About Polk Audio LSiM 705 Superior Floorstanding Tower

From the Manufacturer The ultimate statement of Polk's mission, the LSiM707 is like no other loudspeaker in its price range. Experience realistic, transparent midrange reproduction, pinpoint detail and the deepest bass with the LSiM 707. Engineered into a sculpted, state-of-the-art enclosure and finished like a beautiful piece of furniture, there is simply nothing like the LSiM 707.key featuresPolk'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.Cassini oval subwoofer, 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. take a look at this product technology Dynamic Sonic Engine This is a molded enclosure within the cabinet that houses the super-accurate ring radiator tweeter and the extended motion midrange driver in their own separate, tuned compartments. This aligned, optimized array contributes to wide, uniform dispersion in the critical 200Hz - 2kHz range. The dynamic sonic engine, in turn, lives in a separate, rigidly braced enclosure-within-the-enclosure. This separation and specialized tuning measurably reduces performance-robbing back wave reflections. The result is astonishing detail and realistic imaging, with improved transient response, exact timbre-matching, and greater horizontal off-axis response.Enhanced Ring Radiator Tweeter Our engineers took the ring radiator tweeter, usually seen in only the most exotic speakers, and found way to improve it. They reshaped the tweeter's bullet-shaped phase plug to eliminate horn-loading and improve dispersion. Redesigning the tweeter faceplate and the diaphragm added efficiency. Finally, they gave their new ring radiator tweeter its own tuned enclosure within the dynamic sonic engine. This enhanced ring radiator boasts higher power handling, extended dynamic range, better dispersion and extended top-end responseSuper Cell Aerated Polypropylene Cone MaterialThe perfect cone material is lightweight (for faster, more efficient action) and stiff (for less distortion-causing flex), with enough internal damping to suppress and offset any limitations of its lightweight stiffness and our super cell aerated polypropylene cone material is about as perfect as it gets. It's the ideal balance of lightweight stiffness with high damping, along with good resistance to moisture, UV and temperature extremes. Our drivers are fast, linear and nearly resonance free.Extended Linear Motion (ELM) Voice Coils Allowing lots of movement in a limited space, ELM voice coils power the LSiM midrange and mid-woofer drivers to extend their higher frequency response with much less impedance. (LSiM subwoofers use overhung coils, which allow the larger excursions and greater power handling necessary for big subwoofer performance.)The LSiM Enclosure The enclosure is an integral part of the sound design of the new LSiM Series. All LSiM cabinets are made of 1.0" MDF on the sides, 3/4" on the back and bottom, and wide radius baffles of robust 1 1/4-inch MDF. Substantial internal cabinetry, each driver with its own separate asymmetrical chamber, increases efficiency and banishes internal resonances and standing waves, for high power handling and incredible smoothness. The narrow baffle with its wide radiuses enhances the imaging for a very wide, deep and well-defined soundstage. why you should consider this produc
