The Wisdom Series LS4i is the latest planar magnetic thin-film technology and represents an uncompromised engineering effort to achieve the ultimate in music and film sound reproduction. With 80” of Planar Line Source, it is ideally suited for installation behind an acoustically transparent screen, as a main speaker or surround.

A single LS4i is capable of reproducing sound pressure levels in excess of 130 dB at 12’. The 80-inch tall line source will provide seamless timbre matching and uniform dynamic expression throughout any listening space.

The LS4i yield breathtaking performance including low distortion, detail, dynamic range, transparency, horizontal dispersion, sound stage imaging and maximum output capability.

Eliminate Floor and Ceiling Reflection

The line source design eliminates floor and ceiling reflection while distributing sound levels uniformly across the width of any room.

Power Over Distance

Line source provides a much better power constituency than point source. This is great benefit when designing entertain net space in large modern open floor living space as well as multi tiers theaters.
