Can you feel speaker tweeters vibrate? How to tell they are working?

I recently bought creative gigaworks t20 series 2.0 speakers for $50 refurb at amazon. They look and sound good but i notice that if i hold my finer to the tweeter domes, i cannot feel any vibration even at loud volumes, the mid range drivers and the woofer port has plenty of vibe. is there a way to test they are working correctly?

Since they are high frequency, you might not feel them move... or even hear them if it is outside of your audible range. If you want to test for sure, you will need to isolate a high frequency and push it through the speaker. A quick search identified: http://www.world-voices.com/softw...htone.html

This will allow you to generate a tone in the high freq. range. If you can't hear it, you could use a mic to pick up the signal to see what you get... using Windows sound recorder or something else that allows you to view the wave form would work well. Holding the mic directly up to the tweeter will help you know whether they work.

Bottom line is actually if they sound good and you don't sense any missing audio, you should be good.

Good advice. Without tweeters your music would sound flat and sound like its missing something. I believe the reason you cant feel it are several. When you feel a subwoofer your actually feeling the pressure waves in the air, partially because a large subwoofer moves alot of air. Tweeters move much faster and are in size much smaller and they move alot less air. In the end its nothing to worry about if the music sounds normal. If your concerned and want to hear what it would be like "broken" adjust the high bands on an equalizer in your music player and then play a song. It should be a big difference.
