Hello! 

 

First I am sorry for writing in English. 

 

 

5 days ago a friend of my bring me a pair of 22rh532. I was not expecting such detailed, nice sound from a set of active speakers from 1974. I am surprised. My main setup up is  Creek power amp, Epos speakers. I also hook a Luxman receiver to my Epos speakers also. I mean I already have a nice setup but these 22rh532s was totally surprising. 

 

I am considering recapping them. They sound good but I am pretty sure that recapping them will make them sing better. If anyone would like to share do's and don'ts list I would like to listen. 

 

And I would like to also ask your opinion about AD0160Ts. I could hear highs better and I googled the tweeter of my 532  but this article made ( http://www.troelsgravesen.dk/WWDT.htm) me a little bit confused. Are AD0160Ts really a very bad choice? I mean they are already sounding nice to my ears, but if there is a room for improvement I would definitely try to improve the sound of these speakers. 

 

Thank you very much

 

Emre

Hi Emre,

Nice to read that you value the 532, it will be quite different than passive speakers you knew so far.
The recap might change a little, best audible results come from changing the cheap, small ones. (values between 4,7 uf and 470 uf).
Mainly the 4,7 uf capacitors could harm your sound. A bad 330uf capacitor could cause your box to remain in stby.
A don't is buying / changing all its capacitors and discovering that the sound hardly changed. Consider to replace the big capacitors if you see growing leakage on its terminals (yellow/black)
The ad0160 tweeter is a special one, some like it and soms think it is a little too noisy. You could consider mounting two AD0163 types.
And in stead of spending a lot on new capacitors you coud look out for a slightly newer model mfb : 22RH544.
These have newer tweeters if your modelnumber is 22RH544/00R series PL02 or higher like 22RH544/50R PL... or 22RH54400R PL03...

@herman thank you very much! ad0160 or not I am enjoying the highs! I was surprised to read the article about them. 

 

The serial numbers I have seems to be 22RH532/00P PL11981, so I guess I have older tweeters? Or not, I am enjoying them 🙂 

 

I will continue listening without a recap for a while I guess since they sound just fine. When problems arise I know where to start. 

 

Thank you!
