The LSi Legacy

First introduced in 2001, LSi represented Polk’s expression of a true high-performance loudspeaker that was also reasonably priced. LSi was created for the serious listener, those who really enjoy music and who enjoy intently listen- ing to their audio system. LSi delivered a flatter frequency response with lower distortion and revealed more detail than comparably priced speakers. The series was also touted in the press for its tonal accuracy. LSi imaged very well, thanks in part to the quality of the tweeter

and the wide dispersion of the small midbass drivers. The series’ performance has made LSi Polk’s flagship product for almost a decade. But after a decade, it was time to revisit LSi. The result is not so much an evolution of the current series as it is a re-engineering of the qualities that have made LSi a great series.

LSiM specifications

Polk Audio has long been synonymous with quality sound reproduction, and the LSiM series stands as a testament to this reputation. Known for their innovative engineering and exceptional sound quality, the LSiM speakers are designed to cater to audiophiles and casual listeners alike, delivering a rich and dynamic audio experience.

One of the main features of the LSiM series is its use of advanced materials and technologies, which include the use of Dynamic Balance drivers. This unique driver technology enables the speakers to minimize distortion while maximizing transparency and sound detail. The LSiM speakers are equipped with a 1-inch ring radiator tweeter and a specially designed 5.25-inch midrange driver. This combination ensures that high frequencies are crisp and clear, while midrange sounds are natural and warm, providing a well-balanced audio performance across genres.

Another standout characteristic of the LSiM series is its construction quality. The cabinets are meticulously engineered using high-quality materials that help reduce resonance and ensure durability. The curved design not only contributes to aesthetics but also aids in the dispersion of sound, resulting in a wider sweet spot for listeners. Each speaker comes with a rear-firing bass port that enhances low-frequency response, allowing for deeper bass without compromising clarity.

Polk Audio has also integrated its patented Power Port technology in the LSiM speakers. This technology effectively extends the low-end frequency response while eliminating turbulence and distortion caused by traditional port designs. The result is an impressive bass output that remains tight and controlled, perfect for both music and home theater applications.

The LSiM series offers versatility in terms of speaker configuration. Available in various models, including floor-standing, bookshelf, and center channel options, these speakers can be mixed and matched to create a custom sound system that fits any space. Their aesthetic appeal is further enhanced by a modern and elegant finish, making them a stylish addition to any room.

In conclusion, the Polk Audio LSiM series combines advanced technologies with superior craftsmanship to deliver an unparalleled listening experience. Whether for a high-end home theater setup or everyday music enjoyment, the LSiM speakers promise to provide an immersive soundstage and exceptional audio fidelity, making them a remarkable choice for anyone seeking quality sound in their home.
