no longer for sale

Here i have a pair of Polk LSiM703 bookself speakers for sale.Theses are great speakers for the money and sound great with music.They have around 80 hours on them and i was running them with a musical fidelity m3 integrated.They are in perfect shape and come with all original packaging.They are in the cherry finish and look great in anyroom.Here is a little info on them. The New Bookshelf for Serious Listening With the performance of the groundbreaking LSiM Series in a smaller, more flexible bookshelf-speaker format, the LSiM703 gives you the best of all worlds. ■Dynamic Sonic Engine (Driver and Tweeter) The heart of the new LSiM Series is this incredible enclosure-within-the-enclosure, the Dynamic Sonic Engine, that houses the mid-range driver and the Ring Radiator Tweeter. Molded in one rigid piece, the DSE enclosure tapers to a "turbine" that reduces back-wave reflections. The DSE combines its two speakers in an aligned, optimized array for wide, uniform dispersion in the critical 200Hz-2kHz midrange, improving transient response; the combination delivers exact timbre-matching, improved high-frequency dispersion and greater horizontal off-axis response ■Enhanced Ring Radiator Tweeter This tweeter was a vital element in the success of the original LSi Series. Yet, that wasn't good enough for the engineers designing the new LSiM Series. They've made some nuanced improvements in the design of this tweeter. First, they reshaped the tweeter's bullet-shaped phase plug, allowing it to move farther out of the baffle, improving dispersion and eliminating horn-loading. Next, they opened up the tweeter's face-plate, then redesigned the tweeter's diaphragm roll to make it more efficient and improve dispersion even more. Finally, they gave their new Ring Radiator Tweeter its own tuned enclosure in the exclusive Dynamic Sonic Engine. This new Ring Radiator boasts higher power handling, extended dynamic range, improved dispersion and extended top-end response. ■Super Cell Aerated Polypropylene Cone Material If the 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, then the Super Cell APP Cone Material is about as perfect as cone material gets. Aerated Polypropylene (APP) is a mineral-filled polypropylene material that's been "puffed up" with injected air to form a honey-comb structure. Our original APP cone approaches the ideal balance of lightweight stiffness with high damping, along with good resistance to moisture, UV and temperature extremes. Next Gen LSiM Series Loudspeakers employ our next gen APP Super Cell. In Super Cell APP, the "puffed cells" are larger, for a thicker cone material that actually has less mass than the original APP material. Super Cell APP has larger cells, for lighter weight and more inherent damping, plus uncompromised stiffness, for unsurpassed transient response and resonance suppression. ■Butyl Rubber Surrounds Durable, soft, injection-molded butyl rubber surrounds are tuned to absorb and suppress unwanted cone resonances. Our new rubber material is impervious to UV, extreme temps and humidity, for a lifetime of smooth, reliable sound. ■Extended Linear Motion Voice Coils Allowing lots of movement in a limited space, ELM Voice Coils power the LSiM mid-range 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.) ■Cast Aluminum Baskets These lightweight, splayed-strut design baskets provide a rigid structure for precise alignment of the speaker's active parts, for flat response and low distortion, with no mechanical resonances or ringing. The open design provides ample venting for unobstructed linear movement. ■Orth Crossovers Proprietary engineering, designed and patented by Polk Audio to maintain a lower order crossover design and increase power handling. Orth Crossovers feature Mylar and Polypropylene Capacitors for sparkling highs and Air Core Inductors for superior transparency. Notch Filters and sophisticated Zobel circuits smooth the impedance curve of the system for more efficiency and better high frequency response. ■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" MDF on the back and bottom, with wide-radius baffles of robust 1 1/4" MDF. Substantial internal bracing, each driver with its own separate non-parallel chamber, increases efficiency and banishes internal resonances and standing waves, for high power handling and incredible smoothness. Wide-radius baffles, along with zero-diffraction magnetic grilles, help stabilize imaging for a very wide, well-defined soundstage. ■Zero-Diffraction Magnetic Grilles Super thin 1mm, zero-diffraction grilles have no measurable effect on the speaker's response. Completely unobtrusive, stylishly sheer, these grilles lock in place magnetically. ■PowerPort Bass Venting Patented Polk Audio technology that uses a specially designed "cone" at the mouth of the bass port to direct moving air as it exits the port. Air moving out of a bass port creates turbulence, which can result in boomy distortion and "port noise," especially at high volume. This distortion can cause bass output losses up to 3dB, wasting lots of amp power. 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. ■Timbre-Matched Series Achieve incredible realism and seamless surround effects when you build a complete LSiM system. All models feature the same components and tuning. ■Dual Metal Gold-Plated 5-Way Binding Posts For the most professional, secure connections. ■Bi-Amp or Bi-Wire Capability For the ultimate in high performance, customizable audio. ■Innovative Hex-Head Floor Spikes Level your towers without having to tip them. ■Rubber Trim Finishes Beautiful furniture-grade fit and finish, with no visible screws. ■Famous Polk Dependability & Durability Like all of our products, the LSiM Series uses only the best materials coupled with the most advanced manufacturing techniques on the planet. All Polk products must pass a battery of the most physically strenuous and exhaustive performance tests in the industry, including drop testing and extreme signal response testing. Polk Audio loudspeakers are built to perform for a lifetime. Paypal Only Ship to confirmed address only Thank for looking
