Dayton Audio's ST602-4 tweeter was designed to articulate and reinforce the high frequency output of any professional loudspeaker. With an excellent price/performance ratio, this model can be an excellent choice for many audio designs. In addition, its wide frequency range allows it to even compete with many midrange speakers, while enjoying a nice extension in the treble, adding air and clarity to any sound system. The ST602-4 also has a high sensitivity of 106dB, making it suitable for use with even the most sensitive speakers.
