3-Way Transitional Speaker Design: The Imagine C3 is a
true 3-way transitional driver design; unusually sophisticated for a center
channel speaker. The C3 includes two 7" compressed felt/fiberglass woofers, both
active at lower frequencies and with different low pass filter frequencies to
maintain proper power response, as well as titanium dome tweeter. The specially
developed 3.25" midrange driver is unique to the Imagine C3 and is responsible for the
excellent speech articulation of this speaker.
High Resolution Tweeter: The Imagine C3 is using a
hand-selected version of PSB's famous titanium dome tweeter. This 1" dome
features a neodymium magnet, high temperature voice coil and ferrofluid cooling,
allowing it to keep pace with the high power handling of the rest of the
speaker. Several years spent perfecting the production process has resulted in a
tweeter with extremely smooth response and amazingly low distortion compared
with other well-known tweeter designs. The integrated 'phase plug' is
ingeniously designed to extend high frequency response while also creating an
'air spring' that effectively dampens the metal dome's 'oil can' resonance.
Although this resonance is beyond the audible range, if not well suppressed it
can affect the audible range. Excellent power handling allows PSB to ideally
place the crossover point at 1,800Hz, which enhances the dispersion and
integration with the midrange driver.
Advanced Driver Technology: Proven engineering combined
with advanced technology in PSB's all-new drivers reduce distortion and respond
more faithfully to musical transient, which is accomplished in two ways.
Firstly, a copper cap is precision fitted over the pole piece of the motor
structure to dramatically reduce 3rd harmonic distortion. Secondly, a
symmetrical drive design is used to create a more uniform magnetic field in the
motor (driver) coil which makes the cone motion more linear by reducing 2nd
harmonic distortion, especially at high volume levels where the cone motion is
greatest. The woofers and midrange utilize polymer coated felted fiberglass
cones mated to a high temperature fiberglass voice coil. Rubber surrounds and a
highly rigid non-resonant die cast aluminum alloy chassis provide precision
alignment of all speaker components for high performance and excellent
reliability. Combined with amplitude-perfect acoustic Linkwitz-Riley 4th order
crossovers, these advanced drivers provide the lowest distortion and highest
power handling of any PSB center channel speaker.
Industrial Designed Enclosure: The sleek and
distinctive Imagine enclosure was designed by the renowned industrial designer,
David Farrage of DF-ID, and carefully engineered by PSB. The Imagine C3 employs
seven layers of MDF (a dense, non-resonant wood material) and a unique process
that employs space-age materials to create a beautifully curved, yet
acoustically inert structure. The front baffle is a massive 2" thick MDF panel
that provides a solid foundation for the drivers. The carefully sculpted trim
rings around each driver provide a perfect low diffraction transition to the
driver cone enhancing off-axis performance while hiding the fixing hardware and
dampening unwanted vibrations. The hand-finished cabinet is available in piano
high gloss black and in book-matched cherry veneers with a high gloss varnish.
Bass Port w/ Plug: The Imagine C3 center channel loudspeaker
employs a bass reflex enclosure with a rear-firing port for greater efficiency
and bigger bass response. A tuning plug is included to adjust bass output for different placement options;
the tuning port helps to tighten and less bass response.
Dual Binding Posts: The dual binding post input terminals
are located on the rear of the speaker cabinet. The two sets of binding posts
are shorted together by a gold-plated jumper. With the jumper removed the
Imagine C3 can be bi-wired or bi-amplified. The binding posts will accept spade
connectors, single or dual banana plugs, pin connectors, and bare wire up to 8
