49ST4TW 2-Pack + ROCK ANYWHERE

This bundle pairs a set of Kicker ST4TW bullet tweeters for your car's audio system with a Rockville ROCK ANYWHERE portable Bluetooth speaker for everywhere else. The tweeters use a horn-loaded aluminum diaphragm for PA-style output and vocal clarity that stays audible over high-output bass, with front or rear mount options and a built-in 6dB crossover that simplifies installation. Rated at 108dB sensitivity and 15-50W RMS recommended power, they add real high-frequency detail to a system without demanding a large amplifier channel. The ROCK ANYWHERE speaker covers you once you are out of the car: it is fully IPX7 waterproof and submergible, puts out 20W of peak power with two passive radiators for real bass in a compact body, and pairs over Bluetooth 4.1 with a 40-foot range. Two units can link together over TWS for true left and right stereo sound, and a 2000mAh battery runs up to 30 hours at moderate volume. Together, this bundle covers both ends of a car audio upgrade: sharper, clearer highs inside the vehicle, and a rugged, portable speaker for the pool, shower, or campsite once you step outside it.
