New to site, SDA 1.2TL questions

Posts: 11
I just picked-up a pair of SDA 1.2's for $100 on Craigslist. The only thing I could find wrong was the covers, which I replaced immediately, and no interconnect cable. I am a Marantz enthusiest and am looking to upgrade to the Holy Grail "510" amp. Old school 350 WPC @4 ohms! Will this be enough juice to get me in trouble with this end of town? I also understand that there is plenty of info on this site for how too's with these. Didn't really know jack about these until I got them home and did some research. Can you guys help point me in the right direction to get my SDA's sounding the best possible.
Happy new owner!

Good God, $100 for a pair? That must be the SDA deal of the decade. 1.2s or 1.2TLs?
The usual line is that they sound best with at least 1000W per channel. I can tell you from experience that in a small (too small, actually) room anything higher than about 40W on the meters will cave your head in. A guy on AK used to drive a pair with a 500WPC McIntosh amp but he sold it because the meters never moved very far off 0.
Of course, as the room gets bigger and more dead the power requirements go up. -
Wow, what a steal. Congrats.
Others I'm sure can help you more than me but I'll start off there is an SDA compendium you can get which will have an abundance of information about upgrading your 1.2's, from crossovers to tweeters and back. -
nice score Buck.. and your dream Marantz amp, will be plenty of juice for those SDA's.
congrats and enjoy.. ask more questions.. as the SDA's hold a special place in people hearts here and there are tons of good people as well as good info.
welcome aboard!

1.2's for 100 bucks...how is that possible? What type of 'favors' accompanied those 100 simolians?

Awesome score! Congrats.
The cable is an easy work around.

Good grief. Never in my neck of the woods! Great find...you'll love them! Like Troy and others mentioned, if yours have the pin/blade connector, you are in business easy. There are lots of topics in here as to how to make them work temporarily using an RCA cables center pin section. You can also drill a hole in the terminal cup (I think on those) and add a single banana binding post connector and use a larger gauge cable.

Geez, it sounds like Santa came early in my house. This is awsome, I really appreciate the response on my first posting. I'm not sure I even want to know what they are really worth, what I do know is I really have come to appreciate great audio! As far as the interconnect cable, would it be best for me to wait and order the stock cable, or is there a better method. I have read that the book Compendium(sp) is the bible for these? Should I wait for the new addition, or order the current edition? Also how do I go about ordering. I will very much enjoy sharing with you guys the metamophisis of these speakers. I believe a couple of the tweeters are a little out of whack, and it also sounds like there are some other things I can do with the crossovers, mids/woofers. Is it customery to try to keep these as close to OEM as possible, or, use the techniques that are in the book?
Sorry about all the questions, I'm a stoked beginer

The tweeters won't all sound the same. They come on sequentially depending on the frequencies being played. I'd listen to the speakers for a while to get a good baseline opinion before starting with any mods.
In the meantime, keep in mind with the standard interconnect you can't use these speakers on non-common-ground amps. You need an isolating interconnect for those, like Polk's AI-1 cable.
Oh yeah, what you paid for them is somewhere around 1/15 to 1/25 of the going rate.
Edit: Sal's too quick -
There seems to be some confusion as to whether you have 1.2's or 1.2TL's, so if you could tell us exactly which ones you have, we can point you in the right direction. Until then don't do anything.Political Correctness'.........defined

1.2s and 1.2TLs are nearly identical other than the appearance of the tweeters. Most 1.2s will have the same crossover bolt pattern as the TLs, and they all have the same mounting point for the bass brace on the back. The original SRS is the radically different speaker.
If your tweeters have silver/clear-ish domes, straight "Polk Audio" markings, and two lines of silicone caulk, they're SL2000s which would mean 1.2s. If they have black/silver-ish domes, round "Polk Audio" around the dome, and no caulk lines, they're SL3000s and therefore 1.2TLs.
Of course, that's not taking into account a 1.2 that's been TL'd, or either model that's been upgraded to silk domes. -
My SL3000s on my 1.2 TLs had more of a black/brass dome color to them.
Post some pics of them with the baffles off as well as pics of the back plates that may help us to help you identify them . . . Oh yeah F1nut is right, until you find out what they are DO NOTHING!:) -
That's alot of venison.

I suppose I might say mine are sort of a black/gunmetal, but it's hard to describe.
You mean take the grills off? Baffles might be tough without a chainsaw.
As fas as the cable, the 1.2 and the 1.2TL use the same one as far as I know. Pin/blade and capable of using an isolating transformer. -

The Compendium is out of print and there are no plans for another edition. As you have already found out, there is a wealth of knowledge and information here on the forum. Welcome.Proud and loyal citizen of the Digital Domain and Solid State Country! -

I think you are thinking of bezel. -
I bought these speakers about a year ago (sda 1.2s) and have yet to hook then up due to space limits. I am now wanting to listen to them. I am wondering if I can power these speakers with a single Hafler DH-500 for the lows and bi amp with 2 Quick Silver Mono Blocks (100 w) for the mids and highs. I think I heard somewhere that tube amps do not work with these speakers.

Welcome to the Club Polk Forums Buck! I am a Marantz fan also. I have a 510M amp but I do not use it on my big SDA's. It works fine, my preference is to have a little more power. More power doesn't necessarily make the speakers play that much louder, but it does make them sound better at lower volumes.Carl -
Welcome and you got the deal of the century at $100. Make sure you use the cable (they can be made very easily since it wasn't included) otherwise you get no SDA properties and that's what makes the speakers special. Also the Compendium is no more, all sold out, and there's not going to be another printing of the 2nd edition.
Take some time and read the forum there is a load of info both general and specific about SDA's and your model. Ask lots of questions if you don't find the answers in your search.
Good luck and most of all enjoy,
