Replacement for Sl1000 tweeter?

Hi All,

I am a long time reader and first time poster to the forum.

I recently picked up a pair of SDA 1 "Signature Edition" speakers for $200.00 in great shape off CL. One of the sl1000 tweeters is dead and I am trying to decide on the best replacement for it. I've got a line on a set of four Peerless tweeters model #810665 rated at 8ohms. Would these be a viable replacement?

Any help would be appreciated as I own a number of Polk speakers but am new to the SDA line.

Thanks for any info you can provide,

Farrell

    you should replace the SL1000 with the RDO194 from Polk... they are smoother and are the recommended replacement. the only drawback is that you will have to enlarge the cutout for the tweeter by about 1/4" or so. I just took out my SL1000 tweeters today and the differences are worthwhile.

    Thanks for the info!

    Does anyone have a sl1000 for sale that I could use in the meantime until the cost of four RDO 194's are in the budget?

    Keep your eye on the For Sale section as SL1000s pop up from time to time on there. Also, ebay can be a good source for used Polk parts.

    Have you swapped the bad tweeter with one that is working to make sure the problem follows the tweeter?

    Thanks for the suggestion.

    Yes, I did switch the tweeters posistion and the culprit was still dead.

    Would an Sl 2000 pass for a temporary replacement?

    The sl2000 is the best polk tweeter ever. You will love it. You will have to enlarge the hole to use it.

    Don't listen to this advice. If the engineers at Polk thought the 2000 was "the best polk tweeter ever", they would have gone the way of dozens of speaker makers and would have been out of business for many years by now.

    Fact is, the 2000 sucks. Period. End of discussion. Clean up your stupid signature line and grow up.

    Don't

    You have a right to your opinion and I respect that.

    I don't have the statistics but if the sl2000 was as bad as some of you think, I don't think polk would have sold more than 5 or 10 pair of the sda's. The popularity of the sda's was and still is due to the fact that they developed an incredible tweeter called the sl2000 and thousands of consumers were willing to pay $1500-$3000 to purchase them.

    The popularity of the sda's was built on the back of the sl2000 and it deserves a lot of the credit for the sda's "legendary" status and unending popularity.

    don't use an SL2000 tweeter in your SDA 1's. keep looking for another SL1000 or get the replacement.

    Just think how many MORE they would have sold if they came with the RDO's in the first place.

    I would venture to guess that 99% of sda owners have never heard of this forum because they have never had a problem with their stock sda's and are 100% satisfied with their stock sda's and that includes the crossover and the tweeters.

    They used them gently and never overdrove them or underpowered them so they never tripped the polyswitches or blew a tweeter or a driver.

    Generally someone that pays $2000-$3000 for a pair of speakers is not going to abuse them.

    Another vote against the SL2000. Every village has a village idiot.
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    Interesting. If you really believed this, why you would spend your time and money modifying them and preaching the "benefits" at every opportunity? That's a rhetorical question, not one to start this stupid debate again.

    You say they are perfect and you have all your SL2000 modified with caps.

    Thanks to everyone for your advice and opinions!

    Based on what I've read here, I just pulled the trigger on 4 new RDO-194's from polk. Should be here on Monday. The tech said they should be a drop in replacement with out any cabinet modification required. We'll see:)

    WRONG!!! The RDO194 are not a drop in replacement for the SL1000, only the SL2000. The faceplate on the SL2000 and RDO194 is about 1/4"-1/2" taller than the SL1000. I just replaced the SL1000s on my Polk Monitor 10s with the RDO194s. I had to use a RotoZip to enlarge the cavity in the cabinets. Was real simple with the RotoZip and using a fence to make a straight cut. It might be a little more difficult with yours since you may have to cut 1/8" on each side to keep the tweeter centered (the SDA has the tweeters rotated 90 degrees from mine).

    I was told the same thing for my Monitor 7's, maybe there is no cutting required for SDA cabs?

    Irish, as Jon mentioned, you probably will need to drill new holes though. Having owned SL1000's, the RD0's will be a nice improvement.

    Good to know, thanks.

    I may have to move the gold "Signature Edition" plaque then as it's only an 1/8" from the bottom inside edge of the current tweeter. Is the Rdo-194 just
    taller or is it wider than the SL1000 as well?

    Just received my RDO-194 order from Polk today. Unfortunately they sent me only one tweeter instead of the four I ordered:(

    Thankfully, no cabinet alterations were required on my SDA1's as the RDO just dropped in. I did have to drill new holes as mentioned by Face.

    Can't wait for the remaining three to arrive to complete the upgrade.

    I'm sure glad everyone does not dislike the SL2000T I am about to sell my 3rd. set on ebay in less than 24 hrs. They always sounded good to me. But I have not gotten a chance to hear my RDO's yet .
