L8i Loudspeaker
The L8i benefits from the same core technologies and design elements of the Sage Series L75i packaged in a more compact and flexible form. It combines application specific, state-of-the-art transducer elements in a way that takes full advantage of their inherent performance benefits.

The Insight Series™ brings key core technologies and performance characteristics of the award-winning Sage Series® to more accessible price points. Each Insight Series model incorporates both newly developed planar magnetic thin-film drivers and moving coil woofers, all proprietary and designed by Wisdom Audio. Unlike the fully active Sage Series, the Insight Series utilizes precision passive crossover networks making it possible to drive each speaker with a single amplifier channel.

The L8i employs a 48-inch planar magnetic line source to reproduce everything above 550 Hz and eight proprietary woofers for the bass. The L8i’s 48-inch tall line source driver complement allows for high resolution, low distortion and superior dynamic range. The result is highly detailed, dynamically accurate, genuinely effortless performance at any volume level. We encourage you to learn more about the advantages of our proprietary planar magnetic drivers here.

For installations and budgets where the use of L8i line sources is possible, there are real-world advantages. Since true line sources, not to be confused with stacked, point source arrays trying to be line sources, effectively eliminate floor and ceiling reflections, they are especially valuable for large rooms or those with architectural challenges including cathedral or coffered ceilings, hard-surfaced floors, etc. But their singular benefit is heard in any room: you hear more of the speaker and less of the room. Everything is significantly clearer.

The true line source behavior of the L8i also exhibits less propagation loss than any conventional loudspeaker, resulting in a vastly enlarged “sweet spot” that is particularly beneficial in any situation with a large seating area. Whether in a media room with a casual seating arrangement or dedicated home theaters with multiple rows of seating, everyone in the audience is treated to “money seat” performance. Learn more about the advantages of line sources here.

Because the L8i is a line source, it requires installation behind an acoustically transparent screen for use as a center channel and is not able to be used horizontally either below or above the screen. In such installations (as in professional cinemas), having the center channel information delivered from behind the screen lends a sense of coherence and vocal localization that provides an even more engaging experience for the listener. For installations that include a flat panel display and therefore a horizontally positioned center channel, L8i left and right channels can be paired with either the P6i or P4i point source center channel.

In the classic manner of trickle down technology, Wisdom Audio is proud to offer an extension of our essential core technology with the Insight Series. Maintaining some key benefits of our Sage Series, the L8i and its three siblings are ideally suited for the listener that demands both superior performance and a less complex installation. Comparable only to the more sophisticated, award-winning Sage Series, these amazing loudspeakers continue the evolution of Wisdom Audio’s performance-driven architectural solutions at the pinnacle of the category. Whether the Insight models are used for an entire system or mixed with Sage models, the performance will always provide a compelling and rewarding listening experience.
