The vision behind the development of the new MAGELLAN line was
to create very powerful direct drive electro-dynamic drivers for all of
the models in the line, regardless of their specifi c frequency range.
Above all, the fi lter was designed primarily to give the fi nal product
the best possible musical characteristics. What makes the fi ltering
circuits in the MAGELLAN line unique is modeling the fi lter’s
crossover characteristics to those of the drivers in order to achieve a
very steep cutoff and an excellent phasing.
Furthermore, this technique avoids using additional electric
components and thereby compromising the signal quality.
The fi ltering on the new MAGELLAN line between the tweeter and the
midrange is 24dB/octave, and 12dB/octave between the midrange and
the woofer.
The filters used on the new MAGELLAN line make the
loudspeakers less susceptible to gaps in the sonic spectrum.
The loudspeakers’ natural frequency responses were modifi ed
digitally for a perfect match with its fi lter’s transfer function.
Furthermore, the drivers’ impedances were linearized for more
effi cient performance between the amplifi er and speaker. This
modifi ed impedance acts almost as a pure resistance, allowing the
amplifi er to work very effi ciently.
The TRIANGLE RPC TM system provides a reduction in both phase
distortion as well as speaker directivity. As a result, the position of the
listener will have little effect on the listening experience.
The MAGELLAN fi ltering system is made of high quality electrical
components (low inductance ceramic resistors, polypropylene
capacitors, large gage windings). The components are carefully selected
in order to meet the stringent manufacturing requirements of our end
products.
