bi-amp with a tube amp and SS


Is there any body who experieced biamping with a tube amp for low frq. and SS for high freq.

I think same power (watt) is not a must, is that true?

What if I use mono tubes for uppers and stereo SS for lows do I need to mach sensitivities again or what?
If the sensitivities aren't matched, which they most likely will not be, you can just buy a pair of in-line attenuators like EVS to match them externally. You would only need one pair, placed on the more sensitive amp(s).

Like these.
