Product Description
-------------------
The Lsim705 fills your world with its wide, dynamic soundstage
and its capability to effortlessly achieve truly staggering
volume levels. The Lsim705 features the same component complement
as the larger Lsim707 loudspeaker, on a slightly smaller scale.
It includes a 5 1/4 inch Mid Woofer of lightweight super cell
Aerated polypropylene for smooth blending with its dual 5x7 inch
Cassini oval subwoofer radiators enhanced by Polk's patented
power port bass Venting. Its 1 inch ring radiator tweeter, a
feature usually found only in exotic speakers, reveals Pinpoint
details for realistic imaging. Use the Lsim705 in mid sized rooms
where you want the full on impact of the legendary Polk sound.

The ultimate statement of Polk's mission, the LSiM707 is like no
other loudspeaker in its price range. Experience realistic,
transparent midrange reproduction, pinpoint detail and the
deepest bass with the LSiM 707. Engineered into a sculpted,
state-of-the-art enclosure and finished like a beautiful piece of
furniture, there is simply nothing like the LSiM 707.
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.
* Cassini oval subwoofer, with more surface area than round
drivers, dramatically improve low-frequency response for deep,
well-blended bass.
* Our innovative overhung voice coil design augments the
excursion length for subwoofer drivers, increasing their
power-handling capabilities and enhancing bass response.
* Extended linear motion voice coil design allows lots of
movement in a limited space, eliminating 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.

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
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.
Extended Linear Motion (ELM) Voice Coils
Allowing lots of movement in a limited space, ELM voice coils
power the LSiM midrange and mid-woofer drivers to extend their
higher frequency response with much less impedance. (LSiM
subwoofers use overhung coils, which allow the larger excursions
and greater power handling necessary for big subwoofer
performance.)
The LSiM Enclosure
The enclosure is an integral part of the sound design of the new
LSiM Series. All LSiM cabinets are made of 1.0" MDF on the sides,
3/4" on the back and bottom, and wide radius baffles of robust 1
1/4-inch MDF. Substantial internal cabinetry, each driver with
its own separate asymmetrical chamber, increases efficiency and
banishes internal resonances and standing waves, for high power
handling and incredible smoothness. The narrow baffle with its
wide radiuses enhances the imaging for a very wide, deep and
well-defined soundstage.

Registration card Warranty* Speaker Warranty 5 years parts and
labor (original purchaser) *To ensure a valid warranty, Polk
loudspeakers must be purchased through an Authorized Polk home or
car loudspeaker Dealer (such as .com). (If you’re not sure a
dealer is "authorized," call Polk at 1-800-377-7655, and ask us.)
The warranty is not transferrable, that means it applies only to
the original purchaser. If you purchase your speakers from a
private individual, that product is considered "used" and has NO
factory warranty, no matter what the seller implies. The warranty
is VOID if the serial number of the speaker has been removed or
defaced. If you have any questions about your warranty coverage,
or you think you need service, call Polk Customer Service at
