hopefully the op can sort through another typical a-gon thread, lots of pretty good advice, some heavy handedness in how it is delivered, some getting caught up with semantics and missing the point
i suggest op take away the following:
1 - you have definitely chosen pretty inefficient, relatively hard to drive speakers - if you like them and will run with them, you will need to match your amplifier carefully, most likely a beefy solid state unit to deliver alot of power/current to do the job well esp. if you like to play pretty loud
2 - most tube amps will struggle with driving your speakers, in absolute volume and in bass control -- tube amps just can’t match ss equivalents in bass control and slam, you need to go to megabuck tube amps to get very good bass with your speakers
3 - tube pre feeding ss power amp likely the best solution if you want some tube dimensionality and sweetness to the sound, that is IF you value that
4 - tube watts vs ss watts and the semantics associated with that line of discussion is pretty much irrelevant
