HF-25T, 25 mm (1") Dome Tweeter

The HF-25T is the new replacement for some of the older models (HF-25V and HF-25S).

It is built with a much higher quality silk diaphragm and the power has increase by 33%. The increased performance actually comes in a smaller package now. The diameter (mounting hole) is only 45 mm.

This is a tweeter for high performance 2, 3 or 4 way sound systems. The suggested operating range is 3 to 17 KHz., and the minimum crossover frequency is 3 KHz.

The neodymium magnet is twice as big, yet the mounting hole remains the same size as the HF-25T (45 mm). This is a tweeter for very high performance 2, 3 or 4 way sound systems.

HF-30B, 30 mm (1.2") Dome Tweeter

This tweeter is the king of all Tweets! It is currently the largest car audio tweeter available. The neodymium magnet is 3 times the size as the one used in the HF-25T.

It produces the highest output of power among all of the tweeters. The mounting hole is 50 mm, so the increased performance you get is only by a 5 mm difference. This tweeter is for very high performance 2, 3 or 4 way sound systems.

The suggested operating range is 2.5 to 20 KHz., and the minimum crossover frequency is 2.3 KHz.
