SDA 1 Speaker Identification

Jamalinho

Hello Forum,

I'm from germany and i am considering to buy a pair of SDA 1 (B? C?) speakers.

As my dad owns a pair of SDA 2B real wood speaker I know of that superb sound of these nice vintage models.

As I'm from Germany, it's really hard to find any of these. Almost impossible.

So back to my question:
I found a pair of SDA 1 speakers, but from the pictures, I cant find out, according to the SDA Speaker Identification guide,
if it's a SDA 1 B or an early SDA 1 C.

Speakers have a blade/blade connection socket (unfortunately cable seems missing)
They have a bright brown wooden SDA 1B style cabinet.
Serial number: R SDA 1 5374 (hard to read, not 100% sure).

Any chance to find out if it's a 1B or 1C?

Greets from germany!

pictures would help tremendously or if you could pull the drivers for the MW numbers we could assist better

Look like 1Bs, with the vinyl removed

Mystery

Look like ugly lepricon without the vinyl covering.
BTW, the description of weight may be incorrect. It mentions 31 KG that comes out to 68 lbs. I thought they weigh more around 85 lbs that comes out to 38.63 KG.

Vinyl means the surface of the wooden parts?
Why would someone remove that? Probably not that easy to bring them back to a nice look.

For the model, sure with the 1B's? Thought the 1 C's a re looking the same.

Thanks so far for the answers.

What would be a reasonable price for these in this condition?

Most likely was because it was trashed and coming off.

As easy as putting on shelf liner. You could veneer them that would be harder to do and more expensive but look much better than vinyl

When it comes to Polk looks can be deceiving. Yes they look the same but are very different speakers. Both use different drivers hence the reason I said pull the drivers. Obviously you can't if they are on eBay.

200.00 or less....

One more question:
On each speaker, the 2 mid-speaker on the right look different to the left ones. Glossy speaker domes vs. matt speaker domes.

Probably 2 replaced midspeakers on each?

yes those look like new production Polk drivers. New drivers cover the voice coil leads that you can see on the others.(two little nubs next to dust cover) Both are made the same once you clean the older drivers they will match better

Thank you very much for yours answers! Very helpfull.
Of course I'd like them to be in better condition, but as it is almost impossible to get some of these over here, I'll think about it.

Far as I know:
ALL 1Bs had that style cabinet with brown woodgrain vinyl, and blade/blade interconnect sockets.
SOME 1Cs had blade/blade interconnect sockets. The 1C Studio version had the 1B-style cabinets, but in black woodgrain.

IF some or all of the 1C Studio speakers also had the older blade/blade interconnect sockets...and the woodgrain vinyl was missing...the ONLY way to know which series they are is to pull MW drivers.

1Bs will use MW6509 in all positions. 1C will use two MW6510 and two MW6511.

I think it's likely that these are 1Bs, but you'll have to pop a MW out to know for sure.

Well, missed them. Someone else got them for 1 Euro more

Gotta wait now for some more years to find another pair. Thanks again for the answers.
