I just bought my first SDA speakers yesterday for $200 and they need two new tweeters and the SDA cable. Can I replace my SL2000's (which have a red SRS stamp on the rear label) with any SL2000 from another speaker (say model 8 or 10 from ebay), or does it have to have the SRS stamp? Also, if I were to upgrade tweeters, is the SL2500 (from newer model 8's and 10's) or the SL3000 a better tweeter? These speakers were pretty inexpensive and I dont want to sink too much money into them and ruin a good deal. Next, how do I make a new SDA cable, as I understand the blade/pin version is not available for sale. I noticed a few threads about soldering ends on some speaker wire, but there is mention about common grounding and things which I am unfamiliar with...can someone help explain the home manufacture process. Thanks!

Sounds like you need one of these:

Welcome and congrats on your purchase. You can (and should) get the new silk replacement tweeters from Polk customer service; just give them a call and mention you're a forum member. You'll get a discount plus free shipping.

If your interconnect is the pin/blade, you can just use any decent speaker wire to connect the pins. You do need a common ground amp to run these speakers.

Good luck!!

Also, for the pin/blade interconnect you can take the speaker wire--12-14 guage,insert into a male rca connector,remove the "collar" from it,and you will have a decent/secure homegrown cable.

How can I get one of these Polk Compendium books? I tried to send a message to DarqueKnight but because I am a new member I can not send private messgaes yet. It really looks like a great resource and exactly what Im looking for.

But does anyone know if these mid-woofers , with all sorts of varied 65** numbers are interchangable? I was thinking of buying a pair of the smaller bookshelfs for parts but am not positive the drivers are exact models.

Thanks for the help!

Thanks! How do I contact Darque Knoght? I tried sending a personal email but the system will not allow it since I am a brand new member. The compendium looks like a great resource.

Also, does anyone know if the all the 6.5 inch midwoofrs are interchangeble? If I were to buy a small bookshelf set for parts, could the woofers be used in the larger SRS series?

Thanks for all the help!

HT Rookie,,,this may be a stupid question, but whats a common ground amp? I am running a HK 120 WPC receiver to them now, but may buy an older Adcom, Onkyo, or Carver amp to power them using the HK pre-outs in the future. I have to wait and see what they sound like when all is fixed- I havent even fired them up yet.

Adcom GFA 555 mk2 Common ground...Carver TFM 55x common ground. If an amp is selectable to be bridged is is USUALLY common ground. Always check with the manufacturer .

If you have a multimeter, just measure ohms between the negative binding posts (black speaker outputs); you should read 0 ohms (or very close to 0).
Most amps are common ground, but there are a few that are not; if you use a non common ground amp, you might fry your speakers/amp/both.

Not all MW drivers are the same, and some are not interchangeable; in this link you can find a list for your speakers:
