Polk Audio LSiM Series Center Channel Speaker with Dynamic Balance® and enhanced, reengineered ring radiator tweeters

Get to know this product.

Build the cinema of your dreams with this high performance flagship center channel speaker designed to hold its own next to the LSiM707 and 705. Two 6 1/2-inch mid-woofer drivers and a dual PowerPort® bass venting system mean that this is a center channel speaker that can effortlessly deliver tremendous volume levels. The 3 1/4-inch midrange and the 1-inch ring radiator tweeter, usually found on speakers costing many times more, help anchor the action to your screen with clear details. The LSiM706c keeps pace, and blends seamlessly, with the front stage output of your LSiM floorstanding loudspeakers.  

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.

Enhanced, Re-Engineered 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.

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.

Klippel 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 Balance®

    Technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.

Our 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.

Durable, Computer-Modeled

    Injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound.

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.

Super-Thin 

    Zero-diffraction grilles lock in place magnetically, and never obscure your sound.

PowerPort 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.
