blown capacitor in Harbeth speaker - help


I bought a pair of Harbeth HL-PSES-2 off Ebay. That was first mistake lol.

Anyway, after hearing some distortion coming from a speaker when I had some very low notes playing on my system, I decided to take it to a sound engineer. He said the capacitor in the speaker was toast. He said in his opinion I would be better off trying to get my money back than replacing the capacitor. Is his advice accurate or is possible to replace the capacitor and still get a great sound of out them. I really love the sound of my speakers (except for the one speaker which will continue to likely get worse.) Any suggestions would be greatly appreciated! - thanks!

Thanks for most of the replies.

I had switched speakers and the same speaker that I had issues with displayed the same distortion. So it was definitely the speaker - not the system, which I had thought might have been the problem at the start.

I spoke to Fidelis today and they believe it's the woofer. They can replace it. Even though they are likely correct, I am going to have one other sound engineer take a look at it before shipping it to them for repair. The cost they are looking for is not that bad and the person who sold me the speakers said she would cover the repair. I just don't want to ship them again if I can have a simple repair.

Thanks for your insights. Will post when I have them sounding new again.
