Ringing Horn. SWR

Mine doesn't ring! I've been gyped!

 

exactly what are you calling "ringing?"
what does this "ringing" sound like? ( and don't say "ringing please. find another synonym for it.)

 

I always thought (and still think) SWR's hi-pass filter point for tweeters is a bit too low as I hear them harshing often. Maybe 1Khz up would solve this (just MY opinion based on MY tastes treble-wise).

SWR uses (or used to use) a capacitor to clean the lows out of the tweet, although there are those that think the cap is unnecessary I have found that without it you hear that harsh ringing sound.
Change the value up or down, the ringing harshness is the piezo element trying to reproduce a frequency that it cannot.
The cap value in my Basic Black is 4uf ... try a 3uf or a 2uf,
and see if the crap doesn't disappear.

 

If the tweeter is a piezo a 4uf cap wouldn't alter the high-pass frequency unless there is a resistor wired in parallel with the tweeter to present a resisitive load to the capacitor. If that is the case you'd alter the high pass frequency by changing the resistor value, not the cap.

If the element is piezo and there is a very low value cap wired in series with it, 1uF or less, that cap is an attenuator, and a lower value would lessen the sensitivity of the tweeter circuit.

On the other hand if the tweeter element is a dynamic and all it has for a filter is a cap then it should be replaced with at least a 3rd order high pass filter, in which case the crossover point could actually be lowered.

Either way curing the problem isn't possible without knowing exactly what's in there to begin with.
