Wanted for rebuild

[Eighthnote]

Hello all, I have 4 Sansui SP-2500x cabinets I'm going through. My objective is to test the individual speakers and the crossovers so I can assemble 2 fully functional cabinets.
This is a quite the puzzle as I have found all the S-134 mid-range speakers are dead. All the S-136 mid range speakers test good. Is this a coincidence or am I overlooking something obvious?
Any opinions on that would be greatly appreciated.
My next question (since I can't seem to find any S-134s) does anyone know a good replacement that I wouldn't have to re-wire or alter the cabinets? Maybe some day I'll run across the original S-134 someday. There's plenty of S-136s out there but the S-134s are elusive. Yes, there are two mid-range speakers in each cabinet but they're not the same speaker. They are wired in parallel but they are designed a little different. Won't go into that unless someone is interested.
I've looked at quite a few sights and the S-134 are nowhere to be found.
Summarizing: Why are all the S-134 dead but not the S-136?
Any direct replacements? 5 1/8 Mid-range cone type 13.5 ohms 16w Frequency Response 1K-4Khz
Cheers........

Won't go into that unless someone is interested.

what would make this thread interesting is photos of the speakers.....

1) overall front & back, with and without the grills

2) overall rear interior showing all of the drivers

3) individual photos of the drivers

4) photos of the crossovers

also, how did you test the individual drivers?

Hello, thanks for the response. Let me try to answer your concern.
The SP-2500X has one of each of the speakers in the pics. The S-136 with the open backs are all good.
The S-134 is dead.
I checked the ohms with a multi-meter
I checked the continuity with a multi-meter.....
I also did the 9v battery test.
The S-134 failed all three test.
I have not dug into the crossovers yet but other than the closed back mid-range, the speakers work fine so I'm assuming the most I'll have to do on the cross overs is maybe upgrade the 45 year old capacitors.

Have you looked on the auction site? If you do a search for sold S-134's, three sold the last one earlier in October. Maybe you are just going to have to be patient before they turn up. Not sure if there is anyone who rewinds voice coils for them.

Hello, thanks for the response. Let me try to answer your concern.

I don't have any concerns, I simply want to see what your speakers look like, not just the midranges

if the 134's and 136's are the same size, I would use the 136's and put some duct tape over the openings in the frame

Probably will do something like that because the S-134s are next to extinct unless they're in someone's cabinets. I'll keep my eye out but...........
The issue with using two of the S-136's they are different ohm and different frequency response than the 134's. Since they're wired in parallel I don't think it would harm anything. I know these speakers aren't state of the art and many folks don't like them but they sound great with my Sansui 9090.
I rarely take the 9090 past 2 or 3.
I still have no clue why all the S-134's died and all the S-136's are alive and well. Unless the design of the 134's just had a built in shorter life span.
While I hunt I'm going to try both scenarios. Use 2 of the working speakers in each cabinet and just leaving the bad speaker out all together. The grills cover up the hole. But I'll know.........
Thanks for taking the time to ring in...........Cheers............
