25 - 40 Khz Tweeter

[canthai55]

Good morning.

Do not know if this is the right Forum or not, but as it has to do with speakers ...

 

Looking to purchase a few tweeters capable of producing the freqs above.

Sound quality not that important.

 

Also looking for an amplifier that can produce said freqs - and at that freq I do not believe I would need one very powerful. Altho' I would like it to be able to run 6 or so tweeters.

 

Internet search comes up pretty empty - only ones listed are for ultrasonic cleaners.

 

Any info appreciated. Thanks

As these frequencies are outside the human hearing range, I'm guessing your trying to scare something away? Unable to help with sourcing for you, sorry.

What you are looking for is a “super tweeter”…they can be cheap.

For an amp to help you run them you’ll need either an integrated amp or a separate preamp.  Can’t help you there as all I’m familiar with that is rated to those frequencies are quite expensive.

Thanks for the link.

I wonder - judging by the SPL V Freq chart, if the sound falls off rapidly above 20 Khz ?

Was just going to use a signal generator for the output to the tweeter if I can find one that outputs this high.

Google search of the inventor of the tweeters in the link came back empty

Will keep trying

You can enquire with the distributor; https://hifidiylive.aliexpress.com/store/3224006

though I'm not sure I would trust any frequency graph supplied. Chinese made products.

As expected - did not even get a reply, so ...

 

Am looking for a signal generator now. Freq range 25 Khz to 40 Khz

Or someone who can build one for me

Any ideas ? As tweeters are cheap I will just bite the bullet and experiment

 

Thanks All
