Just got a set of SDAs CRS!!!

crsthunder

Ok i have just got a set of SDA CRS and just want to know a couple of general things about them such as frequency response and room placement.. I am running them on a Hafler five hundred and using a yamaha rx-v692 as a processing unit for now :cheesygrin:

Thanks, Trey

chumlie

Welcome to CP. I'm sure someone with CRC knowledge will help you out. Happy labor day !!

Nice speakers! They like being near walls, but play with it a little as they are different in each room. Frequency response should take them down to 40Hz range if I guessed.

F1nut

One tweeter per cabinet or two?

crsthunder

one per cabinent :cool: one of em needs a tweeter im guessin sl2000

F1nut

In that case, you have CRS+'s. Overall - 25Hz to26kHz. -3db is 42Hz to 20kHz.

Place them parallel to the back wall, no toe in. Try 5 to 6 inches off the back wall. They need 3 feet from any side wall and should be spaced from 4 ft. to 8 ft. apart. Do you have the SDA cable? Do you have the stands?

Buy two new RD0194-1 tweeters directly from Polk or there is an upgrade that involves adding a 5.8uF cap to the crossover and then using the RD0198-1 tweeter resulting in mo' better sound. Regardless, throw the SL2000's in the trash can as that's the only place they belong.

As I'm sure F1Nut is leading into at least a....get the tweeters replaced with the new Polk RD-0194 as a pair. It's much better and toss the other SL2000 in the trash, it's a garbage tweeter. The next steps are a world is your oyster issue but I'd get the tweeters replaced and spend some serious time with them before listening to any further suggestions. I'm sure this will fall on deaf ears since you're about to get every recommendation under the sun.

If anything, at least listen to them as they are, after repair, and wrap your head around it before you ruin the whole effort by over thinking the project.

My ultimate vintage SDA CRS+ would be one with Polk RD-0194, Toolforlifefan's rings, Dynamatted or otherwise dampened mid-bass baskets/frames and Vampire Wire binders to include a better SDA Interconnect as a side project. As far as replacing Capacitors, Resistors, Inductors and blah blah blah....nope. Unless they are out of spec, which 90% of them are not, I'd let them stay as designed and cry into a pillow later. Just those simple things will change your life....the rest is for the 1%'s and toilet engineers. Not that it doesn't get better....anything can get better if you spend the money on it. GOOD LUCK GREAT SPEAKER.

crsthunder

Thanks and according to polks website they drop to 24hz and i believe that is probably accurate

LOL...Does that mean if I karma my SL2000s, no one will want them?:eek:

Thanks and I love the sound before these I had Klipsch KG4.2 with titanium diaphgrams and so far im pretty sure the CRS are eating their lunch so to speak :cheesygrin:

Get the new tweeters, recap the crossovers, and they'll eat them for breakfast , lunch, brunch, supper, dinner, and midnight snack.

nspindel

I'm getting ready to finish off my CRS+ mods, as soon as I get the resistors I special ordered and find time to hang with my bro-in-law in his wood shop and do the veneer work. Pound for pound, the CRS+'s are the best of the SDA's, in my opinion. Sure, you can go bigger and better. But you start getting into very huge speakers. For a tiny speaker, the CRS+ is breathtaking, and you will very quickly forget that you're listening to a small speaker. I would actually stick with the SL-2000's for now, while you settle in with them and decide if you want to invest time and money into making them even better. If you're going to do work on the crossovers, then you're a capacitor away from using rd-0198's. If you're not touching the crossovers then you can upgrade to the rd-0194's as-is. But if you're not ready to make that decision yet, stick with sl2000's for now and don't spend any money until you know the direction you want to go. Either way, you'll find plenty of advice here on what to do with them, there's a lotta love for the CRS+'s around this place.

The OP said he needs a tweeter, so I'm guessing one of the sl2000s is defective or missing all together

nspindel

Ah, I missed that. Crsthunder, I have the sl2000's I pulled from my CRS+'s. I haven't listed them for sale yet, I have a bunch of odds and ends I'm going to be selling. You can't pm yet I don't think, but send me an email thru Polk if you're interested. I want to sell the pair of them, but sl2000's definitely don't break the bank. I also have the pin/blade cable if you need one.

He has to buy a tweeter. Get the RDO-194s, drop right in, no changes. Call up Polk Customer Service, tell them you're a member of Club Polk, and they ship free. I just ordered a pair last week, with tax it came to $105.00 if I recall.
The SL2000s SUCK. If he really want's to hear what they're capable of, it's the only way to go.

nspindel

I disagree with that advice. You shouldn't be spending $100 on tweeters for TL-upgradable SDA's until you've decided whether you are doing the TL upgrade or not. Somehow I managed to listen to CRS+'s for 17 years with SL2000's in them and still loved them. Yes he should upgrade, but not until he knows whether he is going to need 194's or 198's.

Well of course you disagree, cuz you want to sell him your pair of sl2000s, which SUCK.
He has to buy a tweeter anyway, let him make an good, initial investment. The 194s are light years ahead of the 2000s even without upgrading the crossovers.

nspindel

Ok, now you're proving to me that you're a worthless troll.

I've helped dozens of people out on this forum in the 7.5 years I've been here. How many people have you helped out with your 71 posts? You really think after I've built up a good reputation on this forum over almost 8 years, that I'm really just trying to sucker a new joiner into buying a pair of SL2000's? If I post my SL2000's in the flea market, they'll be gone in a day. See, I know that, because I'm now modding my fourth pair of SDA's, and have done this before. I'm not at all worried about selling stock SDA parts. They're gone in a heartbeat.

The OP has not even hinted at any desire to start making changes to these speakers. As such, I'm giving him the cheapest option to get his speakers working. A pair of SL2000's will cost him less than a single RD-0194, he'll have a spare, and when he does decide what he wants to do (if anything), he'll be able to sell them and get back 100% of what he spends, except shipping. You're telling me that 194's are a good investment when he doesn't even know what a TL mod is yet? Tell you what - why don't you buy the 194's for him? Obviously $105 is just pocket change to you, considering that long-term they may not be the right tweeters for him.

Go crawl back under your rock, troll, and learn a little respect. You go accusing long-time members around here of just trying to sell their spare parts, you'd better start running for cover.

First of all, not a troll. I do this for a living as well as a hobby. Telling someone who has already stated that he really likes them, to buy a pair of 20 year old tweeters, one of which he doesn't need, is ridiculous. That's money down the drain. I suppose F1nut is a troll as well since he essentially gave the same advice? If I had a spare SL2000 I'd GIVE it to him, but I don't, I sold them all on ebay. Because I have 71 posts doesn't make me a troll, and 2271 doesn't make you Mother Teresa. Where I come from respect is earned not given. Giving poor advice, then calling me a troll and telling me to crawl under a rock, is not deserving of respect.
I'm done with this conversation. The OP can certainly make up his own mind

nspindel

He can sell the SL2000's when he's done with them, and recoup every dime he spends. You're telling him to spend $105 on tweeters that he has a very good chance of needing to replace when he gets his read on about the TL mod.

Someone with 71 posts over the course of a year, who gets on a thread and accuses a long-time member of just trying to sucker someone into buying his spare parts, is a troll. I don't care if he buys them or not. If he doesn't, I'll put them on the flea market and they will be gone. Just like yours were on ebay. What I'm doing is giving him the lowest cost option available to him in order to get his new speakers working.

I don't give a damn if I have your respect or not. You'll be back under your rock soon. Jesse, on the other hand, has an overflow of respect from me. See, he's earned it. Doesn't mean he and I will necessarily agree on everything 100% of the time, but afterwards, we go back to being good friends. But I know him well enough to know that he will agree with me on one thing, and that is that you are a troll.

To the OP, I'm not saying that you'd be unhappy with RD-0194's. I've got four of them in my 1C's, and actually ordered them before I even took possession of my 1C's. But that's because the 1C crossover is not TL-moddable, and the 194's are my only option for upgrading the tweeter. In your case, you have a speaker that can be modded rather easily to accept the RD-0198, which is a better tweeter than the RD-0194 (and costs exactly the same). So if you buy the 194's now, you may find yourself in the future wanting to do the TL mod, in which case you'll be selling the 194's at a loss. If you buy the 2000's from me, the two of them shipped would cost less than a single 194, and when you do eventually sell them you'll recoup all of your money. So if you think you may do some mods at some point, my advice to you is simply to spend as little money as you possibly can so you can enjoy your speakers right now, with as little as possible spent until you understand your options. Feel free to take my advice or not. But I am most definitely not trying to push you into buying my 20 year old tweeters. If you don't want them, someone else will. SL2000's sell in the flea market all the time....

gudnoyez

Congrats on your CRS+s I know you are going to enjoy them. I also came across a couple of pair and love them. I plan on modding one of the pair this winter for something to do once the snow flys. I will get the RDO's and hope to get VR3 to update the crossovers for me, and get a set of rings from Toolfan. I think they sound great stock can only imagine how they will sound with the upgrades. I guess you could say I'am actualy looking forward to winter. Once again enjoy them.

Solid Advice. I have a friend with 2Bs in the same situation.

DollarDave

Or, buy the 194's now and enjoy the speeakers without punching holes in your ears with the SL-2000s. Then, down the road, you can sell them, the extra SL-2000, and toss a couple bucks in and get the 198's.

He could certainly do the same thing with a new pair of RDO-194s, enjoy the improved performance right out of the box, and if he decides to rebuild the crossovers and do the TL mod and RDO-198s, he can sell the 194s and recoup 90% of what he spent on them

Dave, the 194 is a better tweeter. Zero argument. But I do think the sl2000 thing is a bit overblown. I bought my original CRS+'s in 1989. I upgraded the tweeters to 194's in 2005 when I joined this forum. Not once in those 16 years did I say to myself, "You know, these would be awesome speakers if they only had a better tweeter". I loved them with sl2000. Then I put the 194's in and loved them more. Upgrade the crossovers and they're even better. And so goes the story. Polk sold a lot of speakers with the sl2000, to a lot of happy customers. I'm not sitting here defending the tweeter, and I'm not saying the 194 isn't a lot better. All I'm saying is that there are very inexpensive options here to get these speakers working out of the gate. There is also the argument in favor of listening a bit with the 2000, then upgrading, so you can appreciate the difference.

In fact, if the OP wants to get a single Sl2000 I'd be fine with splitting up the pair. He wouldn't need two tweeters. I'll sell the other one in the FM.

That is, if we haven't scared him away and he's out buying a pair of Klipsch right now!

westmassguy

We're all assuming the OP indeed has a defective tweeter. I could be a loose or corroded spade connector, or with the CRS+ it could also be a dodgy Polyswitch. He needs to do some rudimentary troubleshooting.

Now that is some solid advice....

Simplest way to do that without any meters is just swap the SL2000's between the two speakers. If the tweeter is not functioning in the opposite speaker, you have a bad tweeter. If the issue remains in the same speaker, it's something electrical inside the speaker.

And if both tweeters work properly after the swap, the connector most likely had some corrosion on it.

edwardm10

The CRs+ are great little SDA's. I've had mine for about 5 yrs now and LOVE them. I started with the stock SL2000's and about a year later upgraded to the 194's, which wre a wonderfull improvement. I'm now going to do the TL upgrade and can't wait to hear the difference. Give them a listen in stock form and go from there
