The KB6000 is a full-range, high-efficiency speaker system truly suitable for indoor and outdoor use, providing an eight-ohm load and ready to be driven by home stereo receivers. That legendary Kicker sound is now made to rock from a backyard deck, under the eaves or near the pool, and the Kicker Full-Range Indoor Outdoor Speakers still provides great sound on a boat, off-road vehicle or RV. The dual-enclosure system features bold 6-1/2-inch Kicker woofers and compression-loaded horn tweeters firing a favorite music mix. The woofers utilize precisely tuned polypropylene cones and rugged Santoprene surrounds. The Kicker Full-Range Indoor Outdoor Speakers acoustically blends with a 12dB/octave low-pass crossover with impedance compensation to nail that signature sound.
