Polk Audio LSiM 707 Loudspeaker (Mt. Vernon Cherry, Each)

The ultimate statement of Polk’s mission, the LSiM707 is like no other loudspeaker in its price range. Featuring exclusive state-of-the-art technologies, proprietary patents, and designed in-house from the ground up, this is pure high performance audio of a completely different stripe. Experience realistic, transparent midrange reproduction with a 3 1/4-inch midrange driver of lightweight super cell aerated polypropylene. Pinpoint detail is revealed by a 1-inch ring radiator tweeter, a feature usually found on speakers costing much more. The LSiM707 effortlessly achieves the deepest bass with dual 6×9-inch Cassini oval subwoofer radiators and Polk’s patented PowerPort bass venting, which eliminates performance-robbing turbulence at the mouth of the bass port. Engineered into a sculpted, state-of-the-art enclosure and finished like a beautiful piece of furniture, there is simply nothing like the LSiM707.
Polk’s exclusive dynamic sonic engine design optimizes the midrange driver and the ring radiator tweeter in separate interior chambers for improved transient response, superior imaging and greater horizontal off-axis response.
Enhanced, re-engineered ring radiator tweeters extend top-end response for incredible details and realistic imaging.
Extended Linear Motion voice coil design helps extend mid- and high-frequency response.
Klippel motor optimization uses laser measurement technology to ensure a consistent excursion path at either end of the driver’s travel for uniform performance at both low and high volumes.
Exclusive, patented Roth crossovers increase lower-order power handling and smooth the impedance curve, for more efficiency and better high frequency response.
