    Default SL2000 oil can resonance notch filter in SDA-1C's

    Does anyone out there have any information about the notch filter built into the crossover of the SDA-1C's?It is supposed to counter the 13 kilohertz oil can resonance of the SL-2000 tweeter:( .Does it have any negative affect on the RD-0194 tweeter?Does this newer tweeter have the same resonance since it was made using the the SL-2000 silver coil magnet assembly?Can this notch filter be disabled in the crossover?
    Thanks!

    Don't worry about it. The 13khz is a small peak in the crossover. Not to say the old sl2000 driver wasn't a little rough but the 13khz thing is a function of the crossover. I've read a lot of theories on this 13khz peak but if you graph the output of the crossover you will see it. The new tweeter sounds absolutely perfect, much better than the original.

    Didn't the crossover have a notch filter (as in taking a notch out of the signal at about 13 khz)to compensate for the resonance in the tweeter at that frequency)?It sounds to me like what you are saying is that there is a response peak introduced BY THE CROSSOVER?

    Ok so like i am TOTALLY having a bad stereotypical blonde moment heyeeerrrrr!!!!!!

    No, there is no notch filter in the SDA1C crossover.

    No, it actually goes up to a peak. I'm thinking that is where the 13khz peak story about the tweeter comes into play.
