Orpheus Apollo 'Signature' Loudspeakers
"SIGNATURE" LOUDSPEAKER UPGRADE
new "CCD" Crossover Technology
Fully Factory Sanctioned by Brad Serhan &
Apollo "Signature" Loudspeakers
The original Orpheus Apollo Loudspeaker is
now nearly discontinued (early January 2014) after 700 pairs were made.
For unusual reasons, the drivers used in the Apollo were of an order of
greater quality for a Loudspeaker that sold for AUD $1999 - and now that
quality can be untapped, but at an additional cost that could not have
been applied for a speaker selling for two thousand dollars in a very
tight market. This is an unusual opportunity.
You will need to secure a pair first - we will
try help you when able.
How does the performance compare when fully
upgraded? Like an astonishing speaker at virtually any
price. The 7" Midrange/Bass driver would not be out of place in speakers
costing tens of thousands of dollars. The Silk Dome Tweeter is the latest
in modern design that is a trend towards lager domes and large
roll-surround that also doubles as ring radiator and large double-chamber
with the lowest Fs resonance we have seen, period.
The upgrade features new internal silver-clad solid core copper wire
and the crossover is the latest in terms off research into speaker
behaviour that suppresses jitter effects, in fact the more correct
term for jitter is phase noise.
"CCD" Crossover refers to Clean Current
Drive technology - a new approach to Crossovers, indeed a new type of
Crossover that has been developed over the last 3-4 years.
For a long time it has been known, but largely
ignored, that it is the current through the Voice Coil
rather than the voltage across the Voice Coil, that makes a cone
move. Yet, when current and voltage are not properly in sync, then
jitter/phase noise is the result. Literally, the speaker produces copious amount of noise
patterns and results
in a major reduction is clarity and natural tonality. It makes the speaker
sound flat and uninteresting.
It is no secret that it is the Crossover that is
a major culprit, but also the drivers themselves don't help. The
driver that can be used with a Crossover technique that hugely suppresses
phase noise, has to have special characteristics and they have to be lower
in reactance that causes the driver to behave more like a voltage
generator and do so at their worst in the midrange and lower treble.
The result is an incredible increase in overall
clarity. Do you love vocal recordings, then you will love this
speaker. Do you appreciate a huge soundstage with both unbounded width and
height? Do you like hearing correctly proportioned instrument sizes within
that soundstage and a total natural and non-edgy delivery and fully
fleshed out tonal colours and natural overtones? Then this will be a
speaker that would not be normally available at this price.
Locking in the Crossovers. Both mechanical
High-Pass Filters (Box Alignments) and Electrical Filters (Crossovers)
can be current driven. When this is the case, both Box Alignments and
Crossovers can be driven by any Amplifier, regardless of its type - no
matter what it's output impedance is. So the Crossover does not shift and
tracks near perfectly well, even when Tube Single-Ended Amplifiers are
used, which typically have 5 Ohm Output Impedance or higher. This 'locking
in' can even be adapted to High-Order Crossovers, but won't have the full
CCD benefits - but at least the Crossovers stays where it should be.
Availability in late January 2014 expected.

components (subject to change as we will always be looking for ways to
