P4i Loudspeaker
The Insight Series P4i builds upon the foundation of clarity, detail and dynamic expression of its smaller P2i sibling. For higher listening levels or rooms that require higher output than the P2i can accommodate, the larger P4i can pick up where the smaller P2i leaves off.

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 P4i uses four of the same proprietary woofers found in the larger Insight Series models, and two more than the P2i, therefore allowing for the higher output level beyond its smaller sibling's capabilities. Its amazing planar magnetic tweeter is responsible for this series’ characteristic transparency, detail and instantaneous dynamics, handles the midrange and high frequencies, and extends all the way down to 650 Hz. This incredible PMD, shared in common with the smaller P2i, easily outperforms a conventional 1-inch dome tweeter in output level and dynamics, while handling almost two additional octaves of the midrange, simply not possible with a traditional dome tweeter design. The result is excellent, uniform horizontal dispersion throughout its operating range. We encourage you to learn more about the advantages of our proprietary planar magnetic drivers here.

The P4i is a point source loudspeaker like the vast majority of loudspeakers available in the world. Point sources radiate their sonic energy outward in an expanding sphere, as though from a point in space. The P4i can be used as a center channel, either horizontally to accompany a flat panel display, or vertically behind an acoustically transparent screen, as the perfect complement to a pair of P4i (or P6i) left and right channels.

Slim and elegant in design, the narrow aspect P4i becomes one with the wall, via its paintable grill, blending nicely into a variety of décors where traditional loudspeakers might otherwise intrude excessively on the room’s appearance.

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 P4i 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.
