Looking to find new capacitors for these Sony SS-1500s. There is no sound from the tweeters or mid range drivers on one of them. But when I touch them with the speaker wire from inside they work. The other speaker sounds pretty good. The grilles and cabinets are really nice. Can anyone suggest some new capacitors? I figure it’s worth a try. Thanks.

Depends on what you want as far as price or "quality" or "voicing".
Do you want Non polar electrolytics (which is what those appear to be) or something more upscale like poly or film caps?
On the cheap, Dayton NPE caps from Partsexpress would work, they come in 5% or 1% ratings, can't tell what yours are but just guessing 10% or 20% ( +/-variance from the rated uf).
The other figure may be 50 volts, higher volts is ok for replacement.

Let's just use these numbers as examples. With a base number of 100, 1% is 99-101, at 5% it would be a range of 95-105. At 10% the range would be 90-110.
The smaller the % the closer a cap is to it's rated uf. Too far from the rated uf both performance and sound quality can be affected. Some people might say 10% might be good enough for a vast range of speakers but 5% is better, and 1% would be very close to the rated value. Possibly more important with "better" speakers and a better system.
Google gets me pretty much nothing about your speakers, could be they are very rare (could be quite good) or else possibly rack system speakers (not that great generally) or possibly sold mostly overseas.
Generally the larger a cap rating the more it costs, since it appears you need two 1uf caps the cost may not be all that much. A good middle of the road might be to go with poly caps. Many brands and even models/series of caps to choose from.
Polypropylene caps might be larger than NPE (non polar electrolytic), and film caps even larger (and generally more $), for the same uf rating. It looks like you would have enough room to place two 1uf film caps in the space available, I just don't know if film caps would make sense in those particular speakers, hopefully someone with knowledge of those particular speakers or experience with caps in general will add to this discussion.
Another factor that may influence choice of type and price of caps is how good is the rest of the system.

You can literally search the various brands and types of caps until your eyes bleed and your brain hurts.
Here's a link to Parts-express 1.0uf caps. https://www.parts-express.com/Search.aspx?keyword=1.0uf capacitor&sitesearch=true
They range from 53 cents to $49. Plus shipping. Don't forget you need 4 of them
Are your speakers worth $2.12, probably yes.
Are they worth $196, I can't say.
And that's only one source out of many.

Thanks by the way
Thanks for the link. It’s just that I don’t know how to choose between polypropylene, standard, silver, film, foil? Does that matter?

Was going to pair them up with a Sony STR-7065 and a Yamaha YP-211 turntable I have kicking around. I might try some poly ones. But I’ll wait and see if I get any other information here. Thanks again.
Yes two caps per speaker.all the same. Photo #1 above. Woofer looks to run full range Photo #2 above

I can't find any reference anywhere that would indicate that these are "special" speakers, so unless they have great sentimental value I'd put in some NPE's at less than a buck, or maybe polypropylene at a couple bucks each.
NPE's* should give you at least "as good" of sound as they originally had (provided everything else in the speaker is working correctly) and there might be an improvement by going with polypropylene caps.
I can't see putting $200 caps in $50 speakers, but that's JMO.
Quick search of your receiver indicates it should be pretty good, and the speakers might be a good match as they may be from around the same time frame.
* gasp * do I dare open this can of worms...aw heck....you could buy small value film caps to use as bypass caps with the NPE's...would add less than a fiver to the cost.

Non polarized electrolytic, that is the type your current capacitors are. A large percentage of speaker capacitors are non polarized, which means there is no positive or negative end.
NPE's can be placed into the circuit without worry about which end is which. With polarized capacitors hooking them up wrong can cause problems, often big problems. Not the case with NPE's.
You could Google " bypass caps audiokarma " if you want to learn more.
Some people say they do good things for the sound, some people say they don't do much if anything.
