There’s no doubt that bookshelf loudspeakers offer greater placement flexibility than floorstanding loudspeakers but usually with a trade-off in performance.
Not so with the LSiM 703 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 LSiM 703 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 LSiM Series in a smaller, flexible bookshelf speaker format, the LSiM 703 gives you the best of all worlds.
- Polk’s exclusive dynamic sonic engine design optimises 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.
- Our innovative overhung voice coil design augments the excursion length for subwoofer drivers, increasing their power-handling capabilities and enhancing bass response.
- Extended Linear Motion voice coil design allows lots of movement in a limited space, eliminating impedance and extending mid- and high-frequency response.
