Hi,

I'm interested in experimenting with tactile tranducers but I'm not terribly versed in how wattage ratings will affect them. I've been looking at some cheaper 8 ohm transducers that can handle about 3-5W rms. I have an amp that supplies about 25w. Now I'm thinking this will literally destroy the transducer and that I should go with a more expensive one that can handle 25 watts. Is my understanding of this flawed and the cheap ones will be fine?

Thanks!

You could build an array of such speakers connected in series and in parallel so as to give you 8 ohms impedance. The array of 8 such speakers could handle 25 watts.

 

You could refrain from turning the amplifer as high as it will go. That will send less power to the speaker.

 

Keeping the volume down will keep the transducers from being over loaded. If you are worried about someone turning the volume too high, you can add a normal (not slow-blow) fuse in series with the speaker connection. A 700mA fuse will limit the power to about 3.9W.

Yes!! I like that answer. Also, fuses can be your best friend.

 

great. thanks for all the responses!
