About Polk Audio LSiM705
High Quality Sound
Fills your world with its wide, dynamic soundstage and its capability to effortlessly achieve truly staggering volume levels. The LSiM705 includes a 5 1/4-inch mid-woofer of lightweight super cell aerated polypropylene for smooth blending with its dual 5x7-inch Cassini oval subwoofer radiators enhanced by Polk's patented PowerPort® bass venting.
Accurate Dialogue
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.

Advanced Driver Material
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.
The LSiM Enclosure
The enclosure is an integral part of the sound design of the new LSiM Series. All LSiM cabinets are made of 1" MDF on the sides, 3/4" MDF on the backs and bottoms, with wide-radius baffles of robust 1 1/4" MDF. Substantial internal bracing, each driver was its own separate non-parallel chamber, increases efficiency and banishes internal resonances and standing waves for high power handling and incredible smoothness. Wide-radius baffles, along with zero-diffraction magnetic grilles, help stabilize imaging for a very wide, well-defined soundstage.
Whether you enjoy music on vinyl, CD, digital files via PC or MP3, or movies on DVD or BluRay,® the performance of the new LSiM Series will transport you. Experience dynamic musical tonality, coherent detail and natural low frequency reproduction, even at lifelike volume levels. Build a home theater or stereo system with new LSiM Series components and experience timbre-matched sonics and immersive spatial ambiance, with realistic accuracy and linearity, even at movie theater volume levels.
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.
