DESC: Kicker Resolution tweeters bring out every last detail in your music. The R25 1" silk dome tweeters deliver exceptional high-frequency focus, without any of the "ear fatigue" that lesser tweeters can cause. Breathtaking!The R25 tweeters handle up to 150 watts RMS, and come equipped with 3,500 Hz passive crossovers (18 dB/octave) to prevent low frequencies from damaging the tweeters. Surface and recessed swivel mounts provide great imaging options.
