Favorites tweeter 2023

Your choice between these tweeter types will depend on the sonic characteristics you desire, your budget, and the specific design and requirements of your horn system. It's important to match the tweeter with the rest of your favorite car system components and ensure that the crossover is properly designed to achieve the desired frequency response and dispersion.
Audax TW025A28 if system sensitivity is around 93 dB / 2.83V.

The Selenium ST200 is really nice for higher sensitivity and xover above 5k. Its also only $30.

Faital FD371 is my favorite high end option for lower xover around 3.5k and higher sensitivity.

The Morel CAT378 is also nice with only one 3.9 uf cap.
