model F-5000 Phase Aligned Array Speaker System

Direct Drive Membrane Tweeter.
By now,
most audiophiles understand the importance of phase accuracy. During a live
performance all the notes - or frequencies - produced by the musicians have
specific phase (time) relationship to each other. And the many overtones - harmonics -
within each note also have specific orders in time and strength. If
these subtle musical phase relationships are confused or lost, so is true
fidelity.
Loudspeakers,
because they operate simultaneously in the separate worlds of electronics,
mechanics and acoustics, have the worst problem with phase accuracy. And the
most difficult to correct, in the attempt to correct for phase aberations,
speaker manufacturers have produced an odd assortment of peculiarly shaped
enclosures and driver configurations. But these half-measures create as many
problems as they solve.
Only
Onkyo provides a total solution to the phase problem. The Onkyo Model F-5000
Phase Aligned Array is a three way
system whose individual drivers are inherently phase accurate because of their
radically difierent - and technologically superior - construction.
The tree
planar (flat-diaphragm) drivers in the Model F-5000 were developed through
laser interferometry and computer analysis of the phase randomizing break-up
modes in conventional driver cones. Onkyo's solutions for the F-5000 are
emboded in the diaphragms of the 12" bass and 4" mid-range drivers.
They consist of essentially flat annularly ribbed polyurethene/felted paper
patented laminations that are inert, stiff, and yet have exceptionally low
mass.
The
critical high-frequency reproducer (DDM - Direct Drive Membrane) in the F-5000
employs an extremely thin and light polyamide memnrane. The result is
electrostatic-like clarity, definition and center imagery, without the typical
electrostatic drive problems.
The
computer-developed crossover network, designed for the required phase
characteristics, employs only air-core inductors and Mylar capacitors.
Onkyo's
efforts and quality construction have resulted in smooth, wide frequency
response, flat amplitude and precise linearity. Thus, the sound waves that come
out of the system are almost mirror images of the sound waves that go into
them. The overall effect is one of clarity and transparency delivered from a
unit that looks as good as it sounds.
