Bullet Tweeter Frequency Spectrum

Some one asked what is the frequency spectrum for Bullet Tweeter. From the spec, it is from 1.8K to 30K.

* Similar to KSN1142A * Power handling: 100 watts RMS. * Frequency response: 1800-30000 Hz * SPL: 92 dB 1W/1m * Mounts to any 1-3/8", 18TPI horn *

But from the Frequency Spectrum, you can see clearly that 1.8KHz to 30KHz is where the SPL > 90dB.

For SPL > 80dB, the min frequency actually start at 800Hz.
Some study said that Swiftlet sound start as low as 1KHz. So, it is important to get a good tweeters that can cover the whole frequency range.

The Bullet Tweeter is used in Bullet Bazooka and Magic Tweeter.
