It produces the kind of wide, deep soundstage and life-sized imaging that puts you in the middle of the action on your TV's screen. You'll hear conversations between your favorite movie or TV show characters with pinpoint detail, complemented by special effects that cover the range from smooth bass to delicate highs. Building upon the widely acclaimed LSi family of speakers, the LSi M series incorporates the latest developments in speaker technology, fitted into a newly designed enclosure that's beautifully sculpted and luxuriously finished.\u003c\/p\u003e\n\u003ch4\u003ePolk's Dynamic Sonic Engine: The speaker within a speaker\u003c\/h4\u003e\n\u003cp\u003eLike all LSi M models, the '704c center channel speaker uses 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 an excellent off-axis response in the critical 200 Hz to 2,000 Hz midrange.\u003c\/p\u003e\n\u003ch4\u003eHigh-quality tweeter performance\u003c\/h4\u003e\n\u003cp\u003eThe 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!\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cimg class=\"fltlft\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0806\/9500\/1374\/files\/h107LS704CM-O.jpeg\" alt=\"Grille off\"\u003e\u003c\/p\u003e\n\u003ch4\u003eAdvanced driver material for even more realistic sound\u003c\/h4\u003e\n\u003cp\u003eThe 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 woofers, allowing them to move faster and with more efficiency. This speaker also uses proprietary Orth Crossovers to send the right frequencies to the right drivers, making it extremely efficient and easier for your receiver or amplifier to drive.\u003c\/p\u003e\n\u003ch4\u003ePowerPort® technology for smooth, deep bass\u003c\/h4\u003e\n\u003cp\u003eLike all LSi M speakers, the dual 5-1\/4\" woofers each have their own PowerPort.

Each driver has its own separate, non-parallel chamber to increase efficiency and eliminate internal resonances and standing waves. The magnetic grille easily snaps on and off, and it measures less than 1mm thick, so it won't interfere with the sound.

The center channel houses a 1\" (diameter) Dynamic Balance Enhanced Ring Radiator Tweeter, a 3.25\" (diameter) Dynamic Balance Super Cell Aerated Polypropylene cone midrange driver, \u0026amp; two 5.25\" (diameter) Dynamic Balance Super Cell Aerated Polypropylene cone midbass woofers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEnhanced Ring Radiator Tweeter: \u003c\/strong\u003eThe ring radiator tweeter was a vital element in the success of Polk Audio's original LSi Series. Polk Audio engineers have made some nuanced improvements in the design of this tweeter. First, they reshaped the tweeter's bullet-shaped phase plug, allowing it to move farther out of the baffle, improving dispersion and eliminating horn-loading. Next, they opened up the tweeter's face-plate, then redesigned the tweeter's diaphragm roll to make it more efficient and improve dispersion even more. Finally, they gave the new ring radiator tweeter its own tuned enclosure (Dynamic Sonic Engine). This new ring radiator tweeter boasts higher power handling, extended dynamic range, improved dispersion, and extended top-end response.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuperCell Aerated Polypropylene (APP) Cone Woofer:\u003c\/strong\u003e If the perfect cone material is lightweight (for faster, more efficient action) and stiff (for less distortion-causing flex), with enough internal damping to suppress and offset any limitations of its lightweight stiffness, then the SuperCell APP Cone Material is about as perfect as cone material gets. Aerated Polypropylene (APP) is a mineral-filled polypropylene material that's been \"puffed up\" with injected air to form a honeycomb structure. Polk Audio's original APP cone approached the ideal balance of lightweight stiffness with high damping, along with good resistance to moisture, UV, and temperature extremes. Next-generation LSiM series loudspeakers employ Polk Audio's next generation of APP SuperCell. In the Super Cell APP, the \"puffed cells\" are larger, for a thicker cone material that actually has less mass than the original APP material. SuperCell APP has larger cells, for lighter weight and more inherent damping, plus uncompromised stiffness, for unsurpassed transient response and resonance suppression.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eButyl Rubber Surrounds: \u003c\/strong\u003eDurable, soft, injection-molded butyl rubber surrounds are tuned to absorb and suppress unwanted cone resonances.

Air moving out of a bass port creates turbulence, which can result in boomy distortion \u0026amp; \"port noise\", especially at high volume. This distortion can cause bass output losses up to 3dB, wasting lots of amp power. To eliminate bass-stealing turbulence at the mouth of the port, Polk Audio engineers designed the PowerPort. Its unique shape promotes \"laminar\" airflow even in short tube ports by mimicking the properties of longer, flared port openings.
