RPC

Regulated Phase Crossover

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

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.
