Another piezo thread!
I've got a couple of the twin driver CTS ksn 1177 tweeters. They are very efficient and nicely designed with a different damper on each half to smooth the output.
They don't have the power line protection and I'd like to add something like that.
I have a handful of ptcs from the bay and am thinking something like 27R with a tripping current in the tens or low hundreds of ma.
I'm thinking the calculation should be around 18V RMS over [email protected] at say 10khz. Based on 75w at 8R.say 140ma.
Any better thoughts?
Where to start with sizing a bulb in parallel?
