Polk LSIM704 Centre (Black)

The Smaller LSiM Center Channel Speaker

Features:
Dynamic Balance
PowerPort Bass Venting

The All Star Center
Capable of making quite an impact in your home theater system. It produces the kind of wide, deep soundstage and life-sized imaging that puts you in the middle of the action on your TV's screen.

PowerPort® technology
Designed exclusively by Polk, this specially shaped "cone" at the mouth of the bass port directs moving air to eliminate bass-stealing turbulence. No turbulence means no wasted power, which means more efficient bass response.

High-quality tweeter performance
The ring radiator tweeter features several improvements from the version in the earlier LSi line. A slight reshaping of the tweeter's bullet-shaped phase plug allows it to move even farther out of the baffle, while a redesigned diaphragm has made the tweeter even more efficient.

Advanced driver material
The original LSi speakers featured a light, stiff mineral-filled polypropylene cone that was "puffed up" with injected air to form a honeycomb-like structure. The new super cell aerated polypropylene uses larger "puffed cells" to create a cone material that's thicker yet lighter than the original.

Polk LSIM705 Tower (Black)

Superior performance floor-standing tower

Features:
Dynamic Sonic Engine
Dual woofers

High Quality Sound
Fills your world with its wide, dynamic soundstage and its capability to effortlessly achieve truly staggering volume levels. The LSiM705 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 PowerPort® bass venting.

Accurate dialogue
The ring radiator tweeter features several improvements from the version in the earlier LSi line. A slight reshaping of the tweeter's bullet-shaped phase plug allows it to move even farther out of the baffle, while a redesigned diaphragm has made the tweeter even more efficient.

Advanced driver material
The original LSi speakers featured a light, stiff mineral-filled polypropylene cone that was "puffed up" with injected air to form a honeycomb-like structure. The new super cell aerated polypropylene uses larger "puffed cells" to create a cone material that's thicker yet lighter than the original.

Dual woofers
The oval shape helps them produce tight low-frequency music and movie sounds while maintaining a narrow cabinet width. Plus, each woofer has its own PowerPort® — a unique Polk design that positions specially designed "cones" at the mouth of the bass ports to direct moving air to eliminate bass-stealing turbulence.

Polk LSIM706 Centre (Black)

The Big Center Channel for Serious Listeners

The Flagship Center Channel
Polk's LSi M 706c is more than capable of handling the heavy lifting required of a center channel speaker in a high-performance home theater system. It delivers the kind of effortlessly wide, deep soundstage and realistic imaging that puts you in the middle of the on-screen action.

Dynamic Sonic Engine
Made up of a 3-1/4" midrange driver and a 1" ring radiator tweeter in its own acoustically sealed enclosure, this tightly spaced duo acts like a "mini-monitor." The precise alignment of the midrange and tweeter allows them to disperse sound over a wide, uniform area with excellent off-axis response in the critical 200 Hz to 2,000 Hz midrange.

Advanced driver material
The new super cell aerated polypropylene uses larger "puffed cells" to create a cone material that's thicker yet lighter than the original. It's used in both the midrange and woofers, allowing them to move faster and with more efficiency.

PowerPort®
Designed exclusively by Polk, this specially shaped "cone" at the mouth of the bass port directs moving air to eliminate bass-stealing turbulence. No turbulence means no wasted power, which means more efficient bass response.

Polk LSIM707 (Black)

The Ultimate Floorstanding Loudspeaker

Features:
Separate chambers for the midrange and tweeter improve transient response and imaging
Cassini oval subwoofer drivers have more surface area for superior low-frequency response
Klippel motor optimization ensures smooth volume spectrum ends for uniform performance at all volumes
Patented Dynamic Balance® technology eliminates resonance so you hear good sound instead of distortion

Sound That Blankets the Soul
The exclusive Polk Audio Dynamic Sonic Engine allows the LSiM707 to engulf listeners. The unique alignment of internal components allows this speaker within the speaker to disperse sound over a wide area.

Dynamic Sonic Engine 
Exclusive Polk Audio 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.


Beautifully Blended Bass
Cassini oval subwoofer drivers have more surface area than round drivers, dramatically improving their low-frequency response for deep, well-blended bass. The result is sound that seamlessly varies among frequencies for more lifelike reproduction.


VOICE COIL INNOVATION FOR ENHANCED RESPONSE
Innovative overhung voice coil design augments the excursion length for subwoofer drivers, increasing their power-handling capabilities and enhancing bass response. Extended linear motion allows lots of movement in a limited space, eliminating impedance and extending mid- and high-frequency response.

KLIPPEL MOTOR OPTIMIZATION
Laser measurement technology ensures a smooth excursion path at either end of the volume spectrum for uniform performance at high and low volumes.

DYNAMIC BALANCE® TECHNOLOGY
Polk Audio engineers created a way to design out distortion-causing driver and system resonance. That means you hear the sounds created by the artists not the components. 

SUPER CELL AERATED POLYPROPYLENE CONE
Aerated Polypropylene has the ideal balance of superior damping properties and lightweight stiffness for more efficient action with less distortion. The durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for purer sounds note after note.

EXTRA SOLID CABINET ENCLOSURES
High-quality, heavy-duty enclosure construction on the back and bottom, as well as baffles with substantial internal bracing and separate interior cabinetry for each driver eliminate cabinet resonances.
