossover technology which is able to create a phase-linear filter with a slope of more than 50 dB/octave. This is very, very close to the theoretical ideal of an infinite slope! So the woofer radiates bass, the midrange driver mids and the tweeter only highs. Minimum overlap appears! Impulses stay impulses!
Moreover, our crossovers are built up symmetrically so that the electrical interaction between the loudspeaker's electro-magnetic feedback to the driving amplifier is significantly reduced. This leads to an amazingly clean and transparent sound
