SDA-SRS2..Blades question

Tony M

I tried to solve this problem through the forum searchs but no luck. My newly aquired SDA-SRS2's have the blade / blade interconnect plugs. Now this might seem stupid but I can't find anything to reinforce that the wide blade continues to another wide blade slot on the other speaker. COMMON SENSE tells me it should. Why then , are the plugs in opposite settings? The wide slot is on top on one ,then the wide slot is on the bottom of the other. Was it just a manufacturing fluke or what?
I'm getting close to hearing these and from what I've read here, I'm in for a real treat.:D Then to redue the wood and cloth.Thanks

No fluke. The wide and narrow blades are wired differently inside each speaker. Refer to the SDA SRS 2 (1986 version) schematic in the SDA Schematics sticky post at the top of this section.

Tony M

Darque knight, thanks for your reply.I had already looked at that diagram (twice in fact) but was still confused. I still am a little, I now think, (because the diagrams state blue to white and black to white[I thought they went from wide spade to narrow on the other end per DIAGRAM]but was afraid of blowing something up by shorting something in the crossover)that you are saying ALSO wide spade on one end of a wire and a narrow spade on the other end.

DarqueKnight

Inside the SDA cable, the wide blade is connected to the wide blade on the other end and the narrow blade is connected to the narrow blade on the other end.

The two blades connect to different points in each speaker to complete the SDA circuitry.

Tony M

Thanks again.OK ..wide to wide / narrow to narrow. Do you know why the plugs are installed different? I have'nt tried to take a plug off, but it seems they should have the same orientation to keep people like me from scratching our heads:o

Tony M

Darque knight, I am refering to the sockets on the speaker cabinets being switched. Maybe there has been a little missunderstanding here or there. I have no interconnect wire. I am going to make one.

DarqueKnight

They are not supposed to have the same orientation. They are oriented that way to make it easier to tell the right speaker from the left speaker. There is a label on the back of each speaker that designates left and right, but labels can become damaged or be removed.

The cable sockets are not easily removed because they are hot glued on the inside of the cabinet.

Tony M

Thank you . It's making more sense now.I'll test the system later today. I'll look-up the SDA list of music to play and see if I have any. I'll reply here later. Thank you again Darqueknight!

Tony M

WOW.:D..WOW....WOW.....I've only heard Los Lonely Boys, ONDA.It was like the band was on stage in front of me!! Pink Floyd will come soon as will some others off the lists of favorites.Great design Polk Audio!!!!Thanks again Darqueknight!

DarqueKnight

I assume you are listening with your improvised SDA cable in place?

Tony M

Yes I am. I'm going to take each mid-woofer out and test each one to make sure one isn't dead. Also the balance test has to be done. That soundfield was pretty amazing though. I can imagine how much better it can get just from reading your posts in the forum here.What a thrill it must be to hear the BIG DADDY's. Maybe some day. (I did audition the BIG ones when I was about 20 once but wasn't impressed. I only heard a movie being played through them so I never really HEARD them at all.)I'll improve my interconnecting wire also later on.I'm a boy with a new toy:D

Well thanks ijust cut the rca and just leave the round pin . Iconect the pin cable its works perfect . Now the horizontal plug ifind one pair of smal type of connection and press down they fit into the blade ,so iam going to connect both ends and connect into the horizontal blade .

Enjoy the sda 2 they are good ibought an pair of klipsch fortes 2 pay 400 boxes iregret ibought my in such bargain and such good condition . Only one thing the cables and the small round center in one spkrs was inside ipull out but it already was litlle crash ,so super glue did the job . But the others ipull out looks perfect . By using needle thats the way . Few people know about it thanks . Igoing to buy small center in glue in the top . Thanks very much .pw

The Blade Blade interconect cable you can buy from Polk Audio, Your SDA 2's have a Blade Blade, and the Blades are "NOT" the same size. If i understood you right.

Welcome to America and Club Polk.

If I can order a new interconnect cable from Polk Audio cust. serv. ,by all means I will. I have the # already. Pw47,As far as the SDA2s go I'm sure pin to pin and blade to blade will be the way. Unless Toolforlifefan is telling you what you would have if they WERE SDA2s.

There is no Pin to Pin, eather Pin Blade or Blade Blade. Polk will "NOT" have the Pin Blade combo. Only the Blade Blade.

Some guys here on the fourm make the Pin Blade, or you can just make your own.

Tony M

Thanks Larry, I need the blade / blade so i'm in luck I think.....I don't know what PW47 needs because I don't think he knows which model he has yet. Right? More info is needed on his I think...

PW47

Tony M

PW47,Where are you finding these great speakers? You are surely hooked on the finer sounding speaker lines that are affordable to us finally:D. Go ahead and tell us what you paid. We can handle it ....maybe.;)

PW47

tony dont tell nobody ! first was 199us than 99us than 35 us !!!! from white, red ,blue . was missing the interconnections,so sound weak ,nobody wants so ....i search at forum and igot it in the right time . iam ver happy sounds really good ,smooth never tired to hear . and from 1 t0 10 igive 8 half cosmeticaly . i upgrd the pin cable by monster sound even better . ihave an pair of rt8 never impress me . r sda2 are really good . did you get thoses blades ? iask the customer service about the blade to blade! same size in my model ,no aswer . so idid miself but thin wire works ok ,but iguess with wide wire may improve quality. regards .

hy tony ,you order new pair of tweeters . You think its going to improve substancial upgr in the sound ? Tony itry to find photos of my r sda2 but nothing . Ithink my model is the early one one tweeter two mid bass , one passive radiator . Tony if you dont mind tell me how much the interconnet blades and two tweeters . Your spkrs they look good ithink they are more advanced than my . Ijust plug my klispch fortes ii . Tony they are really fantastic sprks . The site is going to finish . Now facelook . Ihave ahell lot trouble to log in . Regards pw

Tony M

They are around 150.00 . I just put two new ones in and can tell already the sound is smoother and not as harsh. I have two more to go..(100.00 more)..Listen to the veterans!! They're worth it.
Now...... your speaker model determines which replacements are used.Look around this forum and you'll find what you need to know. If you don't , just ask in this same area..

Tony M

The other two new tweeters are in now and yes they sound ALOT smoother:). If they are suppose to improve with use I'm in for more goose bumps:D.Still need to switch amps though....

Tony M

Forgot to post here, I now have a Carver Signature to put with these.:D
I still have to hook it all together though.I'm medically (frozen shoulder)derailed here at the same time. I'll tell you about my set up soon as I get it together.(myself and the system:D)

Tony M

I had to replace the sockets too. that was easy. working on the wooden caps now.;)

Tony M

They sound alot better now. the carver amp with a rotel pre-amp turned to 11:00 is loud enough!The speakers need the tweeking and cossover mods done but that will come later. Sada's Paradise was exquisite! then some pink floyd's Division bell....Impressive.Top rate sound ECEPT I'm hearing some distortion in a midrangearea. It's a raspy or reverberation of one or two mwoofers.It's not very noticeable until its' loud and 5000kh tone or voice.Might it be the crossovers?
wood work on the four side panels that get cloth will get new panels and cloth.they would then match with the new front grills my wife and I did about two weeks ago:p One side panel was damaged bad and broken. It's now removed completley
I allready made or fixed two caps, tightined another. one more to tighten later. The new BINDING posts work solidly and support the new bannana plugs I got from monoprice.com securely!..The chinch inter connecting sda cable works very snuggly.It's very,very solid now and its makes me wonder how people mess them up so much.I'm very enlightened to hear music in this way. I thought the monitor 10's were awsome:). These are super AWSOME . More Later.;)

nooshinjohn

congrats man! I am glad you are in love with that amp. Wish now I would have picked it up;)(j/k), as I am going 5.1 and will not need a 7channel amp to get the job done. I would LOVE to here your setup some day.

Enjoy!

John
