New Amp or New Subwoofer

I have an older Klipsch sub 10, that I want to integrate into my Home Theater as a second sub.
But the internal Amp is broken. My question, do I get an external Amp(was thinking a lower end Crown) or a new Subwoofer. My Budget is around 300€.
Thanks is advance

Is your other sub the same model?

No, it’s a Mivoc 10 inch sub.

You could just get another one of those for matching subs to use in stereo, it should work just fine. I don’t know if it would be worthwhile reamping your klipsch sub unless you can find a used or replacement amp module somewhere
