The Exc!te Award, August 2012
The Insight Series received Custom Retailer magazine’s Exc!te Award for Excellence in Custom Installed Technologies and Electronics.
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, and use of the SC-1 System Controller optional.
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.

Environmental Testing Data View»
Designing reliable audio products involves the exhaustive and thorough evaluation of every component part used in their construction. Every material type, adhesive, and finish coating must be chosen carefully.
In order to insure the highest degree of reliability of our products when exposed to the most extreme environmental conditions, Wisdom Audio has submitted all key components to severe environmental testing. As many of the transducers are new to a large part of the audio market, the question of reliability is raised from time to time, especially as it relates to marine applications.
The components were exposed to the following conditions in a variety of test chambers by Environmental Associates of Chatsworth, California.
- Exposure to 85 degrees Celsius at 85% relative humidity for a period of ten days.
- Temperature cycling from minus 40 degrees Celsius to plus 105 degrees Celsius with a two hour dwell time at each extreme for a period of five days.
- Salt fog exposure at 95 degrees F with a 5% mist of salt solution for 48 hours.
The test results were very interesting and useful, allowing us to make minor modifications to what otherwise endured these extremes beyond even our own expectations.
