Sl 2000 Hookup

edited March 2008 in Vintage Speakers
I just purchased a pair of monitor 10 a speakers. When I bought them the previous owner told me he had replaced the tweeters because one was bad and he gave the old ones to me also. When I got home I thought just to be safe I'd double check the repair work. From the forum I figured the black wire was the positive side and on the old tweeters they hooked up to the red dot side. White wire to the black dot. But I do not see any kind of color coded marking on the replacement tweeters which are the 2000 model dated feb 89. I do see on the back side of the plastic mounting flange what looks like a + sign etched on one side but I'm not sure. And nothing etched on the other side. He had the white wire hooked up to the side with the etched + in it . I think it's hooked up wrong but not sure. Can any repair expert help me out and tell me what to look for to figure out which side is + on the tweeters?

    Got that black wire is positive thing covered. But still need to find a real identification mark or test I can do to to find that positive terminal on the 2000 tweeter. Looking hard but really can't find anything.

    The tweeters that don't have a + engraved into the plastic are going to be the replacement rd0194. The rd0194 tweeter will have a colored mark glazed on the positive terminal

    He might have also put peerless tweeters in them which usually have a dimple on the outer dome. Pics would help. Is the dome clear like a fisheye or dark/black in color?

    I recommend installing one sl2000 (clear dome) in one speaker and one of the other replacements in the other speaker so that you can do a side by side comparison to see which tweeter your ears like better. Then walk back and forth from one speaker to the other to compare the two. All the different tweeters (sl2000, rd0194, peerless) sound substantially different so it's important to see which one you like the best and which one matches your equipment the best.

    There is also a $3 cap (2.2uf, 250v) you can put on the sl2000 between the positive wire and the positive terminal. See the links below for pics.

    i have swapped out over a dozen SL2000's in my time.. and in all honesty.... a few times i had the pos and neg backwards.. and I didn't hear any difference.. i know that doesn't help.

    but the old SL2000's will have a red dot on them for POS.

    As you know, black or blue is positive, white or green is negative. On the SL2000 tweeter the positive should be connected to the terminal marked in red or with a + marked in the plastic.

    Don't the SL-2000's also have a crude "+" molded into the plastic next to the positive terminal?

    Sorry but this is the best way to compare tweeters. Why not let AA/FA try it so they can give us their opinion. Not everyone has telepathic ears that can tell what tweeters and caps sound like without ever listening to them or doing a side by side comparison.

    Oh my God here we go again.

    I still say you need to try a inductor on your tweeters. Something like a .36mH in series with the tweeter. Report back when you've done so.

    The mods just might delete your post. We are discussing audio here which is what this website is all about.

    In the past, some ppl like cable a and some like cable b and some like banana plugs and some don't and that was perfectly acceptable but with tweeters and caps, everyone has to like the same tweeter or they get put on trial for treason :)

    No Carl, you are not discussing audio. You are pushing an idea you had that has been proven to be terrible. The OP didn't ask you anything about your bad idea, he just wanted to know which terminal was which. Another point that has totally escaped your fixated mind. It's time to change the channel as you're behaving just like you did before you were banned.

    I have all the proof I need. It's called 3 pairs of sda's running 2.0-2.2 uf/mfd, 50-250v caps on all the sl2000's. You're welcome to send your representative over to confirm this and have a listen.

    I haven't heard anything about your proof other than you think it's a bad idea.

    How many scientists do you think thought that going to the moon was a bad idea.

    The only confusion going on here is your unsubstantiated opinion and your unwillingness to respect someone else's tried and proven opinion.

    I wouldn't be making these claims if I hadn't thoroughly tested them.

    Fact, you're cutting off everything above 12kHz. Fact, you keep ignoring that proof. Fact, the OP NEVER asked about your screwball idea. Fact, not only have I said it's a bad idea, numerous others have said the same exact thing.

    I said my piece but if you want to keep howling at the wind, have fun. I've been using these caps for over a year. How long have you been using them. I keep forgetting to mention that EPO http://www.epohouston.com/ had tweeters for sale with caps already on them so this isn't a new concept. It's just new to you I guess.

    Nope; not audio. It's you pushing this idea of a cap in the tweeter in every single thread, just because you like the attention you get.
    The truth is, you're only confusing people, and that's not good.
    If you like your tweeters with a cap, that's perfectly fine with me. But don't go pushing this idea to everybody without some kind of disclaimer. You could try:

    "It works for me because I am _________, but this is not recommended by Polk. Polk designed a replacement tweeter that most normal people prefer".

    This isn't any different than the cable debate so knock yourselves out.

    You'll have to ask polk why they decided to come out with new tweeters instead of fixing the perceived problem at the crossover level.

    Yes it is different; cable debates are just that, a debate. I don't recall anyone posting like a **** "use this cable, use this cable, use this cable, you should use this cable...........".

    Because it couldn't be fixed to their satisfaction at the x-over level. Do you ever do any research before you just post random things? Don't you think it would have been a hell of a lot more cost effective to fix it at the x-over than to R & D a completely new tweeter. This is such an old discussion do a little research and you'll understand why they R & D'd the sl3000 and then the sl2500 and then the RD0's.

    Hello:
    Guys thanks for all the advice. I did go with that black wire to the etched + terminal and everything seems good.
    Some body told me that it's not so important to get the tweeter hooked up right but you will really run into big problems if it's a midrange or woofer.
    As far as selection of best tweeter I'm thinking about cutting several more holes in the box and put all the tweeters on a selector switch. And invent a new model called monitor10A select. Then you can walk up to the speaker box and turn the knob to the tweeter you prefer.
    What do you guys think of that?

    There's no reason to do that. Simply install tweeter x in the right speaker and tweeter y in the left speaker and walk back and forth between the 2 until you decide which one you like better. Then install the winner in both speakers and enjoy.
