K-102: three-speaker two-way frequency divider circuit, PTC thermistor protector is used on the frequency divider circuit. Using a 10-inch woofer and powerful voice coil, it can withstand strong power and create a vast stereo sound field and a rich Subwoofer. The unique design of two improved 3-inch tweeters delicately installed on the two oblique side panels of the cabinet makes the coverage of the sound field wider.
