Be prepared, because the LSiM707 will change the way you listen. Give
it some elbow room and its sheer power will rock you back on your
heels. Its level of realism will cause you to do a double-take: is that
live, or is it…? As a stereo pair, the LSiM707 is front-row-center for
hearing your favorite music again for the first time, with a wide,
enveloping soundstage, pinpoint details, convincingly real imaging, and
colorless reproduction. The LSiM707 home theater experience is so
palpable, so emotional, so engulfing that you’ll have to remember to
breath. The LSiM707 reignites the fun in your serious listening!
The ultimate statement of Polk's mission, the LSiM707 is like no
other loudspeaker in its price range. Featuring exclusive
state-of-the-art technologies, proprietary patents, and designed
in-house from the ground up, this is pure high performance audio of a
completely different stripe. Experience realistic, transparent midrange
reproduction with a 3 1/4-inch midrange driver of lightweight super
cell aerated polypropylene. Pinpoint detail is revealed by a 1-inch
ring radiator tweeter, a feature usually found on speakers costing much
more. The LSiM707 effortlessly achieves the deepest bass with dual
6x9-inch Cassini oval subwoofer radiators and Polk’s patented PowerPort®
venting, which eliminates performance-robbing turbulence at the mouth
of the bass port. Engineered into a sculpted, state-of-the-art
enclosure and finished like a beautiful piece of furniture, there is
simply nothing like the LSiM707.
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.
ring radiator tweeters extend top-end response for incredible
details and realistic imaging.
Newly designed Cassini
oval subwoofer drivers, 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.
Linear Motion voice coil design allows lots of movement in a
limited space, eliminating impedance and extending mid- and
Lightweight, rigid cast aluminum baskets are designed for precision
motor alignment with unobstructed
linear movement and ample venting.
motor optimization uses laser measurement technology to ensure a
smooth excursion path at either end of the volume spectrum for uniform
performance at both low and high volumes.
Polk’s proprietary, patented Dynamic
allows our engineers to design out distortion-causing driver and system
resonances, so you only hear the good sounds.
cell aerated polypropylene cone is the ideal balance of lightweight
stiffness (for more efficient action with less distortion-causing flex)
and superior damping properties.
Durable, computer-modeled, injection-molded butyl rubber surrounds
suppress unwanted cone resonances for a lifetime of reliable sound.
Exclusive, patented Orth
crossovers increase lower-order power handling and smooth the
impedance curve, for more efficiency and better high frequency response.
High quality, heavy duty LSiM enclosure construction
features 1.0" MDF on the sides, 3/4" MDF for the back and
bottom and 1 1/4-inch baffles, with substantial internal bracing and
separate interior cabinetry for each driver. These exceptionally robust
materials efficiently eliminate cabinet resonances and standing waves
for less distortion and more dynamic transparency.
Beautiful furniture-grade hardwood veneer cabinet finishes, with
sleek trim accents and no visible screws.
grilles lock in place magnetically, and never obscure your sound.
bass venting is Polk’s patented design for smoothly transitioning the
air flow from the port into your listening area, eliminating turbulence
and distortion, for bigger, more efficient, deep bass impact.
All Polk loudspeakers are timbre-matched
within their series, designed with the same components throughout, to
achieve seamless speaker-to-speaker blending effects in multi-channel
Dual gold-plated, professional-style 5-way
binding posts, for the most secure connection options.
Dual binding posts allow bi-amp
connections, for the ultimate in customized high performance audio.
Innovative no-tip hex-head floor spikes make speaker-leveling easy
on any flooring.
All Polk products are made using the best materials and the most
advanced manufacturing techniques. They pass the industry’s most exhaustive
quality tests, including drop testing, extreme signal response and
UV & salt exposure testing. Polk loudspeakers are built to perform
for a lifetime.
