Luxurious sound from Polk’s gorgeous, flagship floor-standing speaker

Immerse yourself in smooth, high-end sound that envelops and caresses you thanks to Polk’s LSi M 707. Building upon the widely acclaimed LSi family of speakers, the new LSi M series incorporates the latest developments in speaker technology, fitted into a newly designed enclosure that’s beautifully sculpted and luxuriously finished. You’ll hear a wide, deep soundstage with realistic imaging fleshed out in pinpoint detail, and anchored by effortlessly deep bass. It’ll faithfully reproduce your most demanding audio sources from top to bottom, without any help from a separate subwoofer. It makes an excellent pair in a stereo music setup or becomes the shining star in a knock-out home theater system.




Polk’s Dynamic Sonic Engine: The speaker within a speaker

An exploded view of the Dynamic Sonic Engine with the tweeter and midrange at the top of the speaker.

The heart of the LSi M 707 is Polk’s Dynamic Sonic Engine. Made up of a 3-1/4" midrange driver and a 1" ring radiator tweeter in its own acoustically sealed enclosure, this tightly spaced duo acts like a "mini-monitor." The precise alignment of the midrange and tweeter allows them to disperse sound over a wide, uniform area with excellent off-axis response in the critical 200 Hz to 2,000 Hz midrange.

The ring radiator tweeter features several improvements from the version in the earlier LSi line. A slight reshaping of the tweeter’s bullet-shaped phase plug allows it to move even farther out of the baffle, while a redesigned diaphragm has made the tweeter even more efficient. It even has its own tuned enclosure within the Dynamic Sonic Engine. These changes result in higher power handling, extended dynamic range, improved dispersion, and extended high-frequency response — all the way up to 30,000 Hz!

Advanced driver material for even more realistic sound

The original LSi speakers featured a light, stiff mineral-filled polypropylene cone that was "puffed up" with injected air to form a honeycomb-like structure. The new super cell aerated polypropylene uses larger "puffed cells" to create a cone material that’s thicker yet lighter than the original. It’s used in both the midrange and midbass drivers, as well as both woofers, allowing them to move faster and with more efficiency.

Dual woofers deliver smooth, effortless bass

Low on the ’707’s front baffle you’ll notice dual 6" x 9" woofers. The oval shape helps them produce tight low-frequency music and movie sounds while maintaining a narrow cabinet width. Plus, each woofer has its own PowerPort® — a unique Polk design that positions specially designed "cones" at the mouth of the bass ports to direct moving air to eliminate bass-stealing turbulence. No turbulence means no wasted power, which means more efficient bass response.
