Driver Technology
True-to-Nature Sound: The PSB Imagine W1 on-wall loudspeaker produces
a large soundstage with true-to-nature sound. Engineered with highly acclaimed
audio excellence and research, the Imagine W1 on-wall speaker will deliver wide
frequency and dynamic range, natural tonal balance and precise spatial imaging
needed to make both music and movies lifelike and enjoyable.
Note: The PSB Imagine W1 performs best when complemented with a
powered subwoofer (sold separately). Check out these
powered subs from PSB.
Two-Way Design: The PSB Imagine W1 employs a two-way
speaker design. It houses a single 1" ferrofluid-cooled titanium dome tweeter
with a neodymium magnet and two 4" clay/ceramic filled polypropylene woofers
with rubber surround. The result is startlingly big and commanding sound with
fine detail and emotion.
- 1" Titanium Dome Tweeter: The 1" titanium dome,
ferrofluid-cooled tweeters use a neodymium magnet structure to help extend
the frequency response at both ends for effortless, airy top octaves and
smooth, uncolored response. The tweeter feature a specially engineered
"phase plug" or shield that extends the high frequency response by dampening
the tweeter's resonance and preventing phase cancellation in the top musical
octave. The clear delicate sounds produced by this remarkable tweeter
accurately reproduce all the musical detail contained in your favorite
movies and music.
- Dual 4" Clay/Ceramic Filled Polypropylene Woofers: Dual
4" woofer cones are clay/ceramic filled polypropylene to optimize the
combination of stiffness, internal damping, and low mass. The woofer's
magnetically neutral polycarbonate basket contributes additional stiffness,
and the bullet-shaped phase-plug enhances linearity at higher frequencies.
Passive Radiators: Bass is enhanced by dual passive bass
radiators (PBRs) that extend the bass reach of the speaker by doubling the
output of the woofers at the lowest frequencies.
Crossover Network: One of the most critical aspects of
speaker is the crossover network, where the final voicing and integration of all
the elements of the design are determined. Even proximity to the wall behind the
speaker has an effect that must be considered when fine tuning the crossover. PSB engineers designed the crossover
frequency very low relative to the woofer size in order to provide the same
sound no matter where the speaker is placed. The crossover is a 2-way acoustical
fourth order Linkwitz-Riley type with a 24 dB/octave slope. The tweeter and
woofers are crossed over at 2,300 Hz.
Enclosure Design
Aluminum Cabinet: To gain maximum internal volume (necessary for good
sound and deep bass response) a special aluminum cabinet was developed that
minimizes external bulk and maximizes strength and internal volume. A
non-resonant MDF baffle mounts the driver units in carefully optimized positions
for an ideal dispersion of sound to the listener. Attention-to-detail is extreme
with soft rubber trim rings that not only give sleek look, but also control
dispersion of sound and add further damping of spurious vibrations.
Cloth Grille: An attractive cloth covered metal grille is transparent
to sound while serving to integrate the speaker with your home décor.
Connections
Spring-Loaded Posts: The Imagine W1 on-wall loudspeaker is fitted with
a pair of spring-loaded posts that accept bare wire (up to 14AWG),
pin-connectors, and banana plugs (single/dual).
Color-Coded: The spring post speaker terminals are
color-coded (red/black) for easy identification between positive and negative.
Mounting Options
Applications: The Imagine W1 is a single channels speaker that can be
oriented either vertically or horizontally and be used as a front left, right,
center, or surround channel speaker. Multiple Imagine W1 models can formulate a
complete system or the speakers can be combined with other PSB
In-room or
In-wall/In-ceiling speakers (sold separately) to create a customized Home Theater
solution.
Wall-Mount: The Imagine W1 includes is a sturdy wall-mount bracket. At only
3" deep this speaker hugs the wall, integrating perfectly with popular
flat-panel TVs. The W1 can flank the TV to the left and right, and can also be
oriented horizontally below the screen as a center channel. The mounting bracket
provides various keyhole slots to mount the speaker to your wall, either
vertically or horizontally (mounting screws not supplied). The wall-mount
bracket adds 0.25" to the depth of the speakers.
Table-Top Placement: The provided feet allow for the speaker to be
placed on a tabletop below your flat-panel television in a center channel orientation. Depending on
the way you install the feet, this will set the speaker at 90-degrees or 75-degrees (tilted back 15-degrees) from the table surface. To install the tabletop feet, attach the feet to the threaded
inserts on the back of the speaker using the provided 1/4"-20 threaded bolts.
The table-top feet add 0.1875" to the height and 0.5" to the depth of the
speaker.
