SDA SRS2 versions???

engtaz

What were the differences between versions and does someone have the schematic for these one that has pin/blade?

Thanks

I know that 1 set only has 1 set of binding posts and the 1 I have has 2 binding posts.

I was looking thru the Compendium and I didn't see anything about different versions per se. But, on page 13 it does talk about the replacement parts which I guess is the same page that's online, too. The only difference I could see is that the pin/blade uses MW6511's for the stereo drivers and MW6510's for the dimensional drivers whereas the twin blade version has MW6509's for both the stereo AND dimensional drivers. The passive is a SW155 on the pin/blade version and it's a SW150 on the twin blade. It just says "Not Specified" for the crossover parts. Both use the SL2000's, too.

Also, on page 26 it also talks about that being the differences between the 86 and 87 version. Looks like the 86 version is the twin blade and uses the 6509 drivers. I would assume there are crossover differences, too, but who knows.

That may have not helped a lot but that's all I could find!

yes the crossovers are different. I was looking for the schematic for the pin blade SRS2's. the twin blade has speaker in parallel and when I took the speaker out of mine the stereo and the SDA speakers pairs were in series??????

See if these 2 scans will work. This is what is in the Compendium. Hope this helps!
