Polk LSiM707 Floor Standing Loudspeaker

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.
  • Enhanced, reengineered 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.
  • 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.
  • 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 effecient sound delivery.
