Accurate Stereo Audiophile
The Cyclops II is a visually stunning loudspeaker for the purist. Being a
smaller loudspeaker, it's most comfortable with small ensemble classical, jazz
and vocal music. The unique bi-polar design and small point-source drivers
provide a realism, purity of sound and immediacy that might prove extremely
difficult to find in any loudspeaker, at any price.
The Cyclops II is a reworked and slimmed down version of our maiden product,
the Cyclops. It too is a mass-loaded tapered quarter-wave pipe with a tuned
frequency of 58 Hz. The loudspeaker utilises professional full-range drivers
with specially vented neodymium magnet motors and Kevlar cones, rated for 20W
continuous (RMS) output. The drivers are arranged in a bi-polar configuration in
order to alleviate the baffle step response of the forward firing drivers as
well as to aid in ambience retrieval. The loudspeakers are damped with no less
than five types of absorbent materials to optimise frequency response, damping
and distortion reduction mechanisms.
Each loudspeaker is supplied with an integral concrete base with provision for
filling with gravel or lead shot to aid with damping loudspeaker vibrations and
tightening the low frequency response. Each base is fitted with removable
isolation spikes. The pipes are manufactured from natural wood (currently Iroko
or African Rosewood) and medium density fibre board sandwich for enhanced
performance and damping. The pipes each have their own filter unit and baffle
step correction circuitry. Standard bi-wire cables plug into four sturdy
three-way gold plated binding posts fitted to the rear of each loudspeaker, just
below the aft-firing driver. Lead free silver bearing solder is used throughout.
The filter units are now fully passive: a notch filter for driver equalisation
and forward/rear frequency distribution is combined with a baffle step corrector
circuit. A higher efficiency variation is available for valve amplifiers.
Coupling capacitors are oversized polypropylene units designed specifically for
audio applications, arranged as a series filter, minimising signal distortion.
The passive circuit uses both audio grade wire wound resistors and ruthenium
oxide cermet high frequency resistors, which minimise high frequency losses in
the crossover. The filter capacitors on the notch filter are polycarbonate units
known for low dissipation factors and a gentle response curve that gives an
almost valve-like character to their sound. These capacitors have been
discontinued and are hard to come by. Critical components (the
Danish-manufactured air core inductors and the cermet resistors) are silicone
damped to reduce microphonics. The single bipolar capacitor in the circuit is
bypassed with a polypropylene unit to minimise inductive and memory effects.
The filter is housed in a hand-made Beech frame with ABS top and bottom. Gold
plated connectors are provided on the front and rear panels.
Performance has to be heard to be appreciated.

I thought to slip in the Cyclops II here, a bi-pole tapered pipe, by PHI Hi-Fi
Innovation as it happens to be one of the best full-range designs I have ever
AVSA MAY 2008 - REVIEW BY DEON SCHOEMAN
"...the PHI 58.40b Cyclops is a remarkable speaker in many
respects. Its application is limited, and it requires careful matching of
ancillary equipment. But in the right electronic company, with music suited to
its particular talents, these speakers deliver a world-class performance."
