Thank you for purchasing the TAG McLaren Audio loudspeaker
Calliope AvantGarde.We are convinced Calliope will give you
many hours of listening pleasure.
leading-edge technology
Calliope is a hi-performance, two-way, fourth order reflex-
loaded, aluminium technology loudspeaker, capable of
reproducing music with outstanding clarity and transparency.
Calliope is ideal for high quality two channel stereo and home-
cinema applications.
enclosure technology
Calliope employs hi-performance materials
avoiding the traditional wooden cabinet to
eliminate the unwanted sonic signature of
energy re-radiation. A pre-stressed, curved
profile forms a very stiff, single-piece alloy
extrusion which is further reinforced with
the addition of aluminium alloy end-caps
secured with tie-bolts.This creates a
structurally inert and inherently well
damped enclosure which ensures that
acoustic energy is created by the drive
units and not the enclosure. Preventing
the enclosure from flexing and re-radiating
energy reduces distortion and coloration
offering a neutral and accurate portrayal
of the performance.
optimised dispersion enclosure
geometry
The geometry of the enclosure has been
carefully designed to optimise the dispersion
of sound energy. Calliope generates an even
and consistent energy output both on and off
axis resulting in a solid and accurate image.
hi-specification drive unit technology
Calliope’s drive units have been designed to
optimise their performance within their
respective pass-bands.The 150 mm
bass/midrange unit employs a woven glass-
fibre cone to create a stiff, yet well damped,
diaphragm that remains pistonic through the
pass-band. A phase plug has been employed
in place of the commonly found dust-cap.
This phase plug does not contribute to the
moving diaphragm assembly. It therefore
offers considerable benefits over an orthodox
dust-cap: reduced moving mass, improving
transient performance; improved off-axis
frequency response, providing a wider sound-
stage; no physical contact with the diaphragm,
preventing a mechanical impedance mis-match;
and a smooth frequency response roll-off.
