Product Description
-------------------
There's no doubt that bookshelf loudspeakers offer greater
placement flexibility than floor standing loudspeakers but
usually with a trade off in performance. Not so with the Lsim703
bookshelf loudspeakers. You'll be delightfully surprised to hear
the kind of performance that befits our ship loudspeaker
line. With a 6 1/2 inch Mid Woofer, 3 1/4 inch midrange, both of
lightweight super cell Aerated polypropylene, combined with the
enhanced deep musical bass response of Polk's patented power port
bass Venting system, The Lsim703 delivers a wide, deep, dynamic
soundstage. The addition of the proprietary 1 inch ring radiator
tweeter adds Pinpoint detail for realistic imaging. With the
performance of the groundbreaking slim Series in a smaller,
flexible bookshelf speaker format, The Lsim703 gives you the best

key features
* Polk's exclusive dynamic sonic engine design optimizes the
midrange driver and the ring radiator tweeter in separate
interior chambers for improved transient response, superior
imaging and greater horizontal off-axis response.
* Our innovative overhung voice coil design augments the
excursion length for subwoofers, increasing their power-handling
capabilities and enhancing bass response.
* Extended linear motion voice coil design allows lots of
movement in a limited space, reducing impedance and extending
mid- and high-frequency response.
* Lightweight, rigid cast aluminum baskets are designed for
precision motor alignment with unobstructed linear movement and
ample venting.
* Polk's proprietary, patented Dynamic Balance® technology
designs out distortion-causing driver and system resonances, so
you only hear the good sounds.
* Super cell aerated polypropylene cone is the ideal balance of
lightweight stiffness (for more efficient action with less
distortion-causing flex) and superior damping properties.

technology
Dynamic Sonic Engine
This is a molded enclosure within the cabinet that houses the
super-accurate ring radiator tweeter and the extended motion
midrange driver in their own separate, tuned compartments. This
aligned, optimized array contributes to wide, uniform dispersion
in the critical 200Hz - 2kHz range. The dynamic sonic engine, in
turn, lives in a separate, rigidly braced
enclosure-within-the-enclosure. This separation and specialized
tuning measurably reduces performance-robbing back wave
reflections. The result is astonishing detail and realistic
imaging, with improved transient response, exact timbre-matching,
and greater horizontal off-axis response.
Enhanced Ring Radiator Tweeter
Our engineers took the ring radiator tweeter, usually seen in
only the most exotic speakers, and found way to improve it. They
reshaped the tweeter's bullet-shaped phase plug to eliminate
horn-loading and improve dispersion. Redesigning the tweeter
faceplate and the diaphragm added efficiency. Finally, they gave
their new ring radiator tweeter its own tuned enclosure within
the dynamic sonic engine. This enhanced ring radiator boasts
higher power handling, extended dynamic range, better dispersion
and extended top-end response
Klippel Optimized Dynamic Balance® Transducers
All transducers are developed using our proprietary Dynamic
Balance technology to reduce or eliminate unwanted material and
interface resonance that color the sound. Klippel measurement
systems are employed during development to ensure the speaker
will deliver life-like highly detailed playback at both low and
high volumes levels.
Super Cell Aerated Polypropylene Cone Material
The perfect cone material is lightweight (for faster, more
efficient action) and stiff (for less distortion-causing flex),
with enough internal damping to suppress and offset any
limitations of its lightweight stiffness and our super cell
aerated polypropylene cone material is about as perfect as it
gets. It's the ideal balance of lightweight stiffness with high
damping, along with good resistance to moisture, UV and
temperature extremes. Our drivers are fast, linear and nearly
resonance free.
