SA-WX700 is a powered subwoofer that packs a Dual
10-inch driver respectively in a bass-reflex (vented)
cabinet. An onboard amplifier delivers 250 watts
of power to the driver. Supports both line-level
and speaker-level inputs, as well as a line output
for connection to additional subwoofers for even
more bass. The crossover is variable from 50-200
Hz. This will help you match them to the bass characteristics
of your main speakers. Also features a phase invert
switch allowing you to correct any phase conflict
that may occur between the sub and your satellite
Oriented Polyolefine (HOP)
A better material
for better sound. The dynamic range of Dolby Digital
sound tracks places stringent demands on the speakers
that reproduce it. That's why Sony developed an
exclusive loudspeaker cone material: Highly Oriented
Polyolefine (HOP). It's extraordinarily strong,
yet amazingly lightweight (up to 30 times more rigid,
per unit weight, than polypropylene). You get dynamic
sound with low distortion and extraordinary transient
response. HOP cone material combines high strength,
low weight and low resonance, resulting in improved
transient response, higher power handling, and flatter
With the Dolby Digital system, the surround
channels are reproduced in full stereo, with the
same full frequency response and dynamic range as
the front. That's why Sony builds receivers with
just as much power to the surround channels as to
the front. And that's why their speaker systems
offer the same quality front and rear.
Speakers placed too close to the TV
can cause the pictures to bend and colors to bleed.
That's why Sony bookshelf, floor-standing, front
and center speakers all incorporate magnetic shielding.
It cancels out magnetic fields and resulting interference.
You can place the speakers anywhere - even directly
beside your TV - without picture distortions and
Super Active Woofer Design
It might be hidden
from view, but an important element of today's best
home theater systems is the subwoofer. It's a specialized
speaker that handles only the deep bass. And it
helps put the finishing touch on everything from
explosions and car crashes to film scores and symphonies.
At these low frequencies, bass appears to come from
everywhere. This "omni-directional" characteristic
lets you position a subwoofer anywhere in the listening
room - and still get proper surround sound imaging.
Sony subwoofers are "active", meaning
they have built-in amplifiers for prodigious power.
They also use Sony's proprietary SAW (Super Active
Woofer) enclosure design, enabling them to provide
deep, powerful bass from compact, space-efficient
