Questions about recently acquired Polk Audio SDA SRS 2 speakers

Recently acquired a set of Polk Audio SDA SRS 2 speakers and had a couple questions. Here is some info on the speakers

* They have the pin/pin connection, did not come with an interconnect cable, so I just bought one on ebay

* One serial number is in the 800's and the top/bottom caps are pieces of solid wood glued together. The laminated caps still look new - no cracks, warping, etc.

* The other serial number is in the 1600's and the caps are veneered


Was this model was sold from about 1986 to 1988? A "late 80's" confirmation is good enough for me.


Is there any significance/meaning to the serial numbers? No idea how many pairs they manufactured per year at the time, and therefore no idea how long it takes to go from 800's to 1600's ........ or if I should even care.


Anyone else have a pair of these SDA SRS 2's where the wood caps mismatch (one laminated & one veneered)? I did have a quick glance of at least one person replacing the caps - love the concept, but do not have the time.

    I'm assuming you mean pin-blade interconnect? Pics would help.

    Yes pictures because there are two completely different SDA SRS 2 speakers. One built of the SDA 1b and one off the SDA 1c not to mention they used very different drivers.

    The interconnect is blade/blade - sorry for that brain lapse.

    I own a pair of them.

    I replaced the tweeters with replacement RD-0194's.

    Thanks for that info @Gardenstater! I did not know that a handbook existed, but after reading your post, I found this nugget (see picture). Is this the handbook that you reference?

    The B/b SRS 2 is more expensive to update the caps and the mw6509 drivers are as rare as hens teeth. The mw6509 was only used in the SDA 1b and the model you have. Probably the shortest run driver of them all.

    Thanks for the info. That is not ideal news about the MW6509 being rare, but I bought them without doing much research.
