Polk launches new home speaker line

The new LSiM series from Polk Audio encompasses a full range of tower, bookshelf, centre and surround channel models. Open, transparent, three-dimensional sound and uniformly wide dispersion were among the objectives for the new product range, which is due to be made available in the first quarter of next year.

The new flagship Polk lineup is spearheaded by two four-way floor-standing tower models, the LSiM 707 (SRP: $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 centre channel models are offered in the flagship LSiM series. The larger LSiM 706c (SRP: $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 (SRP: $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.

Mark Suskind, v-p of Product Line Management, told IE Residential: “There are some great reasons for a residential specialist to recommend products from Polk Audio’s new LSiM Series. One being for the customer lusting for the true high end, high performance Home Theater experience and has no problem with a dedicated area in the home to make this dream a reality. Another is that the LSiM Floor standing and bookshelf speakers are designed to satisfy even the most discriminating audiophile that still values freestanding loudspeakers for two-channel critical listening.”
