Is there a serial number/model number database?

[StantonZ]

I'm trying to figure out if I have 10A's or 10B's. There's no external fuse on the back and the tweeters are all black. I know the tweeters are different from my 4's, but I wish I knew if they were SL1000, 2000, etc.

Here are some pics.

The first pic is 10A's the second is 10B's

Maybe this will help you out.

No.

Can't you pull the tweeter and look at the back ?

[StantonZ]

Well, the (tweeters) are like NEITHER picture (although your pictures look the same): the coils go more horizontal, not angled down. I don't want to pull the tweeter; with my luck it will slip out of my hand and there goes the dome. I must have a 10B with some later model tweeter, although I remember replacing one of them years ago (like the late 80's) and all four match.

So, post a picture.

Didn't know it was that easy.

That's an SL2000. You might consider upgrading to the RD0-194-1 silk dome replacement tweeters from Polk. They are sweeter and much smoother.

Oh yeah, those are 10B's.

Thanks!

That is a cool question. Most SNs follow a sequence of some sort. If enough original owners post when bought and the SNs then a database of ranges (if Polk is not talking) can be framed.

Theoretically, they should have a database of every speaker (serial number) that went out along with what kind of tweeters, drivers, etc. were in them. But I have no idea how sophisticated their shipping & tracking was back when

[Toolfan66]

It would be intresting to know what the quanity was of each pair that was manufactured of the SDA's

[dorokusai]

It doesn't exist and wouldn't be available if it was....enjoy your loudspeakers.

apparently Polk wasn't that worried about keeping track of their loudspeakers. It wouldn't have been that hard, even back then, to keep track of the serials.
