Please identify this capacitor
« on: 13 Mar 2009, 01:35 am »
Does anybody know what brand of film cap is this? It's in my Ushers. I know it's 12uF 5% tolerance. I want to upgrade them but curious what they are.


Thanks!

It looks just like a Bennic/Dayton cap.

Thanks, it does look like Bennic, except for the writing - which could just be their OEM version. Bennic is made in Taiwan too, which is where the Ushers are assembled. And the coils and resistors look the same as Bennic parts too. I have written to them to ask if they can claim it.
Thanks face!

Any other opinions are welcome!
Thanks

I was going to say it is an OEM of some, likely Asian, cap manufacturer.  It very well could be Bennic.  Its hard to know for sure.

Looks like you have the info you need though, as far as replacing it.  You know the value and you know the voltage rating.  That should suffice.

Thanks Josh, you are right. It is AID Electronics of Taiwan.

I just wanted to make sure they really were econocaps before I replace them.  Still having trouble accepting that high end speaker mfgs put this stuff in their products. But there it is.

Which Usher model is that cap from?

It's from the top of the Usher line,the Be-20.
It is a polypropylene capacitor, in past years loudspeakers were lucky to have mylar caps with steel leads
instead of non-polarized electrolytic capacitors.

So Usher is high end?

I don't see that there's anything wrong with that cap. It's well suited for the application. Polypropylene caps work extremely well in speaker crossovers.

At $18,860 / pair US,they might be,but I have not heard them. turkey,you have now ventured into the not all caps are created equal zone. A substantial improvement in the sound of the Be-20 may be possible if the caps and coils are replaced with superior parts. This presumes that any extra information passed by the parts isn't lost in the internal wiring or the complexity inherent in the circuit. If it gets that far it can still get stopped by the drivers themselves. These caveats aside it is still a worth while experiment that for the dollars spent may yield a nice dividend in improved resolution.
The key when doing a mod like this is to not throw the stock parts out.
  If the increased resolution of the improved loudspeaker lets nasties through from upstream components you can always dumb the system back down by reinserting the stock parts.
Sometimes that cherished front end isn't as good as you thought it was and needs improvement as well. The biggest mistake made in these situations is to shoot the messenger.

I would suggest replacing the cable from the crossover to the drivers before altering capacitors. I have replaced the thoroughly rubbish wire in my speakers with Kimber and the difference was very great indeed. Also less likely to alter the balance of the speaker.
    Unfortunatley knowing the simple value of the capacitor is not enough to know that a replacement will work in a crossover. A capacitor behaves with different characteristics dependant upon frequency of charge/discharge and of course temperature and resistance/impedance will be less in a high quality cap. If you replace with an audiophile capacitor I would suggest replacing all the components together as reducing charge/discharge time in one cap and not in others will not show the improvement fully and possible 'alter' the crossovers behaviour. Cheers, Browntrout.
   Good luck and do let us know how you get on. To be honest the best caps are Blackgate and Elna Cerafine, Mundorf I have found to be rather sterile in nature. All will of course sound alot better than what the manufacturer used though the internal cable will make a huge difference if replaced with proper speaker cable.
  Once you hear something made with Blackgates and Shinko/AudioNote Tantalum resistors throughout you realise that most ''HiFi'' isn't very tonally truthfull at all.
