Need advice on modifying my Diva Swan M200's

[owdi]

I picked up a pair of Diva Swan M200's for my computer about two years ago, and have recently added a subwoofer to fill in the low end. The subwoofer has an active lowpass crossover, but I don't have a highpass crossover for the Diva's.

Just for fun, some picutures:

I do have a pair of 200mfd capacitors, and the Diva's are 8ohm speakers. Theoretically, if I wire them up in series with the midrange, I should get a first order highpass crossover at 100hz.

The capacitors have the following writing on them: Bennic Non-Polar 200 MFD 100WV

Is there any reason why I shouldn't do this? I don't want to release any magic smoke from anything....
