Polk LSIM703 Bookshelf Speakers (Pair)

R 30,990.00Dynamic Balance Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response, & low distortion. Dynamic Balance 3-Way Driver System The Polk Audio LSiM series bookshelf loudspeaker employs a 3-way driver system for crisp, detailed highs; natural, lifelike midrange; and accurate, dynamic midbass. 3-Way Driver System PowerPort Bass Venting To eliminate bass-stealing turbulence at the mouth of the port, Polk Audio engineers designed the PowerPort. It's unique shape promotes "laminar" airflow even in short tube ports by mimicking the properties of longer, flared port openings. No turbulence means no wasted power, which means more efficient bass response. PowerPort Bass Venting Polk Audio LSiM703 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. • Polk Audio 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 Polk Audio engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds. • Polk Audiosuper 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 on the back and bottom and 1 1/4" 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. • 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 systems. • Dual gold-plated, professional-style 5-way binding posts, for the most secure connection options. • Dual binding posts allow bi-amp or bi-wire connection
