Gary,
If the value is not too critical you can make your own bipolar by using two 100µF caps.
Connect them in series but tie both negative legs together and use both positive legs as the terminals.

Hi,
is it 0.47mfd or 47mfd or 0.47uF or 47uF?
If it is only 0.47 then a 100V plastic film can be used. This might change the sound for the better or worse.
If 47uF then 100V bi-polar electrolytics are available. My Rapid catalogue shows them at £0.19 each. You could use a motor start, plastic film cap here if you want the highest spec but they are very bulky and expensive.

Hi,
is this another US manufacturer mis-using mfd when they mean micro farad (uF)
47uF 100V bipolar are readily available. It cannot be 47,000uF 100V or could it?
Panasonic are reputedly very good but many others are out there.

These guys carry Bennics, though the closest value they stock to 47uF seems to be 50uF.

50 uF is close enough. Many caps are rated ±10% and then listed for the top end of that range. In other words, a 50 uF cap could "really" be a 47 or even 45 uF.
As I recall the original poster listed this cap as being in the tweeter circuit. 47 uF is a very large value for that location in a schematic. I think that 4.7 uF would be closer to what is needed.
Or, is this a 3-way speaker and the cap is in the midrange driver circuit.?
Also, how do you know this cap needs to be replaced? Did you test it?

Hi! I have some SIEMENS capacitors 10000uF/40V type:
Al-Elko rauh IIA
B41306-J7106-T
They have five terminals, four of then marked 1 to 4, and the fifth marked with a minus sign.
Question: to use the full capacity I must connect all 1 to 4 terminals, or it is sufficient to connect the minus terminal and one of the 4 terminals?
Could you send me a data sheet for this capacitor?
Thank you, in advance, for your early answer, at hmarinescu@gmail.com

You can easily discovery the internal arrangements with an ohmeter for continuity (or not) between 1 to 4 and a C meter ....
