KM308G2 Card-Style Speaker System
The KM308G2 is a compact speaker system specifically designed for KTV applications, ideal for sound reinforcement in small KTV rooms as well as home entertainment systems. It features a two-way full-range speaker system comprised of one long-stroke 8-inch woofer and two 3-inch low-distortion paper-cone tweeters. The meticulously engineered high-order crossover minimizes frequency band overlap while optimizing vocal reproduction. The 8-inch driver boasts a long-fiber paper cone and a foam surround, delivering excellent suspension linearity and ensuring it can handle high-power outputs without distortion. Meanwhile, the tweeter incorporates an innovative semi-open acoustic phase plug design—inspired by JBL’s legendary classic models—providing wide, even sound coverage with exceptional clarity and detail. With its rich, smooth sound quality, the KM308G2 perfectly meets the demands of high-fidelity music playback. It can also be paired with a subwoofer to achieve outstanding low-frequency response, making it versatile enough for use in a variety of settings.
