Each pair combines a lightweight 1\" polyimide dome, a 4-ohm voice coil, and multiple mounting options so installers can tune the positioning and match cabin acoustics. Sensitivity of 102 dB at 1 W\/1 m helps them sing with minimal amplifier power, while a frequency range from 5 kHz to 20 kHz targets the upper harmonics that bring vocals and cymbals to life.\u003c\/p\u003e\n\n\u003ch3\u003eHow do the TW18 tweeters improve clarity in everyday listening?\u003c\/h3\u003e\n\u003cp\u003eThese tweeters reproduce upper-frequency details that larger speakers may miss, reducing muddiness and improving the sense of air around instruments and voices.
