SDA SRS 2 need CPR and ICU life support
Hi everyone. Brand new here. Been reading alot over the past few days and you all seem very passionate about my new interest.... my "new" vintage finds.
They were beat up pretty bad by the evil previous owner. And I got them for a steal. And now want to bring them back to greatness. The components all seem in fine shape. no rubber rot or pushed in covers. No frayed wires. and the "inner" enclosure still seems solid. All seems well under the hood.
Since I brought them home, I've been reading here about the crossover refresh and the tweeter upgrade, so I'm interested in both of those. Also need to find out where I can get the SDA interconnect cable, mine is blade/blade. Something weird is that the post cup doesn't look like the one listed on Polks model ID page. Mine doesn't have four posts, each pair connected with a wire pigtail. Mine only has two posts, and three little holes above. Are these some type of connection for something? And my blade/blade interconnect terminal is not in the cup at all, but way down on the cabinet back, several inches below the cup. I'll get pictures up. So I'm interested in advice on the crossovers, the tweeters and the interconnect cable.
And, I'm going to address the looks of these ragged old girls. The walnut top cap on one is cracked in several places and somebody did a horrible job of a restain (slapped on some paint on all wood surfaces). The fabric is shredded. and the side panel on one has been NAILED!!!! back on. I think I have all this under control... and will certainly post pics of the "before", during and after transformations. Plan to strip all wood, sand, restain, all new fabric, etc. A good Thanksgiving project.
Somebody on one of the posts I read asked that if anyone was going to disassmble this model, to let them know, they needed some measurments of something. I'll try to find it and contact, but I've read alot, so if its you, let me know... I'll have these gals in many pieces.
Wish me luck!!! (pics coming soon) (sorry for the long intro post)
OK, this gets uglier before it gets better
Seriously, please go back if you aren't prepared for this. The dismantling began tonight.
Now remember that the these speakers have an "inner box" and the surfaces are all cosmetic. And my cosmetics were in dire shape. I say that because some of my tools were not really precise and....well, let's just say that most people probably don't work on their vintage Polk speakers with.... a machete.
Its not too late to turn back.... OK, the side wood strips were trashed and the only way to fix them is to remove them. Same with the side panels that are fabric over pressboard. and the caps and bottoms. It all needs to come off. New fabric is on order and on its way.
So, the side panels came off easy on one of the speakers. fell off one side after i removed the nails, and the other side just needed a little prompting.
Not so much on the second speaker... they must have used alot more glue. Had to get creative...
And it didn't go so good.
But this is just pressboard, and wrapped with fabric. So I'll just have to replace this pressboard, and wrap it in new fabric and reattach. Should be easy. What was the important part in this step was to remove the walnut (or oak?) strips in one piece. They came off easier and are fine.
So now, over Thanksgiving... stripping (the stain/paint!) sanding, restaining, a little cutting new pressboard, new fabric, and reassemble.
A question. What color to stain? Stick with classic original walnut? Looks kinda 80s. Go with a deeper more timeless color that's not original? Or... all my other wood audio gear is black. I would never paint these black... But what about a black stain? You'd still see the wood grain, and there would still be depth. But they would more match the rest of my gear. Is that blasphemy? Half of me thinks it would be. Weigh in and let me know. 1)Original walnut tung oiled? 2) stained a deeper warmer dark honey antique oak? Or 3) stain black and do a poly rub to give it a little sheen?
