    The SL2500 measured @ 6 Ohms. what is the resistance of the SL3000?

    The DC resistance of the SL3000 and RD-0198 tweeters is 5.6 ohms. However, I must caution you that two tweeters of similar, or the same, DC resistance will have different impedance characteristics under AC load. This difference may damage your amp and/or your speakers...and the damage may occur slowly over time rather than by immediate failure.

    Let me start off by saying that I have been using a pair of SDA 2B's since the mid 90's.

    I have used the SL2000, the RDO194, and currently, the SL2500, which I find to perform the best.

    There was another forum member who thought the RD0198 sounded better in his SDA SRS speakers than the SL2000/RD0194 tweeters that were made for them. His joy lasted for a little while until his amp shut down on one particular song.

    With the 13Khz peak of the SL2000, and the ringing of the RDO194, plus the rather rough crossover point between the drivers, I have not been completely happy until now.

    Would you give an example by naming a particular song and explaining how the tweeter ringing affects the sound quality of that song?

    The SL2500 is smoother and more transparent, with better timberal accuracy, with a small trade-off of being a bit thinner in the low presence range do to using these tweeters without the added capacitance.

    I have run various frequency sweeps, and haven't found any obvious holes in the response.

    I don't doubt that this tweeter substitution sounds better to you. Some of us here, myself included, have done extensive modifications on our SDA loudspeakers. One "mod" we don't recommend is using inappropriate replacement tweeters and drivers. Tweeters and drivers should be thought of as major components of the crossover circuit. As such, they should not be switched out without proper regard to how the switch will affect the overall performance of the crossover circuit.

    BadSoundMann1,

    F1 is correct in saying you won’t find one person here in agreeing with what you’re doing is right, as well as you do not have 2BTL SDA’s, what gear are you using with these speakers?

    Yes I do! TL tweeters make TL speakers!

    No, you do not...

    Agreed. Reminds me of the fellow who was rabidly adamant that the only way to "fix" the SL2000 tweeter was to put a capacitor in series with it.

    For the record, I never called anyone a derogatory name...

    I see you removed my post so this must be pointed at me.

    I was not aware that the word "Circus" was derogatory...

    Thanks for clarifying. The rd0194 is indeed a ringy little bastad. I've heard yet another set that had the same issue as mine did. Monitor 10B's with a new set installed too.

    So saying anything at all that might actually get through to the OP that he does not have TL speakers even though he is using the wrong tweets, no matter how thick headed the individual might be, is off limits and he should be allowed to live with his delusion, and to try and convince others here that he is correct in his false belief?

    How about a word from our sponsors, either here in this thread, or privately, telling him he has bad information, explain to him why he is wrong, and suggesting to him the correct path to get what he wants.

    It would save us mere mortals that have extensive experience over decades of owning and upgrading these speakers from beating our heads against the wall.

    There must be something else going on with the speaker... crossover issue perhaps?

    Well I know I'll take the word of long time knowledgeable members 9 days a week and twice on Sunday over that of a confused newbie.
