Product Description

There’s no doubt that bookshelf loudspeakers offer greater placement flexibility than floor standing loudspeakers but usually with a trade off in performance. Not so with the Lsim703 bookshelf loudspeakers. You’ll be delightfully surprised to hear the kind of performance that befits our flagship loudspeaker line. With a 6 1/2 inch Mid Woofer, 3 1/4 inch midrange, both of lightweight super cell Aerated polypropylene, combined with the enhanced deep musical bass response of Polk’s patented power port bass Venting system, The Lsim703 delivers a wide, deep, dynamic soundstage. The addition of the proprietary 1 inch ring radiator tweeter adds Pinpoint detail for realistic imaging. With the performance of the groundbreaking slim Series in a smaller, flexible bookshelf speaker format, The Lsim703 gives you the best of all worlds.

key 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.
  • Our innovative overhung voice coil design augments the excursion length for subwoofers, increasing their power-handling capabilities and enhancing bass response.
  • Extended linear motion voice coil design allows lots of movement in a limited space, reducing 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.
  • Polk’s proprietary, patented Dynamic Balance® technology designs out distortion-causing driver and system resonances, so you only hear the good sounds.
  • 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.

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 response

Klippel Optimized Dynamic Balance® Transducers
All transducers are developed using our proprietary Dynamic Balance technology to reduce or eliminate unwanted material and interface resonance that color the sound. Klippel measurement systems are employed during development to ensure the speaker will deliver life-like highly detailed playback at both low and high volumes levels.

Super Cell Aerated Polypropylene Cone Material
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 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.

*To ensure a valid warranty, Polk loudspeakers must be purchased through an Authorized Polk home or car loudspeaker Dealer (such as Amazon.com). (If you’re not sure a dealer is “authorized,” call Polk at 1-800-377-7655, and ask us.) The warranty is not transferrable, that means it applies only to the original purchaser. If you purchase your speakers from a private individual, that product is considered “used” and has NO factory warranty, no matter what the seller implies. The warranty is VOID if the serial number of the speaker has been removed or defaced. If you have any questions about your warranty coverage, or you think you need service, call Polk Customer Service at 1-800-377-7655. We’re here to help you get the most from your new speakers!
