drive unit technology
Proteus is a three-way design using two
180 mm bass units, one 150 mm midrange
unit and a 20 mm silk dome tweeter.The
drive units have been optimised to maximise
their performance within their respective
operating bandwidths. A detailed description
can be found in the technical data section at
the end of this manual.
high quality vibration isolated crossover
The crossover is mechanically de-coupled
from the sub-structure of the loudspeaker to
prevent microphony in the components.The
crossover network is mounted in the
underside of the main loudspeaker enclosure
in its own separate sub-enclosure.
This no compromise crossover guarantees
that sound energy is split between the drive
units without affecting the purity of sound.
More details can be found in the technical
data section at the end of this manual.
OFHC loudspeaker connection terminals
By fitting proprietary OFHC, gold plated
binding posts, a clear sonic improvement
has been achieved compared to the typically
used alternatives employing high copper
content alloys. Furthermore, no nickel -
plating has been used between the OFHC
foundation and the gold finish as it adds
distortion and colouration to the sound.
Whilst this will lead, in the long term, to
some discolouration of the binding post due
to copper atoms partially diffusing into the
anti-corrosion gold layer, the customary
nickel plate interlayer is well known (as a
ferro-magnetic and hard oxidised metal) to
affect sound quality adversely and was
therefore eliminated.
single input connection
After extensive research into the sound
quality of the F1 AvantGarde loudspeaker, it
was discovered that the potential benefits of
multi-wired terminal connections were
outweighed by the losses incurred in their
implementation, e.g. additional contact
interfaces and electrical connection straps.
In addition, even with top grade power
amplifiers, star grounding improved the
dynamics and transparency.
'Peripheral Slot Technology' reflex port
The bass units are reflex tuned in their
enclosure volume by a downward firing
port tube employing 'Peripheral Slot
Technology'.The low frequency sound
pressure from the port is distributed into
the room evenly through a slot to reduce
standing waves) between the bottom of the
enclosure and the top of the plinth.This
prevents audible chuffing and higher
frequency harmonic distortion from the
port that would otherwise degrade the
sound quality of the system.
