Polk Audio LSiM Series Speakers
Newly Engineered, Flagship Loudspeaker Line
Polk Audio® announced a new top of the line home audio speaker lineup that brings the company's legendary sonics to their highest pinnacle yet. The new LSiM series utilizes Polk's most advanced engineering to date, achieving remarkable high-end performance that makes a true audiophile listening experience accessible to music lovers everywhere.
The new Polk LSiM series encompasses a full range of tower, bookshelf, center and surround channel models, each of which is designed with the finest materials and Polk's most advanced acoustic engineering. The performance objectives for the series were set with an exceptionally high bar — open, transparent, three-dimensional sound, with accurate tonal and temporal response at all frequencies; extended dynamics; uniformly wide dispersion; deep, tight, integrated bass; and compatibility with a broad range of past, present and future electronics. Each of these difficult sonic objectives has been achieved in the new LSiM series.
The new flagship Polk lineup is spearheaded by two 4-way floor-standing tower models, the LSiM 707 ($1,999 each) and LSiM 705 ($1,499 each). Each features state-of-the-art transducers built with Polk's Dynamic Balance® design technology, which combines the latest in composite materials and computer-assisted geometry to create drivers with extraordinarily low distortions and artifacts. Both towers sport a stunning array of these high performance drivers, highlighted by Polk's Dynamic Sonic Engine enclosure, a single molded component that carries both a Polk proprietary 3.25″ Extended Linear Motion (ELM) mid-range driver and a 1.0″ Advance Isotropic ring radiator (AIR) tweeter.
Combining these transducers in a single optimized array produces an uncommonly wide and uniform dispersion pattern. The top-of-the-line LSiM 707 complements this array with a 6.5″ ELM mid-woofer driver and dual 6×9″ ELM subwoofers featuring Polk's PowerPort®, which maximizes low-bass energy ordinarily lost as air turbulence in the enclosure. The smaller LSiM 705 features the identical Dynamic Sonic Engine for high frequencies and midrange, along with Polk designed ELM 5.25″ mid-woofer and dual 5×7″ ELM subwoofers. A bookshelf-sized version of the towers, the LSiM 703, utilizes the same technologies as the towers, minus the internal subwoofer drivers.
Two center channel models are offered in the flagship LSiM series. The larger LSiM 706c ($1,099 each) features the same AIR ring tweeter and E:M 3.5″ mid-bass driver that characterizes the Dynamic Sonic Engine of the larger tower models, flanked by two ELM 6.5″ mid-bass drivers with a rear port design. A smaller center channel model, the LSiM 704c ($699 each) features the same layout, only with ELM 5.25″ mid-bass drivers. The LSiM 702f/x surround model ($749 each) completes the series for a multichannel setup, offering a ELM 3.25' mid-range, 2 x 1.0″ AIR ring radiator tweeters and a ELM 6.5″ mid-woofer driver. All the speakers have been timbre matched for a perfectly blended and balanced acoustic environment.
The Polk LSiM series features Polk's most advanced material engineering, with Super Cell Aerated polypropylene cones that reduce mass and its resulting distortions. Driver baskets are built from cast aluminum frames that provide superior rigidity and exceptionally flat frequency response. Butyl rubber surrounds ensure outstanding linearity through many years of trouble free performance. Finishing touches include magnetic, non-diffracting grills, easy-leveling floor spikes and rubber trims around the driver baskets that create a cosmetically clean fit and finish.

“The LSi line has been Polk's flagship selection for almost a decade, but in light of current technological possibilities, we felt it was time for a re-visit. The result is not so much an evolution of the current series as it is a re-engineering of the qualities that have made LSi the best in its class.”
