1/2" Mylar Dome Shielded Tweeter 8 Ohm with 3.3 Ohm Resistor
1/2" Mylar Dome Shielded Tweeter 8 Ohm with 3.3 Ohm Resistor is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from GREAT SOUND!Bought these to rebuild some old horn tweeter that sounded terrible.Popped off the the backes of the old horns, and cut off the rear bowl.Then I took off the circular expanding ring on these thats that gives them a larger OD and super glued them one! sound 10x better. Really a great sounding tweeter.I have a 4.7uf Dayton film cap on there.

1/2" Mylar Dome Shielded Tweeter 8 Ohm with 3.3 Ohm Resistor

Is the 30 watt continuous rating the tested or rated power handling?

Were these tweeters tested to verify that they can actually handle 30 watts continuously with a 5kHz crossover? Thanks!
Asked by: Robocam
This is likely a rated power handling. Being a buyout item we have very limited information from the manufacturer.

Does the SPL rating of 88 dB/watt/meter include the resistor's padding effect?

Asked by: Clarkia
Yes this is with the resistor in place.

What does the resistor do?

What's the 3.3 Ohm, 5 watt, padded resistor do? In what circumstances would one use it or bypass it? Where can I learn more about this?
Asked by: Spaker
This is a cheap way of lowering the output level of the tweeter. These were originally intended for a consumer speaker system (I do not know what brand or model) and that design must have required a resistor on the tweeter for this reason.

Asked by: jayC
The resistor is wired in series with the tweeter input.
