1' Tweeter In F1320 Monitor Vs. 3' In F1220 Model

The difference between a tweeter and the other two types of drivers is mainly size-related. A woofer is the biggest type of driver, and it's meant to create low-frequency sounds. Meanwhile, tweeters are a lot smaller and they make the highest frequency sounds. Not surprisingly, mid-range speakers cover the middle part of the spectrum between the woofers and the tweeters. The size of the tweeter dictates the frequency because to make higher frequency waves, the diaphragm has to vibrate faster. It's too hard for a large driver to vibrate fast enough to create the sounds of a tweeter. Often, a stereo will break down its electrical signals into different frequencies, and each of the three types of driver will handle the part assigned to its capabilities. Many times, the drivers are all housed within the same enclosure. The f1320 has a proprietary 1.75'' titanium-diaphragm compression driver for exceptional high-frequency reproduction. The f1220 has a 3" high-frequency compression driver. My understanding is the smaller & composition of the tweeter provides the ability to reproduce the higher frequency's.
