Wisdom Audio introduces their new modular line source loudspeaker systems, the Wisdom Series LS4 and LS3, designed by a team directed by David Graebener of Wisdom Audio and featuring an architectural industrial design by Ashcraft Design of Los Angeles.

Featuring Wisdom's proprietary wideband planar magnetic line source technologies, the Wisdom Series LS4 and LS3 are comprised of newly designed individual modules, 20" in height, each incorporating two planar magnetic midrange drivers flanking a planar magnetic high frequency driver in a vertical line source configuration. The LS4 combination features four modules, with a total vertical line source height of 80". The LS3 includes three modules with a combined vertical line source height of 60".

Unlike conventional speaker systems that typically incorporate various combinations of cone and dome drive units, the Wisdom Series LS3 and LS4 models feature their newest planar magnetic line source drivers. A two-way system, each module features dual high efficiency and high output upper bass/lower midrange planar magnetic drivers that handle frequencies reportedly from 80 Hz to 750 Hz. From there, the high efficiency and high output upper midrange/tweeter planar magnetic driver covers the rest of the range, with flat response that Wisdom claims extends beyond 20 kHz.

Internal wiring features cabling sourced from Transparent Audio, the industry's most respected audiophile cable manufacturer. The depth of each on-wall enclosure is 12 inches.

Unlike conventional speaker drivers which are magnetized after assembly, the planar magnetic drivers used in the new Wisdom Series LS4 and LS3 models incorporate magnet assemblies that are pre-energized prior the driver's final assembly. According to Wisdom, the LS4 incorporates no fewer than 1,656 magnets, equal to 392 linear feet. The lower range driver uses ceramic magnets, whilst the upper range driver incorporates neodymium magnets.

The Wisdom Series LS4 and LS3 are designed to optimally mate with Wisdom Audio's STS Regenerative Transmission Line® subwoofer, which features the same combination of ultra-high efficiency and dynamic range.

The Wisdom Series LS4 and LS3 systems will be unveiled at the International Consumer Electronics Show in January 2011, with initial deliveries beginning in February. The North American MSRP will be $40,000 each for the Wisdom Series LS4, and $30,000 each for the Wisdom Series LS3.
