There's no doubt that bookshelf loudspeakers offer greater placement flexibility than floor standing loudspeakers but usually with a trade-off in performance. Not so with the LSiM703 bookshelf loudspeakers. You'll be delightfully surprised to hear the kind of performance that befits our flagship loudspeaker line. With a 6 1/2-inch mid-woofer, 3 1/4-inch midrange, both of lightweight super cell aerated polypropylene, combined with the enhanced deep musical bass response of Polk's patented PowerPort bass venting system, the LSiM703 delivers a wide, deep, dynamic soundstage. The addition of the proprietary 1-inch ring radiator tweeter adds pinpoint detail for realistic imaging. With the performance of the groundbreaking Slim Series in a smaller, flexible bookshelf speaker format, the LSiM703 gives you the best of all worlds.
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, reengineered ring radiator tweeters extend top-end response for incredible details and realistic imaging.
Extended Linear Motion voice coil design allows lots of movement in a limited space, eliminating impedance and extending mid- and high-frequency response.
Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
